Comparative study of wound healing following purse-string closure versus conventional linear closure for stoma reversal

Abstract

Stoma closure is associated with several complications, wound infection being the most common. This study is done to establish that purse string suture closure method for stoma closure is superior to the conventional linear mattress closure and is associated with better wound healing cosmesis. This Prospective randomized controlled study enrolled 80 patients who underwent stoma closure from April 2021 to March 2022 in department of General Surgery in IGIMS, Patna. Patients were divided in two groups inclusive of ileostomy and colostomy based on type of closure technique. Conventional linear closure method was applied to Group A and purse-string technique applied to Group B patients. All Patients were followed regularly upto three months after operation. Rate of infection, pain as assessed by VAS score and satisfaction as assessed by POSAS Score were done. Purse string Closure had better outcome in terms of wound infection rate and Cosmetic results over a 3 months follow up. Ten patients in Group A and 2 from Group B out of 40 patients had wound infection. Patients with purse-string suture had statistically significant greater satisfaction over 3 months. Medium operative time of Group A was 100 minutes and that of Group B was 98 minutes. There were no significant difference in regards duration of hospital stay was more in Linear Group than Purse String (Group B). Purse-string closure was associated with better cosmesis and lower infection rate in comparison to Linear conventional closure.
