To Compare the Incidence of Complications on using Delayed Absorbable Suture (PDS - Polydioxane) and Non Absorbable Polyethelene Glycol (Nylon) for Abdominal Wall Closure

Introduction - Laparotomy is a common surgical procedure performed in a tertiary care centre for various surgical conditions. Healing of these laparotomy wounds depends on various local and systemic factors including selection of proper suture material. This present study was undertaken to compare complications between usage of PDS and Nylon for abdominal wall closure. Methods- 60 patients undergoing laparotomy with vertical midline incision were included in the study. The incidence of complications including post operative pain, surgical site infection and incisional hernia were compared and data represented in the form of percentages with bar diagrams and pie charts. Results- the incidence of post operative pain on POD 1 was same for both the groups, however only 13 out of 30 cases operated with PDS reported of pain on POD 7 while 18 out of 30 had pain on Pod 7. The incidence of pain further reduced on POD 14 when only 2 out of 30 patients in group A had pain whereas 7 out of 30 patients complained of pain in Group B. On POD 30, there was no pain reported in group A and 3 patients had pain in group B.5 out of 30 patients who had closure with PDS had superficial surgical site infection whereas 12 patients had surgical site infection with Nylon. Wound dehiscence was seen in only 1 out of 30 patients who had closure with PDS whereas 5 out of 30 patients had wound dehiscence whose closure was done with nylon. There was only 1 incidence of incisional hernia reported in a case operated with nylon. Conlusion- Based on the observations made in this study, it has been concluded that continuous mass closure technique using Polydioxanone (PDS) for closure of vertical midline laparotomy incision is better than Nylon in preventing the wound Complications
