title: ERCP for intradiverticular papilla: two-devices-in-one-channel method. Endoscopic Retrograde Cholangiopancreatography.
abstract: BACKGROUND
  The prevalence of biliopancreatic disorders is high in patients with periampullary diverticula. However, endoscopic retrograde cholangiopancreatography (ERCP) in patients with the papilla deep inside duodenal diverticula is difficult.
  
  
  METHODS
  Two patients were included in this study, each with the papilla deep inside a diverticulum and in whom an initial ERCP was unsuccessful. A biopsy forceps to pinch the duodenal mucosa distal to the papilla and pull the papilla out of the diverticulum and a cannula were inserted into the working channel of a duodenoscope together (the two-devices-in-one-channel method). With coordination of the two instruments, cannulation of the bile duct was attempted.
  
  
  RESULTS
  In both patients ERCP was successful using this procedure and no complications followed.
  
  
  CONCLUSIONS
  The two-devices-in-one-channel method is useful when performing ERCP in patients with the papilla inside juxtapapillary diverticula.
