ERCP in patients with prior Billroth II gastrectomy

Objective To evaluate the efficacy and safety of endoscopic retrograde cholangiopancreatography (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 underwent 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 cannulations 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 using a duodenoscope can be safely and effectively performed in patients with prior Billroth Ⅱ gastrectomy with high cannulation and treatment success rates.
