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

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.

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.

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).

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.
