The clinlical application of endoscopy for hepatobiliary necrosis after liver transplantation / 中华消化内镜杂志

ABSTRACT

Objective To explore the technological and therapeutic value of endoscope for removal of hepatobiliary necrosis after liver transplantation.Methods Data of 36 patients with suspected hepatobiliary diseases,who underwent choledochoscopy or duodenoscopy to remove necrosis after liver transplantation,were reviewed.Liver function before and after the treatment were compared.Results Hepatobiliary necrosis located in common bile duct (n =6),intrahepatic bile duct (hilar bile duct included) (n =24) and intraand extra-hepatic duct (n =6).The total success rate was 72.2％ (26/36).Full clearance of bile duct necrosis was accomplished in 16 patients,partial clearance in 15 patients and the necrosis could not be removed in 5 others.The serum bilirubin and transaminase decreased significantly,compared with those before endoscopic treatment (P ＜ 0.05).No serious complications or death related to endoscopy occurred during the treatment.After 6-84 month follow-up,in 17 survivals,3 patients underwent a second liver transplantation with good prognosis.All the survivals had a life of good quality with no placed drainage tube except for one with drainage tube for four years with unstable serum bilirubin.Nineteen patients died from biliary tract related complications or other diseases during the long-term follow-up,among which eleven patients survived beyond four years.Conclusion Endoscopy for hepatobiliary necrosis removal,a minimally invasive method,is effective and safe.
