Lower incidence of inguinal hernia after radical prostatectomy using open gasless endoscopic single-site surgery

Inguinal hernia is one of the long-term complications requiring surgical interventions after retropubic radical prostatectomy (RRP), and its incidence has been reported to range from 12 to 21%. The number of open gasless laparoendoscopic single-site surgery, especially minimum incision endoscopic radical prostatectomy (MIES-RRP) is increasing in Japan. The incidence of post-operative inguinal hernia was compared between conventional RRP and MIES-RRP. The medical records of 333 patients who underwent conventional RRP (n=214) or MIES-RRP (n=119) with pelvic lymphadenectomy at our hospital were retrospectively evaluated. There were no significant differences between the two groups in age, pre-operative PSA levels, or previous major abdominal surgery (cholecystectomy, gastrectomy and colectomy), appendectomy or inguinal hernia repair. MIES-RRP was carried out with a 5-8-cm lower abdominal midline incision. Inguinal hernia developed postoperatively in 41 (19%) of the 214 men undergoing conventional RRP during mean follow-up of 58 months (range: 7-60 months). In contrast, 7 (5.9%) of the 119 men receiving MIES-RRP, developed inguinal hernia during mean follow-up of 21 months (range: 13-31 months). The hernia-free survival was significantly higher after MIES-RRP than after conventional RRP (P=0.037). Our results suggest that MIES-RRP is less associated with post-operative inguinal hernia than conventional RRP.     

Concurrent radical retropubic prostatectomy and inguinal hernia repair through a modified Pfannenstiel incision

OBJECTIVE: To describe a technique for concurrent radical retropubic prostatectomy (RRP) and inguinal hernioplasty, using a modified Pfannenstiel incision. PATIENTS AND METHODS: RRP is usually done through a midline lower abdominal incision but some patients with localized prostate cancer have an inguinal hernia. Concurrent inguinal hernia repair at the time of RRP with the usual method is only possible by either a preperitoneal mesh repair or formal hernioplasty, requiring an additional incision(s). A 10-12 cm Pfannenstiel incision is made along the pubic hairline centred over the pubic symphysis, and a 'Y'-shaped incision in the rectus sheath. The rectus muscle is split vertically along the midline, followed by RRP. After removing the prostate and completing the anastomosis, the surgeon identifies the inguinal canal along the inferior and lateral aspect of the transverse incision and uses a formal tension-free hernioplasty with a 3 x 5 cm polypropylene mesh. We used this technique in fifteen concurrent inguinal hernioplasties (two bilateral hernias and thirteen unilateral) at the time of RRP, with no additional incisions, using the formal tension-free Lichtenstein technique. One patient with bilateral hernias had a right indirect inguinal hernia, and all the remaining men had a direct inguinal hernia. RESULTS: All patients were discharged 2 days after surgery, with no complications associated with the procedure and no recurrences; however, the follow-up was short (mean 5.5 months). CONCLUSION: A modified Pfannenstiel incision is ideal for concurrent RRP and inguinal hernioplasty, providing excellent exposure of the pelvic structures and allowing the surgeon to use a formal tension-free mesh hernioplasty through the same incision. Wound healing and cosmetic results are excellent.     

Frequency of postoperative inguinal hernia after endoscope-assisted mini-laparotomy and conventional retropubic radical prostatectomies

Objective:   The objective of the present study was to compare the incidence of postoperative inguinal hernia between endoscope-assisted mini-laparotomy retropubic radical prostatectomy (mini-lap RRP) with conventional techniques to identify possible risk factors.
Methods:   From April 1998 to December 2006, 347 consecutive cases with localized prostate cancer were treated with conventional RRP (75 cases) and mini-lap RRP (272 cases) with pelvic lymphadenectomy. Mini-lap RRP was carried out with a 6-cm median incision. The charts were retrospectively reviewed, and the incidence of and risk factors for postoperative inguinal hernia were assessed.
Results:   There were no significant differences in age, initial prostate-specific antigen concentrations, clinical stage, Gleason score, body mass index, incidence of previous major abdominal surgery (cholecystectomy, gastrectomy, and colectomy), previous appendectomy, and previous inguinal hernia repair between the two groups. Postoperative inguinal hernia was observed in 29 cases (38.7%) in the conventional RRP group and in eight cases (2.9%) in the mini-RRP group during the mean follow-up period of 26.1 months (range: 3–105 months). The patients treated with mini-lap RRP had significantly higher hernia-free survival than those treated with conventional RRP (log rank test, P  < 0.001). Multivariate analysis showed that surgical technique (conventional RRP) and previous major abdominal surgery were risk factors for inguinal hernia ( P  < 0.001 and P  = 0.007, respectively).
Conclusions:   Inguinal hernia was less frequent after mini-lap RRP than after conventional RRP. A history of a major abdominal surgery was an independent risk factor for this event.     

