Background:
The optimal method for appendix stump closure in laparoscopic appendectomy (LA) remains debated. This study aims to evaluate the impact of suture-based closure and Hem-O-lok techniques on postoperative complications following LA for uncomplicated appendicitis.
Methods:
A retrospective analysis was conducted on patients with uncomplicated appendicitis treated by LA from January 2019 to December 2021. These patients were categorized into two groups: the suture-based closure group (223 cases) and the Hem-O-lok group (272 cases). Propensity score matching addressed potential discrepancies between the groups. Intraoperative and postoperative parameters of both groups were then compared.
Results:
Post-matching, the operative duration in the suture-based group was longer than in the Hem-O-lok group (45.9 ± 9.7 min versus 42.8 ± 8.9 min, P = 0.001). The incidence of postoperative intra-abdominal abscesses and fluid collections was significantly lower in the suture-based closure group (P = 0.032). Multivariate logistic regression analysis revealed that the Hem-O-lok clamp technique [odds ratio (OR) = 5.69, 95% confidence interval (CI): 1.01-64.25, P = 0.047] was a notable risk factor for intra-abdominal abscesses and fluid collections.
Conclusions:
The suture-based closure technique significantly reduced the incidence of postoperative intra-abdominal abscesses and fluid collections compared with the Hem-O-lok technique in patients undergoing LA for uncomplicated appendicitis.
