Mesh alone versus combined darn and mesh in primary inguinal hernia repair in adults: a randomized control trial.

Despite the availability of laparoscopy, open surgery remains the most common practice for primary inguinal hernia repair in general surgery. This study aimed to evaluate the combined mesh and darn (CMD) repair compared to mesh alone (MA) repair in treating adult inguinal hernias regarding recurrence and postoperative complications. We conducted a prospective randomized study, including 330 patients with primary inguinal hernias who underwent primary inguinal hernia repair at our facilities between February 2015 and January 2018. Time spent in the hospital, time to resume regular activities, postoperative sequelae, and recurrence rates were assessed. Patients were randomly assigned to 2 groups: CMD repair was performed on 165 patients (Group 1), and MA repair was done on 165 patients (Group 2). Patients were monitored for three years. The average operation time for MA was 62.2 minutes, compared to 72.9 minutes for CMD. The average time to return to normal work was comparable for both groups at around 3 weeks. In Group 2, 12 (7.1%) patients experienced postoperative complications and 3 (1.7%) recurrences. In the CMD repair group, 13 (8.1%) patients had postoperative complications, but no recurrences were observed. Hospitalization duration and postoperative pain were similar between the two groups. At the three-year follow-up, the CMD repair demonstrated a lower recurrence rate than MA, while both groups had similar postoperative complications, hospital stays, and return to normal activities. The operative time was slightly longer for CMD repair compared to MA repair.
