Fibrin application for preventing lymphocysts after retroperitoneal lymphadenectomy in patients with gynecologic malignancies.

OBJECTIVE: We performed a randomized, prospective trial to assess the impact of fibrin glue on the incidence of lymphocysts after systematic pelvic or pelvic and paraaortic lymphadenectomy in patients with gynecologic malignancies. METHODS: Ninety-three consecutive patients with gynecologic pelvic malignancies who underwent surgery including pelvic or pelvic and paraaortic lymphadenectomy were randomized during surgery to be treated with fibrin glue or not. Serial computed tomography (CT) scans were performed during follow-up. CT findings of a smooth and thin-walled cavity filled with a water-equivalent fluid, sharply demarcated from its surroundings and without signs of infiltration were interpreted as lymphocysts. RESULTS: Forty-seven patients (51%) were treated with fibrin glue and 46 (49%) were not. All 93 patients underwent pelvic lymphadenectomy; 15 patients (32%) of the fibrin group and 12 (26%) of the controls also underwent paraaortic lymphadenectomy. We found no significant differences between patients who received fibrin glue and those who did not. CONCLUSION: Intraoperative application of fibrin glue did not reduce the rate of postoperative lymphocysts after lymphadenectomy and had no impact on any follow-up parameter. Its use seems not to be indicated in systematic gynecologic pelvic or pelvic and paraaortic lymphadenectomy.     

Chylous Ascites After Laparoscopic Lymph Node Dissection in Gynecologic Malignancies

Study ObjectiveTo evaluate the clinical presentation, epidemiology, risk factors, and treatment of chylous ascites after laparoscopic lymphadenectomy to treat gynecologic malignancies.DesignRetrospective study with review of outcomes (Canadian Task Force classification II-3).SettingUniversity research hospital.PatientsFrom November 2009 to December 2012, 997 patients underwent laparoscopic lymphadenectomy to treat gynecologic malignancies at our hospital.InterventionsPostoperative chylous ascites resolved with continuous drainage and dietary restriction or fasting.Measurements and Main ResultsNine of 997 patients (0.9%) developed chylous ascites postoperatively. Mean age of these 9 patients was 47.5 years. Median time from operation to development of chylous ascites was 4 days (range, 2–9 days). Chylous ascites developed on either day 1 in 6 patients, day 2 in 2 patients, and day 8 in 1 patient, after food intake. We found that postoperative chylous ascites was associated more with para-aortic lymphadenectomy than with pelvic lymphadenectomy (overall incidence, 0.9%; 4.08% in the para-aortic lymphadenectomy group vs 0.35% in the pelvic lymphadenectomy group). In all patients, chylous ascites resolved with conservative treatment. Median time to resolution was 7 days (range, 3–9 days). Drainage tubes were removed within 9 days after treatment.ConclusionsThe incidence of chylous ascites after laparoscopic lymphadenectomy was 0.9%. Para-aortic lymphadenectomy was associated with postoperative chylous ascites. Chylous ascites was successfully treated with conservative management. An abdominal drainage tube can be a simple and effective approach and should be considered in the treatment of chylous ascites.     

Ultrasound characteristics of a symptomatic and asymptomatic lymphocele after pelvic and/or paraaortic lymphadenectomy

ObjectiveTo describe the sonographic characteristics of a lymphocele after pelvic and/or paraaortic lymphadenectomy for gynecological malignancy, analyze and identify ultrasound characteristics related to the symptomatic and asymptomatic lymphoceles.Materials and methodsThis is a retrospective analysis of ultrasound examination data collected consecutively in patients after pelvic and/or paraaortic lymphadenectomy in one institution. We recorded the number of lymphoceles, localization, size; ultrasound morphology following International Ovarian Tumor Analysis group classification and symptoms.ResultsWe described and analyzed 227 lymphoceles (150 asymptomatic and 77 symptomatic) in 161 patients. The asymptomatic lymphocele is typically a thick-walled cystic lesion without vascularization, round and unilocular with anechoic or ground-glass content. The symptomatic lymphocele is typically an oval, or ovoid, unilocular lesion with low-level or anechoic content (ground glass content is unlikely to be present, p < 0.001) and the presence of debris and septations. The lymphocele size (p = 0.001), number of lymphoceles (>1) (p = 0.005), septa (p = 0.002), and debris (p < 0.001) were independent ultrasound features correlating to symptoms development. More than one lymphocele (p = 0.047), septations (p = 0.007) and presence of debris (p < 0.001) were independent ultrasound features correlated to infection.ConclusionUltrasound features of symptomatic and asymptomatic lymphocele differ. The clues for lymphocele differential diagnosis are the history of lymphadenectomy and the finding cystic lesion with typically ultrasound features of lymphocele, adjacent to great pelvic vessels. Unique ultrasound features of lymphocele may help to distinguish from tumor relapse, hematoma, abscess, seroma or urinoma.     

