Sutureless Appendectomy by Using Harmonic Scalpel: Is It Possible?

Laparoscopic appendectomy is a commonly performed procedure. The base of appendix is secured by various techniques (suture, LigaSure, endoloop, or hamlock clip). Harmonic scalpel (HS) may be used to seal the base of the appendix. The study was conducted to assess the efficacy of HS in laparoscopic appendectomy for sealing the base of the appendix. The patients were divided into two groups: group 1 in which base was secured by endoloop and group 2 in which base of the appendix was sealed by HS in a stepwise manner. We made a record of patients' age and gender, and operative time. The patients were followed for a period of 3 months from the time of discharge. During the study period of 4.5 years, 102 patients were in group 1 and 108 patients in group 2. Both groups were age and gender matched. Mean operating time for group 1 was 43.34 ± 6.7 minutes and that for group 2 was 28.46 ± 7.19 minutes ( < .0001). Complications included postoperative ileus (group 1 = 8, group 2 = 10) and surgical site infection (group 1 = 4, group 2 = 4,  > .05). It appears that use of HS for laparoscopic appendectomy is feasible and safe. Its results appear to be comparable with other methods of laparoscopic appendectomy. Complications are minimal. Further studies at other centers may substantiate our efforts.
