Aim The aim of the present study was to evaluate the risk factors and outcomes of gastrointestinal perforation post-liver transplantation. Patients and Methods Eleven patients were found to have complications as a result of gastrointestinal perforation post-liver transplantation at our centre from May 2008 to February 2014. Seven of these patients were selected for statistical analysis. Each patient was randomly matched with six recipients in age (± 10 years), primary disease and sex. Factors, including cold ischaemic time, blood loss volume, previous hepatobiliary surgery history and 1-year survival rate, were compared between the two groups. Results The sites of perforation were the stomach ( n = 2), duodenum ( n = 2), jejunum ( n = 1), ileum ( n = 3) and colon ( n = 3). Univariate analysis showed a significant difference in previous hepatobiliary surgery history ( P < 0.01). No difference was found in portal venous cross-clamp time, cold ischaemic time, model for end-stage liver disease score, body mass index, steroid therapy or blood type incompatibility. Previous hepatobiliary surgery history was found to be an independent risk factor in the multivariate analysis ( P < 0.05). The 1-year survival rate was lower in the perforation group ( P < 0.01). Conclusion Gastrointestinal perforation leads to a high rate of morbidity and mortality, and significantly decreases graft and recipient survival. A history of hepatobiliary surgery is a risk factor of this complication. Careful dissection and avoiding iatrogenic injury during operation are important. [ABSTRACT FROM AUTHOR]

Hepatic vein reconstruction is one of the crucial issues in living donor liver transplantation ( LDLT). In the present study, we report on a right liver LDLT excluding middle hepatic vein ( MHV) using an MHV-dominant graft. Two large-sized inferior right hepatic veins were anastomosed to the recipient's inferior vena cava, respectively, in an end-to-side fashion. MHV tributaries were reconstructed using Y-shaped cryopreserved iliac artery, but resulted in segment VIII congestion. A Fogarty catheter was then used to take out the thrombus and control the bleeding when anastomosis was being performed. The patient recovered uneventfully. Postoperative computed tomography showed patent interposition grafts and normal perfusion of the liver. The patient was doing well 13 months after transplantation. [ABSTRACT FROM AUTHOR]

Aim To develop a clinical strategy for the interposition of portomesenteric vein (PMV) by means of allograft in pancreatic surgery. Patients and Methods Between January 2004 and September 2011, nine patients had PMV interposition using allograft for massive vascular involvement by pancreatic tumour during pancreaticoduodenectomy. Their clinical outcomes were reviewed. Results After anastomosis of the allografts, three of which were fresh portal venous allografts, and six of which were cryopreserved iliac arterial allografts harvested from cadaveric donors, follow-up Doppler ultrasonography revealed neither thrombosis nor stenosis. Conclusions The allografts might provide a feasible and clinically-attractive option in PMV interposition in the radical resection of pancreatic tumours. [ABSTRACT FROM AUTHOR]

Peliosis hepatis ( PH) is a rare benign liver lesion, characterized by the presence of multiple blood-filled cavities and marked dilation of the hepatic sinusoids throughout the hepatic parenchyma. It is often confirmed after the liver resection or liver biopsy. In the present study, we report a case of a 41-year-old woman who presented with a asymptomatic right hepatic mass. The imaging findings of the mass, including computed tomography and magnetic resonance imaging, showed centrifugal progression of enhancement during the portal and delayed phases. Because of the possibility of hepatic malignancy, partial resection of the liver was performed. The final pathological diagnosis was PH. By referring to the relevant literature, we conclude that, as a result of insignificant clinical manifestation and imaging features, PH should be kept in mind for patients with hepatic mass.
