摘要目的：探讨针状刀乳头预切开术在内镜下逆行胰胆管造影术（ ERCP ）中选择性胆管插管困难时的作用及安全性。方法回顾性分析104例（针状刀组）行针状刀乳头预切开术患者的临床资料，观察预切开的效果和近期并发症，并与ERCP同期常规选择性插管成功1326例（常规组）做比较。结果全组104例行针状刀预切开后，选择性胆管插管成功97例，成功率93．3％。术后并发症8例（7．7％），包括出血4例，轻型胰腺炎2例，胆道感染2例；ERCP同期常规选择性插管成功1326例，并发症98例（7．4％）；针状刀预切开组与同期常规选择性插管成功组患者的并发症发生率差异无统计学意义（χ2＝0．055，P＞0．05）。结论在ERCP胆管插管困难时采用针状刀乳头括约肌预切开术是一种安全有效的方法，有效地提高ERCP的成功率，值得临床广泛应用。

abstractsObjective To investigate the effects and safety of needle?knife precut papillotomy in diffi?cult common bile duct cannulation of endoscopic retrograde pancreatic duct radiography ( ERCP ) . Methods The data of 104 cases treated with needle?knife precut papillotomy were retrospectively analyzed. The effect of pre incision and short?term complications were observed,and compared with 1326 cases( conventional group) of con?ventional selective intubation in the same period of ERCP. Results Successful cannulation of the bile duct was achieved in 97 of 104 patients who underwent needle?knife precut papillotomy, the total success rate was a?chieved in 93. 3%. The complications of needle?knife precut papillotomy occurred in 8 patients(7. 7%),inclu?ding mild bleeding in 4 cases,mild pancreatitis in 2 cases and billiary infection in 2 cases. There were 1326 ca?ses conventional selective intubation in the same period of ERCP,and 98 cases(7. 4%) with complication. There was no significant difference in the incidence of complications between the needle knife cut group and the con?ventional selective intubation group(χ2=0. 055,P>0. 05 ) . Conclusion In case of difficult common bile duct cannulation of ERCP,needle?knife precut sphincterotomy surgery can be safely and effectively catch the high ?ERCP the success of treatment,is worthy of wider application.
