Single Balloon Enteroscopy Assisted Endoscopic Retrograde Cholangiopancreatography and Precut Sphincterotomy for Treatment of Retained Common Bile Duct Stone in Billroth II Gastrectomy Patients
Abstract
Performing Endoscopic Retrograde Cholangiopancreaticography (ERCP) with a standard duodenoscope in a patient having a surgically altered anatomy such as Billroth II gastrectomy or Roux-en-Y anastomosis can be technically challenging and sometimes impossible. Thus ERCP has a low success rate in these patients.1-3 It may be easier to identify the afferent limb using end-viewing endoscope than sideviewing endoscope.4 Single-balloon enteroscopy (SBE) may improve the ability to identify the biliary and pancreatic orifice allowing endoscopists to perform intervention.5
