OBJECTIVE: The aim of this study was to determine the utility of endoscopic ultrasound (EUS) in patients with unexplained acute pancreatitis, and whether endoscopic retrograde cholangiopancreatography (ERCP) is subsequently needed. METHODS: Subjects who underwent EUS for assessment of idiopathic acute pancreatitis were identified, their medical records were reviewed, and they were contacted for a follow-up telephone interview. EUS diagnosis was compared with the final diagnosis and outcome. RESULTS: EUS revealed a cause of pancreatitis in 21 of the 31 subjects (68%), including microlithiasis in five (16%), chronic pancreatitis in 14 (45%), pancreas divisum in two (6.5%), pancreatic cancer in one (3.2%), and was not diagnostic in 10 (32%). During a mean follow-up period of 16 months, diagnosis changed in four subjects (13%), and nine subjects (29%) had ERCP because of persistent symptoms or recurrent pancreatitis. CONCLUSION: EUS, a less invasive test than ERCP, demonstrated an etiology in two-thirds of patients with idiopathic acute pancreatitis. Most patients did not require ERCP during the follow-up period. EUS can be an alternative to ERCP in patients with unexplained acute pancreatitis.
