[Prophylaxis and management of biliary complications after orthotopic liver transplantation].

OBJECTIVE

To investigate the risk factors of biliary complications after orthotopic liver transplantation (OLTx) and the relevant prevention and management strategies.

METHODS

The clinical data of 368 patients undergoing allograft orthotopic liver transplantation, 282 males and 86 females, aged 47.5 (8 - 73), were collected and analyzed retrospectively.

RESULTS

Of the 368 OLTx patients, 36 (9.8%) experienced biliary complications, including simple anastomosis biliary leakage (7 cases), biliary leakage due to injury and omission of accessory hepatic duct (1 case), anastomosis stricture (5 cases), intrahepatic bile duct stricture (3 cases), bile duct stricture secondary to bile duct twist (1 case), calculus of intrahepatic duct (2 cases), bile duct stricture secondary to biliary leakage (2 cases), bile duct stricture combined with intrahepatic biloma (2 cases), bile duct stricture combined with biliary sludge (2 cases), biliary cast syndrome (5 cases), hemobilia (1 case), intrahepatic abscess (3 cases) and Oddi's sphincter dysfunction (2 cases). Among the 36 patients with biliary complications, 23 were cured by nonsurgical therapies; and 13 patients needed abdominal surgical interventions, including retransplantation in 7 cases.

CONCLUSION

Biliary complications after OLT are difficult to treat. Most of these complications can be cured conservatively, such as radiological intervention and endoscopic treatment. When the patients are unresponsive to nonsurgical therapies, or when they suffer from hepatic arterial embolism or arterial stricture simultaneously, surgical interventions, even retransplantation should be considered.
