Evaluation of leiomyoma of the esophagus with endoscopic ultrasonography

Fourteen patients with suspected leiomyoma of the esophagus were studied by endoscopic ultrasonography, computed tomography, endoscopy and barium swallow. The results were correlated with the histology of the resected specimens: in 2 patients with a peduncolated leiomyoma originating from the second echographic layer, endoscopic resection was performed. Endoscopic ultrasonography was superior to other imaging techniques in detection and staging of leiomyoma because it can determine the layer of origin, the direction of the growth and the consistency of the tumor.
