1, Methods patients with choledochotomy and T-tube drainage were selected in the study.

2, Objective To explore the proper time of griping T-tube and the method which can reduce the loss of the bile after choledochotomy with exploration.

3, Methods:analysis and sum up the result with a bile duct detection technique after the operation of 48 choledochotomy.

4, Common bile duct laceration was noted at laparotomy and was successfully treated by choledochotomy and T-tube stent.

5, Objective To study the feasibility of primary closure of laparoscopic choledochotomy combined with cystic duct tube.

6, Objective To explore the feasibility and minimally invasive value of laparoscopic choledochotomy with exploration and choledocholithotomy and primary suture of common bile duct.

7, To explore indications, surgical characteristics, prevention and management of biliary complications of T-tube drainage (TD) and primary closure (PC) during laparoscopic choledochotomy (LCD).

8, Objective To explore risk factors of bile leakage after primary ductal closure following choledochotomy .

9, Objective To explore a new way of enteral nutrition for the after choledochotomy.

10, Objective To study the effect of laparoscopic common bile duct exploration via choledochotomy and T tube drainage.

11, ObjectivesTo explore the feasibility and efficacy of primary suture after choledochotomy for stone removal and exploration.

12, Conclusion It is a new way to solve enteral nutrition problem for the after choledochotomy.

13, Methods 37 cases who had taken relative exploring sign underwent cholangiography before choledochotomy,(http:///choledochotomy.html) and the negative patients would not take choledochus exploration.

14, Methods From January 2001 to June 2006, 9 cases with bile leakage after choledochotomy with exploration and T tube drainage were analyzed retrospectively.

15, Metheods Laparoscopic exploration of common bile duct with choledochoscopy via choledochotomy was performed in 105 patients, T tube was placed in all patients with laparoscopic suturing technique.