Inguinal hernia after radical retropubic prostatectomy for prostate cancer: a study of incidence and risk factors in comparison to no operation and lymphadenectomy

PURPOSE: The incidence, mechanisms and risk factors of inguinal hernia after radical retropubic prostatectomy are sparsely elucidated in the literature. We determined the rate of inguinal hernia after radical retropubic prostatectomy and compared it to the incidence in patients with prostate cancer who did not undergo operation or underwent only pelvic lymph node dissection. MATERIALS AND METHODS: We followed 375, 184 and 65 men who underwent radical retropubic prostatectomy plus pelvic lymph node dissection, pelvic lymph node dissection only and no surgery with respect to inguinal hernia for a mean of 39, 47 and 45 months, respectively. The prostatectomy group was also evaluated in regard to the potential risk factors of previous hernia surgery and post-prostatectomy anastomotic stricture. RESULTS: The incidence of hernia was 13.6%, 7.6% and 3.1% in the prostatectomy, lymph node dissection and unoperated group, respectively. The difference was statistically significant in the prostatectomy and unoperated groups according to the Mantel-Cox log rank test and Cox proportional hazards rate. Previous hernial surgery and post-prostatectomy anastomotic stricture were more common in patients with an inguinal hernia after prostatectomy. CONCLUSIONS: The incidence of inguinal hernia is clearly increased in men who have undergone radical retropubic prostatectomy plus pelvic lymph node dissection compared with those who undergo no surgery for prostate cancer. Inguinal hernia appears to develop more often in men with prostate cancer who undergo radical retropubic prostatectomy and pelvic lymph node dissection than in those who undergo pelvic lymph node dissection only. While surgical factors trigger hernial development, previous hernial surgery and post-prostatectomy anastomotic stricture may be important risk factors. In fact, the latter may largely explain the difference in the incidence of inguinal hernia in our lymph node dissection and prostatectomy groups. Prophylactic surgical procedures must be evaluated to address this problem.     

Post-radical retropubic prostatectomy inguinal hernia: an analysis of risk factors with special reference to preoperative inguinal hernia morbidity and pelvic lymph node dissection

PURPOSE: Inguinal hernia after radical retropubic prostatectomy has been reported to occur in 7% to 21% of patients. We analyzed the impact of simultaneous pelvic lymph node dissection, preoperative inguinal hernia morbidity, postoperative anastomotic stricture, duration of surgery and patient age. We also compared the detection rate of inguinal hernia events in a retrospective patient file survey to that in a prospective patient administered questionnaire. MATERIALS AND METHODS: A total of 498 patients underwent radical retropubic prostatectomy plus pelvic lymph node dissection and 166 underwent radical retropubic prostatectomy only. Mean followup was 40 months (median 37, range 3 to 85). All 664 patients were analyzed in the patient file survey. The patient administered questionnaire was mailed preoperatively, and after 3, 6, 12, 18, 24 and 36 months to 271 patients who underwent operation between 2001 and 2002. A total of 207 patients (76.4%) completed the preoperative questionnaire. RESULTS: The cumulative incidence of inguinal hernia after 24 months was 11.6% in the patient file survey and 15.7% in the patient administered questionnaire. In the patient file survey patient age was the only studied factor that significantly influenced risk. The patient file survey failed to detect half of the men with preoperative inguinal hernia morbidity and a third of post-radical retropubic prostatectomy inguinal hernias compared to the patient administered questionnaire. On patient administered questionnaire analysis preoperative inguinal hernia morbidity was a significant risk factor for postoperative inguinal hernia (log rank Mantel-Cox test p = 0.010). CONCLUSIONS: Previous inguinal hernia morbidity and age increase the risk of post-radical retropubic prostatectomy inguinal hernia. Simultaneous pelvic lymph node dissection, postoperative anastomotic stricture and duration of surgery were not significant risk factors in this study. The patient file survey is inferior to the patient administered questionnaire for detecting inguinal hernia events.     

