Abstract

Background: Laparoscopic appendectomy (LA), preferred for minimal invasiveness, requires effective mesoappendix dissection methods to avoid complications like massive bleeding or surgery conversion. This study compares ultrasonic dissection with suture ligation regarding operative time, per-operative bleeding, and post-operative complications. Methods: In this prospective randomized controlled trial at KIMS Hospital, Bengaluru, from January to July 2024, 90 patients with acute appendicitis were randomly assigned to ultrasonic dissection (n=44) or suture ligation (n=46). Key outcomes measured included operative time, per-operative bleeding, and post-operative complications, analyzed using SPSS 23.0. Results: The mean operative time was significantly less for ultrasonic dissection (63.568 ± 9.896 minutes) compared to suture ligation (84.788 ± 11.239 minutes; p<0.001). There was no significant difference in per-operative bleeding between the groups. Post-operative complications were similarly low and not statistically different between the groups. Conclusion: Ultrasonic dissection offers a more time-efficient method for mesoappendix management in laparoscopic appendectomy compared to suture ligation, with comparable safety outcomes.
