Laparoscopic Versus Open Appendectomy

The laparoscopic appendectomy was performed with three trocars. Pneumoperitoneum was created using an open Hasson technique. The mesoappendix was divided using a harmonic scalpel or endoscopic tissue fusion device. The appendix was divided by placing one endoscopic loop and cut with harmonic scalpel. The specimen was removed through the umbilical port.

The open appendectomy was carried out in the standard way with McBurney muscle splitting incision (in supine position).
