This randomized controlled trial compares purse-string versus conventional linear skin closure techniques in children undergoing stoma reversal surgery. The primary aim is to assess surgical site infection rates within 30 days and scar cosmesis at 3 months using the Manchester Scar Scale. Fifty patients (25 per group) will be randomized at Assiut University Pediatric Surgery Department to determine if purse-string closure reduces infections and improves scarring.

Stoma reversal surgery is commonly performed in pediatric patients, but complications including surgical site infection (SSI), poor scarring, anastomotic leak, paralytic ileus, adhesive intestinal obstruction, bleeding, and incisional hernia remain concerns. The frequency of SSI and scar formation is directly related to the wound closure technique employed. Skin wounds in stoma reversal are typically closed using conventional linear closure technique; however, this method carries a higher risk of surgical site infections. Studies in adults have demonstrated that purse-string wound closure technique achieves better cosmetic outcomes and reduced risk of SSI compared to conventional linear closure. However, high-quality data comparing these techniques in pediatric populations undergoing stoma reversal is lacking. This randomized controlled trial will enroll 50 pediatric patients (aged 1 month to 18 years) undergoing stoma reversal at the Pediatric Surgery Department, Assiut University Hospitals. Participants will be randomized using a lottery method in a 1:1 ratio to receive either conventional linear closure (Group A) using simple interrupted Prolene sutures or purse-string closure (Group B) using Vicryl for subcutaneous layers and Prolene for skin in a purse-string technique. All patients will undergo standard stoma reversal procedures and receive postoperative care per departmental protocols. Wounds will be evaluated after the first dressing change, at hospital discharge, during stitch removal, and at follow-up visits continuing for 3-4 months. Surgical site infection will be assessed using CDC criteria. Scar cosmesis will be evaluated at a minimum of 3 months post-surgery using the Manchester scar scale by three independent assessors. The study aims to compare the frequency of surgical site infections and cosmetic outcomes between the two closure techniques, providing evidence-based guidance for optimal wound closure in pediatric stoma reversal.
