| 1 | Hemobilia as the initial manifestation of cholangiocarcinoma in a hemophilia B patient显示文摘Hemobilia is a rare manifestation of hemophilia and is usually iatrogenic following liver biopsy. There are only few reports of spontaneous hemobilia in hemophilia patients. Cholangiocarcinoma is a well-established cause of hemobilia. We describe a case of a 70-year-old male, with known haemophilia B and a past history of papillotomy, who presented with classical symptoms of hemobilia. The initial diagnostic work-up failed to demonstrate a potential cause of bleeding other than the coagulopathy. Three months later, he was readmitted to our hospital with a second episode of hemobilia. During the second work-up, a cholangiocarcinoma was diagnosed both by imaging studies and by a significant elevation of cancer antigen 19-9. Although hemobilia could be attributed to hemophilia, especially in a patient with previous papillotomy, an underlying malignancy of the biliary tree should be suspected. | Anastassios C Manolakis Andreas N Kapsoritakis Antonis D Tsikouras Fotis D Tsiopoulos Athanassios K Psychos Spyros P Potamianos | 2008 | World Journal of Gastroenterology2008，14，26： | 5 |
| 2 | Melena:A rare complication of duodenal metastases from primary carcinoma of the lung显示文摘Small bowel metastases from primary carcinoma of the lung are very uncommon and occur usually in patients with terminal stage disease. These metastases are usually asymptomatic, but may present as perforation, obstruction, malabsorption, or hemorrhage. Hemorrhage as a first presentation of small bowel metastases is extremely rare and is related to very poor patient survival. We describe a case of a 61- year old patient with primary adenocarcinoma of the lung, presenting with melena as the first manifestation of small bowel metastasis. Both primary tumor and metastatic lesions were diagnosed almost simultaneously. Upper gastrointestinal endoscopy performed with a colonoscope revealed active bleeding from a metastatic tumor involving the duodenum and the proximal jejunum. Histological examination and immunohistochemical staining of the biopsy specimen strongly supported the diagnosis of metastatic lung adenocarcinoma, suggesting that small bowel metastases from primary carcinoma of the lung occur usually in patients with terminal disease and rarely produce symptoms. Gastrointestinal bleeding from metastatic small intestinal lesions should be included in the differential diagnosis of gastrointestinal blood loss in a patient with a known bronchogenic tumor. | Chrysoula Kostakou Lubna Khaldi Andrew Flossos Andreas N Kapsoritakis Spiros P Potamianos | 2007 | World Journal of Gastroenterology2007，13，8： | 2 |

| 10 | α2-Heremans-schmid glycoprotein(fetuin A)downregulation and its utility in inflammatory bowel disease显示文摘AIM To investigate the impact of inflammatory bowel disease (IBD) on α2-Heremans-Schmid Glycoprotein(AHSG/fetuin A) and potential associations with disease and patient characteristics.METHODS AHSG serum levels were determined in treatment-na?ve newly-diagnosed patients, 96 with ulcerative colitis(UC), 84 with Crohn's disease (CD), 62 with diarrheapredominant or mixed irritable bowel syndrome (IBS, D- and M- types) and 180 healthy controls (HC), by an enzyme linked immunosorbent assay (ELISA).All patients were followed for a minimum period of 3 years at the Gastroenterology Department of the University Hospital of Larissa, Greece. C-reactive protein(CRP), anti-glycan antibodies, anti-Saccharomyces cerevisiae mannan antibodies Ig G, anti-mannobioside carbohydrate antibodies Ig G, anti-laminariobioside carbohydrate antibodies Ig G and anti-chitobioside carbohydrate antibodies Ig A were also determined via immunonephelometry and ELISA, respectively.RESULTS The mean ± SE of serum AHSG, following adjustment for confounders, was 0.32 ± 0.02 g/L in IBD, 0.32 ± 0.03 g/L in CD and 0.34 ± 0.03 g/L in UC patients, significantly lower than in IBS patients(0.7 ± 0.018 g/L) and HC (0.71 ± 0.02 g/L) (P < 0.0001, in all cases). AHSG levels were comparable between the CD and UC groups. Based on AHSG levels IBD patients could be distinguished from HC with about 90% sensitivity and specificity. Further adjusted analysis verified the inverse association between AHSG and penetrating, as well as stricturing CD (partial correlation coefficient: -0.45 and -0.33, respectively) (P < 0.05). After adjusting for confounding factors, inverse correlations between AHSG and CRP and the need for anti-TNFα therapy or surgery, were found (partial correlation coefficients:-0.31,-0.33,-0.41, respectively, P < 0.05, in all cases). Finally, IBD individuals who were seropositive, for at least one marker, had AHSG levels falling within the two lower quartiles (OR = 2.86, 95%CI: 1.5-5.44, P < 0.001) while those with at least two serological markers positive exhibited AHSG concentrations within the lowest quartile (OR = 5.03, 95%CI: 2.07-12.21, P < 0.001), after adjusting for age, sex and smoking.CONCLUSION AHSG can be used to distinguish between IBD and IBS patients or HC while at the same time 'predicting' complicated disease behavior, need for therapy escalation and surgery. Moreover, AHSG may offer new insights into the pathogenesis of IBD, since it is involved in key processes. | Anastassios C Manolakis Gregory Christodoulidis Andreas N Kapsoritakis Panagiotis Georgoulias Elisavet K Tiaka Kostas Oikonomou Varvara J Spyros P Potamianos | 2017 | World Journal of Gastroenterology2017，23，3： | 1 |
