    Abstract:
    Background: In general, the three main options for stump closure in laparoscopic appendectomy are clips, endoscopic staplers and endoloops. However, there is no gold standard, especially regarding complicated acute appendicitis which is generally associated with worse outcomes.Objectives: We aimed to assess the outcomes of different stump closure techniques during laparoscopic appendectomies for complicated appendicitisMethods: Our multicenter observational study of 18 surgical units assessed the outcomes of 1269 laparoscopic appendectomies for complicated appendicitis that used the three main stump closure techniques: clips, staplers and endoloops. Groups were compared in terms of peri- and postoperative outcomes.Results: Staplers were superior in terms of overall morbidity (9.79 vs. 3.29% vs. 7.41%, p = .017) and length of stay (4 vs. 3 vs. 4 days, p < .001) respectively for clips, staplers and endoloops. However, no differences in major complication rates, postoperative intraabdominal abscess formation, reintervention rates and readmission rates were found.Conclusion: Although our results show some clinical benefits of staplers for appendix stump closure, they are based on a non-randomized group of patients and are therefore prone to selection bias. Further well-designed trials taking into consideration not only the clinical benefits, but also, the economic aspects of the surgical treatment of complicated acute appendicitis are needed to confirm our results.
