title: Evaluation and Comparison of the Early Outcomes of Open and Laparoscopic Surgery of Liver Hydatid Cyst.
abstract: OBJECTIVE
  Surgery is the mainstay for treatment of liver hydatid cyst. Different surgical procedures have been suggested, but it is important to select the most appropriate treatment to obtain the best results with the lowest rate of recurrence and minimal morbidity and mortality. The aim of this study was to evaluate the early outcomes of open and laparoscopic surgery of hydatidosis.
  
  
  METHODS
  In this study, 75 patients with uncomplicated liver hydatid cyst were assigned prospectively to either groups of laparoscopic surgery (37, 50.68%) or open procedure (36, 49.32%) during the period of 2007 to 2012. Conversion to open surgery was required in 2 patients (2.67%), who were excluded from the study. Patients were followed for about 17.86±17.64 months.
  
  
  RESULTS
  Participants included 73 patients: 49 (67.12%) female and 24 (32.88%) male patients, with the mean age of 38.97±16.48 years. There was no statistically significant difference between the 2 groups with regard to the sex, the occupation, and the mean diameter of the cysts. Bilious staining of the cyst content was observed in 23 (35.94%) patients during surgery, and a maximum diameter of 91 mm was considered as a cut point for predicting postoperative fistula with 69.2% sensitivity and 41.1% specificity. The mean duration of operation, postoperative pain, the hospitalization time, and the time to return to work were significantly lower in the laparoscopic group. Postoperative biliary fistula, cyst cavity infection, and wound infection were not different between the 2 groups.
  
  
  CONCLUSIONS
  Laparoscopic surgery seems to be effective and safe, with low morbidity rates for uncomplicated cysts in accessible segments of the liver.
