Single balloon enteroscopy for endoscopic retrograde cholangiography in patients with Roux-en-Y hepaticojejunoanastomosis

Figure 1 Schematic image of Roux-en-Y hepaticojejunoanastomosis[22].

Figure 2 Endoscopic image. A: Successful cannulation of a stenotic orifice of the hepaticojejunoanastomosis (HJA) (followed by successful cannulation of adjoining bile ducts); B: Dilation balloon in a deflated form successfully inserted down the guide wire into the area of the stenotic HJA; C: Last phase of a successful endoscopic insertion of a 7 Fr plastic biliary drain into the stenotic HJA and adjoining bile ducts; D: Highly satisfactory final effect of endoscopic treatment of the stenotic HJA (with inserted guide wire).

Figure 3 Endoscopic retrograde cholangiography performed by using single balloon enteroscopy. A: A patient with hepaticojejunoanastomosis (HJA) shows comparatively narrow HJA stenosis with suprastenotic dilation of bile ducts; B: The patient from Figure 3A in whom HJA stenosis was successfully bridged by endoscopic insertion of a 7 Fr plastic biliary stent.
