Laparoscopic Appendectomy with the Help of a Wire Snare

Abstract

This report describes the performance of a laparoscopic appendectomy (LA), a new technique using a "wire snare" without any specific complications. The snare consisted of an 18-gauge injection needle and folded fine wire, measuring 0.28 mm in diameter. LA was performed in 95 patients with acute appendicitis using a cheap and simple wire snare to catch the ligation thread of #0 silk. A good view of the appendix and mesoappendix was obtained in all cases by traction of the #0 silk. The operative time needed to perform LA using a wire snare for nongangrenous appendicitis in 77 cases overall, the first 10 cases, and the last 10 cases was 54 ± 17, 64 ± 5, and 33 ± 4 min, respectively. Two of the 95 patients required conversion to an open appendectomy because of technical difficulties due to the formation of an inflammatory mass. There were no complications associated with insertion of the snare. The wire snare is an innovative technique and does not increase the costs significantly, and should help reduce the number of trocar sites and the operative time, while also making an LA easier to perform.
