title: [The effect of methylenum coeruleum in laparoscope cholecystectomy].
abstract: OBJECTIVE
  To help the operator correctly judge in operation the cystic gall duct and choledoch, and eliminate the operation wound.
  
  
  METHODS
  To divide laparoscope cholecystectomy patients with the same weight at the same period into two groups: development group (589 cases) using methylenum coeruleum and conducting cholecysto-puncture visualization during the operation in which colors of cholecyst, cystic gall duct and choledoch turn blue; comparative group (553 cases) using regular laparoscope cholecystectomy.
  
  
  RESULTS
  The two groups differed remarkably in operation time, complication, and transferring rate (P < 0.01).
  
  
  CONCLUSIONS
  Methylenum coeruleum development technology in operation is a kind of visualization to help the operator judge in operation Calot triangular anatomy construction correctly, reduce the operation time obviously, and increase the rate of success.