Surgical Approach and Use of Uterine Manipulator Are Not Associated with LVSI in Surgery for Early-stage Cervical Cancer

Study ObjectiveIn 2018, the Laparoscopic Approach to Cervical Cancer trial reported that patients undergoing minimally invasive surgery for cervical cancer (CC) had poorer outcomes than patients undergoing open surgery. Several hypotheses have been made to explain the results. We aimed to investigate whether laparoscopic procedures and use of a uterine manipulator increase the risk of lymphovascular space invasion (LVSI) in early-stage CC.DesignA retrospective study.SettingA Chinese women's and children's hospital.PatientsPatients with early-stage CC who underwent radical hysterectomy in West China Second University Hospital between April 2019 and May 2020.InterventionsLaparoscopic surgery (with uterine manipulator and uterine manipulator-free) and open surgery.Measurements and Main ResultsA total of 979 patients diagnosed with CC were registered in West China Second University Hospital for surgical treatment. Of these, 525 patients underwent laparoscopic surgery and 454 patients underwent open surgery. In total, 735 patients with early-stage cancer underwent radical hysterectomy and pelvic lymphadenectomy, including 357 by laparoscopic surgery and 378 by open surgery. For those who underwent radical hysterectomy and pelvic lymphadenectomy, the incidence of LVSI was 48.41% and 47.34% in laparoscopic and open groups, respectively (p = .771). After 1:1 propensity score matching with age, International Federation of Gynecology and Obstetrics stage, pathology, and tumor size, the incidence of LVSI was 45.54% and 51.79% in laparoscopic and open groups, respectively (p = .186). Subdividing the laparoscopic group into uterine manipulator and uterine manipulator-free groups, the incidence of LVSI was 45.22% and 48.35%, respectively (p = .580). After propensity score matching with age, International Federation of Gynecology and Obstetrics stage, pathology, and tumor size, the incidence of LVSI was 45.78% and 55.42% in these 2 groups, respectively (p = .214). Multiple factor analysis revealed that lymph node metastasis and deep stromal invasion were associated with LVSI (p value <.05 in both groups).ConclusionThe surgical approach and use of a uterine manipulator are not associated with LVSI in surgery for early-stage CC. Lymph node metastasis and deep stromal invasion are associated with LVSI.     

Total laparoscopic radical hysterectomy and pelvic lymphadenectomy using harmonic shears

STUDY OBJECTIVE: To describe the feasibility and outcome of total laparoscopic radical hysterectomy with or without pelvic lymphadenectomy for patients with stage I cervical cancer or severe pelvic endometriosis using harmonic shears as the sole instrument for dissection, division, and maintenance of hemostasis of all major surgical pedicles. DESIGN: Retrospective review (Canadian Task Force classification II-2). SETTING: University hospital and affiliate institutions. PATIENTS: Seven patients who underwent total laparoscopic radical hysterectomy using harmonic shears for International Federation of Gynecology and Obstetrics stage IA2 to IB1 cervical cancer and pelvic endometriosis at our institution or affiliate hospital from January 2004 through February 2005. INTERVENTION: A retrospective review of patients that underwent total laparoscopic radical hysterectomy with or without pelvic lymphadenectomy at our institution using harmonic shears was performed. Information regarding preoperative, intraoperative, and postoperative events was recorded and analyzed. MEASUREMENTS AND MAIN RESULTS: Pelvic lymphadenectomy was performed in all cancer cases. Mean patient age was 40 years (range 30-53 years). Mean estimated blood loss was 143 mL (range 100-200 mL). Mean operating time was 293 minutes (range 255-385 minutes). Mean pelvic node count was 27.8 (range 24-34) for cancer cases. Mean hospital stay was 3.2 days (range 2-7 days). One patient developed a vaginal cuff abscess postoperatively that was managed conservatively with drainage in the office setting followed by intravenous antibiotics. Another patient developed urinary retention for 2 weeks after surgery. There were no other intraoperative or postoperative complications. CONCLUSION: Total laparoscopic radical hysterectomy with pelvic lymphadenectomy using harmonic shears is a technically feasible and safe procedure. Larger studies and long-term follow-up are required to determine the oncologic outcomes of these patients.     

Laparoscopic para-aortic lymphadenectomy in advanced cervical cancer: morbidity and impact on therapy

BackgroundLaparoscopic para-aortic lymphadenectomy (PAL) is being used increasingly to stage patients with locally advanced cervical cancer (LACC) and to define radiation field limits before chemoradiation therapy (CRT). This study aimed to define clinical implications, review complications, and determine whether surgical complications delayed the start of CRT.Patients and methodsWe retrospectively reviewed a continuous series of patients with LACC, with no positive para-aortic (PA) nodes on positron emission tomography-computed tomography (PET-CT) and who had undergone a primary laparoscopic PAL.ResultsFrom November 2007 to June 2010, 98 patients with LACC underwent pretherapeutic PAL. Two patients did not undergo PAL: extensive carcinomatosis was discovered in one case and a technical problem arose in the other. No perioperative complications occurred. Seven patients had a lymphocyst requiring an imaging-guided (or laparoscopic) puncture. Eight patients (8.4%, which corresponds to the false-negative PET-CT rate) had metastatic disease within PA lymph nodes. In cases of suspicious pelvic nodes on PET-CT, the risk for PA nodal disease was greater (24.0% versus 2.9%). When patients with and without surgical morbidity were compared, the median delay to the start of treatment was not significantly different (15 days; range, 3–49 days versus 18 days; range, 3–42 days).Discussion and conclusionsThe morbidity of laparoscopic PAL was limited and the completion of treatment was not delayed when complications occurred. Nevertheless, if PET-CT of the pelvic area is negative, the interest in staging PAL could be discussed because the risk for PA nodal disease is very low.     

