Extraperitoneal laparoscopic radical prostatectomy

A total of 28 patients with clinically localized prostate cancer (PCa) underwent extraperitoneal laparoscopic radical prostatectomy (EP-LRP). The mean operative duration was 309 (287-600) minutes. Estimated blood loss ranged from 380 to 1000 (mean 480) ml. At 3 to 5 days postoperatively, the catheter was removed. No open conversion was required and no patient presented postoperative complications. PSA level was less than 0.1 ng/ml at 3 months after surgery in all patients. At a mean follow-up of 10 (6-16) months, there were no biochemical failures. The extraperitoneal technique potentially decreased the risk of intra-abdominal complications and better approximated than open retropubic radical prostatectomy. In conclusion, EP-LRP is an effective, safe and precise technique.

Extraperitoneal standard laparoscopic radical prostatectomy

PURPOSE: To describe our preliminary experience with the extraperitoneal approach for laparoscopic radical prostatectomy. PATIENTS AND METHODS: Between February and December 2002, we performed 100 laparoscopic radical prostatectomies by an extraperitoneal approach. RESULTS: Of the procedures, 98 were completed as planned, while conversion to a transperitoneal approach was necessary in 2 patients with previous mesh hernia repair. The mean operative time was 163 minutes. The mean operative blood loss was 375 mL. The transfusion rate was 3%. No rectal, bowel, ureteral, or nervous injury was observed. There were no major complications. There were nine minor complications (four anastomotic leakages, one rectus muscle hematoma, four cases of acute urinary retention). The mean hospital stay was 6.1 days. Mean catheterization lasted 6 days. The pathologic stage was T2a, T2b, T2c, T3a, and T3b in 17%, 22%, 39%, 12%, and 10%, respectively. The mean Gleason score was 7. The margins were positive in 15% of the pT2 and in 35% of the pT3 tumors; 48% of the positive margins occurred in the first 25 cases. The median follow-up was 12 months; 93% of the patients had a serum prostate specific antigen concentration <0.2 ng/mL. No patient has presented with clinical port-site metastasis. All the patients were evaluated by questionnaire sent by mail before and after the surgery. With a median follow-up of 12 months, 86% of the patients were continent (no pads), 7% of the patients used 1 precaution pad, and 7% had need for 1 pad routinely. With a median follow-up of 6 months, among the preoperatively potent patients (IIEF5 >20), the postoperative erection and intercourse rate was 64% and 43% in patients with bilateral and unilateral nerve-bundle preservation, respectively. CONCLUSION: The extraperitoneal technique is a reliable approach for laparoscopic radical prostatectomy. The choice between a transperitoneal or an extraperitoneal approach depends on the surgeon's experience.     

Extraperitoneal robot-assisted laparoscopic radical prostatectomy: a single-center experience beyond the learning curve

Objectives

To report our surgical technique and outcomes after extraperitoneal robot-assisted laparoscopic radical prostatectomy (RALRP).

Materials and methods

At Henri Mondor’s Hospital, we performed the first RALRP in 2001 and started to perform routinely RALRP since 2006. Preoperative characteristics, perioperative parameters, functional and oncological outcomes were collected in a prospective database and studied. All parameters were tested in patients undergoing RALRP beyond the learning curve of each surgeon. The overall cohort included 792 patients.

Results

RALRP offers interesting results in terms of hospital stay, operative time, and blood loss. The overall rate of complications was low, especially concerning the rates of anastomosis’ complications. An extraprostatic extension was seen in 42.8 % of specimens. The overall rate of positive margins was 30.7 % of specimens. In our cohort, after a mean follow-up of 19 months, 8.7 % of PSA failure has been reported. The rate of continence was 77.4 % at 6 months and 96.8 % at 2 years. The rate of potency was 17 % at 3 months and 60.9 % at 2 years. The 2-year rate was 86.7 % in case of intrafascial dissection. A trifecta outcome was achieved in 44 and 53 % of men at 12 and 24 months, respectively.

Conclusions

The extraperitoneal approach confers interesting results in terms of perioperative parameters as previously described in series using a transperitoneal approach. Functional outcomes in terms of continence and potency recovery after extraperitoneal seem equivalent to those reported after transperitoneal RALRP. Longer follow-up is warranted to confirm our favorable mid-term oncologic outcomes.     

Extraperitoneal laparo-endoscopic single-site radical prostatectomy: first experience

Objectives

Up to now, laparo-endoscopic single-site surgery (LESS) represents the closest surgical technique to scar-free surgery. The objective of the study is to report the first clinical experience with a LESS endoscopic extraperitoneal radical prostatectomy.

Materials and methods

A 74-year-old man presented with a clinically localized prostate cancer (PSA 9.9, Gleason score 3 + 3 = 6). Consent was obtained for LESS radical prostatectomy. After a 2-cm midline subumbilical incision, the preperitoneal space was created using a balloon trocar. Then, the Triport? was introduced. Using straight, as well as pre-curved instruments, the radical prostatectomy was performed in accordance with the well-described technique of endoscopic extraperitoneal radical prostatectomy.

