Appendiceal stump closure using polymeric clips reduces intra-abdominal abscesses.

Area of Science:

• Surgical Innovation
• Minimally Invasive Surgery
• Gastrointestinal Surgery

Background:

• Laparoscopic appendectomy is standard for acute appendicitis.
• Securing the appendiceal stump is crucial to prevent complications.
• Polymeric clips (hem-o-lok) offer a novel method for stump closure.

Purpose of the Study:

• To evaluate the efficacy of the hem-o-lok ligation system.
• To compare hem-o-lok clips against conventional devices (endoloops).
• To assess the rate of postoperative intra-abdominal abscesses.

Main Methods:

• Retrospective analysis of 813 patients undergoing laparoscopic appendectomy.
• Comparison of hem-o-lok clips versus endoloop sutures for appendiceal stump closure.
• Univariate and multivariate analyses to identify risk factors for abscesses.

Main Results:

• Hem-o-lok clips were used in 54% of patients, endoloops in 46%.
• Endoloop application and lack of postoperative antibiotics were independent predictors of abscesses.
• The odds ratio for abscesses with hem-o-lok versus endoloop was 0.25 (p < 0.008).

Conclusions:

• The hem-o-lok ligation system significantly reduced intra-abdominal abscess rates.
• Non-absorbable hem-o-lok clips are a safer alternative to endoloops for appendiceal stump closure.
• This technique contributes to improved outcomes in laparoscopic appendectomy.