Low-grade endometrial stromal sarcoma: A Turkish uterine sarcoma group study analyzing prognostic factors and disease outcomes

ObjectiveTo investigate factors associated with refractory disease, recurrence, or death as well as disease-free survival (DFS) and overall survival (OS) in low-grade endometrial sarcoma (LGESS).MethodsA multi-institutional, retrospective study was conducted in a total of 124 patients, who received a curative-intent surgery. The exclusion criteria were as follows: i) history of any other invasive disease; ii) neoadjuvant therapy; iii) fertility sparing surgery; iv) a different diagnosis after review of the slides.ResultsAll patients underwent hysterectomy, 96% had bilateral salpingo-oophorectomy, and 65% had lymphadenectomy. Twelve (14.8%) of 81 patients undergoing lymphadenectomy had lymph node (LN) metastasis. Of those, 8 (9.8%) had pelvic LN metastasis whereas 4 (5.6%) had isolated paraaortic LN metastasis. Six of 8 (75%) patients with positive pelvic LNs had concurrent paraaortic LN metastasis. Among 124 patients, 3 patients (2.4%) had refractory disease following primary therapy. During a median follow-up of 45.5 months, 27 (22.3%) of 121 patients who achieved complete remission after primary therapy developed recurrence, and 10 patients (8.1%) died of disease. The 3-year DFS and OS were 76.9% and 93.8%, respectively. Stage was the sole independent prognostic factor in the whole cohort. When analyzing factors within subgroups of stage I and stage ≥II, there was no significant prognostic factor for stage I; however, lymphadenectomy and adjuvant chemotherapy were significantly associated with disease outcomes for stage ≥II. While lymphadenectomy was related with improved DFS, chemotherapy was associated with poor DFS and OS.ConclusionThe risk of LN metastasis at pelvic as well as paraaortic lymphatic basins is not negligible to omit lymphadenectomy in stage ≥II LGESS. Moreover, lymphadenectomy provides significant DFS advantage in patients with extrauterine disease.     

Is there any therapeutic role of pelvic and para-aortic lymphadenectomy in apparent early stage epithelial ovarian cancer?

ObjectiveThe therapeutic role of pelvic and para-aortic lymphadenectomy in surgical staging of apparent early-stage epithelial ovarian cancer (eEOC) is still under debate. The aim of this study was to evaluate the potential therapeutic role of systematic lymphadenectomy in patients with eEOC.MethodsMulti-center retrospective cohort study, comparing women with apparent eEOC who underwent comprehensive bilateral pelvic and para-aortic lymphadenectomy (defined as ≥20 lymph nodes) versus patients receiving no lymphadenectomy or lymph node sampling, from 05/1985 to 12/2016. Patients with bulky nodes at CT-scan and those without complete intra-peritoneal surgical staging were excluded. Only patients who received at least 3 cycles of platinum-based adjuvant chemotherapy were included.ResultsOut of 2559 patients with FIGO stage IA-IIIA1 ovarian cancer, 639 (25.0%) met inclusion criteria. 360 (56.3%) underwent comprehensive lymphadenectomy, 150 (23.5%) lymph node sampling and 129 (20.2%) no lymphadenectomy. Patients who underwent comprehensive lymphadenectomy were younger (p < 0.001), experienced a higher number of severe post-operative complications (p = 0.008) and had a longer time to start chemotherapy (p = 0.034). There was no difference in intra-operative complications. Median follow-up was 63 months (range, 5–342). The 5-year disease-free survival (DFS) was 79.7% vs. 76.5% vs. 68.3% (p = 0.006), and 5-year overall survival (OS) was 92.3% vs. 94.5% vs. 89.8% (p = 0.165) in women who received comprehensive lymphadenectomy vs. lymph node sampling vs. no lymphadenectomy, respectively. Lymphadenectomy represented an independent factor for DFS improvement, HR 0.52 (95%CI 0.37–0.73) (p < 0.001).ConclusionPelvic and para-aortic lymphadenectomy in surgical staging of eEOC improves DFS for the price of increasing post-operative complications and time to chemotherapy but does not affect OS. Better understanding of tumor biology may help to identify those patients in whom lymphadenectomy should still play a role.     

