Biliary hemorrhage after removal of an expandable metallic stent during liver transplantation

The self-expandable metallic stent (SEMS) has become a common device for palliative treatment of malignant biliary obstructions or benign strictures. Despite the ease of placement of SEMSs, their removal has been reported to be very difficult. Here, we report a case with primary sclerosing cholangitis who developed massive hemorrhage after intraoperative removal of a SEMS. Possible living donor liver transplantation (LT) was considered for a 49-year-old female with primary sclerosing cholangitis. However, her general condition did not meet the criteria for LT; therefore, she was referred back to her primary physician. Two years later, she developed jaundice, and her primary physician placed multiple SEMSs, 1 of which was placed across the papilla of Vater. She was evaluated rapidly, and underwent living donor LT. During the operation, the common bile duct was examined and an incision was made. A stent was found firmly embedded in the bile duct. Each wire of the SEMS was pinched and then successfully pulled out 1 by 1. Finally, all parts of the SEMS were removed. Before creating the Roux-en-Y limb, hemorrhage from the remnant bile duct was confirmed by examination of the duodenum and bile duct stump. The bile duct was sewn internally with monofilament stitches and compressed for 10 minutes. Finally, hemostasis was brought about and transplantation was completed successfully. Despite some reports regarding successful endoscopic removal of SEMSs, its removal in patients with portal hypertension coagulopathy is risky. SEMSs should not be placed in patients who are candidates for LT.
