多层螺旋CT扫描在食管癌术前分期评估中的应用价值[摘要]目的分析多层螺旋CT扫描在食管癌术前分期评估中的应用价值。方法回顾性分析我院2011年1月〜2014年1月收治的食管癌患者38例的临床资料,分析38例食管癌患者MSCT检查显示管壁的厚度、肿瘤的外侵程度、有无淋巴结及远处脏器的转移,并对38例食管癌术前CT分期与术后病理对照进行分析。结果38例食管癌患者中鳞癌32例,CT表现为食管管壁环形增厚6例,食管腔内肿块4例,管壁偏心不规则增厚22例(食管局部厚度为5〜55mm,其中管壁增厚0.5〜1.0cm3例,1.1〜2.0cm16例,2.1〜3.0cm2例,>3.0cm1例),2例为早期食管癌,CT未见阳性表现,4例未见明显增强征象。21例管腔出现狭窄,狭窄的食管壁边缘僵硬而不规则,呈环状狭窄,4例管腔闭塞。18例食管周围脂肪间隙消失。4例气管受压变形,3例左主支气管变窄、移位,1例食管支气管瘘。38例食管癌患者术前行CT检查,根据Moss分期分为I期3例、II期6例、III期25例、IV期4例。其中癌侵犯主动脉1例,侵犯气管2例,并发肝转移2例,肺转移1例。10例出现淋巴结转移,大部分增大淋巴结均有强化少部分淋巴结中心坏死,边缘强化。淋巴结大小为15〜30mm。结论多层螺旋CT扫描在食管癌术前分期评估中具有重要价值,有助于选择合适的手术方案。[关键词]螺旋CT;食管癌;术前分期[]R735.1[文献标识码]B[]1673-9701(2015)11-0132-03[Abstract]ObjectiveToanalyzetheapplicationvalueofmultislicespiralCTinpreoperativestagingevaluationofesophagealcarcinoma.MethodsRetrospectiveanalyzedtheclinicaldatainourhospitalfromJanuary2011toJanuary2014of38casesofesophagealcancerpatients,analyzed38casesofesophagealcancerpatientsunderwentMSCTexaminationandshowedthatthepipewallthickness,tumorinvasiondegree,lymphnodeanddistantorganmetastasis.In38casesofesophagealcarcinomaandCTstagingofpreoperativeandpostoperativepathologywereanalyzed.Results32casesofsquamouscellcarcinomaof38esophaguscancerpatients,CTshowed6casesofesophagealwallthickening,4casesofesophagealintraluminalmasses,irregulareccentrictubewallthickeningin22cases(esophagealpartialthicknesswas5~55mm,thetubewallthickeningin0.5~1.0cmthreecases,1.1-2.0cmin16cases,2.1-3.0cmin2cases,>3.0cmonecase),2casesofearlyesophagealcancer,noCTpositiveexpression,4patientshadnoobviousenhancementfeatures.In21casesthelumenappearedstenosis,esophagealwalledgestiffnarrowandirregular,annularstenosis,4casesofocclusionofthelumen.In18casesofesophagealsurroundingfatspacedisappeared.4casesoftrachealcompressiondeformation,leftmainbronchialnarrowing,transpositionin3cases,including1caseofesophagealandbronchialfistula.In38patientswithcarcinomaofesophagusCTexaminationbeforeoperation,accordingtotheMossstagingforstageI3cases,stageII6cases,stageIII25cases,stageIV4cases.Thecancerinvadingaortain1case,2caseswithtrachealinvasion,2casescomplicatedwithhepaticmetastasis,lungmetastasisin1case.10casesoflymphnodemetastasis,mostofenlargedlymphnodeswerestrengthened,fewlymphnodenecrosisinthecenter,edgeenhancement.Lymphnodesizeof15-30mm.ConclusionMultislicespiralCTscanninginstagingevaluationhasanimportantvalueinesophagealcarcinomabeforeoperation,helpstoselectthesuitableoperationscheme.[Keywords]SpiralCT;Esophagealcancer;Preoperativestaging食管癌(esophagealcarcinoma)是常见的消化道恶性肿瘤之一,发病率和病死率较高[1]。手术切除是治疗食管癌的主要手段之一,但切除率主要取决于病变部位及临床病理分期,因此对食管癌进行准确的术前分期至关重要[2]。随着影像学检查技术的不断发展,食管癌的影像学检查手段也取得了较大的发展。X线钡餐造影和CT检查为常见且常应用的检查方法,CT扫描检查弥补了传统食管X线钡餐造影检查只能观察食管...
