To compare the clinical efficacy of LC plus LCBDE and ERCP/EST followed by LC in treatment of concomitant gallbladder stones and common bile duct stones in the elderly patients.

The clinical data of 80 patients of concomitant gallbladder stones and common bile duct stones treated with minimally invasive surgical treatment in our hospital from November 2015 to October 2017, were retrospectively analyzed. Of the patients, 40 cases received LC plus LCBDE (LCBDE+ LC group), and 40 cases underwent ERCP followed by LC (ERCP/EST+ LC group). Research data was analyzed by SPSS 19.0 statistical software, the clinical data were shown as (±s), and compared with independent t test, the incidence of complication such as the residual stone rate and postoperative complication rate were compared with χ² test, and P<0.05 was regarded to be statistically significant.

In LC+ LCBDE group versus ERCP/EST+ LC group, the surgical success rate (95.0% vs. 90.0%) and incidence of postoperative complications (7.5% vs. 10.0%) showed no significant difference(P>0.05), but the hospitalization cost was significantly decreased (P<0.05) and length of hospital stay was significantly shortened in the LC+ LCBDE group (P<0.05). The residual stone rate showed no significant difference between the two groups(P>0.05). Both groups were followed up for 3 to 24 months; the incidence of stone recurrence and biliary tract infections showed no significant difference between the two groups.

The two types of operation are both safe and effective. It is suggested that the clinical practice should be selected and applied in accordance with the actual condition of the elderly patients.
