ObjectiveTo investigate the radiological appearances of postoperative complications after living donor liver transplantation for patients with hepatocellular carcinoma under multi-detector row spiral computed tomography (MDCT) and magnetic resonance imaging (MRI) examination. MethodsThirty-nine imaging data in 20 patients with hepatocellular carcinoma after living donor liver transplantation from January 2008 to June 2010 in the West China Hospital were included and analyzed by two radiologists respectively. The relations between the types of complications and radiological appearances were especially recorded. ResultsAll the cases experienced complications to different extent. Common surgical complications occured in 20 cases, including pertitoneal fluid collection (14 cases), pneumoperitoneum (2 cases), swelling of peritoneum, omentum, and mesentery (1 case), abdominal wall swelling (2 cases), pleural effusion (9 cases), and pericardial fluid collection (2 cases). Hepatic vascular complications involved hepatic artery in 3 cases, portal vein in 5 cases. Biliary complications presented in 7 cases, including anastomotic stenosis of biliary duct (6 cases) and bile leak (1 case). Graft parenchymal complications included intrahepatic lymph retention (11 cases), infarction (3 cases), and infection (2 cases). Intrahepatic recurrence in 5 cases, intraperitoneal metastasis in 3 csses and pulmonary metastasis in 2 cases. ConclusionMDCT and MRI have important diagnostic values for postoperative complications after living donor liver transplantation for patients with hepatocellular carcinoma.
Objective To investigate the CT manifestation and clinical significance of the gastrointestinal tract involvement in acute pancreatitis (AP). Methods Two hundreds CT scans in 131 patients with acute pancreatitis between Jan. 1, 2009 and Jun. 30, 2009 were included into the study. Two radiologists analyzed the images retrospectively, paying attention to the CT features of the gastrointestinal tract involvement, such as the style, distribution, and so on. The correlation between gastrointestinal tract involvement and CT severity index, clinical severity grading, and turnover of acute pancreatitis were studied using a SPSS 14.0 for windows statistics software. Results The CT images in 109 (83.2%) patients showed gastrointestinal tract involvement, which distributing mainly stomach, duodenum, jejunum, and transverse colon, and showing mainly the gastrointestinal tract wall thickening and distension. The gastrointestinal tract involvement had positive correlation with CT severity index, clinical severity grading, and turnover of acute pancreatitis (r=0.689， P=0.000; r=0.584， P=0.000; r=0.346， P=0.000). Conclusions The gastrointestinal tract involvement is common complication in acute pancreatitis and concerns with severity and prognosis of the disease. As other extrapancreatic organs involvement, the gastrointestinal tract involvement has important value for severity assessment, prognosis evaluation, and therapeutic effect monitoring of acute pancreatitis.
