Cinical characteristics of small common bile duct stone's spontaneous excretion / 中华普通外科杂志

ABSTRACT

Objective To investigate the excretion probability,clinical characteristics of gallstones with small common bile duct stone.Methods The clinical data of 216 patients were analyzed retrospectively.The relevant clinical characteristics of small common bile duct stone's excretion were analyzed.x2 and Pearson correlation coefficient were used to analyze correlation between small common bile duct stone's excretion and relevant clinical characteristics,multiple logistic regression analysis was performed to identify these excretion related factors.Results Univariate analysis showed that patients of age less than 50 years,female sex,abdominal pain relieved and liver function recovered rapidly in 3 days of treatment,normal or slightly dilated diameter of common bile duct,single or multiple stones located in one place,stones completely located in the common bile duct or completely within the sphincter were more likely to be discharged.Multivariate analysis indicated that rapid relief of abdominal pain,rapid recovery of liver function,single or multiple stones located in one place were independently correlated with small common bile duct stone's excretion.Conclusion Small stones in common bile duct have a high probability of spontaneous removal in patients with gallstones and small common bile duct stone.
