Kugel hernia repair: open "mini-invasive" technique. Personal experience on 620 patients.

A large monoinstitutional series adopting the Kugel retroparietal technique for inguinal hernia surgery is analysed. Our aim is to assess the "mini-invasiveness" of this technique. Six hundred and twenty patients (pts) affected by monolateral inguinal hernia were treated with a preperitoneal alloplasty with a posterior approach (Kugel hernia repair, KHR) between January 2002 and September 2004. The surgical incision extension was 3.5 cm on average (range 2-4.5). The mean operation time was 33 min (range 20-45). Spinal anaesthesia and ambulatory procedure were applied in 595 cases (96%). Postoperative complications affected 20 pts (3%). The postoperative pain was well controlled. No chronic neuropathic pain was registered at follow-up. Patients resumed work after an average of 9 days (range 7-12) from operation. Recurrence rate was 0.8%. Conclusions. The Kugel hernia repair satisfies the standards to be awarded as a "mini-invasive" technique.
