目的与方法:本文采用七种不同的诊断方法,对经手术病理证实的62例并出血的消化道平滑肌瘤诊断率进行了研究.结果:本病误诊率达41.9%,其最常见的好发部位为:(1)食管下段88.9%,(2)胃底81.8%;(3)小肠,主要是空肠62.09%.以结肠最为常少见.另外,七种诊断手段中,以动脉血管造影诊断阳性率最高(77.8%),其次为内窥镜(71.4%)、ECT(60.0%)及肠系钡餐检查(50.0%),B-型超声诊断率最低(15.8%).结论:(1)平滑肌瘤系引起消化道出血的原因之一,应重视本病;(2)临床表现与病理类型不同的关;(3)合理选择、综合应用特检的手段系提高本病诊断率的关键.
Objectives and Methods: Seven different diagnostic methods were used in this study to diagnose the rate of diagnosis of 62 patients with gastrointestinal leiomyosarcoma diagnosed by surgery and pathology. Results: The rate of misdiagnosis of this disease reached 41.9%, and its most common good. The sites were: (1) 88.9% of the lower esophagus, (2) 81.8% of the fundus, (3) small intestine, mainly jejunum, 62.09%, and most often rare in the colon. In addition, seven diagnostic methods were used to diagnose arterial angiography. The positive rate was highest (77.8%), followed by endoscopy (71.4%), ECT (60.0%), and barium meal examination (50.0%). The B-mode ultrasound diagnosis rate was the lowest (15.8%). Conclusion: (1) One of the reasons that leiomyoma is a cause of digestive tract hemorrhage should pay attention to this disease; (2) The clinical manifestation is different from the pathological type; (3) The key to improve the diagnosis rate of this disease is to use reasonable selection and comprehensive application of special inspection. .
