Abstract

Confirmation of the nature of focal pancreatic lesions plays a pivotal role in treatment. There are many different types of sampling procedures such as ultrasound-guided fine needle aspiration (US FNA), endoscopic ultrasound-guided fine needle aspiration (EUS FNA), surgical biopsy, ultrasound guided biopsy and computed tomography. We reviewed 18 consecutive ultrasound-guided fine-needle aspiration cytological sampling procedures for focal pancreatic lesions. Result: median number of aspiration was 1.4 times/patient, painless was seen in 17/18 patients. Sensitivity, specificity, positive prediction value and negative prediction value of US FNA in diagnosis pancreatic cancer were 90.9%, 100%, 100%, 87.5% and 94.4%, respectively. No complications related to US-FNA were noted. Conclusion: US FNA cytological sampling is safe and effective for the diagnosis and planning of management of focal pancreatic lesions, especially pancreatic cancer.