Number of Removed Pelvic Lymph Nodes as a Prognostic Marker in FIGO Stage IB1 Cervical Cancer with Negative Lymph Nodes

Study ObjectiveTo investigate whether the number of removed lymph nodes (RLNs) influences the clinical outcome of stage IB1 cervical cancer on the premise of uniform pelvic lymphadenectomy.DesignRetrospective cohort study.SettingObstetrics and Gynecology Hospital of Fudan University.PatientsWomen (n = 782) with stage IB1 cervical cancer.InterventionsLaparoscopic radical hysterectomy and uniform pelvic lymphadenectomy (common iliac, external iliac, internal iliac, obturator) for stage IB1 cervical cancer. The median time of follow-up was 64.7 months (range, 4.3–102.8).Measurements and Main ResultsOf 782 patients with stage IB1 cervical cancer, the median number of pelvic RLNs was 19 (range, 7–49). Twenty-one patients (2.7%) had RLNs ≤ 10, 461 (59.0%) had 11 to 20, 263 (33.6%) had 21 to 30, and 37 (4.7%) had RLNs ≥ 31. The differences were not statistically significant in the clinicopathologic characteristics between the 4 groups (p >.05). In the multivariate analysis, pelvic RLN number became an independent prognostic factor for progression-free survival (PFS) and cancer-specific survival (CSS) in stage IB1 cervical cancer (p = .029; .015 for CSS and PFS). After the stratified analysis by lymph node metastasis, RLN number remained an independent predictive value (p = .026 for CSS, p = .012 for PFS) in patients with negative pelvic lymph nodes. Moreover, patients with RLN number ≤ 10 carried a 5.550-fold higher risk for progression (p <.001) and 5.596-fold greater likelihood of death (p = .001) than those with RLN number > 10 in case of no lymph node metastasis.ConclusionWith uniform pelvic lymphadenectomy, the total pelvic RLN number could be a valuable predictor of outcome in stage IB1 cervical cancer without lymph node metastasis during a follow-up of at least 5 years.     

The use of fibrin sealant (Tisseel) in laparoscopic excision of ovarian endometrioma

Learning curve and surgical outcome for robotic-assisted hysterectomy with lymphadenectomy: case-matched controlled comparison with laparoscopy and laparotomy for treatment of endometrial cancer

Study ObjectiveTo determine the learning curve for robotic-assisted hysterectomy with lymphadenectomy for surgical treatment of endometrial cancer.DesignAn analysis of robotic-assisted hysterectomy with lymphadenectomy vs total laparoscopic hysterectomy with lymphadenectomy and laparotomy with total abdominal hysterectomy with lymphadenectomy (Canadian Task Force classification II-1).SettingSolo, experienced, minimally invasive gynecologic oncology practice in a tertiary hospital.PatientsOne hundred forty-eight patients including 56 patients who underwent robotic-assisted hysterectomy with bilateral pelvic and paraaortic lymph node dissection, 56 patients who underwent total laparoscopic hysterectomy with bilateral pelvic and paraaortic lymph node dissection, and 36 patients who underwent traditional total abdominal hysterectomy with bilateral pelvic and paraaortic lymph node dissection performed by the same surgeon for treatment of endometrial cancer.InterventionsRobotic-assisted hysterectomy with bilateral lymphadenectomy, total laparoscopic hysterectomy with bilateral lymphadenectomy, and traditional total abdominal hysterectomy with bilateral lymphadenectomy were performed. Data were categorized by chronologic order of cases into groups of 20 patients each. The learning curve of the surgical procedure was estimated by measuring operative time with respect to chronologic order of each patient who had undergone the respective procedure.Measurements and Main ResultsFor the 3 surgical procedures, data analyzed included mean age, body mass index, operative time, blood loss, lymph node retrieval, and complications. Mean (SD); 95% confidence interval [CI]) operative time for the 3 procedures was statistically significant: 162.5 (53) minutes (95% CI, 148.6–176.4]), 192.3 (55.5) minutes (95% CI, 177.6–207.0), and 136.9 (32.3) minutes (95% CI, 126.3–147.5), respectively. Analysis of operative time for robotic-assisted hysterectomy with bilateral lymph node dissection with respect to chronologic order of each group of 20 cases demonstrated a decrease in operative time: 183.2 (69) minutes (95% CI; 153.0–213.4) for cases 1 to 20, 152.7 (39.8) minutes (95% CI, 135.3–170.1) for cases 21 to 40, and 148.8 (36.7) minutes (95% CI, 130.8–166.8) for cases 41 to 56. For the groups with laparoscopic hysterectomy with lymphadenectomy and traditional total abdominal hysterectomy with lymphadenectomy, there was no difference in operative time with respect to chronologic group order of cases. There was a difference between the number of lymph nodes retrieved between robotic-assisted hysterectomy with bilateral lymphadenectomy (26.7 [12.8]; 95% CI, 23.3–30.1) compared with laparoscopic hysterectomy with bilateral lymphadenectomy (45.1 [20.9]; 95% CI, 39.6–50.6) and traditional total abdominal hysterectomy with lymphadenectomy (55.8 [23.4]; 95% CI, 48.2–63.4). The rate of intraoperative complications for laparoscopic hysterectomy with bilateral lymphadenectomy was 12.5% (7 of 56) compared with 0 % for robotic-assisted hysterectomy with bilateral lymphadenectomy. The rate of postoperative complications was 14.3% (8 of 56), 21.4% (12 of 56), and 19.4% (7 of 36), respectively, for the 3 groups. There was less blood loss with robotic-assisted hysterectomy with bilateral lymphadenectomy (89.3 [45.4]; 95% CI, 77.4–101.2) compared with laparoscopic hysterectomy with bilateral lymphadenectomy (209.1 [91.8]; 95% CI, 185.1–233.1) and traditional total abdominal hysterectomy with lymphadenectomy (266.0 [145.1]; 95% CI, 218.6–313.4). Duration of hospitalization was shorter in the group with robotic-assisted hysterectomy with bilateral lymphadenectomy (1.6 [0.7]; 95% CI, 1.4–1.8) compared with the groups who underwent laparoscopic hysterectomy with bilateral lymphadenectomy (2.6 [0.9]; 95% CI, 2.4–2.8) or traditional total abdominal hysterectomy with lymphadenectomy (4.9 [1.9]; 95% CI, (4.3–5.5).ConclusionThe learning curve for robotic-assisted hysterectomy with lymph node dissection seems to be easier compared with that for laparoscopic hysterectomy with lymph node dissection for surgical management of endometrial cancer.     

