Objective Polymeric (Hem-o-lok) clips represent a novel technique with which to ligate the appendiceal stump following laparoscopic appendectomy. We compared the outcomes of using polymeric clips versus endostaplers for complicated and uncomplicated appendicitis. Methods Six hundred seventy-three consecutive patients undergoing laparoscopic appendectomy with polymeric clips or endostaplers for acute appendicitis were assessed. The primary outcome was the incidence of intra-abdominal abscesses. Predictors of postoperative intra-abdominal abscesses were calculated using univariate and multivariate analyses. Results Polymeric clips were used in 65% of patients and endostaplers were used in 35%. Hem-o-lok clips were not only applied in patients with uncomplicated appendicitis (83%), but also in those with complicated appendicitis (26%). The frequency of intra-abdominal abscesses using polymeric clips and endostaplers was similar in both patients with uncomplicated appendicitis (1% vs. 3%, respectively) and complicated appendicitis (2% vs. 6%, respectively). The univariate and multivariate analyses showed that the stump closure technique was not a risk factor for postoperative abscesses. Conclusions Closure of the appendiceal stump using the nonabsorbable Hem-o-lok ligation system in patients with both uncomplicated and complicated appendicitis is a safe alternative to the application of endostaplers.
