The use of a single Hem-o-lok clip in securing the base of the appendix during laparoscopic appendectomy

During laparoscopic appendectomy, the standard technique in securing the base of the appendix is by endoloop ligatures or a stapler. We earlier demonstrated the possibility of the application of a double Hem-o-lok(®) clip in securing of the base of the appendix. The application of only one plastic clip would, however, lower the cost of the laparoscopic procedure even further and shorten the surgery time. The objective of this prospective study was to evaluate the possible advantages of securing of the base of the appendix using only one Hem-o-lok clip. The 90 patients with acute appendicitis were randomly divided into three groups: In the first group, the base of the appendix was secured using one endoloop ligature, in the second group using a 45-mm stapler, and in the third group using only one nonabsorbable Hem-o-lok clip. The data collected included age, gender, surgery time, time of endoloop/stapler/clip application, hospital stay, costs associated with these, and intra- and postoperative complications. There were no significant differences in hospital stay among the three groups of patients; but the average time of the operation was significantly longer in the endoloop group than in the stapler group (P=.002), whereas the endoloop and Hem-o-lok groups were not statistically different (P=.22). The time of application of the endoloop was significantly longer than for the stapler (P
