title: An alternative approach to the inaccessible intradiverticular papilla.
abstract: BACKGROUND
  In patients with a narrow-necked juxtapapillary diverticulum the endoscopic cannulation of the papilla of Vater and the subsequent biliary therapy is sometimes impossible.
  
  
  METHODS
  Three patients referred for endoscopic retrograde cholangiography and stone extraction were included. Earlier attempts to cannulate failed because visual control was impeded by narrow-necked juxtapapillary diverticula with the papilla located in the fundus. Endoscopic balloon dilation of the narrow diverticular neck, using a 15-mm stone retrieval balloon, was carried out.
  
  
  RESULTS
  In all three cases the papillary orifice was readily brought into view after balloon dilation of the diverticular opening. Subsequent endoscopic treatment to the bile duct was successful without any complications.
  
  
  CONCLUSIONS
  Balloon dilation of a narrow-necked juxtapapillary diverticulum is a safe and easy procedure, which facilitates both cannulation of the papilla and subsequent biliary endoscopic treatment.
