ObjectiveTo evaluate the efficacy and safety of Hem-o-lok clip for closing appendix stump in laparoscopic appendectomy.

MethodsEighty-two patients treated with laparoscopic appendectomy were randomly divided into the Hem-o-lok group(n=41) and control group(n=41).The appendiceal stump in the Hem-o-lok group and control group were clamped using Hem-o-lok and simple ligation or ligation combined with sewing using silk thread, respectively.The operation time, operation related complications, length of stay and hospitalization cost were compared between two groups.

ResultsThe operation time, intraoperative blood loss and postoperative anal exhaust time in Hem-o-lok group were significantly lower than those in control group(P < 0.01), but the differences of the hospitalization time and total hospitalization cost were not statistically significant(P>0.05).There was not reoperation patients in the Hem-o-lok group, and two patients were transferred to open surgery.There were not reoperation patients in the control group, and the difference of the patients transferring to open surgery between two groups was not statistically significant(P>0.05).The total incidence rate of complications in Hem-o-lok group was slightly lower than that in control group, but the difference of which was not statistically significant(P>0.05).

ConclusionsThe Hem-o-lok clip is effective and safe in the treatment of appendiceal stump, and it is simple to operate, and can effectively shorten the operation time.