Laparoscopic Debulking of Enlarged Pelvic Nodes during Surgical Para-aortic Staging in Locally Advanced Cervical Cancer: A Retrospective Comparative Cohort Study

Study ObjectiveTo evaluate laparoscopic pelvic lymph node debulking during extraperitoneal aortic lymphadenectomy in diagnosis, therapeutic planning, and prognosis of patients with locally advanced cervical cancer and enlarged lymph nodes on imaging before chemoradiotherapy.DesignRetrospective, multicenter, comparative cohort study.SettingThe study was carried out at 11 hospitals with specialized gynecologic oncology units in Spain.PatientsTotal of 381 women with locally advanced cervical cancer and International Federation of Gynecology and Obstetrics 2018 stage IIIC 1r (radiologic) and higher who received primary treatment with chemoradiotherapy.InterventionsPatients underwent pelvic lymph node debulking and para-aortic lymphadenectomy (group 1), only para-aortic lymphadenectomy (group 2), or no lymph node surgical staging (group 3). On the basis of pelvic node histology, group 1 was subdivided as negative (group 1A) or positive (group 1B).Measurements and Main ResultsFalse positives and negatives of imaging tests, disease-free survival, overall survival, and postoperative complications were evaluated.In group 1, pelvic lymph node involvement was 43.3% (71 of 164), and aortic involvement was 24.4% (40 of 164). In group 2, aortic nodes were positive in 29.7% (33 of 111). Disease-free survival and overall survival were similar in the 3 groups (p = .95) and in groups 1A and 1B (p = .25). No differences were found between groups 1 and 2 in intraoperative (3.7% vs 2.7%, p = .744), early postoperative (8.0% vs 6.3%, p = .776), or late postoperative complications (6.1% vs 2.7%, p = .252). Fewer early and late complications were attributed to radiotherapy in group 1A than in the others (p = .022).ConclusionLaparoscopic pelvic lymph node debulking during para-aortic staging surgery in patients with locally advanced cervical cancer with suspicious nodes allows for the confirmation of metastatic lymph nodes without affecting survival or increasing surgical complications. This information improves the selection of patients requiring boost irradiation, thus avoiding overtreatment of patients with negative nodes.     

Synthetic cyanoacrylic glue in the prevention of post-operative lymphocele after pelvic lymphadenectomy in patients with uterine malignancies: A prospective,single-blind,preliminary study

Objectives

Lymphoceles are among the most common post-operative complications of pelvic lymphadenectomy, with a reported incidence of 1% to 29% in gynecology oncology. Several studies evaluated the effectiveness of biological glues on reducing lymphoceles, but no data on gynecological patients are available. We evaluated the effectiveness of cyanoacrylic glues (n-butyl cyanoacrylate) (Glubran 2 — GEM s.r.l., Italy) in preventing lymphocele on 30 patients who underwent pelvic lymphadenectomy for endometrial or cervical cancer.

Methods

Single-blind prospective randomized study. Patients were divided into 2 groups: pelvic lymphadenectomy plus n-butyl cyanoacrylate (treatment group: 44 patients) and pelvic lymphadenectomy without n-butyl cyanoacrylate (control group: 44 patients). Primary endpoint was incidence of pelvic lymphocele in the two groups 30 days after surgery, and evaluated with pelvic ultrasound and RMI examination. Secondary endpoints evaluated drainage volume of lymphorrhea 36, 48, 72 and 96 h after surgery.

