2、消化道气钡造影诊断正确率57.14%,B超35.9%,CT 70.59%;纤维十二指肠镜为90.48%;(4)病理组织学诊断恶性肿瘤54例,其中十二指肠腺癌51例,包括十二指肠溃疡伴溃疡边缘癌变1例,乳头状腺瘤伴癌和局限性癌变各1例和十二指肠平滑肌肉瘤3例;乳头腺瘤2例;乳头壶腹部溃疡1例和乳头黏膜下腺癌样增生1例;(5)外科手术,胰十二指肠切除术50例,根治性胃十二指肠切除术4例,根治性十二指肠节段性切除术3例,经十二指肠乳头开口处肿瘤局部切除,胰胆管引流术1例;(6)治疗结果:全组均治愈或好转出院,无手术死亡率;随访结果,获随访21例,1年生存率66.67%,3年生存率42.86%,5年生
3、存率33.33%。结论:纤维十二指肠镜检查和活检是诊断十二指肠肿瘤的主要方法;肿瘤部位不同,治疗方法亦异,乳头上方肿瘤以胃十二指肠切除为主,乳头下方肿瘤以十二指肠节段性切除为主,乳头周围肿瘤根据肿瘤生物学特性选择胰十二指肠切除或经十二指肠肿瘤局部切除(TDE)或ESE。 【关键词】 十二指肠肿瘤 胃十二指肠切除术 纤维十二指肠镜Abstract Objective: To improve the diagnosis and therapy of duodenal tumor.
