title: Role of laparoscopy in hepatic cyst surgery.
abstract: BACKGROUND
  Hepatic cysts are detected incidentally in 2.5-5% of the population. Only about 15% of such cysts are symptomatic. Since laparoscopic deroofing for liver cysts was first described in 1991 there have been a number of reports of successful laparoscopic management of hepatic cysts, including the laparoscopic management of complex and parasitic cysts.
  
  
  METHODS
  A systematic review of English-language articles on the subject appearing in journals through May 2002 was conducted using the Medline database.
  
  
  RESULTS
  Only a minority of cystic liver lesions need treatment, and the therapeutic approach is guided by the type of cyst. Laparoscopic deroofing (combined with omentoplasty and/or oversewing) of uncomplicated liver cysts is associated with a recurrence rate of 10-25%, with less morbidity and mortality as compared to open surgery. On the other hand, treatment of complex liver cysts and hydatid cysts by laparoscopy is not considered a standard approach.
  
  
  CONCLUSIONS
  The laparoscopic approach in uncomplicated but symptomatic liver cysts is effective, with low morbidity and mortality. Additional omentoplasty or oversewing appears to reduce the recurrence rate.
