Sutureless versus purse string with complete sac dissection in laparoscopic inguinal hernia repair in children: a randomized clinical trial

Introduction Pediatric inguinal hernia is a common surgical condition with a cumulative incidence of 4.2%. Minimal invasive surgery is playing a growing role in the treatment of this condition. We compared the outcomes of laparoscopic sutureless herniotomy and purse string with sac dissection repair with regards to complications and operative time. Methods One hundred fifty-two patients were operated on in two centers with two different techniques: sac dissection and purse-string suture, and sutureless repair. Operative time and recurrence were the main outcomes for comparison. Results Sutureless repair has a shorter operative time (29 ± 10 min) compared to purse string repair (38 ± 13 min). The recurrence rate showed no statistical significance difference. However, the recurrence rate of sutureless repair was three times higher than that of purse string repair, and all recurrences were in large defects of 10–15 mm. Conclusions Sutureless repair is safe for defects up to 10 mm with excellent operative time. However, it had an unfavorable outcome in larger defects.
