Aspiration cytology in the diagnosis of gastrointestinal tumors

: Early experiences with the new endoscopic aspiration cytology method in the diagnosis of gastrointestinal malignancies are discussed. It was performed in five patients in case of gastric and cardiac cancers and in fifteen ones of colon tumours. Results are compared with those of biopsies and brush cytologies. The new method is quick, reliable and suggested to be widely used in the gastrointestinal endoscopy.
