目的 分析消化道改道患者通过气囊辅助内镜行经内镜逆行胰胆管造影(ERCP)的疗效和安全性.方法 收集2016年4月-2017年10月陆军总医院收治的消化道改道术后行气囊辅助内镜ERCP患者12例(4例胆肠吻合术后,8例胰十二指肠切除术后),4例患者采用双气囊小肠镜,8例患者采用单气囊小肠镜.回顾性分析治疗结果及并发症和术后转归情况.结果 10例患者完成气囊辅助内镜ERCP,总体成功率为83.3%,2例患者系单纯性吻合口狭窄,8例在狭窄的基础上合并肝内胆管结石.2例未完成的患者中1例因胆肠吻合口极度狭窄,导丝未能进入胆管内;1例因R-Y肠肠吻合口角度太小,镜身和套管无法进入输入袢.术后发生黄疸1例,消化道穿孔1例,并发症发生率为16.7%,均经内科保守治疗后痊愈.结论 气囊辅助内镜ERCP安全性良好,疗效确切,与传统ERCP相比,成功率较低,有独特的并发症.“,”Objective To investigate the clinical effect and safety of balloon -assisted enteroscopy combined with endoscopic retrograde cholangiopancreatography(ERCP)in patients with altered gastrointestinal anatomy. Methods A total of 12 patients who were admitted to General Hospital of Beijing Military Region from April 2016 to October 2017 and underwent balloon-assisted ERCP after surgical alteration of gastrointestinal anatomy were enrolled,among whom 4 underwent choledochoenterostomy and 8 underwent pancreaticoduodenectomy. Double-balloon enteroscopy was performed for 4 patients and single-balloon enteroscopy was performed for 8 patients. A retrospective a-nalysis was performed for treatment outcome,complications,and prognosis. Results A total of 10 patients underwent balloon -assisted ERCP successfully,resulting in an overall success rate of 83.3%,and among these patients,2 had simple anastomotic stenosis and 8 had anastomotic stenosis and intrahepatic bile duct stones. Among the two patients who did not complete ERCP,one had severe anastomotic ste-nosis which prevented the guide wire from entering the bile duct,and the other patient had a small angle of R-Y intestinal anastomosis which prevented the lens and the cannula from entering the afferent loop. After surgery,one patient experienced jaundice and one experi-enced perforation of the gastrointestinal tract,resulting in an incidence rate of complications of 16.7%,and both patients were cured after conservative treatment. Conclusion Balloon-assisted ERCP has good safety and a marked clinical effect with unique complications,as well as a lower success rate than conventional ERCP.
