【Abstract】ObjectiveTo analyze the factors influencing the prognosis of patients with bile duct carcinoma after resection. MethodsThe clinical data of 120 patients with bile duct carcinoma receiving resection in our hospital from 1980 to 2004 were collected retrospectively and clinicopathologic factors that might influence survival were analysed. A multiple factor analysis was performed through Cox proportional hazard model. ResultsThe overall 1year, 3year and 5year survival rates were 71.7%, 32.5% and 19.2% respectively. The single factor analysis showed that the major significant factors influencing survival of these patients were histological type of the lesions, lymph node metastasis, pancreatic infiltration, duodenal infiltration, resected surgical margin, perineural infiltration, peripheral vascular infiltration and depth of tumor infiltration (P＜0.05). Lymph node metastasis, pancreatic infiltration and perineural infiltration were found to be the the statistically significant factors influencing survival by multiple factor analysis through the Cox model. ConclusionThe most important prognostic factors for bile duct carcinoma after resection were lymph node metastasis, pancreatic infiltration and perineural infiltration.
目的 探讨胃肠道穿孔的多层螺旋CT（MSCT）表现及诊断价值。 方法 收集2010年3月－2011年3月18例经手术证实为胃肠道穿孔患者的临床及MSCT资料，回顾性分析了胃肠道穿孔及穿孔部位的MSCT表现。 结果 18例患者中，MSCT明确诊断穿孔17例，对穿孔部位准确定位11例。其中术后诊断胃穿孔4例、十二指肠球部穿孔9例、小肠穿孔3例、结肠穿孔1例、阑尾穿孔1例。MSCT表现有腹腔游离气体，肠壁周围局限性积气、腹腔积液及肠袢积液、肠壁增厚、肠腔周围脂肪间隙密度增高（条纹征）。 结论 MS CT有利于显示腹腔游离气体、胃肠道穿孔部位及其肠壁周围的变化情况，对胃肠道穿孔术前的定性及定位诊断有较明显的优势 ，可为临床提供更多有价值的诊断信息。
