BACKGROUND AND AIM: Chronic pancreatitis (CP) is sometimes diagnosed at the progressed stage. For the early diagnosis of CP, Endoscopic ultrasonography (EUS) may be a useful method, but its diagnostic criteria are based on subjective judgement. Shear wave elastography (SW-EG) using transabdominal ultrasonography, which quantifies tissue elasticity as an absolute value, may be an objective and non-invasive method for the diagnosis of CP. METHODS: Eighty-five patients with known or suspected CP who underwent both EUS and SW-EG from October 2012 to July 2016 were included in this study...

BACKGROUND AND AIM: Endoscopic ultrasonography (EUS) and EUS-guided fine-needle aspiration (EUS-FNA) are considered good tools for the diagnosis of pancreatic cancer and for obtaining material for cytology or histology. The accuracy of EUS-FNA can rise to 85-95%, but it is lower in cases with a chronic pancreatitis background or with previous biliary stenting. We aimed to establish the diagnostic yield of the visible length of the core biopsy samples in pancreatic cancer by using one single type of standard 22G needle and to evaluate the factors which can influence the results...