Results

15% in the treatment group and 36.6% in the control group had lymphocele 1 month after the procedure (p < 0.03; RR 0.4 [95% CI 0.152–0.999]). Concerning the secondary outcome in group A the amount of lymphorrhea presented a constant significant decrease during evaluation; on the contrary, in group B, after an initial decrease at 48 h, the amount of lymphorrhea remained unchanged; at all considered times the amount of lymphorrhea resulted significantly greater in controls.

Conclusion

Intraoperative application of n-butyl cyanoacrylate seems to reduce lymph production after pelvic lymphadenectomy, providing a useful additional treatment option for reducing drainage volume and preventing lymphocele development after pelvic lymphadenectomy.     

Laparoscopic lymphadenectomy for gynecologic malignancies using ultrasonically activated shears: analysis of first 100 cases

OBJECTIVE: To evaluate the feasibility, safety and utility of the ultrasonic shears for laparoscopic pelvic and para-aortic lymph node retrieval in the treatment of gynecologic cancers. METHODS: Data on laparoscopic lymphadenectomy performed for gynecologic malignancies using ultrasonic shears over a 5-year period were collected and analyzed prospectively. RESULTS: Laparoscopic lymphadenectomy using ultrasonic shears was performed on 100 patients with a median age of 58 (17-87) years. The types of malignancies included cervical (n = 29), endometrial (n = 48), ovarian (n = 15), fallopian tube (n = 2), malignant mixed mesodermal tumor (n = 2), vaginal (n = 2) and synchronous ovarian and endometrial cancers (n = 2). Sites of lymphadenectomy included pelvic (n = 49), para-aortic (n = 30) or both pelvic and para-aortic (n = 21). The median nodal yield was 22 (0-87). 66/100 were complete lymphadenectomies with a median nodal yield of 28 (2-71). The median length of hospital stay was 2 (1-13) days and the average blood loss was 148 (0-500) ml. Overall complication rate was 13%. There were 3 intra-operative complications, which were all managed laparoscopically. There were no unplanned conversions to laparotomy. There were 10 post-operative complications including port-site metastasis in a patient with positive nodes (n = 1), trocar-site hernia requiring a second laparoscopy (n = 1), deep leg vein thrombosis (n = 1), and a small bowel obstruction (n = 1). CONCLUSIONS: This is the largest series to date demonstrating the safety and efficacy of ultrasonic shears in laparoscopic lymphadenectomy for gynecologic malignancies. In addition to the potential for lowering the risk for tissue damage, ultrasonic shears offer multifunctionality which allows for a simpler technique with the use of fewer instruments.     

Laparoscopic nerve-sparing radical vaginectomy in patients with vaginal carcinoma: surgical technique and operative outcomes

Study ObjectivesTo describe our technique for laparoscopic nerve-sparing radical vaginectomy and to assess the feasibility and safety of the procedure via operative outcomes.DesignRetrospective study (Canadian Task Force classification II-2).SettingMajor university teaching hospital in Chongqing, China.PatientsTwelve consecutive patients with early stage vaginal carcinoma.InterventionsLaparoscopic radical parametrectomy/vaginectomy with pelvic/paraaortic lymphadenectomy.Measurements and Main ResultsNerve-sparing radical vaginectomy was completed laparoscopically without conversion to laparotomy in 12 patients with early stage vaginal cancer. Mean (SD) operative time was 158.5 (36.7) minutes, and estimated blood loss was 135.2 (62.8) mL. No intraoperative complications occurred, and no patients required blood transfusion. The number of pelvic nodes obtained was 21.2 (9.8), and of para-aortic nodes was 13. All nodes were negative for malignancy. Histologic analysis confirmed the absence of any residual cancer tissue in the margins of the parametrial tissue and vagina. The median (range) time before Foley catheter removal was 9.76 (3–14) days, and bladder void function recovery to grade 0–I was observed in 11 patients (91.7%). Neither long-term bladder voiding dysfunction nor any other long-term complications were reported. The median duration of follow-up was 28 months. One patient with stage II vaginal cancer received pelvic regional radiation therapy; the other patients did not require adjuvant therapy after the operation. All patients were included in the follow-up protocol, and there was no recurrence of disease in any patients.ConclusionsLaparoscopic radical parametrectomy/vaginectomy with pelvic/para-aortic lymphadenectomy is a therapeutic option for early stage vaginal carcinoma. Nerve-sparing radical surgery in indicated patients may lead to optimal preservation of bladder function. The technique described in this preliminary study seems to be safe and feasible, and was relatively easy to perform in our study population.     

