[Laparoscopic surgery--evidence-based ?].

The literature has been searched for current results in laparoscopic cholecystectomy, hernia repair, appendectomy and fundoplication. This was performed as a systematic review. Laparoscopic cholecystectomy was judged to be safe and cost/effective, with good patient acceptability. However a need for further studies is indicated. Laparoscopic technique in hernia repair has a longer learning curve and is more expensive than open repair, with no major difference in recurrence rates. It is preferable in bilateral repairs. Laparoscopic appendectomy in the hands of experienced surgeons is cost/effective. Time to recovery is shorter and the rate of infectious complications is lower than in conventional procedures. There are still too few results reported from laparoscopic fundoplication to permit reliable conclusions.