Lower incidence of inguinal hernia: minilaparotomy radical retropubic prostatectomy compared with conventional technique. A preliminary report

INTRODUCTION: The purpose of the present study was to compare the incidence of inguinal hernias after conventional and minilaparotomy (minilap) radical retropubic prostatectomy (RRP). PATIENTS AND METHODS: In this retrospective study, we review our experience with 70 consecutive patients with prostate cancer who underwent prostatectomy from April 1995 through March 2001. Of these, 35 patients had conventional RRP, and 35 patients had minilap RRP. RESULTS: Conventional RRP and minilap RRP groups were similar in body mass index (mean 24.4 and 23.5), operative time (mean 260 and 241 min), previous lower abdominal operation record (mean 37.1 and 25.7%), and post-prostatectomy anastomotic strictures (mean 11.4 and 14.3%). The volume of the estimated blood loss was significantly less for minilap RRP (mean 1,220 ml) than for conventional RRP (mean 1,666 ml; p = 0.0194). The incidence of postoperative inguinal hernias was 17.1% (6 of 35), 2.9% (1 of 35), and 3.2% (1 of 31) in conventional RRP, minilap RRP, and unoperated groups, respectively. The incidence of inguinal hernias after minilap RRP was significantly lower than after conventional RRP (p = 0.0464). Seven patients with postoperative inguinal hernias had a high incidence of postoperative strictures (42.9%), while 63 patients without hernia had a low incidence (9.5%). There was a significant difference in developing postoperative strictures between patients with hernia and those without (p = 0.0124). While postoperative stricture and operative technique were different in the hernia and hernia-free groups on univariate analysis, multivariate logistic analysis revealed that the operative technique was an independent factor for the occurrence of inguinal hernias (p = 0.0419). CONCLUSION: Minilap RRP compares favorably with conventional RRP in view of the postoperative inguinal hernia development.     

Patent processus vaginalis in adults who underwent robot‐assisted laparoscopic radical prostatectomy: Predictive signs of postoperative inguinal hernia in the internal inguinal floor

Objective: To evaluate the risk for postoperative inguinal hernia according to the presence of patent processus vaginalis in an adult population. Methods: Medical records of 205 patients who underwent robot‐assisted laparoscopic radical prostatectomy from May 2007 to November 2011 were reviewed. Age, prostate‐specific antigen, prostate volume, body mass index, operative time and history of previous abdominal surgery were evaluated. The existence of patent processus vaginalis was also evaluated for the development of postoperative inguinal hernia. Results: Postoperative inguinal hernia occurred in 20 out of 410 (4.9%) groins (17/205 patients; 8.3%), and patent processus vaginalis was observed in 49 out of 410 (11.9%) groins. In the normal groin group, inguinal hernia occurred in seven out of 361 (1.9%) groins. However, in the patent processus vaginalis group, it occurred in 13 out of 49 (26.5%) groins. On univariate analysis using Cox proportional hazards model, age, body mass index, history of previous abdominal surgery and patent processus vaginalis were significant risk factors. Among them, patent processus vaginalis significantly increased the risk of postoperative inguinal hernia in multivariate analysis (hazard ratio 22.37). In the patent processus vaginalis group, inguinal hernia developed at 12.9 ± 9.2 months after robot‐assisted laparoscopic radical prostatectomy and 15 ± 7.4 months in the normal groin group. Inguinal hernia‐free ratios were significantly lower in the patent processus vaginalis group than the normal groin group (P < 0.001). Conclusions: The existence of patent processus vaginalis represents an important risk factor for postoperative inguinal hernia in adults. Urologists should consider the possibility of postoperative inguinal hernia when patent processus vaginalis is observed during surgery.     

Incidence of inguinal hernia after prostate surgery: Open radical retropubic prostatectomy versus open simple prostatectomy versus transurethral resection of the prostate

