ERCP for patients who have undergone Billroth Ⅱ gastroenterostomy and Braun anastomosis

Endoscopic retrograde cholangiopancreatography(ERCP)is efficacious in patients who have undergone Billroth Ⅱ gastroenterostomies,but the success rate decreases in patients who also have experienced Braun anastomoses.There are currently no reports describing the preferred enterography route for cannulation in these patients.We first review the patient’s previous surgery records,which most often indicate that the efferent loop is at the greater curvature of the stomach.We recommend extending the duodenoscope along the greater curvature of the stomach and then advancing it through the"lower entrance"at the site of the gastrojejunal anastomosis,along the efferent loop,and through the"middle entrance"at the site of the Braun anastomosis to reach the papilla of Vater.Ten patients who had each undergone BillrothⅡgastroenterostomy and Braun anastomosis between January 2009 and December 2011 were included in our study.The overall success rate of enterography was 90% for the patients who had undergone BillrothⅡgastroenterostomy and Braun anastomosis,and the therapeutic success rate was 80%.We believe that this enterography route for ERCP is optimal for a patient who has had BillrothⅡgastroenterostomy and Braun anastomosis and helps to increase the success rate of the procedure.
