title: Laparoscopic Management of Mirizzi Syndrome Without Dissection of Calot's Triangle.
abstract: BACKGROUND
  Mirizzi syndrome (MS) is a rare complication of cholecystolithiasis that causes compacted gallstones and is often accompanied by severe inflammation of Calot's triangle. This study compared the use of laparoscopic surgery for MS without dissection of Calot's triangle with routine laparoscopic cholecystectomy (LC).
  
  
  METHODS
  A total of 411 consecutive patients underwent laparoscopic surgery for benign gallbladder (GB) disease between January 2013 and December 2014. Five patients underwent laparoscopic surgery for MS (MS group) while 406 underwent routine LC (LC group). The preoperative diagnosis was accurate in all patients in the MS group.
  
  
  RESULTS
  The LC and MS groups did not differ significantly in the operation time, blood loss, length of hospital stay, or incidence of GB carcinoma. In addition, conversion, bile duct injury, and bile leak rate were not different between the two groups.
  
  
  CONCLUSIONS
  This study demonstrates the safety of laparoscopic partial cholecystectomy without dissection of Calot's triangle for MS. In addition, an accurate preoperative diagnosis is critical in surgical decision making to avoid injury to the bile duct.