Our objective was to determine the incidence of inguinal hernia (IH) after surgery for prostatic diseases. Medical records of 395 patients who underwent radical retropubic prostatectomy (RRP; n  = 155), open simple prostatectomy (OP; n  = 35), or transurethral resection of the prostate (TURP; n  = 205) at the Chibaken Saiseikai Narashino Hospital from April 2000 to March 2007 were retrospectively evaluated. The incidence of IH was 23.9% in the RRP group, 18.9% in the OP group, and 2% in the TURP group. Overall, 91.9% in the RRP and 83.3% in the OP group developed an IH within 2 years postoperatively. The laterality of IH after open surgery was mainly on the right side. Subclinical IH were seen in 25% of RRP cases. The existence of subclinical IH was the only significant risk factor for postoperative IH in this analysis. Furthermore, OP and RRP procedures significantly increased the risk of postoperative IH compared with TURP. The hernia-free ratios were significantly lower after RRP and OP than after TURP ( vs RRP: P  < 0.001; vs OP: P  < 0.001). Our findings confirm that a lower abdominal incision itself is associated with postoperative IH in patients undergoing prostate surgery. Attention must be paid to pre-existing subclinical IH through careful preoperative assessment. Patients should be followed for more than 2 years due to the high incidence of postoperative IH.     

Concurrent radical retropubic prostatectomy and Lichtenstein inguinal hernia repair through a single modified Pfannenstiel incision: a 3-year experience

OBJECTIVE: To present the results of a 3-year experience of radical retropubic prostatectomy (RRP) through a modified Pfannenstiel incision and concomitant repair of an inguinal hernia at the time of RRP, using a tension-free technique with a mesh, as described by Lichtenstein, with no additional incision(s), as 5-10% of patients with clinically localized prostate cancer have a detectable inguinal hernia. PATIENTS AND METHODS: Patients who had RRP between October 2002 and July 2005 were included; we used a standard open RRP, in all cases using a modified Pfannenstiel incision. If the patient had an inguinal hernia, we approached the inguinal canal through the same incision and performed a Lichtenstein mesh repair, through the inguinal canal and avoiding placing mesh within the pelvis. Patients were followed at 1 and 6 weeks, 3-monthly for 1 year and 6-monthly thereafter. All clinical variables were entered into a database and analysed. RESULTS: In all, 450 men underwent RRP; 44 (10%) had inguinal hernia and in all, 56 hernias were repaired (32 unilateral and 12 bilateral; 16 indirect, 22 direct, six both) The mean (sd) age of the patients was 60 (7) years. Most patients were discharged within 36 h. The mean (sd) follow-up was 9 (8) months. Two patients had a superficial inguinal haematoma and one had a scrotal haematoma. They were treated conservatively with no sequelae. There were no wound infections. One patient developed a recurrent inguinal hernia. None had any clinical evidence of testicular atrophy or chronic pain. CONCLUSION: Concurrent formal mesh repair of the inguinal hernia and RRP through a single modified Pfannenstiel incision is safe and effective. The complications were minimal and recurrence rates were low. This procedure eliminates the risks involved with the preperitoneal mesh repair and avoids multiple incisions.     

Transperitoneal robotic-assisted laparoscopic radical prostatectomy and inguinal herniorrhaphy

Patients undergoing radical prostatectomy are at increased risk of development of post-operative inguinal hernias (IH). We present the largest series of transperitoneal combined robotic-assisted laparoscopic prostatectomy (RALP) and IH. After IRB approval, data from patients undergoing RALP at two centers were prospectively entered into a database and analyzed. IH were repaired robotically via a transperitoneal route with mesh. Between June 2002 and May 2007, 837 RALPs were performed, 80 of which included combined IH repair (9.6%), by two surgeons, T.A. and D.S. Forty-two patients (52.5%) had IH on pre-operative exam. Twenty-four hernias were left, 32 right, and 24 bilateral. Twenty-two patients had prior ipsilateral or contralateral herniorrhaphy. After dissection of the hernia sac, a swatch of flat Marlex mesh (n = 22), a polypropylene mesh plug (n = 19), an Ultrapro hernia system (n = 7), a Proceed coated mesh (n = 19), a 3D-Max (n = 37), a combination of both umbrella and flat mesh (n = 3), or suture alone (n = 2) was used. Inguinal herniorrhaphy added approximately 15 min of operative time in all cases. There was one hernia recurrence over an average follow-up period of 12.5 months (0.2–52 months). There was one complication attributable to IH repair—a urine leak which was attributed to anastomotic stretch due to reperitonealization. Urological surgeons should perform a thorough inguinal exam during preoperative evaluation and intraoperatively to detect subclinical inguinal hernias. Inguinal herniorrhaphy at the time of RALP is safe and should be routinely performed.     

Prognostic factors of postoperative morbidity and mortality in strangulated groin hernia

Objective

Strangulated groin hernia is a serious surgical emergency, as it is associated with high morbidity and mortality (2.6–9?%). This retrospective study aimed to find significant prognostic factors of postoperative morbidity and mortality.

