Impact of endoscopic ultrasonography on the management of idiopathic pancreatitis

Conventional ultrasonography may fail to detect small stones responsible for acute pancreatitis, leading to a false diagnosis of idiopathic pancreatitis and exposing 33–66 per cent of these patients to the risk of a recurrent attack from untreated gallstone disease. The aim of this study was to assess whether identification of a potential aetiology in patients with ‘idiopathic’ pancreatitis, using endoscopic ultrasonography (EUS), had any effect on outcome.
