Laparoscopic versus open appendectomy for acute appendicitis: a metaanalysis.

Background: Currently, laparoscopic appendectomy (LA) provides a safe and effective alternative to open appendectomy (OA), but its use remains controversial. This study aimed to evaluate the efficiency and safety of LA through a metaanalysis.

Methods: Randomized controlled trials (RCTs) comparing LA and OA published between January 1992 and February 2010 were included in this study.
