Abstract:
ObjectiveTo explore the feasibility of hilar bile duct using ultrasonography (US) in identification of different types of biliary strictures after orthotopic liver transplantation.MethodsThe US images of hilar bile duct of 62 patients with non-anastomotic biliary stricture (NAS) and 30 patients with anastomotic biliary stricture (AS) were reviewed.Four US feathers including the presence of hilar biliary dilatation,the display of hilar biliary lumen,the thickening of bile duct wall and the echo of bile duct wail were assessed.Results The presence of hilar biliary dilatation,the display of hilar biliary lumen,the thickening of bile duct wall showed a significant difference between NAS and AS groups (P＜0.001).The feature with the greatest performance in the diagnosis of NAS was unclear displayed hilar biliary lumen.The sensitivity,specificity and accuracy were 93.7％,86.7％ and 92.3％,respectively.Conclusions The observation of hilar bile duct has great vaule in identification of different types of biliary strictures after orthotopic liver transplantation.The display of hilar biliary lumen is more likely to differentiate between NAS and AS
