DIAGNOSTIC VALUE OF MINIPROBE ULTRASONOGRAPHY IN ESOPHAGEAL PROTRUDING LESIONS

摘要

Objective To investigate the diagnostic value of miniprobe ultrasonography (MPS) in thernprotruding lesions of esophagus. Methods Sixty-two patients with protruding lesions of esophagus were examined with MPS. Results The MPS examination showed diseases of esophageal polyp, inflammatory protruding, esophageal leiomyoma, esophageal leiomyosarcoma, esophageal venous aneurysm, esophageal lipoma, esophageal cyst, esophageal carcinoma, and extra esophageal compression including aorta compression, lung tumor compression and spina compression. Fourteen patients were verified by surgical operations and pathological examinations, resulting in 92. 86% (13/14) diagnosis accuracy rate. Forty-eight cases had results of gastroscope examination consistent with that of MPS. Twelve cases had results of CT and MRI examination consistent with that of MPS. Follow-up was completed on 22 patients. Conclusion Besides imaging the esophageal layer, MPS can precisely locate the histological layer of the esophageal protruding lesions and predict their characters. This indicates its value in the diagnosis and differential diagnosis of the protruding lesions of esophagus. Furthermore, the miniature probe used in MPS examination can pass the structured esophagus, enabling wider application of the examination.
