Determination of risk factors for conversion from laparoscopic to open appendectomy in patients with acute appendicitis.

Background: Acute appendicitis is the most common cause of surgical emergencies. It can be difficult to distinguish cases of acute appendicitis that should be managed by laparoscopic appendectomy (LA) from those that should be managed by open surgery. This study aimed to prevent the inappropriate choice of technique and associated complications by identifying potential risk factors for conversion from laparoscopic to open appendectomy (OA) at the time of initial surgical assessment.
