Open or laparoscopic surgery for acute appendicitis? Why and what is your evidence?! –
There have been a number of well conducted RCT and meta-analysis which clearly show that a laparoscopic approach has various advantages over open, including a decreased length of hospital stay, fewer complication and an earlier return to work. The Cochrane review by Jaschinski et al. has pooled some 85 studies to provide substantial evidence to the benefit of laparoscopic appendicectomy.
