Abstract:
Objective To evaluate the therapeutic efficacy and safety of endoscopic sphincterotomy (EST) combined with large balloon dilation for bile duct stones.Methods A total of 83 patients with common bile duct stones were randomly divided into 2 groups to receive standard EST (n =41,EST group) or EST plus large balloon dilation (n =42,EPLBD group),respectively.The number of endoscopic session,operation time,rates of successful complete stone retrieval,mechanical lithotripsy,and procedure related complication were compared between the two groups.Results The rate of early procedure-related complications was similar in 2 groups (9/41 vs.7/42,P ＞0.05),including perforation ( 1/41 vs.0/42,P ＞0.05),bleeding (5/41 vs.2/42,P＞0.05) and pancreatitis (3/41 vs.5/42,P＞0.05).The rate of successful complete stone removal was also similar in 2 groups (39/41 vs.41/42,P ＞ 0.05 ).However,EST group needed more procedure time (38.8 ±4.3 min vs.29.2 ±5.3 min,P ＜0.01 ) and use of mechanical lithotripsy to achieve complete stone removal (9/41 vs.2/42,P ＜ 0.05 ).Only one patient in EPLBD group ( 1/42,2.4％ ) needed a second ERCP to clear bile duct stone,while in EST group,8 patients underwent a second procedure ( 19.5％,P ＜ 0.05 ).Conclusion For endoscopic removal of common bile duct stones,EST combined with larg4e balloon dilation is as safe and effective as EST,while easier in manipulation.
