Abstract
Abstract Aim Previous studies on the repair of small umbilical hernias have suggested a lower recurrence rate with mesh compared to suture repair. A remaining important question is in what anatomical position the mesh should be placed. The purpose of this study was to investigate the outcome of using a standardized 4x4 cm onlay-mesh for umbilical hernias ≤2cm. Material and Methods A retrospective study was conducted at a single institution in Sweden on all umbilical hernia repairs during 2015-2019. The follow up time was at least four months. Patients were identified using the hospital medical record database. Repairs performed with suture, sublay, ventral patch or laparoscopic mesh positioning were excluded. Patient’s demographics, comorbidities, intra – and postoperative details were considered. Primary outcome was surgical site complications within 30 days. Secondary outcome was recurrence. Results 80 patients were repaired with a small onlay-mesh for an umbilical hernia ≤ 2 cm and were included for statistical analysis. Median (range) follow-up time was 29.0 (4.3-50.1) months. Median age was 46 (26-76) years old. Median body mass index was 28 (19-38) kg/m2. Men to female ratio was 2.1. 4 patients were identified with a surgical site postoperative complication; 3 with seroma and 1 with superficial wound infection. 3 of these were given antibiotics. 2 patients were treated with wound opening bedside. There were no registered cases of a recurrence. Conclusions Repairing small umbilical hernias with a small onlay-mesh was safe with a low surgical site complication rate. Randomized trials are needed to assess weather mesh reduce recurrences in umbilical hernia repairs ≤2cm.
