Fine needle aspiration cytology of the pancreas. An analysis of its use in 52 patients.

An experience with fine needle aspiration cytology of the pancreas over a five-year period in 52 patients is described. It was a highly specific test (93%), with a 100% predictive value for a positive test, regardless of the method used to obtain the cytologic sample. On the other hand, the sensitivity was relatively low, especially for percutaneous biopsies (58%). These results are similar to those reported by others. The complication rate was low (less than 1%). FNA cytology is now the procedure of choice in establishing a definitive diagnosis of pancreatic carcinoma in our institution.
