1、胆囊癌多层螺旋CT分期及手术可切除性评价【摘要】目的评价16层螺旋CT三期增强后三维重建在确定胆囊癌的CT分期和评价手术可切除性的价值。方法27例临床和超声检查怀疑胆囊癌的病例,前�性分析其16层螺旋CT三期增强表现,其中20例做了胆囊癌根治性切除术或姑息手术的患者。三维容积重建评价血管的解剖及受侵犯情况,CT分期及可切除性评价与手术结果对照。结果根据CT表现,8例肿瘤可切除,12例不能切除。术中发现11例肿瘤可切除,9例不能切除,3例CT分期过高,认为不能切除的病例是由于CT误诊十二指肠受浸润。在评价胆囊癌可切除性方面,CT的敏感性为72.7%(8/11),
2、特异性为100%,准确性为85%(17/20),在肝脏和血管受侵犯方面和CT评价和手术所见完全一致,接受根治性胆囊癌切除的患者中发现6例血管变异。结论三期增强螺旋CT三维重建是一种可靠的分期胆囊癌的影像方法,术前可确定血管的走行路径。�【关键词】癌;胆囊;16层螺旋CT��16-slicespiralCTinstagingandassessingrespectabilityofgallbladdercarcinomaMENGYong,KONGFan-bin,WUXiao-jin.Departmentof13CT,theFirstPeople’sHospital
