1, There was no choledochus injury and death case.

2, Patients of two groups did choledochus drainage and peritoneal drainage in the same time.

3, Results The cases of positive gallbladder mucosa and choledochus bile were 13 (27.1%) and 31(64.6%) respectively. The cases of double positivity were 12 (25.0%).

4, Objective To evaluate the means of preventing iatrogenic choledochus injury in mini - cholecystectomy( MC ).

5, Methods Giving statistical analysis to 733 cases of choledochus exploration and 16 cases of choleperitoneum after the extraction of T-tube,(http:///choledochus.html) and research the history and complications.

6, Objective : To investigate if tissue harmonic imaging ( THI ) can improve the image quality of choledochus - pancreatic disease.

7, Objective To study the relationship between the bacterial spectrum difference of gallbladder mucosa and choledochus bile and clinical prognosis of gallstone pancreatitis.

8, The parameters above measured in different groups including control group, portal hypertension group, choledochus obstruction group, and malignant tumor group were compared.

9, Objective To discuss the diagnosis and prevention of iatrogenic choledochus injury during operation.

10, Results: In the same plane, the sensitivity of showing ductus hepaticus and ductus hepaticus communis, ductus choledochus with MR oblique-coronal T2WI was superior to conventional MR coronal T2WI.

11, Method Statistics and analyse the quantity, type and reason of iatrogenic choledochus injury a year in 29771 cases of mini - cholecystectomy from 1991.1 to 2005.12.

12, Results:10cases(62.5%)of iatrogenic bile duct injuries were caused by cholecystectomy, 4(25.0%)by cholecystectomy and choledochus exploration, 2(12.5%)by other abdominal operation.

13, METHODS:Experiments were carried out in conventional mice models of gastric ulcer and diarrhea, and in rats with choledochus catheterization.

14, Results: 12 cases succeed, while a little calculus was found in one patients choledochus after operation, and was taken out using choledochoscope.

15, Abstract Objective To summarize the experience of Laparoscopic choledocholithotomy for thin choledochus.

16, Cholecyst lies in right endite, bile duct and hepatic duct converge choledochus, hepatic duct is compiled by small hepatic duct of every lobe.

17, Objective To evaluate the feasibility of exploration of ductus choledochus for choledocholelithes by choledochofiberoscope via cystic duct.

18, Objective To study the applied value of choledochofiberscope on the exploratory operation of choledochus through cystic duct.

19, Methods 37 cases who had taken relative exploring sign underwent cholangiography before choledochotomy, and the negative patients would not take choledochus exploration.
