If untreated, congenital biliary atresia leads to liver cirrhosis, liver failure and premature death. The present study aimed to evaluate the outcomes of orthotopic liver transplantation in children with biliary atresia. METHOD: We retrospectively analyzed 45 patients with biliary atresia who had undergone orthotopic liver transplantation from September 2006 to August 2012. RESULTS: The median age of the patients was 11.0 months (5-102). Of the 45 patients, 41 were younger than 3 years old. Their median weight was 9.0 kg (4.5-29.0), 34 of the 45 patients were less than 10 kg. Thirty-one patients had undergone Kasai portoenterostomy prior to orthotopic liver transplantation. We performed 30 living donor liver transplants and 15 split liver transplants. Six patients died during a follow-up. The median follow-up time of surviving patients was 11.4 months (1.4-73.7). The overall 1-, 2- and 3-year survival rates were 88.9%, 84.4% and 84.4%, respectively. CONCLUSION: With advances in surgical techniques and management, children with biliary atresia after liver transplantation can achieve satisfactory survival in China, although there remains a high risk of complications in the early postoperative period.展开更多

We report a rare case of orthotopic liver transplantation in a patient with a giant MHL. In 2013, a 34-year-old female sought medical advice after a 2-year history of progressive abdominal distention and respiratory distress. Physical examination revealed an extensive mass in the abdomen. Computed tomography(CT) of her abdomen revealed multiple liver cysts, with the diameter of largest cyst being 16 cm × 14 cm. The liver hilar structures were not clearly displayed. The adjacent organs were compressed and displaced. Initial laboratory tests, including biochemical investigations and coagulation profile, were unremarkable. Tumor markers, including levels of AFP, CEA and CA19-9, were within the normal ranges. The patient underwent orthotopic liver transplantation in November 2013, the liver being procured from a 40-year-old man after cardiac death following traumatic brain injury. Warm ischemic time was 7.5 min and cold ischemic time was 3 h. The recipient underwent classical orthotopic liver transplantation. The recipient operative procedure took 8.5 h, the anhepatic phase lasting for 1 h without the use of venovenous bypass. The immunosuppressive regimen includedintraoperative induction with basiliximab and high-dose methylprednisolone, and postoperative maintenance with tacrolimus, mycophenolate mofetil, and prednisone. The recipient's diseased liver weighed 21 kg(dry weight) and measured 41 cm × 32 cm × 31 cm. Histopathological examination confirmed the diagnosis of an MHL. The patient did not experience any acute rejection episode or other complication. All the laboratory tests returned to normal within one month after surgery. Three months after transplantation, the immunosuppressive therapy was reduced to tacrolimus monotherapy, and the T-tube was removed after cholangiography showed no abnormalities. Twelve months after transplantation, the patient remains well and is fulfilling all normal activities. Adult giant MHL is extremely rare. Symptoms, physical signs, laboratory results, and radiographic imaging are nonspecific and inconclusive. Surgical excision of the lesion is imperative to make a definite diagnosis and as a cure. Liver transplantation should be considered as an option in the treatment of a non-resectable MHL.展开更多
