title: [The analysis of follow-up results of 612 cases of cholecystolithiasis treated with the minimal invasive operation with gallbladder preserved via choledochoscopy].
abstract: OBJECTIVE
  To discuss the feasibility of the operation of minimal invasive with gallbladder preserved via choledochoscopy.
  
  
  METHODS
  From February 1992 to June 2006, there were 760 patients who underwent cholecystolithiasis treated with the minimal invasive operation with gallbladder preserved via choledochoscopy, among which there were 428 males and 332 females, aged from 18 to 81 years old. All cases were diagnosed by ultrasonography and their gallbladder functions were proved normal by the examination of oral cholecystography or ECT before operation. In the operation gallstones were removed from gallbladder completely.
  
  
  RESULTS
  There were 612 cases who were followed up for 1-15 years and the follow-up rate was 80.5%. All patients recovered well after operation. The post-operation rate of recurrence of gallstone was 0.49%, 4.39%, 5.83%, 6.60%, 7.21% and 8.38% within the first year, the second year, the third year, the fifth year, the seventh year and the ninth year respectively, rate of recurrence of gallstone were 10.11% within both the tenth and the fifteenth year.
  
  
  CONCLUSIONS
  The minimal invasive operation with gallbladder preserved via choledochoscopy is effective to cholecystolithiasis patients whose gallbladder function is normal. It is a feasible operation that preserves the normal functional gallbladder and improves the patients' life quality.
