Familial adenomatous polyposis is characterized by the multiple and adenomatous polyps in the colorectum combined with polyps in the stomach and duodenum, while it is rarely seen in the common bile duct (CBD).In July 2013, 1patient with FAP combined with adenomas in the CBD was admitted to the Fujian Provincial Hospital.The patient underwent laparoscopic CBD exploration and resection of masses due to acute pancreatitis 11 months ago, and was confirmed as with adenoma in the distal CBD by postoperative pathological examination.Multiple polyps were found in the stomach, duodenum,CBD, colorectum after admission to hospital, biopsy confirmed that polyps were tubular adenoma.The patient received pancreaticduodenectomy and was diagnosed as with duodenum-CBD tubular adenoma in postoperative pathological examination.The patient was followed up by telephone interview and outpatient examination and had a full recovery, in addition to the increasing of stools frequency and occasioned hematochezia, and then was treated by total colectomy at postoperative month 7.The tubular adenoma was confirmed by postoperative pathological examination.

Objective To investigate the expression of hypoxia inducible factor-1α(HIF-1α) and vascular endothelial growth factor C(VEGF-C) in colon carcinoma,and their relation with clinical pathological parameters and prognosis. Methods Immunohistochemistry was used to detect the expression of HIF-1α and VEGF-C in 65 tissues of colon carcinoma. Results In all cases,the expression of HIF-1α had a positive correlation with the expression of VEGF-C(r= 0.638,P<0.01).The expressions of HIF-1α and VEGF-C had significant correlation with clinical stage and nodal metastasis(P<0.05) ,but had no relationship with sex,age and tumor size(P>0.05). Conclusion The expression of HIF-1α and VEGF-C was correlated with nodal metastasis, tumorigenesis and prognosis of colon/carcinoma.
