title: Endoscopic ultrasonography as an adjunct to fine needle aspiration cytology of the upper and lower gastrointestinal tract.
abstract: Twenty consecutive patients with either extrinsic or submucosal masses or gastric ulcers suspicious for malignancy with previously negative conventional forceps biopsies and/or brush cytology underwent a combined approach of endoscopic ultrasound (EUS) followed by fine needle aspiration cytology. Diagnostic results were obtained in 17 of 20 patients. The three patients with indeterminate aspirates had EUS findings strongly supportive of the final diagnosis. EUS combined with fine needle aspiration cytology appears to be of value in the evaluation of extrinsic, submucosal, and ulcerative lesions of the gastrointestinal tract.
