Three-year prospective outcomes of laparoscopic intraperitoneal on-lay mesh repair of abdominal incisional hernia.

Abstract

Incisional hernia (IH) can be treated with an intraperitoneal on-lay mesh (IPOM). This study aimed to evaluate the surgical outcomes, recurrence rates, and chronic pain after laparoscopic IH repair. The data of 50 patients who underwent laparoscopic IPOM repair between March 2018 and May 2021 were prospectively collected. The standard IPOM technique was used on 41 patients (82%), whereas the IPOM-plus technique was used on nine patients (18%). There was a history of IH repair for 12 patients (24%), and two of them recurrent hernias. The average body mass index was 24.7, and the average defect size was 17.6 cm2 . The mean operative time was 145.7 minutes, and the mean hospital stay was 3.5 days. There were minor complications in nine patients (18%), a case of bowel injury (2%), and a case of bladder injury (2%). Recurrent hernias were observed in three patients (6%) over a mean follow-up period of 17.9 months (4-36 months). One patient had postoperative chronic pain lasting 3 months. The width and size of the hernia were risk factors for recurrence. Laparoscopic IPOM repair was a safe and effective method of treating IH, with a low incidence of postoperative complications, chronic pain, and recurrence.
