目的探讨超声检查对胃肠道间叶组织源性肿瘤的诊断价值。方法25例经手术病理证实的胃肠道间叶组织源性肿瘤患者,其中男性9例,女性16例;年龄29~80岁,平均年龄57.2岁。回顾性分析其超声表现,并对超声诊断结果与病理诊断结果进行对比分析。结果间质瘤呈圆形或椭圆形,形态规整,边界清楚,内呈均匀低回声,血液运行不丰富;较大者形态不规整,内部回声不均并可见液性区,血液运行丰富。平滑肌瘤呈椭圆形或分叶状,形态规整,边界清楚,呈均匀低回声,肿瘤部位消化道壁结构完整。平滑肌肉瘤瘤体较大,形态不规整,边界不清楚,呈不均匀低回声;有坏死出血时声像图可见液性暗区。神经鞘瘤呈球状,形态规整,边界清楚,由黏膜下层向胃腔外生长,肿物部位黏膜连续完整。经手术病理确诊的25例胃肠道间叶组织源性肿瘤超声检出率为100%,定位诊断准确率为84%,超声定性诊断准确率为68%。结论超声检查对胃肠道间叶组织源性肿瘤的诊断有较大临床应用价值。
Objective To investigate the diagnostic value of ultrasonography in gastrointestinal mesothelial tissue-derived tumors. Methods Twenty-five patients with gastrointestinal mesenchymal tissue tumors confirmed by pathology were included. Among them, there were 9 males and 16 females. The age ranged from 29 to 80 years and the average age was 57.2 years. Retrospective analysis of its ultrasound performance, and the ultrasound diagnosis and pathological diagnosis results were compared. Results The stromal tumors were round or oval in shape, with well-defined borders, uniform hypoecho within, and poor blood flow; larger forms were irregular, internal echoes were uneven and fluid areas were visible, and blood flow was abundant. The leiomyomas are elliptical or lobulated, regular in shape, clear in boundary, and uniformly hypoechoic. The gastrointestinal wall in the tumor site is structurally intact. The tumors of leiomyosarcoma are large in size, irregular in shape, unclear in boundary, and inhomogeneously hypoechoic; when there is hemorrhage and hemorrhage, the dark areas can be seen in the acoustic image. The schwannoma is spherical, regular in shape and clear in border. It grows from the submucosa to the outside of the stomach cavity, and the mucosa of the tumor site is continuous and complete. Twenty-five patients with gastrointestinal mesenchymal origin tumors diagnosed by pathology were found to have an ultrasound detection rate of 100%, a localization diagnosis accuracy rate of 84%, and an ultrasound qualitative diagnosis accuracy rate of 68%. Conclusion Ultrasonography has great clinical application value in the diagnosis of gastrointestinal mesenchymal origin tumors.
