【摘要】 目的:分析上消化道同时性多原发癌的X线表现,探讨其X线诊断价值及漏诊误诊原因。方法:对经病理证实的同时性上消化道多原发癌的X线资料进行回顾性分析。结果:24例上消化道多原发癌中,食管-食管型10例,食管-胃型9例,胃-胃型5例,除2例食管为3处癌灶外,其余均为双癌灶。食管共发现31个癌灶,上段6个,中段13个,中下段4个,下段8个,中、下段合计25个,占80.6%。胃部病变中贲门6个,胃底2个,胃体3个,胃窦7个。24例中漏诊、误诊8例。结论:X线检查诊断上消化道多原发癌具有重要价值,但应警惕上消化道多原发癌易于漏诊、误诊。更多还原

【Abstract】 Objective:To analyze the radiological features of multiple primary carcinomas (MPC) in upper gastrointestinal tract (MPCUGT), to evaluate the diagnostic value of X-ray examination, and to study the causes of leaky diagnosis and misdiagnosis.Methods:X-ray findings of the 24 cases proved pathologically were retrospectively analyzed. Results:Of the 24 cases, esophageal MPC was seen in 10 (EMPC), esophageal and gastric MPC (EGMPC) in 9 and gastric MPC (GMPC) in 5. All of those cases were of double lesions, except 2 cases with 3 lesions in the esophagus. The esophageal lesions were located at upper (n=6),middle (n=13) ,middlelower (n=4) or lower (n=8) segment of the esophagus, while, the gastric lesions were located at the gastric cardia (n=6), fundus (n=2), body (n=3) and antrum (n=7). 80.6% of the lesions with MPC of esophagus were mostly distributed in middle and lower section of the esophagus. 8 of the 24 cases were leaky diagnosis and misdiagnosis.Conclusion:X-ray examination is of great value for the diagnosis of MPCUGT. The rate of missed diagnosis of MPCUGT was higher.更多还原
