Contrastive Study for Minimally Invasive Cholecystolithotomy With Gallbladder Reservation and Laparoscopic Cholecystectomy

All the Phases Study Will be Operated by the Department of Hepatobiliary Surgery, The Affiliated Hospital of Guiyang Medical College

To explore the therapeutic effects for treatment of cholecystolithiasis by minimally invasive cholecystolithotomy with gallbladder reservation and laparoscopic cholecystectomy. Method： patients with cholecystolithiasis who received minimally invasive Cholecystolithotomy with gallbladder reservation and patients with cholecystolithiasis who received laparoscopic cholecystectomy(LC) in The Affiliated Hospital of Guiyang Medical College from May 2011 to December 2013. Patients who received minimally invasive cholecystolithotomy with gallbladder reservation as trial group, patients who received LC as control group.the overall follow-up period is 1 year. Then the investigators statistically analyze improvement of cholecystolithiasis symptoms in every group, thickness of gall bladder wall, the gallbladder function and the rate of the recurrence of cholesterol gallstone in trial group.

The investigators Prospect： Minimally invasive cholecystolithotomy with gallbladder reservation is meaningful for recovering the function of gallbladder.
