1. Stenosis affects 4% to 13% of transplant patients. Anastomotic stenosis at the site of bile duct reconstruction accounts for 80% of the cases associated with technical or ischemic problems in early or late stages up to 2 months after transplantation. Nonanastomotic cases account for the other 20%. They occur at a distance of 0.5 cm or more from site of anastomosis and have been associated with ischemic or immune events and with lower survival rates after liver transplantation. 2. Biliary fistulas affect from 2% to 25% of transplant patients and are usually associated with bilomas. Their indications appear earlier than those of stenosis.
