摘要目的 评价使用双腔前视胃镜对毕Ⅱ式胃空肠吻合术后胆胰疾病患者进行经内镜逆行胰胆管造影术(ERCP)治疗的疗效及安全性.方法 回顾性总结46例使用双腔前视胃镜进行ERCP治疗的毕Ⅱ式胃空肠吻合术后胆胰疾病患者的临床资料,统计十二指肠乳头插管成功率、并发症发生情况和治疗情况.结果 十二指肠乳头插管成功率为82.6％ (38/46),8例失败,其中6例因双腔前视胃镜无法进入输入袢找到十二指肠乳头而失败,2例因乳头插管困难而失败.38例插管成功者中,31例胆管结石者均成功取出结石,4例胆总管下端恶性梗阻者均成功置入胆管金属支架,3例十二指肠乳头良性狭窄者经气囊扩张后均成功置入鼻胆引流管;所有患者术后恢复良好,无一例发生出血、穿孔和术后胰腺炎等严重并发症.结论 使用双腔前视胃镜对毕Ⅱ式胃空肠吻合术后胆胰疾病患者进行ERCP治疗,插管成功率较高,可顺利完成后续ERCP相关治疗,并且不会明显增加并发症发生率,具有较好的临床应用价值.

abstractsObjective To evaluate the therapeutic effect and safety of forward-viewing,doublechannel endoscope in the process of ERCP in patients with bile duct diseases after Billroth-Ⅱ gastroenterostomy.Methods ERCP was applied to 46 patients with bile duct diseases using forward-viewing,doublechannel endoscope.All patients had the history of Billroth-Ⅱ gastroenterostomy.The success rate of selective cannulation,complication rate and the outcome of all the patients were recorded.Results The procedure succeeded in 38 patients with a success rate of 82.6％,and failed in 8.Of all the failing cases,the afferent loop couldn't be accessed in 6,failure in biliary cannulation in 2.Of 38 successful cases,bile duct stones were successfully removed in 31,metal stents placed for malignant bile duct obstruction in 4,and endoscopic balloon dilation for benign common bile duct stricture in 3.All patients recovered without complications of perforation,delayed bleeding or pancreatitis.Conclusion For patients with history of Billroth-Ⅱgastroenterostomy,ERCP with forward-viewing,double-channel endoscope yields to a higher success rate and lower complication rate.
