The effect of previous transperitoneal laparoscopic inguinal herniorrhaphy on transperitoneal laparoscopic radical prostatectomy.

Purpose: Previous laparoscopic herniorrhaphy has been considered a contraindication to laparoscopic radical prostatectomy (LRP). In this study we analyzed the impact of previous laparoscopic or open inguinal hernia repair on the outcome of transperitoneal laparoscopic radical prostatectomy using the Heilbronn technique.

Materials And Methods: In our database of 1,089 patients with LRP we identified 20 who underwent transperitoneal LRP and had a history of transperitoneal laparoscopic inguinal herniorrhaphy using prosthetic mesh (group 1). The outcome in that group was compared to that of 20 matched pair patients of a total of 95 in whom LRP was performed following open inguinal herniorrhaphy (group 2) and 20 matched pair patients of a total of 771 without previous surgery (group 3). Perioperative parameters (operative time, blood donation and complications) and postoperative results (duration and amount of analgesic treatment, catheterization and the continence rate) were analyzed.

Results: According to the matched pair algorithm the 3 groups did not differ with respect to age (63.8, 66.2 and 63.0 years, p = 0.226), prostate volume (47.2, 43.3 and 47.7 gm, p = 0.501) or body mass index (26.1, 25.8 and 26.2 kg/m, respectively, p = 0.641). Ten pelvic lymphadenectomies and 8 nerve sparing (4 unilateral and 4 bilateral) procedures were performed per group. Ten and 12 patients in groups 1 and 2 had a history of bilateral herniorrhaphy, while previous unilateral herniorrhaphy was noted in the remaining 10 and 8, respectively. Mean operative time +/- SD (203.3 +/- 3.54, 196.7 +/- 43.7 and 214.7 +/- 37.7 minutes, p = 0.346) and mean catheterization time (8.1 +/- 2.8, 7.7 +/- 2.5 and 7.4 +/- 2.1 days, respectively, p = 0.684) did not differ significantly among the 3 groups. However, the mean amount of narcotic analgesic was significantly higher in group 1 compared with groups 2 and 3 (32.1 +/- 11.9, 21.8 +/- 11.9 and 19.5 +/- 10.1 mg, respectively, p = 0.002). Continence rates were similar in the groups at 88%, 87% and 92%, respectively, 1 year after surgery.

Conclusions: Previous laparoscopic inguinal herniorrhaphy using prosthetic mesh does not adversively affect the operative outcomes or functional results of LRP, while the total amount of narcotic analgesics was significantly higher, reflecting increased postoperative morbidity.