Methods

From January 2000 to August 2011, we analyzed all patients who had undergone surgery in emergency for strangulated groin hernia. Forty-nine patients out of 2,917 were operated on strangulated groin hernia in an emergency.

Results

The occurrence of strangulated hernia during this period was 1.7?%. Thirty patients out of 49 had inguinal (61.2?%) and 19 femoral (38.8?%) strangulated hernias. The median age was 68.9?years?±?15.3. Patients with strangulated femoral hernia were significantly older than those with inguinal hernia (P?=?0.03). There was a significant predominance of men in the inguinal hernia group and a female predominance in the femoral hernia group (P?=?0.001). An additional exploration was performed on 12 patients (24.5?%). This exploration was done through a midline laparotomy in 8 patients, a laparoscopy in a single patient and the hernioscopy technique was beneficial in exploring the peritoneal cavity in 3 patients. Intestinal resection was necessary in 10.2?%. In our experience, 50?% of midline laparotomies were performed without any intestinal resection. Fisher’s test identified midline laparotomy as the only prognostic factor of postoperative morbidity.

Conclusion

First intention exploratory laparotomy in strangulated hernia surgery was, in our study, a major cause of postoperative complication.     

Complications after radical retropubic prostatectomy in the medicare population

OBJECTIVES: Radical prostatectomy is the standard of care for the treatment of clinically localized prostate cancer in the appropriate patient. However, the morbidity associated with this procedure remains controversial, since complications from centers of excellence are low but nationwide surveys have reported a much higher risk of complications. This study reports the complication rates after radical retropubic prostatectomy (RRP) for men in the Medicare population. METHODS: All men in the Medicare population who underwent RRP in 1991 were identified. All inpatient, outpatient, and physician (Part B) Medicare claims for these men for 1991 to 1993 were then analyzed to determine outcomes. Procedures performed for complications resulting from RRP were recorded, as were the diagnosis codes that may have heralded a complication after RRP. RESULTS: In 1991, 25,651 men in the Medicare population underwent RRP. The mean age of these men was 70.5 years. Procedures for the relief of bladder outlet obstruction or urethral strictures after RRP occurred in 19.5% of these men. A penile prosthesis was implanted in 718 men (2.8%) after prostatectomy, and 593 men (2.3%) had an artificial urinary sphincter placed after prostatectomy. A diagnosis of urinary incontinence was reported in 5573 men (21.7%) after radical prostatectomy, but only 2025 of these men (7.9%) continued to carry this diagnosis more than 1 year after prostatectomy. A diagnosis of erectile dysfunction was reported in 5510 men (21.5%) after radical prostatectomy, but only 3276 of these men (12.8%) continued to carry this diagnosis more than 1 year after surgery. CONCLUSIONS: A review of a large, nationwide, heterogenous cohort of men revealed a morbidity rate that is slightly higher than that reported by major centers that perform large numbers of radical retropubic prostatectomies but is lower than complication rates obtained by patient surveys. The limitations of claim information in determining patient outcomes, however, must be considered when evaluating these data.     

Inguinal hernia repair with the mesh plug method is safe after radical retropubic prostatectomy

Purpose

We evaluated the safety and efficiency of using the mesh plug method (MP) to repair inguinal hernias in patients with a history of radical retropubic prostatectomy (RRP). We also investigated how RRP influences the development of inguinal hernias and impacts their repair.

Methods

Among 488 adult male patients who underwent inguinal hernia repair during a recent 5-year period, 37 had a history of RRP. We compared the characteristics and surgical outcomes of the patients who had undergone RRP (post-RRP group) with those who had not (non-RRP group).

Results

All post-RRP hernias were treated by MP. The 37 post-RRP patients had a collective 41 hernias, 40 of which were of the indirect type. The side affected by the hernia did not differ significantly between the groups. We compared the short-term surgical outcomes of the indirect post-RRP hernias vs. the indirect non-RPP hernias without recurrence and incarceration. The operation times, postoperative hospital stay, and mobility rates did not differ significantly between the two groups. The blood loss was almost equal in both groups.

Conclusion

Inguinal hernia repair after RRP may be difficult because of inflammatory changes in the preperitoneal cavity, but the surgical outcomes of MP were equivalent in patients with or without a history of RPP in this study. MP is a safe and effective method for post-RPP hernia repair.     

