Risk factors related to choledocholithiasis in gallstone patients / 中华普通外科杂志

ABSTRACT

Objective:To investigate the risk factors related to choledocholithiasis in gallstone patients.Methods:The clinical data of 140 patients with gallstones or gallstones complicated with choledocholithiasis treated at our hospital from Jan 2017 to Dec 2019 were analyzed retrospectively.Results:The results showed gallstones≥ 10 mm (χ 2=7.896, P=0.019), parapapillary diverticulum (χ 2=10.849, P=0.013), the number of gallstones (single vs. multiple) (χ 2=9.760, P=0.080), age ( t=2.767, P=0.006), diameter of common bile duct ( t=8.068, P=0.000), total bilirubin level ( t=2.372, P=0.019), alkaline phosphatase ( t=2.448, P=0.016), significantly related to the formation of common bile duct stones. Logistic regression analysis showed that gallstone ≥ 10 mm, common bile duct dilatation, parapapillary diverticulum and multiple gallstones were all independent risk factors for choledocholithiasis in gallstone patients. Conclusion:A variety of risk factors were responsible for the formation of choledocholithiasis in gallstone patients.
