Abstract:
Objective To provide information and assistance for research of bile duct injury in OLT through endoscopic observation and treatment of biliary complications after liver transplantation.Methods After OLT, all the cases in normal group, bile duct injury group and hepatic artery injury group were observed, diagnosed and recorded respectively. Meanwhile, the biopsy was performed through the endoscopy for pathological examination. For those cases without T tube, the biopsy was conducted by choledochoscopy in combination with duodenoscopy. Results The exterior and interior bile duct anatomy of the 9 cases in the normal group was normal. They had no bile duct stenosis and scar, their bile duct mucous membrane looked good and the anastomosis of the donor-receptor bile duct healed well. Restored mucous tissue coating with intact epithelium was found by pathological examination. Fibrous tissue and small vascular proliferation happened under epithelium scattered with plasmocyte and lymphocyte. Various kinds of bile duct stones-simple, multiple and casting mould type, were found in 12 cases with bile duct injury. Bile duet mucous membrane injured in different degrees was repaired after stone removed and obstruction relieved by endoscope. Bile duct tree becoming normal was seen by pacification examination. Three cases in the hepatic injury group had bile duct ischemic necrosis, losing of normal structure without bile duct wall and mucous membrane. Conclusion Bile ducts are injured in different degrees in OLT. The choledochofibroscopy is of the first choice for diagnosis and treatment of complications after OLT.