Inseparable interaction of the prostate and inguinal hernia

With an increase in their prevalence, it has become apparent that both benign prostatic hyperplasia and radical prostatectomy for cancer can induce inguinal hernia development. An inguinal hernia is a common late complication following radical prostatectomy, with an occurrence rate of 12–25%. Following radical prostatectomy, the space of Retzius can develop adhesions to surrounding tissue, often causing difficulty during inguinal hernia repair. Conversely, inguinal hernia repair before radical prostatectomy also induces severe adhesions around the space of Retzius and causes difficulty during radical prostatectomy. The association between radical prostatectomy and inguinal hernia development is complex and unclear. Both urologists and surgeons are challenged by this interaction. The surgical approaches for prostate cancer have undergone a major transition from open surgery to robotic surgery, and the treatment of inguinal hernia is also changing. Based on historical trends, several preventive and treatment measures have been proposed, although there is no direct evidence for risk factors that lead to inguinal hernia development. This article focuses on the complex interaction between the prostate and inguinal hernia, and considers preventive measures against inguinal hernia development.     

Combined retropubic prostatectomy and preperitoneal inguinal herniorrhaphy

Inguinal hernia and an enlarged prostate causing urinary obstruction are 2 disorders with a higher frequency among elderly patients. The anatomical proximity of an inguinal hernia to the enlarged prostate raises the possibility of joint, concurrent surgical treatment of both disorders. We report on the successful preperitoneal repair via a Pfannenstiel incision of 131 inguinal hernias in 97 patients who had undergone retropubic prostatectomy owing to benign enlargement of the prostate. Followup averaged 7 years and included 91 patients with 122 direct and indirect, unilateral or bilateral hernias. Summation of our results shows a low recurrence rate (4.9 per cent) and no complications in the wake of the combined operation. In our opinion prostatectomy combined concurrently with inguinal hernia repair via a preperitoneal retropubic approach should be applied routinely in urological practice.     

La relación entre hernia inguinal y cirugía mínimamente invasiva para el cáncer de próstata: revisión sistemática de la literatura

ObjectiveWe aimed to perform a systematic review about the relationship between inguinal hernia and surgery for prostate cancer.BackgroundDiagnosis of abdominal wall defects and prostate cancer may be either synchronous or metachronous. The convenience and safety of combined prostatectomy and hernioplasty, the incidence of hernias after prostatectomy and the feasibility of prostatectomy in patients with previous laparoscopic hernioplasty are still debated.MethodsPubMed and Embase were queried by dedicated search strings. Two researchers independently reviewed the pooled references and selected the articles of interest, including reviews.ResultsSixty-five studies were evaluated, 22 of them analysed the feasibility and the outcomes of a combined surgery, namely one-stage radical prostatectomy and herniorrhaphy or hernioplasty. Literature evidences support the combined intervention to patients suffering from an inguinal hernia and a prostate cancer amenable of radical prostatectomy. Sixteen studies addressing the potential increase in the occurrence of inguinal hernia after radical prostatectomy were evaluated. Approximately 15% of patients who undergo retro-pubic radical prostatectomy will develop inguinal hernia. It is suggested that the incidence might be lower in laparoscopic prostatectomy series, particularly in case of transperitoneal approach. The median time to the appearance of the hernia is around 6 months. After evaluation of 14 studies, it is concluded that laparoscopic hernioplasty does not preclude prostatectomy but hinders further pelvic surgery.ConclusionsOne-stage combined hernioplasty and radical prostatectomy may be accepted except in cases of lymph-nodes dissection and/or positive hydro-distress test of the urethro-vesical anastomosis. Accurate patient's counselling and dedicated consent form are mandatory, in the setting of an experienced multidisciplinary team.     

Incision and abdominal wall hernias in patients with aneurysm or occlusive aortic disease