Results

The procedure was completed successfully. Overall operation time was 290 min. The estimated blood loss was 100 mL. There were no intra-or postoperative complications. No additional ports were required. On the 6th postoperative day, a cystogram was performed. No leak was demonstrated, enabling catheter removal. Histopathology revealed bilateral adenocarcinoma with no extracapsular extension and a Gleason sum of 3 + 4 = 7. Surgical margins were negative. Two weeks postoperatively, the patient reported the use of only one safety pad for continence.

Conclusions

An extraperitoneal laparo-endoscopic single-site radical prostatectomy is technically challenging but can be accomplished. A multi-instrument port and purpose-built equipment are mandatory. The oncologic outcome was not compromised. Additional short- and long-term studies are necessary to clarify the role of LESS in radical prostatectomy regarding the oncologic and functional outcome as well as the potential benefits like reduced tissue trauma and pain.

Extraperitoneal laparoscopic radical prostatectomy. Results after 50 cases

INTRODUCTION: After an initial experience using transperitoneal laparoscopic radical prostatectomy as described by Vallancien and Guillonneau, we developed a pure extraperitoneal approach. This approach seems more comparable to the open technique and avoid potential risks of specific complications due to the transperitoneal approach. We evaluated the perioperative parameters (blood loss, operating time, transfusion rate) and postoperative results (oncological results, continence and potency) after our first 50 cases. MATERIAL AND METHOD: Between September 1999 and September 2000, we performed 50 laparoscopic radical prostatectomy. On average, patients were 63.3 years old (range 47-71), had preoperative mean PSA values of 9.14 ng/ml (1.1-23). Median Gleason score was 6 (4-10) with 2.5 (1-6) positive biopsies for a mean prostate volume of 40 cm(3) (17.5-95.0). Clinical stage was T1, T2a, T2b and T3 in 46.3, 41.5, 9.8 and 2.4% of the cases, respectively. We used a pure extraperitoneal approach and we performed a descending technique starting with the dissection at the bladder neck. The seminal vesicles dissection is comparable to the open approach. RESULTS: 42 extraperitoneal and 8 transperitoneal procedures were performed (2 in the initial experience, 3 because of previous abdominal surgery and 3 because of incidental peritoneal opening). Mean operative time was 317 min, mean blood loss 680 cm(3), transfusion rate of 13%. 1 patient/50 was converted to an open procedure. Pathological stage was pT1a, pT2a, pT2b, pT2c, pT3a and pT3b in 2.2, 8.5, 42.5, 2.2, 34 and 10.6% of cases, respectively. Positive surgical margins were observed in 22% of cases. The potency rate after neurovascular bilateral bundle preservation was 43% at 3 months (n = 7) and 67% at 6 months and (n = 6) without any further treatment. The continence rate (no pad) was 39% at 3 months and 85% at 6 months. Detectable postoperative PSA at 3 month was observed in 2 patients only. Two major complications occurred: one acute transient renal failure one uretrorectal fistula at day 20. CONCLUSIONS: The extraperitoneal laparoscopic radical prostatectomy results seem comparable to transperitoneal laparoscopic radical prostatectomy or open surgery. This approach is reproducible and seems to avoid the potential risks of intraperitoneal injury. Long-term follow up and comparative series are however necessary to further evaluate these new techniques.     

Extraperitoneal laparoscopic radical prostatectomy: a prospective evaluation of 600 cases

PURPOSE: We report our experience with the extraperitoneal approach to laparoscopic radical prostatectomy. We describe the technique, clinical and oncological results, and functional outcome. MATERIALS AND METHODS: From February 2002, to March 2004, 600 laparoscopic radical prostatectomies were performed by an extraperitoneal approach and evaluated prospectively. RESULTS: A total of 599 extraperitoneal procedures were performed successfully. Mean operative time was 173 minutes. Mean operative blood loss was 380 cc. The transfusion rate was 1.2%. The major and minor complications rate was 2.3% and 9.2%, respectively. The reoperation rate was 1.7%. Mean hospital stay was 6.3 days. Pathological stage was pT2 and pT3 in 72% and 28% of cases, respectively. Mean Gleason score was 7. The overall positive margin rate was 17.7% (14.6% and 25.6% of pT2 and pT3 tumors, respectively). Median followup was 12 months. Of the patients 95% had prostate specific antigen less than 0.2 ng/ml. Patients were evaluated by a self-questionnaire sent by mail before and after surgery (International Continence Society and International Index of Erectile Function-5). At a median followup of 12 months 84% of the patients were continent (no pad), 7% used 1 precautionary pad and 7% needed 1 pad routinely. At a median followup of 6 months in preoperatively potent patients (International Index of Erectile Function-5 greater than 20) the postoperative erection and intercourse rate was 64% and 43%, respectively, in those with bilateral nerve bundle preservation. CONCLUSIONS: The extraperitoneal technique is a reliable approach to laparoscopic radical prostatectomy.     

