Endoscopically directed fine needle aspiration biopsy of gastric and esophageal lesions.
Endoscopically directed fine needle aspiration (FNA) has been reported to be a valuable adjunct to forceps biopsy in the evaluation of gastric and esophageal lesions. In our series of 38 cases with endoscopically detected mucosal and submucosal abnormalities, FNAs were obtained with a Stifcor transbronchial aspiration needle. Four cases were reported as insufficient. Five aspirates correctly documented the presence of a neoplasm, but three failed to identify a subsequently histologically confirmed adenocarcinoma. Two cases were falsely suspicious for adenocarcinoma. FNA correctly excluded lymphoma in 12 patients with thick gastric folds clinically suspicious for lymphoma. FNA is a useful adjunct to forceps biopsy of neoplastic and inflammatory lesions in both mucosal and submucosal locations within the upper gastrointestinal tract.
