Effectiveness of different appendiceal stump closure methods in laparoscopic appendectomy a network meta-analysis.

PURPOSE

Choosing the best stump closure method for laparoscopic appendectomy has been a debated issue, especially for patients with acute appendicitis. The lack of consensus in the literature and the diverse techniques available have prompted the need for a comprehensive evaluation to guide surgeons in selecting the most optimal appendiceal stump closure method.

METHODS

A comprehensive search was conducted on multiple databases from inception until December 2023 to find relevant studies according to eligibility criteria. The primary outcome was the incidence of total complications.

RESULTS

25 studies with a total of 3308 patients were included in this study, overall complications did not reveal a significant advantage for any intervention (RR = 0.72, 95% CI: 0.53; 1.01), Superficial and deep infection risks were similar across all methods, Operative time was significantly longer with endoloop and Intracorporeal sutures (MD = 7.07, 95% CI: 3.28; 10.85) (MD = 26.1, 95% CI: 20.9; 31.29).

CONCLUSIONS

There are no significant differences in overall complications among closure methods. However, Intracorporeal sutures and endoloop techniques were associated with extended operative durations.
