Analysis of endosonographed pancreatic lesions w？th surgical and needle aspiration biopsy data by pathological results: 6 year experience

ABSTRACT Purpose: Endoscopic ultrasonography (EUS) is a widely accepted diagnostic method for the evaluation of pancreatic lesions. Fine-needle aspiration biopsies performed with EUS play an important role in the grading and the histological diagnosis of pancreatic lesions. We aimed to evaluate the imaging findings with endosonography (EUS) and try investigate the correspondence with the patients pathological results. Material and Methods: In our study, EUS imaging of 101 patients with pancreatic mass in abdominal computed tomography was compiled. At the same time, fine needle aspiration biopsies were applied simultaneously to some of these cases. Pathologic diagnoses obtained by aspiration needle biopsy and pancreas surgery were supplemented in our study. Results: The most common localization in pancreatic mass imaging with EUS is in the pancreatic head (46 cases, 45.5%). The most frequent diagnosis were pancreatic carcinoma (49 cases, 48.5%) . 32 patients (31.7%) underwent surgery for pancreatic mass. Thirty needle aspiration biopsies were performed in 30 (29.7%) cases after applying EUS. Pancreatic cancer was diagnosed in 12 (40%) of the patients who had endosonographically fine needle aspiration biopsy and 19 (59.4%) of the surgical cases. There was no difference in pancreatic localization between the patients with the preliminary diagnosis of pancreatic cancer and other preliminary pancreatic mass diagnoses. In our study, there was no difference between the genders according to localization, size and diagnostic biopsy methods. Conclusion: EUS is an important method in diagnosing pancreatic mass lesion, especially in pancreatic carcinomas and in surgical decision. The support of fine needle aspiration biopsies and surgical methods after these images is of vital importance in the diagnosis
