Extracorporeal loop, Hem-o-lok clip, and Endostapler for Appendiceal Stump Closure in Laparoscopic Appendectomy: a Retrospective Cohort Study

Q: What does this research mean for the field?

During laparoscopic appendectomy, the use of an endostapler for appendiceal stump closure is associated with cases involving significantly larger appendix diameters and more intraoperative abscesses compared to loop or Hem-o-lok clip methods. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Key Points

To evaluate and compare the safety and clinical outcomes among extracorporeal loop, Hem-o-lok clip, and endostapler methods for appendiceal stump closure during laparoscopic appendectomy.
Retrospective cohort analysis of medical records from patients who underwent laparoscopic appendectomy for acute appendicitis between May 2023 and March 2025 at a single institution (N=368).
Patients were categorized by stump closure technique: extracorporeal loop, Hem-o-lok clip, or endostapler.
Demographic details, operative metrics, histopathology, Clavien-Dindo 30-day complications, and late postoperative complications were evaluated across groups.
The study included 368 patients: loop (n=201), Hem-o-lok clip (n=100), and endostapler (n=67).
Demographic characteristics and preexisting baseline comorbidities were balanced across all three surgical cohorts.
Patients receiving endostapler closure presented with significantly larger appendix diameter on computed tomography and a higher frequency of intraoperative abscesses.
