title: Utility of endoscopic retrograde cholangiopancreatography on biliopancreatic diseases in patients with Billroth II-reconstructed stomach.
abstract: OBJECTIVE
  To examine the utility of endoscopic retrograde cholangiopancreatography (ERCP) on biliopancreatic diseases in the patients with Billroth II-reconstructed stomach.
  
  
  METHODS
  For 26 cases of biliopancreatic diseases in patients with Billroth II-reconstructed stomach, ERCP was conducted using a straight-view scope or a retrograde oblique-viewing endoscope. All the cases were patients aiming at selective insertion into the bile duct. One patient aimed at diagnosis, and 25 patients aimed at treatment. The cases in which the endoscope reached the duodenal papilla and anastomosis, and insertion into the bile duct became possible, were considered successful.
  
  
  RESULTS
  The rate of reaching the duodenal papilla and anastomosis was 84.7% (22/26 patients). Among the cases without reaching the duodenal papilla and anastomosis, there were 2 in which the endoscope did not pass due to tumor-induced duodenal infiltration. In 1 case, the fiber did not reach the duodenal papilla due to long afferent loop. The success rate of insertion into the bile duct in patients in which the endoscope reached the duodenal papilla and anastomosis was 90.9% (20/22 patients), and the success rate of procedures including treatment was 86.3% (19/22 patients). After treatment, mild cholangitis was observed in 1 patient (4.5%, 1/22 patients) but relieved conservatively. No other accidental symptom was observed.
  
  
  CONCLUSIONS
  It was considered that the ERCP for biliopancreatic diseases in patients with Billroth II-reconstructed stomach will become a less invasive, safe and useful examination and treatment approach.
