ABSTRACT
Objective To study the effectiveness and safety of different endoscopic papillary balloon dilation time in treatment of common bile duct stones. Methods 45 patients with common bile duct stones received ERCP treat﹣ment, and they were randomly divided into short-term and long-term balloon dilatation group, then compared opera﹣tive time, intraoperative and postoperative complication rate, hospitalization days and the total cost of hospitalization between the two groups. Results Short-term group included 22 people, the long term group included 23 people, there were no significant difference in stones' size, number and diameter of common bile duct between the two groups (P> 0.05), however, the success rate of surgery, time of stones' extraction, intraoperative complications and postoperative fistula were significant differences (P<0.05). Conclusion Long-term balloon dilation during ERCP for treatment of common bile duct stones can improve the success rate of stone removal and reduce complications.
