INTRODUCTION: To describe the technique of total extraperitoneal inguinal hernia repair performed during Robot-assisted Endoscopic Extraperitoneal Radical Prostatectomy (R-EERPE) and to present the initial outcomes. MATERIAL AND METHODS: 12 patients underwent inguinal hernia repair during 120 R-EERPEs performed between July 2011 and March 2012. All patients had a clinically palpable inguinal hernia preoperatively. The hernia was repaired using a Total Extraperitoneal Patch (TEP) at the end of the procedure. RESULTS: Sac dissection and mesh placement was simpler compared to conventional laparoscopy due to improved, magnified, 3-D vision along with 7° of movement, and better control of mesh placement. The median operating time was 185 minutes, with on average, an additional 12 minutes incurred per hernia repair. The median blood loss for the procedures was 250 ml, and the mean pathological prostate weight was 55 gm. No additional blood loss was noted and there were no postoperative complications. None of the patients had a recurrence at 12 months. We await long-term follow-up data. CONCLUSIONS: Robot-assisted TEP is feasible and should be considered in patients with hernia at the time of R-EERPE.

Several techniques have been introduced to improve early postoperative continence. In this study, we evaluated the impact of bladder neck (vesicourethral anastomosis) suspension on the outcome of extraperitoneal endoscopic radical prostatectomy (EERPE). In this research, a total of 180 patients underwent EERPE. Group 1 included patients who underwent nerve-sparing EERPE (nsEERPE) (n=45), and Group 2 included patients who underwent nsEERPE with bladder neck suspension (BNS, n=45). Groups 3 (n=45) and 4 (n=45) included patients who received EERPE and EERPE with BNS, respectively. Patients were randomly assigned to receive BNS with their nsEERPE or EERPE procedure. Perioperative parameters were recorded, and continence was evaluated by determining the number and weight of absorbent pads (pad weighing test) on the second day after catheter removal and by a questionnaire 3 months postoperatively. Two days after catheter removal, 11.1% of Group 1, 11.1% of Group 2, 4.4% of Group 3 and 8.9% of Group 4 were continent. The average urine loss was 80.4, 70.1, 325.0 and 291.3 g for the each of these groups, respectively. At 3 months, 76.5% of Group 1 and 81.3% of Group 2 were continent. The continence figures for Group 3 and 4 were 48.5% and 43.8%, respectively. Similar overall rates were observed in all groups. In conclusion, although there are controversial reports in the literature, early continence was never observed to be significantly higher in the BNS groups when compared with the non-BNS groups, regardless of the EERPE technique performed.

We report the outcome of 2400 endoscopic extraperitoneal radical prostatectomy (EERPE) cases performed in three institutions, with emphasis on the evolution of the EERPE technique.In total, 2400 EERPE procedures were performed in three institutions. Several surgeons performed the operations. The presented cases also include the learning curve of the surgeons. EERPE was performed in all cases of localized prostate cancer with the same indications to open and transperitoneal laparoscopic radical prostatectomy.Average patient age was 63.3 years (range 41-81 years), and mean preoperative prostate specific antigen (PSA) level was 9.8 ng/mL (range 0.08-93 ng/mL); 857 (38%) patients had previously undergone abdominal or pelvic surgery, while 143 (5.8%) patients had prior prostatic treatment. Pelvic lymph node dissection took place in 1219 (50.8%) patients. Bilateral nerve sparing was performed in 672 patients and unilateral in 284 patients; 100 patients underwent intraoperative hernia repair with mesh placement (82 unilateral and 18 bilateral). Mean operative time was 150.7 minutes (range 50-340 minutes). Conversion to open surgery was never deemed necessary. Fifteen patients received transfusion (0.7%). The mean catheterization time was 6.19 days (range 3-40 days). Overall, 71.7% and 94.7% of the patients were continent at 3 and 12 months, respectively. Totally, 956 patients were treated with nerve-sparing procedure either interfascial or intrafascial; 672 patients underwent bilateral neurovascular bundle preservation, and 284, unilateral. Younger patients tend to have better postoperative potency. Bilateral nerve-sparing EERPE in patients younger than 55 years results in potency rate of 32.4%, 75.3%, and 84.9% at 3, 6, and 12 months postoperatively.The functional and oncological outcome of EERPE is comparable to other approaches for radical prostatectomy. Continuous refinements contribute to the improving outcome of the procedure. Long-term results especially in terms of oncological efficacy are expected.

New operating procedures that spare the important neural structures of the urogenital tract have led to improved functional results in terms of bladder function, urinary continence and erectile potency. Well-described examples are nerve-sparing radical prostatectomy [1–3] and cystectomy (continence, potency) [3, 4], ureteric antireflux surgery (bladder function) [5], extended radical hysterectomy with total mesometrial resection (bladder function) [6] and rectal resection (continence, bladder function, potency) [7].

Whilst the patient is supine, following induction of anaesthesia, a urinary catheter is inserted. The patient is now rotated to the lateral position and the urinary bag is placed either at the top or bottom end of the bed for access by the anaesthetist. The legs are separated and protected with either pillows or a specially designed foam or rubber device between them as seen in the inset, in order to relieve any weight on pressure points, while the legs are slightly flexed at the knees. All other bony points, including shoulders and hips, are protected by the rubber or foam mat that is positioned on the operating table. The head and neck are supported with either pillows or a rubber head ring in order to maintain them in a neutral position. Depending on the softness of the table mattress, an axillary rubber roll may be required (not illustrated in these images) to prevent brachial plexus injury.

To compare the outcome of intrafascial nerve-sparing endoscopic extraperitoneal radical prostatectomy (nsEERPE) with interfascial (standard) nsEERPE.Four-hundred patients underwent nsEERPE; 200 patients underwent bilateral intrafascial nsEERPE (group A) and 200 bilateral standard nsEERPE (group B). Tumor stages of T1 and T2a, prostate-specific antigen level10 ng/mL, maximal Gleason score 3+4 (not 4+3) and preoperative potency were considered as candidates for nsEERPE. Patients were randomized to the aforementioned groups. Perioperative data, and functional and oncological outcome were reviewed. Patients not requiring any pads or requiring 1 pad for safety were defined as continent. Patients responding positively to sexual encounter profile diary question numbers 2, 3, and 5 were considered as potent.Perioperative data were similar between groups. At 3 months, 74% of group A and and 63% of group B were continent. At 6 months, the respective figures were 87.9% and 76.2%, respectively (A, B). At 12 months, 93.2% of group A and 90.7% of group B were continent. Potency rates of group A were 93.5% (55 years), 83.3% (55-65 years), and 60% (65 years) at 12 months. The respective figures for Group B were 77.1%, 50%, and 40%. Positive surgical margins were detected in 9% and 9.5% of groups A and B, respectively.Intrafascial nsEERPE provides significantly better potency in patients55 years of age at 12 months and in patients 55-65 years of age at 6 and 12 months, with probably limited effect on the oncological outcome. Significantly improved continence was observed at 3 and 6 months in favor of intrafascial nsEEPRE.