Morbidity of laparoscopic radical prostatectomy: Summary of early multi-institutional experience in Japan

AIM: Laparoscopic radical prostatectomy is being evaluated throughout the world. The aim of the present study is to report early multi-institutional experience of the procedure in Japan. METHODS: A total of 148 men who were diagnosed with clinically localized prostate cancer underwent laparoscopic radical prostatectomy at seven different institutions in Japan. Early complications (within 30 days postoperatively) and postoperative convalescence were reviewed retrospectively. The median age of patients was 68.0 years (range, 51-80). RESULTS: The median operative time was 403 minutes (range, 167-925; average, 427). Blood loss ranged from 50 to 5000 mL (median, 540; average, 856). A total of 66 complications were reported in 55 patients (37.2%). Intraoperative complications were noted in 25 of 148 patients (16.9%): 10 rectal injuries (6.8%); five bladder injuries (3.4%); five cases of subcutaneous emphysema (3.4%); two intestinal injuries (1.4%); one major vessel injury (0.7%); one ureteral injury (0.7%); and one obturator nerve injury (0.7%). Overall, 16 of 148 patients (10.8%) required open conversion or postoperative open surgical repair. The most common postoperative complications were anastomotic leakage (6.8%), wound-related complications (4.7%) and perineal pain (4.7%). The bladder catheter was removed on day 7 or earlier in 73 cases (49.3%). The median time to ambulation was 1 day (mean 1.4, range 1-5). Oral intake was started on postoperative day 1 in 67 patients (45.2%) and on postoperative day 2 in 65 (43.9%). CONCLUSION: Although laparoscopic radical prostatectomy is technically demanding, reduced blood loss and shorter convalescence periods can be expected from the procedure. Surgeons should be aware of the disturbingly high morbidity rate related to early experience. By mastering laparoscopic skills and sharing knowledge, surgeons could reduce the impact of the learning curve required to complete this procedure competently.

Abstract：

Objective To present our initial experience in laparoscopic radical prostatectomy performed through an umbilical incision using a home-made multichannel port. Methods From August 2009 to March 2010, we performed single-port laparoscopic radical prostatectomy in 11 patients with localized prostate cancer. A home-made multichannel port was inserted extraperitoneally through a 3-cm umbilical incision. The single port extraperitoneal procedures included obturator fossa lymphadenectomy, radical prostatectomy and urethro-vesical anastomosis, while the urethro-vesical anastomosis was performed by a slip-knot running suture technique. Data were collected and analyzed prospectively. Results All cases were completed successfully, without conversion to a standard laparoscopic approach or open surgery except adding an additional port in one case. The average operative time was 256 minutes (range195-315), and the mean blood loss was 90 ml (range 20- 180), without any blood transfusion. The postoperative hospital stay was 15.4 days (range13- 24), and the Foley catheter was removed 12 days after surgery. No intraoperative complications occurred. One patient developed a vesico-rethralanastomosis leakage, 2 had lymphatic leakage and 1 had urinary tract infection,all of the cases were managed successfully with conservative treatment. Histopathological results showed negative surgical margine and negative lymph node dissection. All patients had no biochemical relapse after an average follow-up of 7 months. Conclusions Single-port laparoscopic radical prosta tectomy is feasible, cosmetic and minimally invasive with a low complication rate and good short-term outcome. Additional investigation is needed to evaluate the long-term safety and oncologic adequacy of this new approach.

Extraperitoneal radical prostatectomy Da Vinci

ObjetiveTo report the outcomes of 100 robotically assisted laparoscopic radical prostatectomies (RALPs), a minimally invasive alternative for treating prostate cancer.Patients and methodsIn all patients was used RALP with an extraperitoneal approach assisted by the da Vinci robotic surgical system (Intuitive Surgical, Sunnyvale, CA, USA). Prospective data collection included quality-of-life questionnaires, basic demographics (height, weight and body mass index), prostate specific antigen (PSA) levels, clinical stage and Gleason grade. Variables assessed during RALP were operative duration, estimated blood loss (EBL) and complications, and after RALP were hospital stay, catheter time, pathology, PSA level, return of continence and potency.ResultsThe mean (range) duration of RALP was 180 (140-295) min; all procedures were successful, with no intraoperative transfusions or deaths. The mean EBL was 300 mL (40 – 1100); 97% of patients were discharged home on the first day after RALP with a mean haematocrit of 36%. The mean duration of catheterization was 7 (5-21) days. The positive margin rate was 14% for all patients. The overall biochemical recurrence free (PSA level <0.1 ng/mL) survival was 95% at mean follow-up of 9.7 months. There was complete continence at 6 months in 95% of patients. At 1 year 78% of patients were potent (with or without the use of oral medications), 15% were not yet able to sustain erections capable of intercourse, and another 7% still required injection therapy.ConclusionRALP is a safe, feasible and minimally invasive alternative for treating prostate cancer. Our initial experience with the procedure shows promising short-term outcomes.
