RESUMO
Objective To evaluate the diagnostic value of endoscopic ultrasonography (EUS) guided fine needle aspiration (FNA) in patients with suspected chronic pancreatitis. Methods Forty seven patients including 28 males and 19 females (mean age 52.3 years, range 47～69 years) were enrolled into study. The diagnosis of chronic pancreatitis or pancreatic malignancy was based on results of BT PABA test, Sudan Ⅲ staining of stool and abdominal CT scanning, the mean course of disease was 6.3 year (range 3 21 year). Pancreatic tissue specimens were harvested by EUS guided FNA and investigated by histopathological study. Results Totally 31 cases (31/47, 69%) were diagnosed as chronic pancreatitis based on histopathological examination of the specimens taken by EUS FNA. Conclusion EUS FNA had the potential clinical value in diagnosis of chronic pancreatitis.
