Brief Summary

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.

Detailed Description

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.

Study Groups

Conventional Linear Closure Arm

Patients undergo stoma reversal surgery with skin wound closed using conventional linear technique: simple interrupted Prolene sutures after standard internal layer closure. Postoperative care follows departmental protocols, with wound assessments for SSI and scar evaluation at follow-up.

Group Type: EXPERIMENTAL

Conventional linear skin closure

Intervention Type: PROCEDURE

During stoma reversal, skin wound closed with simple interrupted 3-0 Prolene sutures after standard internal and subcutaneous closure. Serves as active comparator to purse-string method; standard technique associated with higher SSI rates.

Purse-String Closure Arm

Patients undergo stoma reversal surgery with skin wound closed using purse-string technique: internal layers closed standardly, subcutaneous layer with Vicryl purse-string, skin with Prolene purse-string. Postoperative care follows departmental protocols, with wound assessments for SSI and scar evaluation at follow-up.

Group Type: ACTIVE_COMPARATOR

Purse-string skin closure

Intervention Type: PROCEDURE

During stoma reversal, internal layers closed standardly; subcutaneous tissue closed with continuous Vicryl purse-string suture, skin with Prolene purse-string suture. Distinguishes from linear closure by circular tightening technique to reduce SSI risk and improve cosmesis in pediatric patients.

Interventions

Purse-string skin closure

During stoma reversal, internal layers closed standardly; subcutaneous tissue closed with continuous Vicryl purse-string suture, skin with Prolene purse-string suture. Distinguishes from linear closure by circular tightening technique to reduce SSI risk and improve cosmesis in pediatric patients.

Intervention Type: PROCEDURE

Conventional linear skin closure

During stoma reversal, skin wound closed with simple interrupted 3-0 Prolene sutures after standard internal and subcutaneous closure. Serves as active comparator to purse-string method; standard technique associated with higher SSI rates.
