Comparison of non absorbable polypropylene and Absorbable polydioxanone suture for umbilical Port site closure - a randomised controlled trial.

Abstract

ABSTRACT Introduction: Laparoscopic surgery has revolutionized modern medicine, offering patients reduced postoperative pain, shorter hospital stays, and faster recovery compared to traditional open procedures. The umbilical port, typically the largest (10–12 mm) and most frequently used site for camera access, presents unique challenges. Due to its anatomical location and the thickness of the underlying fascia, improper closure can lead to complications such as surgical site infections (SSIs), hematomas, seromas, or port site herniation. These complications not only prolong recovery but also increase healthcare costs and patient morbidity. Despite advancements in surgical techniques, the optimal method for umbilical port closure remains debated, particularly regarding the choice of suture material. The umbilical port’s unique vulnerability to complications—owing to its size, location, and the dynamic stresses exerted by abdominal movement—makes it an ideal focus for investigating suture material efficacy. A suture material’s physical properties—such as stiffness, knot profile, or interaction with adjacent tissues—may influence these outcomes, yet this relationship remains poorly characterized. With this background, the study was done with the objectives of comparing post operative port site complications (pain and surgical site infections), after closure of 10mm umbilical port site with non-absorbable polypropylene and absorbable polydioxanone suture in patients undergoing elective laparoscopic surgeries.
