Abstract: Objective The purpose of this study was to investigate the combination of endoscopic sphincterotomy (EST) and endoscopic papillary balloon dilation (EPBD) in treatment of patients with non-expansive extrahepatic bile duct stones. Methods The clinical data of 120 patients with non-expansive extrahepatic bile duct stones were admitted to the Department of Hepatobiliary Surgery in our hospital between July 2017 and May 2019, and were randomly divided into control (n=60) and observation group (n=60), underwent EST or EST and EPBD combination surgery. Results 7 days after the operation, the white blood cell (WBC) counts in the observation group was (7.8±1.4) ×109/L, not statistically significantly different as compared to (7.6±1.2) ×109/L in the control (P>0.05), serum cyclooxygenase-2 level in the observation group was (45.3±11.7) ng/mL, not much different to (49.6±15.2) ng/mL, blood procalcitonin (PCT) level was (0.4±0.3) g/L, not significantly different to (0.4±0.2) g/L, serum C-reactive protein (CRP) level was (8.7±2.9) mg/L, not significantly different to (8.4±3.2) mg/L, serum tumor necrosis factor-α (TNF-α) level was (0.5±0.2) ng/mL, not significantly different to (0.5±0.2) ng/mL, blood amylase level was (60.1±16.7) U/L, not significantly different to (58.7±15.3) U/L in the control (P>0.05); the total incidence of complications in the observation group was 25.0%, not statistically significantly different compared with 31.7% (P>0.05) in the control; the successful rate of primary stone removal in the observation group was 98.3%, significantly higher than 86.7% in the control, and the mechanical gravel rate was 5.0% and the stone recurrence rate was 3.3%, both significantly lower than 16.7% and 15.0%, respectively, (P<0.05) in the EST-treated patients.Conclusion The combination of EST and EPBD in the treatment of patients with non-dilated extrahepatic bile duct stones has a higher successful rate of one-step stone extraction, with less postoperative stone recurrence, which warrants further clinical investigation.
