Comparison of the non-absorbable polymer clips, knot-tying, and loop ligature appendiceal stump closure methods in laparoscopic appendectomy.

OBJECTIVE

In laparoscopic appendectomy (LA), closure of the appendix stump is important. This method must be safe and easy-to-use as well as an economical one. We compared three methods of the appendix stump closure in terms of safety, easiness, and financial cost.

MATERIALS AND METHODS

Three-hundred and ten LA patients operated between January 2011 and December 2019 and appendix stump was closed using one of the three methods, namely, non-absorbable polymeric clips (Group 1, n = 126), knot-tying group (Group 2, n = 101), and laparoscopic loop ligature group (Group 3, n = 83) were retrospectively analyzed in terms of stump leakage, infection, operation, and hospital stay duration.

RESULTS

There were 148 female and 162 male patients. The mean age was 33.57 ± 12.60 years. There was not any appendiceal stump leakage nor intra-abdominal infection in none of the groups. Local trocar site infection in 11 patients was medically treated. Surgical site infection and hospital stay period did not show statistically important difference among the groups. The operation duration in Group 1 was found to be shorter compared to the other groups.

CONCLUSIONS

All three techniques are safe in LA. Non-absorbable polymer clips provide a shorter operation time. Extracorporeal knot-tying with knot-pusher provides the cheapest closure of the stump.
