To explore the clinical effect of different sequential sequences of ERCP combined with ESTand LC in the elderly patients with gallbladder and choledocholithiasis.

A total of 114 elderly patients diagnosed as cholecystolithiasis with choledocholithiasis treated in our hospital were selected and divided into Group A (57 cases) and group B (57 cases) by computer random method. ERCP+ EST operation before LC and ERCP+ EST operation after LC operation were respectively adopted by group A and group B. The data of intraoperative, postoperative conditions and postoperative complications were observed and compared. Stata 13.2 statistical software package was used for data analysis. The measurement data of age, BMI and stone size were compared with independent sample t test, the sex composition ratio, postoperative complication and other counting data were compared with the Chi square.

The interval of operation in group A was significantly lower than that in group B (P<0.05); There was no significant difference in success rate of calculus removing, bleeding volume, operation time, hospitalization time and exhaust time between the two groups (P>0.05). The total complication rate of group A was 10.5% (6/57), and the total complication rate in group B was 26.3% (15/57). There was a significant difference between two groups (χ²= 4.728, P= 0.030). The incidence of biliary tract infection and total complications in B group were significantly higher than those in group A (P<0.05).

ERCP+ EST operation before LC can reduce the operative interval time, reduce the incidence rate of iatrogenic bile duct injury, postoperative biliary tract infection and the total complications, and is worthy of clinical promotion.
