RESUMO
OBJECTIVE: To investigate the prevention and treatment of biliary complications after orthotopic liver transplantation (OLT). METHODS: OLT was performed in 18 patients with end-stage liver disease, including 6 patients with primary liver cancer. Except 1 patient was infused only through the portal vein, others were infused through the portal vein and hepatic artery of the donor. The biliary tract was reconstructed using choledochocholedostomic anastomosis in 17 patients, and using Roux-en-Y choledochojejunostomic anastomosis in 1 patient. RESULTS: Four patients with biliary complication were found. In one patient, biliary leakage was found around the T-tube on day 14 postoperatively, and disappeared after re-opening of the tube. In one patient undergoing Roux-en-Y choledochojejunostomic anastomosis, biliary leakage was found on day 12 postoperatively and reoperation was performed. The T-tube was removed from the anastomosis after reoperation, and abdominal infection was controlled, but high fever recurred on day 49 postoperatively. The patient died on day 52 postoperatively. Autopsy revealed biliary leakage and biliary tract necrosis. In another patient, biliary leakage was found on day 3 after operation, and was treated by adequate drainage. Four months after operation, biliary sludge in the common tract was found and treated successfully with oral chemolysis. But biliary sludge or stone recur on one and half year after OLT. Spincterotomy and basket extraction were performed via endoscopic retrograde cholangiopancreatography, and the biliary sludge or stone was cleared out. In case 4, biliary drainage tube cholangiogram showed anastomotic stenosis one month after operation. Three months later, biliary sludge or stone was found beyond anastomotic stenosis. After oral chemolysis (ursodeoxycholic acid) and irrigation with heparinized saline solution via the biliary drainage tube, the biliary sludge disappeared. CONCLUSIONS: To reduce the incidence of biliary complications, adequate infusion of the hepatic artery, complete slushing of the biliary tract, and reduction of injury to the blood supply of the donor biliary tract are essential. Most biliary complications can be treated successfully by non-operative treatment or minimally invasive operation.
