Background: Wound dehiscence/burst abdomen is a very serious postoperative complication associated with high morbidity and mortality. It has a significant impact on health care cost both for the patient and the hospital. Abdominal wound dehiscence is the major cause of morbidity following any laparotomy whether elective or emergency. The aim of the study was to compare wound dehiscence between the patients underwent two different suture technique of rectus sheath closure.
Material and Methods: In our study total 480 subjects with perforation peritonitis who were operated through midline incision were included. They were divided into 2 groups 240 subject in each group:1) Test (interrupted suture) and2) Control group (continuous suture) group. In test group the abdominal closure was done by interrupted suture technique while in control group abdominal closure was done by continuous suture technique. Patients were followed up and wound dehiscence/burst abdomen was assessed at day 3, 7 and 1 month postoperatively.
Results: The mean age in group 1 was 49.60 years while in group 2 was 49.02 years. In both the groups male sex was predominant (78.3% and 75.8%). Most common diagnosis was peptic perforation followed by illeal perforation in both the groups. Incidence of wound dehiscence was significantly less in group 1 (7.9%) compared to group 2 (19.5%) and most of wound dehiscence occurred at 7th day postoperatively in both the groups.
Conclusions: The conclusion of our study is that rectus sheath closure by interrupted suture is better than continuous suture in terms of wound dehiscence.