INTRODUCTION: Patients undergoing midline incision for abdominal aortic reconstruction appear to be at greater risk for postoperative incision hernia compared with patients undergoing celiotomy for general surgical procedures. Controversy exists as to whether incidence of abdominal wall hernia and increased risk for incision hernia is higher in patients with abdominal aortic aneurysm (AAA) than in patients operated on because of aortoiliac occlusive disease (AOD). We conducted a prospective multi-institutional study to assess frequency of incision hernia after aortic surgery through a midline laparotomy and of previous abdominal wall hernia. METHODS: Patients with AAA (n = 177) or AOD (n = 82) from three major institutions were prospectively enrolled in the study and examined. Data collected included demographic data, cardiopulmonary risk factors, smoking status, history of previous or current abdominal wall hernia (incision, inguinal, umbilical, femoral), previous midline incision, suture type, and postoperative complications. At a minimum of 6 months after laparotomy, patients were evaluated clinically for a new incision hernia. Differences were tested with the unpaired t test, X(2) test, or Fisher exact test, and multiple logistic regression was used to control for confounding variables. RESULTS: Mean follow-up of the cohort was 32.8 +/- 2.3 months. Rate of abdominal wall hernia and inguinal hernia in patients with AAA versus AOD was 38.4% versus 11% (P =.001) and 23.7% versus 6.1% (P =.003), respectively. Rate of postoperative incision hernia in patients with AAA was 28.2%, and in patients with AOD was 11.0% (P =.002). Adjusting for age, smoking, chronic obstructive pulmonary disease, body mass index, diabetes, bowel obstruction, and suture type, patients with AAA had almost a ninefold risk for postoperative incision hernia formation (odds ratio [OR], 8.8; P =.0049). CONCLUSION: Compared with patients with AOD, patients with AAA have a higher frequency of abdominal wall hernia and inguinal hernia, and are at significant increased risk for development of incision hernia postoperatively. The higher frequency of hernia formation in patients with AAA suggests the presence of a structural defect within the fascia. Further studies are needed to delineate the molecular changes of the aorta and its relation to the abdominal wall fascia.     

Die radikale Prostatektomie beim klinisch lokalisierten Prostatakarzinom Kontra laparoskopischer Zugangsweg

Laparoscopic radical prostatectomy (LRP) offers an alternative to open prostatectomy in the treatment of clinically localized prostate cancer. However, when considering this new approach, oncological and functional results must be comparable to those of open retropublic prostatectomy (RRP). Long-term follow-up data for LRP are still lacking. RRP shows biochemical-free survival rates of 80% after 5 and 10 years. When evaluating functional results, data for postoperative erectile function after LRP are unclear. The functional data of postoperative continence after LRP seemed to be comparable to those of RRP. Even when considering aspects of morbidity and economy, RRP remains the golden standard in the treatment of clinically localized prostate cancer. Oncological and functional results are still preliminary for LRP.     

Anatomic radical retropubic prostatectomy—long-term recurrence-free survival rates for localized prostate cancer

Radical prostatectomy remains the mainstay for the treatment of localized prostate cancer. Long-term follow-up data showed excellent cancer control rates in several prostatectomy series. We report biochemical recurrence (BCR) outcomes after radical retropubic prostatectomy (RRP) in a European single center series of patients treated over a 13-year period. Between 1992 and 06/2005, 4,277 consecutive men underwent a RRP at the University Hospital Hamburg Eppendorf, Germany. Kaplan-Meier probabilities of BCR-free survival were determined for those patients with complete preoperative data, postoperative data, and follow-up information. Uni-and multivariate Cox regression models addressed PSA recurrence, defined as a PSA level ≥0.1 ng/ml. Overall, BCR-free survival ranged between 84, 70 and 61% for 2, 5, and 8 years, respectively. In univariate and multivariate analyses, except for age and type of nerve-sparing technique, all traditional clinical and pathological variables represented statistically independent predictors of PSA recurrence-free survival (all P≤0.001). In organ-confined disease, the 10-year recurrence free survival rate was 80 and 30% in non-organ-confined cancers. Our findings confirm excellent long-term biochemical cancer-control outcomes after RRP. High grade prostate cancer at final pathology and seminal vesicle invasion proved to be the strongest risk factors of BCR after surgery.     

Transabdominal preperitoneal robotic inguinal hernia repair

Inguinal hernias are commonly encountered at the time of radical retropubic prostatectomy. Concurrent inguinal hernia repair and prostatectomy is well described for the open and traditional laparoscopic approach. Robotic prostatectomy is the fastest growing treatment of prostate cancer. Concurrent robotic prostatectomy and robotic inguinal hernia repair has not been previously described. We recently performed such a procedure and describe our technique and impressions of this approach in this paper. The robotic surgical system allowed for the secure and efficient closure of the large transabdominal peritoneal flap following the preperitoneal placement of the mesh prosthesis. The robotic operating console provides the surgeon with a more comfortable, ergonomic position than is possible in a traditional laparoscopic approach. Robotic inguinal hernia repair is feasible immediately following robotic prostatectomy and may have certain advantages over alternative techniques.
