Biliary tract complications after liver transplantation remain a major therapeutic issue significantly affecting graft and patient survival [1]. Strictures of the bile duct account for about 40 % of biliary complications after liver transplantation [2]. Today, endoscopic retrograde cholangiography (ERC) has widely replaced surgery and percutaneous techniques as the treatment of choice for such patients [3]. However, highly fibrotic strictures of the anastomotic region frequently preclude passage of the guidewire. In these cases, percutaneous transhepatic cholangiography (PTC), endoscopic ultrasound-guided biliary drainage, or indication for resection of the stenosis-bearing extrahepatic biliary segment with subsequent biliodigestive anastomosis are applied, all of which are associated with increased morbidity.

We present here three patients with late fibrotic strictures of the anastomotic region after deceased donor liver transplantation ([Table 1]). ERC revealed high grade stenosis that was impossible to pass despite various ERC maneuvers, including use of hydrophilic guidewires, occlusion balloons, and rotatable sphincterotome ([Fig. 1]). Using single-operator cholangioscopy (SpyGlass DS direct visualization system; Boston Scientific), the pin-sized orifice could be identified in all cases ([Fig. 2]). Only direct visual guidance allowed placement of a 0.025-inch hydrophilic guidewire through the stricture in two patients ([Fig. 3]). In one patient, pre-dilation of the stricture by means of biopsy forceps allowed subsequent guidewire placement ([Fig. 2 b]). Gradual mechanical dilation and stent placement were achieved in all three cases, avoiding alternative more invasive and riskier procedures. Consequently, direct cholangioscopy resulted in a therapeutic success in all three cases after failure of standard ERC.

Qualität:

From our experience we conclude that single-operator cholangioscopy (SpyGlass) seems to be a useful therapeutic option in patients with highly fibrotic strictures post-liver transplantation. No procedure-related complication occurred. No further interventions, in particular PTC or surgery, with associated morbidity were needed.
