Endoscopic retrograde cholangiopancreatography after Billroth-Ⅱ gastrectomy and its safety

Objective To investigate the safety of endoscopic retrograde cholangiopancreatography(ERCP) after Billroth- Ⅱ gastrectomy.Methods A total of 43 patients who were admitted to our hospital and underwent Billroth-Ⅱ gastrectomy from June 2012 to June 2015 were enrolled and underwent ERCP.Results Of all 43 patients undergoing ERCP,39(90.7%) received successful intubation,2(4.7%) received failed intubation,and 2(4.7%) experienced the complication of digestive tract perforation.Among the 39 patients who underwent ERCP,31(79.5%) were diagnosed with common bile duct stones(3 underwent sphincterotomy and 28 underwent endoscopic papillary balloon dilation to remove stones),6(15.4%) were diagnosed with benign stenosis at the end of bile duct(4 underwent papillary balloon dilation alone and 2 underwent biliary plastic stent implantation),and 1 patient each(2.6%) was diagnosed with ampullary tumor and hepatic portal metastasis of gastric cancer and received implantation of metal and plastic stents,respectively.One patient(2.6%) experienced acute pancreatitis after surgery.Conclusion ERCP is safe and effective in patients after Billroth-Ⅱgastrectomy and holds promise for clinical application.
