Chronic pancreatitis is a progressive inflammatory condition where progressive fibrosis and calcification results in loss of physiological pancreatic function (both endocrine and exocrine). The structural, fibrotic changes of chronic pancreatitis can only be seen in advanced disease with conventional radiology tests and the diagnosis of chronic pancreatitis early in the disease course remains challenging. Early diagnosis and treatment of chronic pancreatitis can prevent the complications of pain and malnutrition and improve the quality of life of patients. Endoscopic ultrasound (EUS) has recently become a favoured method for diagnosing early structural fibrotic changes of chronic pancreatitis in clinical practice; however this technique is subjective with sub-optimal intra-observer agreement. A new technique called elastography, performed during EUS, quantitatively measures tissue stiffness which may give more reliable results. This study aims to assess whether EUS elastography can accurately identify for chronic pancreatitis.
