Abstract

Radiological intervention via percutaneous transhepatic biliary drainage and endoscopic intervention via endoscopic retrograde cholangiopancreatography are the preferred methods to treat liver transplantation (LT)-associated benign biliary stricture (BBS). Magnetic compression anastomosis (MCA) can be applied to reconstruct a refractory or completely obstructing BBS that cannot be resolved with conventional methods. The MCA procedure is divided into four steps: tract formation for magnet delivery, approximation of magnets, removal of the approximated magnets, and maintenance and removal of the internal catheter. We present a patient with BBS, following dual-graft living-donor LT, which was successfully recanalized via MCA with detailed review of technical procedures. In the present case, MCA facilitated the passing of the guidewire through the completely occluded BBS for conventional treatment via long-term endobiliary stenting. MCA is a nonsurgical alternative for treating severe or completely obstructing BBSs that are refractory to conventional endoscopic or percutaneous treatment methods.
