Abstract:Objective To investigate the effectiveness of Danning tablets in prevention of gallstone recurrence after choledochoscopic gallbladder-preserving cholecystolithotomy (CGPC), and the difference between Danning tablets and tauroursodeoxycholic acid (TUDCA).Methods From November 2016 to January 2020, 1,868 patients were studied following CGPC. Patients were divided into two cohorts according to the type of gallstones. Patients in cohort A had cholesterol stone removal via CGPC, compared to cohort B with bile pigment stone removal by the same treatment. Patients in each cohort were randomly divided into two groups, namely DN and TU. Group DN were prescirbed Danning tablets (1.8 g/time, 3 times/d), while group TU took TUDCA (500 mg/time, once a day). Both groups received treatment for 180 days and were followed up for 36 months. The frequency of recurrence of gallstones and the thickness of the gallbladder wall were recorded.Results By comparing the effects of Danning tablets and TUCDA, the findings indicate that in cohort A, there was no significant difference in the rate of gallstone recurrence between group A-DN and group A-TU. In cohort B, the rate of gallstone recurrence in group B-DN was significantly lower than in group B-TU. In both cohorts, meanwhile, the average thickness of the gallbladder walls was significantly thinner in the two DN groups than in the TU groups half a year after CGPC.Conclusion The results show that prescribing Danning tablets after CGPC can help relieve postoperative gallbladder inflammation and effectively reduce the recurrence rate of gallstones. For gallstones dominated by bile pigments, Danning Tablet is more effective than TUDCA in preventing the recurrence of gallstones after CGPC.
