[Appendectomy: open versus laparoscopic versus single port : Evidence for choice of surgical procedure].

The treatment of choice in acute appendicitis is still the surgical removal of an inflamed vermiform appendix. There is still some disagreement regarding the optimal access route, i.e. conventional open or minimally invasive. The best available evidence is used to answer the question of the current optimal choice of procedure. For laparoscopic appendectomy there are evidence-based benefits in terms of access trauma, postoperative pain, wound infection rates and convalescence. For the alternative minimally invasive procedure single port appendectomy, mini-laparoscopic appendectomy or NOTES appendectomy, there is still a lack of scientific evidence to advocate the broad clinical use of these procedures. It is recommended that whenever the infrastructure permits, laparoscopic appendectomy should be the treatment of choice.
