Abstract
Magnetic compression anastomosis (MCA) is a minimally invasive method of performing choledochocholedochostomy without surgery in patients with biliary stricture or obstruction. We describe a successful case involving magnetic compression duct-to-duct biliary reconstruction in right-lobe living donor liver transplantation (RL-LDLT). Endoscopically, a samarium-cobalt (Sm-Co) rare-earth magnet was placed at the superior site of obstruction via the percutaneous transhepatic biliary drainage route, and another Sm-Co magnet was also placed at the inferior site of obstruction with the aid of an endoscope. MCA techniques enabled complete anastomosis without procedure-related complications. In conclusion, the MCA technique is a revolutionary method of performing choledochocholedochostomy in patients with biliary obstruction after LDLT.
