Role of EUS-FNA and percutaneous US-FNA in diagnosis of pancreatic head lesions, Egyptian experience

ABSTRACT

Pancreatic carcinoma is one of the leading cancer morbidity and mortality worldwide. Endoscopic Ultrasound [EUS] provides good direct visualization of the pancreas and EUS-FNA raises the accuracy for diagnosing pancreatic malignancies. US-FNA is another established method for diagnosing pancreatic malignancies. To determine the Role of Percutaneous US-FNA and EUS-FNA in diagnosis of pancreatic lesions. 131 patients with pancreatic masses were included in the study and sub-classified into 2 groups according to the imaging tool used, US-FNA [group I] and EUS-FNA [group II]. Using the appropriate statistical tools, sensitivity, specificity, positive predictive value [PPV], negative predictive value [NPV] and diagnostic accuracy were calculated for both groups. It was 88.2%, 93.9%, 96.8%, 97.5% and 90.1% respectively in group I. It was 77.8%, 100%, 100%, 75% and 86.7% respectively in group II. US-FNA/EUS-FNA are safe reliable tools for diagnosis of pancreatic lesions
