A 12-year experience of using the Kugel procedure for adult inguinal hernias via the internal ring approach

Abstract

Purpose: Kugel procedure is a classic preperitoneal herniorrhaphy via the posterior approach for inguinal hernias but it has a steep learning curve. The aim of the study is to evaluate the efficacy of the Kugel procedure via the internal ring approach.

Methods: Kugel procedures via the internal ring approach were performed on 3673 patients with inguinal hernias between September, 2005 and August, 2017. Demographic data, peri-operative data and postoperative data were collected to evaluate of the efficacy of this technique.

Results: None of the patients with inguinal hernias who underwent the Kugel procedure via the internal ring approach was converted to other procedures. The mean operation time for a unilateral hernia was 46.3 ± 15.2 min, with a mean blood loss of 28.9 ± 10.5 mL. The mean visual analogue scale score on postoperative day 1 was 3.1 ± 0.9. Drainage tubes were placed in 266 patients and were removed after a mean duration of 2.8 ± 0.5 days. The mean postoperative hospital stay was 1.2 ± 0.8 days. There were no serious intra-operative complications. Postoperative complications included seroma (n = 84), haematoma (n = 28), ecchymosis (n = 33), superficial incision infection (n = 1), recurrence (n = 1) and mild chronic pain (n = 11).

Conclusions: The Kugel procedure via the internal ring approach is a safe, feasible and cost-effective technique for inguinal hernias that retains the benefits of the standard Kugel procedure and is easier to master.