Robotic radical parametrectomy and pelvic lymphadenectomy in patients with invasive cervical cancer

ObjectiveWe describe a series of patients diagnosed with invasive cervical cancer after undergoing simple hysterectomy who subsequently underwent robotic radical parametrectomy and bilateral pelvic lymphadenectomy. The goal of this study is to report on the safety and feasibility of robotic radical parametrectomy.MethodsA retrospective review was performed of all patients who underwent robotic radical parametrectomy and bilateral pelvic lymphadenectomy at our institution during the period December 2006 to February 2008. We analyzed our data to evaluate the safety and feasibility of performing robotic radical parametrectomy.ResultsThis analysis included 5 patients with invasive squamous cell carcinoma of the cervix. The median body mass index was 23.8 kg/m² (range, 17.7 to 26.5). The median operative time was 365 min (range, 331 to 430). The median estimated blood loss was 100 mL (range, 50 to 175). There were no conversions to laparotomy. There was 1 intraoperative complication—cystotomy. No patient required blood transfusion. The median length of hospital stay was 1 day (range, 1 to 2). One patient experienced two postoperative complications, a vesicovaginal fistula and a lymphocyst. No patient had residual tumor in the parametrectomy specimen, and no patient underwent adjuvant therapy. The median number of pelvic lymph nodes removed was 14 (range, 6 to 16). The median follow-up for all patients was 7.5 months (range, 1.3 to 13.8). There were no recurrences.ConclusionRobotic radical parametrectomy and bilateral pelvic lymphadenectomy is feasible and safe and can be performed with an acceptable complication rate.     

Randomized Study Comparing Use of THUNDERBEAT Technology vs Standard Electrosurgery during Laparoscopic Radical Hysterectomy and Pelvic Lymphadenectomy for Gynecologic Cancer

Study ObjectiveTo compare operative time with use of THUNDERBEAT (TB) vs standard electrosurgery (SES) during laparoscopic radical hysterectomy and pelvic lymphadenectomy to treat gynecologic tumors.DesignEvidence obtained from a properly designed, randomized, controlled trial (Canadian Task Force classification I).SettingGynecologic Oncology Unit of the Catholic University of the Sacred Heart in Rome, Italy.PatientsFifty patients with early cervical cancer (FIGO stages IA2, IB1, IIA <2 cm) or locally advanced cervical cancer (FIGO stages IB2, IIA >2cm, IIB) who received neoadjuvant treatment (chemotherapy or radiochemotherapy) and demonstrated a complete or partial clinical response and early stage endometrioid endometrial cancer (FIGO stages IB, II) were randomly assigned to undergo TB (arm A) or SES (arm B).InterventionLaparoscopic radical hysterectomy with bilateral pelvic lymphadenectomy, using an easily reproducible technique was performed.Measurements and Main ResultsFifty patients were available for analysis, with 25 women randomly assigned to TB (arm A) and 25 to SES (arm B). The median operative time was 85 minutes for TB vs 115 minutes for SES (p = .001). At multivariate analysis, endometrial cancer (p = .001) and TB (p = .001) were independently associated with shorter operating time. No differences in perioperative outcomes and postoperative complications were observed between the 2 arms. Patients who underwent TB reported less postoperative pain, both at rest (p = .005) and after the Valsalva maneuver (p = .008), with less additional analgesic therapy other than standard therapy required in patients who underwent SES (p = .02).ConclusionTB is associated with shorter operative time and less postoperative pain than is the standard technique (SES) in patients with uterine cancer.     

Surgery without radiotherapy for primary treatment of endometrial cancer

Objective: To analyze the role of surgery alone, including pelvic and para-aortic lymphadenectomy, in patients with endometrial cancer who did not receive radiotherapy.Methods: Between August 1987 and January 1997, 225 women with disease clinically confined to the uterus were staged surgically by a standard protocol that included pelvic and para-aortic lymphadenectomy in women with high risk factors. No radiation was administered before or after surgery.Results: The combination of preoperative endometrial biopsy grade and gross depth of myometrial invasion identified 123 (55%) high-risk patients who had lymphadenectomy and 102 (45%) low-risk patients who did not. Eighteen (15%) high-risk patients had lymph node metastases and received postoperative systemic therapy. Three low-risk, eight high-risk-node-negative, and no high-risk-node-positive patients were diagnosed with recurrent cancer, corresponding to 5-year recurrence-free proportions of 0.95, 0.89, and 1.00, respectively. Although sample sizes and limited follow-up limit conclusions, the experience to date suggests a high rate of survival in all three groups.Conclusion: Our preliminary experience indicates that even high-risk patients have an excellent prognosis when treated with surgery, including pelvic and para-aortic lymphadenectomy, without radiotherapy.     

