The aim is to evaluate the peak secretory flow rates and bicarbonate concentrations as determined by a 30 minute intraductal secretin stimulation test in patients with a low likelihood of pancreatic pathology and to compare these data to those obtained from our historical patients with suspected chronic pancreatitis. These will be patients in which inadvertent pancreatic cannulation occurs during therapeutic endoscopic retrograde cholangiopancreatography (ERCP) for biliary indications . All study subjects will receive a 5 day follow-up phone call. Enrollment goal is 36 subjects.
