Abstract

Background/aims: The aim of this study was to evaluate the accuracy of endoscopic ultrasonography (EUS) and consistency of the EUS findings with histopathologic examination. Methods: EUS was performed in 90 patients with upper gastrointestinal tract submucosal tumors, followed in Turkiye Yuksek Ihtisas Hospital, Gastroenterology Clinic. Histopathological diagnosis and EUS findings of 25 of 90 patients were compared. Results: 48.9% of the lesions were found to have arisen from muscularis propria, 33.3% from submucosa, 6.6% from mucosa and 10% from muscularis mucosae, and 1.2% from serosa of the 90 patients. In 25 patients histopathologic confirmation was done. 24% of 25 patients were leiomyoma, 20% polyp, 12% lipoma and the remainder were teratoma, carcinoid tumor, adenocarcinoma, polyp and leiomyosarcoma. EUS was successful in detecting all tumors. EUS diagnosis was consistent with histopathogical diagnosis in all patients with EUS findings as leiomyosarcoma (n=2) and polyp (n=6), in 46.2% of patients with EUS findings as leiomyoma, and in 50% of those with lipoma. Conclusions: EUS is an accurate means of evaluating and diagnosing submuocal lesions of the gastrointestinal tract.
