Evaluation of clinical therapeutic effects of choledochofiberscope in the treatment of biliary calculi

Objective To investigate the clinical effect of choledochofiberscope in the treatment of biliary calculi and its reasonable choice. Methods Retrospective analysis of 300 cases of biliary stones in a affiliated hospital of Anhui Medical University from 2008 to 2012 was conducted to analyze the success rate, time and postoperative complications. Results 100 case of simple surgery, stones take net rate was 65.00%, 200 cases of biliary endoscopy group, which combined choledochoscope with intraoperative treatment group stones to take net rate was 91.96%, postoperative choledochoscope stones treatment group was 96.60% of net take, choledochofiberscope was significantly greater than the simple surgery group, the difference was statistically significant (χ²=23.35,P<0.001), the difference of intraoperative and postoperative choledochofiberscope stone net rate was not statistically significant (χ²=1.87,P=0.171); the difference of intraoperative and postoperative biliary endoscopy take stone time was not statistically significant (t=0.67,P=0.263); the difference of intraoperative and postoperative choledochofiberscope complication rate was not statistically significant (χ²=0.61,P=0.434). Conclusions It is demonstrated that choledochoscope application reduced the calculi recurrence rate, intraoperative and postoperative choledochoscope is an ideal way of dealing with stones in the processing of stone, we need to make reasonable choice based on patient condition, not only emphasizes the role of intraoperative choledochoscope but negelect the effect of postoperative choledochoscope.
