十二指肠空肠曲是中、上两段小肠位于左上腹深处的连接部和急转直下的通道,该部肿瘤极为少见。该部肿瘤的超声诊断,国内尚未见报告。本文试图通过经手术和病理证实该部肿瘤8例的误诊分析及多年腹部超声的实践体会说明,超声对该部中、晚期肿瘤的诊断虽然至今有相当的难度,但也是有可能的。 The duodenal jejunal curvature is the junction between the middle and upper segments of the small intestine located deep in the left upper abdomen, and the passage that runs down and down. The tumor in this area is extremely rare. Ultrasound diagnosis of this department’s tumor has not yet been reported in China. This article attempts to confirm the misdiagnosis analysis of 8 cases of the tumor and the practical experience of years of abdominal ultrasound through surgery and pathology. Although the diagnosis of the middle and late stage tumors by ultrasound is still quite difficult, it is also possible.
