Comparison of stapling techniques and management of the mesoappendix in laparoscopic appendectomy.

Many techniques for laparoscopic appendectomy have been proposed with few comparative studies. We performed a retrospective review of all patients undergoing laparoscopic appendectomy for uncomplicated appendicitis from 2006 to 2011. Techniques were: (1) transection of the mesoappendix and appendix with a single staple line (SSL); (2) transection of the mesoappendix and appendix with multiple staple lines (MSL); and (3) transection of the mesoappendix with ultrasonic shears and the appendix with a single staple line (USSL).
