| 4 | Fatal gastrointestinal histoplasmosis 15 years after orthotopic liver transplantation显示文摘We report a case of ileo-colonic Histoplasmosis without apparent respiratory involvement in a patient who had previously undergone an orthotopic liver transplant(OLT) for primary biliary cholangitis 15 years earlier. The recipient lived in the United Kingdom,a non-endemic region for Histoplasmosis. However,she had previously lived in rural southern Africa prior to her OLT. The patient presented with iron deficiency anaemia,diarrhoea,abdominal pain and progressive weight loss. She reported no previous foreign travel,however,it later became known that following her OLT she had been on holiday to rural southern Africa. On investigation,a mild granulomatous colitis primarily affecting the right colon was identified,that initially improved with mesalazine. Her symptoms worsened after 18 mo with progressive ulceration of her distal small bowel and right colon. Mycobacterial,Yersinia,cytomegalovirus and human immunodeficiency virus infections were excluded and the patient was treated with prednisolone for a working diagnosis of Crohn's disease. Despite some early symptom improvement following steroids,there was subsequent deterioration with the patient developing gram-negative sepsis and multi-organ failure,leading to her death. Post-mortem examination revealed that her ileo-colonic inflammation was caused by Histoplasmosis. | Nikita Agrawal David EJ Jones Jessica K Dyson Tim Hoare Sharon A Melmore Stephanie Needham Nick P Thompson | 2017 | World Journal of Gastroenterology2017，23，43： | 1 |
| 5 | Successful en bloc resection of primary hepatocellular carcinoma directly invading the stomach and pancreas显示文摘Multivisceral surgical resection for cure was successfully performed in a 70-year-old man suffering from a primary hepatocellular carcinoma(HCC)associated with direct invasion to the stomach and pancreas.The patient presented with gastric outlet obstruction,upper abdominal pain and a history of chronic liver disease due to hepatitis B virus(HBV)infection.Upper gastro-intestinal(GI)endoscopy revealed an infiltrating tumor protruding through the gastric wall and obliterating the lumen.Computer tomograghy(CT)and magnetic resonance imaging(MRI)scan demonstrated a 15-cm tumor in the left lateral segment of the liver with invasion to the stomach and pancreas.Alpha-foetoprotein (AFP)levels and liver function tests were normal.The patient underwent an en bloc left hepatectomy,total gastrectomy,distal pancreatectomy with splenectomy and radical lymphadenectomy.Pathology revealed a poorly differentiated,giant cell HCC involving the stom-ach and pancreas.Disease-free margins of resection were achieved.The patient's postoperative course was uneventful.Sixteen months after surgery,he has norecurrence or distal metastasis.Direct invasion of HCC into the GI tract is rarely encountered.Complete surgical resection should be considered in selected patients with an appropriate hepatic functional reserve. | Dimitris P Korkolis Chrysanthi Aggeli George D Plataniotis Emmanuel Gontikakis Helen Zerbinis Nikitas Papantoniou Dimitris Xinopoulos Nikiforos Apostolikas Perikles P Vassilopoulos | 2009 | World Journal of Gastroenterology2009，15，9： | 1 |
