【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 探討胃腸道穿孔的多層螺旋CT（MSCT）表現及診斷價值。 方法 收集2010年3月－2011年3月18例經手術證實為胃腸道穿孔患者的臨床及MSCT資料，回顧性分析了胃腸道穿孔及穿孔部位的MSCT表現。 結果 18例患者中，MSCT明確診斷穿孔17例，對穿孔部位準確定位11例。其中術后診斷胃穿孔4例、十二指腸球部穿孔9例、小腸穿孔3例、結腸穿孔1例、闌尾穿孔1例。MSCT表現有腹腔游離氣體，腸壁周圍局限性積氣、腹腔積液及腸袢積液、腸壁增厚、腸腔周圍脂肪間隙密度增高（條紋征）。 結論 MS CT有利于顯示腹腔游離氣體、胃腸道穿孔部位及其腸壁周圍的變化情況，對胃腸道穿孔術前的定性及定位診斷有較明顯的優勢 ，可為臨床提供更多有價值的診斷信息。
