Abstract:
The aim of the present study is to demonstrate the usefulness of intraoperative fine needle aspiration (FNA) of pancreatic lesions in 30 patients. A conclusive diagnosis was done in 27 patients and the diagnoses of three patients were deferred. No complications followed the procedure. Based on histologic findings of the resected specimens in 20 cases and of cell blocks in 10 cases, the final diagnoses were adenocarcinoma in 19 cases, chronic pancreatitis in nine cases and tuberculosis in two cases. The sensitivity, specificity and diagnostic accuracy were 95%, 100% and 96% resepectively and there were no false positives. The smear of aspirate was stained with toluidine blue and examined by light microscope. The presence of there-dimensional clusters of disoriented cells and the increased nuclear/cytoplasmic ratio with large prominent nucleoli were the most helpful criteria for a diagnosis of malignancy in the pancreas. The intraoperative FNA of pancreatic lesions was considered as a simple, safe, and highly specific and sensitive tool in differentiating benign from malignant lesions. The intraoperative FNA can be recommended as the first tool of choice of intraoperative diagnostic procedure in lesions of the pancreas.
