The processus vaginalis transection method to prevent postradical prostatectomy inguinal hernia: long-term results

Abstract

Objective: To evaluate the long-term effect of the processus vaginalis transection method, which we previously developed to prevent postradical prostatectomy inguinal hernia.

Methods: Our hernia prevention procedure is designed to prevent postoperative indirect hernias. The procedure is performed in the following order: (1) the spermatic cord is isolated and mobilized in the pelvis, (2) the vas deferens is isolated from the spermatic cord and ligated, and (3) the processus vaginalis is dissected free of the other spermatic cord elements, mainly spermatic vessels, ligated near the peritoneum, and transected. Between February 2006 and August 2008, 435 consecutive patients underwent the inguinal hernia prevention procedure concurrently with open radical retropubic prostatectomy. The control group comprised 433 patients who had undergone radical retropubic prostatectomy without hernia prevention immediately before the introduction of this hernia prevention procedure was introduced (between January 2001 and January 2006).

Results: No significant complications associated with the hernia prevention procedure were observed, except for a few minor peritoneal injuries that were easily repaired during surgery. An inguinal hernia developed postoperatively in 109 of the 433 control patients (25.2%) during the median follow-up of 68 months. In contrast, 4 of the 435 patients (0.9%) who underwent the hernia prevention procedure developed an inguinal hernia during the median follow-up of 42 months.

Conclusion: The processus vaginalis transection method is safe and effective in the long-term prevention of postradical prostatectomy inguinal hernia.
