Objectives: To evaluate the role of simultaneous laparoscopic mesh prosthetic hernioplasty during laparoscopic radical prostatectomy (LRP), because 5% to 10% of candidates for radical prostatectomy present with a detectable inguinal hernia at their preoperative physical examination. Moreover, data have suggested a greater incidence of inguinal hernia after open radical prostatectomy.
Methods: During 1035 LRP procedures, 50 laparoscopic mesh prosthetic hernioplasty procedures were performed in 37 patients (3.6%) for 13 bilateral and 24 unilateral inguinal hernias. We compared the outcome of LRP with simultaneous laparoscopic inguinal hernioplasty (group 1) with that of 37 match-paired patients treated by LRP alone (group 2). Both groups were matched according to age, prostate-specific antigen level, prostate volume, pathologic stage, and Gleason score. Perioperative parameters (ie, operative time, analgesic requirements) and postoperative results were analyzed.
Results: The patient age was 64.1 +/- 6.4 years versus 62.8 +/- 4.9 years old and had a body mass of 26.5 +/- 3.0 versus 27.4 +/- 3.2 kg/m2 in groups 1 and 2 (with and without laparoscopic hernioplasty), respectively. The mean operating time (221.9 versus 191.2 minutes, P = 0.011) and the total amount of narcotic analgesic requirements (26.8 mg versus 17.5 mg, P = 0.026) was significantly increased in the patients who underwent simultaneous laparoscopic inguinal hernia mesh repair. No statistically significant difference was found in the complication rate (4% versus 2%), median catheter time (7 days), and positive surgical margins (21.8%).
Conclusions: Simultaneous repair of inguinal hernia during LRP using prosthetic mesh is feasible without adverse effects on surgical and functional parameters. Neither the transperitoneal nor extraperitoneal approach is associated with an increase in complications or morbidity. However, an extraperitoneal access allows an easier repair without the refixation of the peritoneum.
