Randomized Controlled Trial of Comparison of Absorbable Extra Long-Term (Poly Hydroxy Butyrate) Suture Versus Non-Absorbable (Polypropylene) Suture for Abdominal Wall Closure

Abstract

Introduction: In patients undergoing midline incisions, rectus sheath can be closed with continuous or interrupted suture using
absorbable or non-absorbable materials. Despite major improvements in antibiotics, better anesthesia, superior instruments,
earlier diagnosis of surgical problems, and improved techniques for post-operative vigilance, post-operative complications such as
incisional hernias, burst abdomen, and wound infections continue to occur, which causes significant surgical health-care problem.
Aims and Objectives: The objectives of the study were to continuous technique with non-absorbable sutures (polypropylene)
– Group I and to interrupt technique with non-absorbable suture (polypropylene) – Group II.
Materials and Methods: Randomized controlled, prospective study on 271 patients with primary elective midline laparotomy
in Mahatma Gandhi Memorial Hospital. Patients operated from January 2018 to June 2019 are included in this study and are
followed up for a minimum period of 1 year.
Observation and Results: Group I includes 102 patients with continuous technique using non-absorbable polypropylene, Group
II includes 91 patients with interrupted technique using non-absorbable polypropylene, and Group III includes 78 patients with
continuous slowly absorbable polyhydroxybutyrate.
