摘要 大肠侧向发育型肿瘤(LST)是指起源于大肠粘膜的一类隆起型病变,这类病变极少向肠壁深层垂直侵犯,而主要沿粘膜表面呈侧向浅表扩散,故被称为侧向发育型肿瘤,大肠LST的病变形态和发生发展有一定的特殊性,不同于一般的腺瘤,并与大肠癌的关系密切,目前大肠LST在国内尚未见报道,本文对2000年12月-2001年10月作者所在医院常规肠镜检查中发现的25例大肠LST患者的诊断及治疗进行了总结分析。该25例病例共发现26处病变,内镜下大体分型为颗粒均一型11处,结节混合型15处,病理检查发现粘膜内癌3例,锯齿状肿瘤2例;病变大小11-20删除th ,21-30mm9处,31mm以上11处,其中最大者60mm×12mm,26处病变的腺管开口类型以Ⅳ型为主,占61.54%916/26);ⅤA型2处,与另1处Ⅳ型共3处病理诊断为粘膜内癌,ⅢL型8处,病理诊断为管状绒毛状腺瘤,25例病例全部在发现病变的同时或择期进行粘膜剥离或分片粘膜剥离治疗,全部病例未发生任何出血或穿孔等并发症。 Laterallyspreadingtumor(LST)originatesfromthelargeintestinemucosawithprominentleisionsthatmainly extendlaterallyotherthanvertically.Thepathologicalmorphologyandevolvementof thisdiseasedistinguishitselffromother adenomas,anditscloseassociationwithcolorectalcancerhasbeennoted.Up tillnow,no reporton LST involvingthelarge intestinehasbeenavailableinChina,thereforewe presentlyreportourexperienceinthediagnosesandtreatmentof25LST patients(26lesions)identifiedwithconventionalendoscopyandmucosastainingduringtheperiodfromNov,2000to Oct,2001.Amongthe26lesions,11wereclassifiedintogranularhomogeneoustype,15intonodularmixedtype,and3patients werefoundto haveintramucosacarcinomaand2serratedadenoma.Thebiggestlesionwas60mm×70mm,thesmallest being11mm×12mm,and6lesionswerewithintherangeof11to20mm,9within21to30mm withtherest11lesions exceeding31mm in diameter.TypeⅣpitpatternwas predominantin thethe26lesions,accountingfor a proportionof61.54%(16/26).Two lesionswithⅤ A pitpatternand1withⅣpatternwerepathologicallydiagnosedto be intramucosa carcinoma,and8withtypeⅢ L pitpatternweretubulovillousadenoma.Immediateor electiveendoscopicmucosaresectionor partitionedmucosaresectionwasperformedinthe25caseswithoutincidencesof thecomplicationsas bleedingor perforation.
