An evaluation of endoscopic retrograde pancreatography (ERP) in chronic and relapsing acute pancreatitis.

The results of ERP carried out in a series of cases of established and suspected chronic and acute relapsing pancreatitis are presented. Radiological findings are divided into major and minor alterations of the pancreatic secretory system. X-ray findings are easy to interprete in chronic pancreatitis with major alterations. Minor anomalies of the pancreas are difficult to interprete in the absence of supporting evidence. Biliary tract involvement is useful for diagnosis of chronic pancreatitis.
