Acute Pancreatitis after Double-Balloon Enteroscopy: An Old Pathogenetic Theory Revisited as a Result of Using a New Endoscopic Tool

Abstract

Double-balloon enteroscopy is a novel technique for visualizing the entire small bowel. Complications have been reported relatively rarely in the small series published up until now. In this report we describe two patients who developed acute pancreatitis immediately after double-balloon enteroscopy, diagnosed on clinical, biochemical, and radiological grounds. In both patients the pancreatitis resolved with supportive care. Based on early studies on the pathogenesis of acute pancreatitis, we discuss the possible pathogenetic mechanism for pancreatitis arising as a complication of this novel endoscopic technique.
