摘要目的：探讨运用十二指肠镜对毕Ⅱ式胃切除术后患者行 ERCP 治疗的有效性和安全性。方法回顾性分析2008年1月至2014年5月行 ERCP 治疗的98例毕Ⅱ术后患者（包括7例毕Ⅱ式胃切除术＋Braun 吻合）的病历资料。结果98例患者共完成111次 ERCP 操作，总的 ERCP 成功率为75.7％（84／111），内镜到达乳头的成功率为82.0％（91／111），选择性插管成功率为92.3％（84／91）。对于插管成功的患者，治疗性操作成功率为100.0％（84／84）。全组并发症发生率为4.5％（5／111），包括3例轻度胰腺炎和2例胆道感染。结论采用十二指肠镜对毕Ⅱ式术后患者行 ERCP治疗是安全有效的，对内镜能到达十二指肠乳头者，其插管成功率和治疗成功率均较高。

abstractsObjective To evaluate the efficacy and safety of endoscopic retrograde cholangiopancre-atography (ERCP)by using a duodenoscope in patients with prior Billroth Ⅱ gastrectomy.Methods Data of 98 patients(including 7 who underwent Billroth Ⅱand Braun)with prior Billroth Ⅱ gastrectomy who un-derwent ERCP from January 2008 to May 2014 at Endoscopy Center of Ruijin Hospital were retrospectively studied.Results A total of 98 patients accepted 111 ERCP procedures,the overall success rate was 75.7%(84 /111).The success rate of accessing Vater′s papilla was 82.0%(91 /111)and the selective can-nulations success rate was 92.3%(84 /91).In the cases of successful access,therapeutic procedures were achieved in 100.0%(84 /84)of all patients.The overall rate of complications was 4.5%(5 /111),with mild post-procedure pancreatitis occurring in 3 cases,cholangitis in 2 cases,respectively.Conclusion ERCP u-sing a duodenoscope can be safely and effectively performed in patients with prior Billroth Ⅱ gastrectomy with high cannulation and treatment success rates.
