[Role of laparoscopy in the management of acute appendicitis]

Abstract

Minimal invasive surgery had a considerable impact on common surgical techniques and has almost replaced established operative procedures such as cholecystectomy. However, the laparoscopic approach for the treatment of acute appendicitis is still not very popular. We discuss the role of laparoscopy for appendectomy and include three studies from our institution (University Hospital Zürich, Switzerland) and prospective studies reported in the literature. We conclude that laparoscopic appendectomy, when compared with the open approach, has the following advantages for the diagnosis and treatment of acute appendicitis. (1) Diagnostic laparoscopy is an effective and relatively atraumatic tool to investigate the abdominal cavity, which results in a sensitivity of almost 100%. This allows for accurate decision making, which is especially advantageous in young women and obese patients. (2) Prospective studies demonstrate that laparoscopic appendectomy is at least as good as open appendectomy and that the laparoscopic approach results in a reduced postoperative infection rate. (3) The similar complication rate after laparoscopic appendectomy, when performed by residents rather than staff surgeons, underlines the feasibility and teaching potential of this minimal invasive procedure.
