简介：AIM:Toevaluatetheclinicalusefulnessofendoscopicultrasonography(EUS)forthediagnosisoftheinvasiondepthofulcerativecolitis-associatedtumors.METHODS:Thestudygroupcomprised13patientswith16ulcerativecolitis(UC)-associatedtumorsforwhichthedepthofinvasionwaspreoperativelyestimatedbyEUS.Thelesionswerethenresectedendoscopicallyorbysurgicalcolectomyandwereexaminedhistopathologically.Themeanageofthesubjectswas48.2±17.1years,andthemeandurationofUCwas15.8±8.3years.Twolesionsweretreatedbyendoscopicresectionandtheother14lesionsbysurgicalcolectomy.ThedepthofinvasionofUCassociatedtumorswasestimatedbyEUSusinganultrasonicprobeandwasevaluatedonthebasisofthedeepestlayerwithnarrowingorruptureofthecolonicwall.RESULTS:ThediagnosisofUC-associatedtumorsbyEUSwascarcinomafor13lesionsanddysplasiafor3lesions.Theinvasiondepthofthecarcinomaswasintramucosalfor8lesions,submucosalfor2,themuscularispropriafor2,andsubserosalfor1.Eleven(69%)ofthe16lesionsaroseintherectum.Themacroscopicappearancewasthelaterallyspreadingtumor-non-granulartypefor4lesions,sessiletypefor4,laterallyspreadingtumor-granulartypefor3,semipedunculatedtype(Isp)for2,type1for2,andtype3for1.ThedepthofinvasionwascorrectlyestimatedbyEUSfor15lesions(94%)butwasmisdiagnosedasintramucosalfor1carcinomawithhigh-gradesubmucosalinvasion.The2lesionstreatedbyendoscopicresectionwereintramucosalcarcinomaanddysplasia,andbothwerediagnosedasintramucosallesionsbyEUS.CONCLUSION:EUSprovidesagoodestimationoftheinvasiondepthofUC-associatedtumorsandmaythusfacilitatetheselectionoftreatment.
