Endoscopic retrograde cholangiopancreatography through a gastric stoma using an ultrathin endoscope: a novel approach

Because a transoral or transnasal approach is essential to the performance of endoscopic retrograde cholangiopancreatography (ERCP) [1], difficulties are often encountered in complicated cases when either approach is problematic, including in patients who have suffered a cerebrovascular accident. In such patients percutaneous endoscopic gastrostomy (PEG) has often previously been carried out for long-term nutritional management. Here we describe the successful performance of ERCP through the gastric stoma using an ultrathin forward-viewing endoscope (EG530N5; Fujinon-Toshiba, Tokyo, Japan).
