The aspiration cytology is a long since well proved method in the diagnosis of near to the body surface alterations in the gastrointestinal tract. The endoscopic fine needle aspiration is a less wide-spread method. Fine needle aspiration cytology has been described as 70-94% accurate for diagnostic upper gastrointestinal tract malignant lesions, and more than 90-99% accurate when used in conjunction with traditional endoscopic forceps biopsy. This technique was performed on 97 consecutive patients parallel with conventional endoscopic biopsy. Sensitivity of the method 86.8%, specificity 98.3%, predictive value in positive cases 96.6%, and in negative cases was 91%. Authors would like to prove with illustrative cases how this technique can be used for the diagnosis of gastrointestinal lesions, primarily in submucosal processes.
