Abstract:

Subepithelial lesions can be composed of all layers of the gastrointestinal tract and endosonography is a diagnostic method that is necessary for diagnosis in determining the size limit echo structure and lymph nod proximity in these lesions. In our study, we aimed to evaluate the images obtained by EUS in the context of pathological analyzes obtained later and to evaluate the compliance status. Material and Method: In our study, 36 upper gastrointestinal submucosal mass lesions detected by EUS between 2005 and 2011 in Gazi University Fac of Med Gastroenterology Department were examined retrospectively.To some of these lesions included fine needle aspiration biopsies and surgery material pathological data. Results: Twelve (33. 3%) of 36 submucosal mass lesions detected by endosonography were diagnosed histopathologically by fine needle aspiration biopsy (FNA) and 13 (36.1) were diagnosed by surgery. 22 (61.1%) of the cases were stomach, 5 (13.9%) were duodenum and 9 (25%) were of esophagus origin. Stromal or GIST tumors were considered in 36 EUS evaluations and 14 (38.8%) were pathologically confirmed. The stromal tumor was confirmed in 2 cases with FNA. The diagnosis of stromal tumors in 2 cases with FNA was predicted as suspicious. Conclusion: Endosondography is a valuable method in the evaluation of the upper gastrointestinal system submucosal mass and the addition of fine needle aspiration biopsies to this method plays a supporting role in diagnostic quality in terms of high quality. In our country, endosonographic dominant gastric upper gastrointestinal organ location of submucosal mass lesions is consistent with international literature data.
