Background: In emergency and elective settings, some surgeons prefer continuous or interrupted closure of abdominal fascia, because in a continuous suturing, cutting out of even a single bite of tissue leads to opening of the entire wound and high risk of burst abdomen, whereas in interrupted method, they found much lower risk of burst abdomen. The aim is to assess the complication rate with the same closure technique between two different sutures. The best suture is one that maintains tensile strength throughout the healing process with good tissue approximation and less wound infection, is well tolerated by patient and is technically simple and expedient. The aim was to compare the non-absorbable sutures (nylon) and delayed absorbable sutures (polydioxanone (PDS)) for abdominal wall closure in cases of peritonitis. We used a different technique to close the abdominal wall fascia and study the postoperative complications.