Surgical Treatment of Endometriosis in Private Practice: Cohort Study with Mean Follow-up of 3 Years

Study ObjectiveTo describe our experience with surgical treatment of endometriosis.DesignObservational cohort study (Canadian Task Force classification II-2).SettingPrivate hospital.PatientsOne hundred sixty-three patients with histologically confirmed endometriosis who had completed a preoperative questionnaire, had available intraoperative findings and photographic documentation, and had been followed up to 6 years.InterventionLaparoscopic electrosurgical excision of endometriotic implants.Measurements and Main ResultsPatients completed a visual analogue scale (VAS) for 6 components of endometriosis-related symptoms. The EuroQol Group EQ-5D questionnaire was used for evaluation of quality of life. Long-term follow up was performed using a questionnaire and review of patient medical records. Mean (SD; 95% confidence interval) patient age at surgery was 31.01 (8.5; 29.7–32.3) years. The primary symptom at initial consultation was dysmenorrhea in 94 patients (57.67%, nonmenstrual pelvic pain in 44 (27%), dyspareunia in 11 (6.75%), menorrhagia in 8 (4.9%), infertility in 4 (2.45%), and pelvic mass in 2 (1.23%). Thirty-three patients (20%) had undergone previous surgery because of endometriosis. At surgery, endometriosis was stage I in 50 patients (30.67%), stage II in 65 (39.88%), stage III in 23 (14.11%), and stage IV in 25 (15.34%). Other surgical procedures performed with the index surgery were cystoscopy in 48 patients (29.45%), laparoscopic ovarian cystectomy in 24 (14.72%), laparoscopic hysterectomy in 15 (9.2%), laparoscopic appendectomy in 9 (5.5%), sigmoidoscopy in 6 (3.68%), laparoscopic oophorectomy in 6 (3.68%), extensive laparoscopic adhesiolysis in 5 (3.07%) bowel resection in 2 (1.25%), laparoscopic myomectomy in 1 (0.61%), and bladder resection in 1 (0.61%). Surgery proceeded to laparotomy in 6 patients (3.68%). Major surgical complications included bowel perforation, severe pelvic pain 1 week after laparoscopic excision, and temporary numbness of the right side of the perineum in 1 patient each. Minor postoperative complications included urinary tract infection in 3 patients and port site infections that resolved with oral antibiotic therapy in 2 patients. Follow-up was 37.82 (20.09; 34.74–40.92) months. Surgical excision of endometriosis had a positive effect on endometriosis-related symptoms. Four pain scores were reduced, with statistically significant differences (p <.001 and p <.05): dysmenorrhea, pelvic pain not related to menstruation, dyspareunia, and dyschezia. The positive effect of surgical excision on patient quality of life was demonstrated by a statistically significant difference on the EQ-5D index (p <.001) and the EQ-5D VAS (p <.001). Thirty-two (20%) patients underwent a second procedure after the index surgery. Endometriosis stage affects the probability of requiring further surgery because of recurrent symptoms. There was evidence of endometriosis at histologic analysis in only 13 (40.62%) patients who required further surgery.ConclusionLaparoscopic excision of endometriosis significantly reduces pain and improves quality of life as measured by both the EQ-5D index and the EQ-5D VAS, with a low complication rate.     

Efficacy of systematic lymphadenectomy and adjuvant radiotherapy in node-positive endometrial cancer patients

OBJECTIVE: To assess the efficacy of systematic lymphadenectomy and adjuvant radiotherapy in minimizing pelvic sidewall and para-aortic failures. METHODS: Between January 1984 and December 2001, a total of 146 patients with stage III and IV endometrial cancer and lymph node metastases were treated at our institution. Adequate pelvic lymphadenectomy was defined as the removal of more than 10 pelvic lymph nodes, and adequate para-aortic lymphadenectomy was defined as removal of 5 or more para-aortic lymph nodes. The 24 patients who received adjuvant chemotherapy were excluded. We assessed the ability of adequate pelvic and para-aortic lymphadenectomy, together with radiotherapy, to prevent pelvic and para-aortic recurrences. RESULTS: Of the 122 patients studied, 94 (77%) had adequate pelvic lymphadenectomy and 47 (39%) had adequate para-aortic lymphadenectomy. Pelvic radiotherapy was administered to 78% and para-aortic radiotherapy to 29% of patients. Median follow-up of censored patients was 56 months. Twenty-five percent of patients had pelvic sidewall failure at 5 years. Pelvic sidewall failures at 5 years occurred in 57% of patients who had inadequate node dissection and/or no radiotherapy, compared with 10% for those having both adequate lymphadenectomy and radiotherapy (P < 0.001). After risk factor assessment in a regression model, only treatment with adequate lymphadenectomy and radiotherapy was a significant independent predictor of pelvic control (P = 0.03). The performance of definitive pelvic lymphadenectomy may have increased treatment-related morbidity in the subgroup of patients who had postoperative radiotherapy. For the 41 patients with positive para-aortic lymph nodes, the 5-year para-aortic failure rate was 34% after adequate lymphadenectomy but without adjuvant para-aortic radiotherapy. Likewise, 69% failed in the para-aortic area when adjuvant para-aortic radiotherapy was administered to patients not having adequate para-aortic lymphadenectomy; however, none of the 11 patients failed in the para-aortic area after adequate lymphadenectomy and para-aortic radiotherapy (P = 0.08). CONCLUSIONS: Adequate (pelvic and para-aortic) lymphadenectomy and adjuvant radiotherapy appear complementary in reducing failures in both the pelvis and para-aortic areas in patients with node-positive endometrial cancer.
