Authors report on 3 cases of children treated by therapeutic endoscopic retrograde cholangiopancreatography for pancreatitis (ERCP). The first child presented with familial pancreatitis: he was treated by sphincterotomy and lithiasis extraction. The second child presented with pancreatitis secondary to pancreas divisum: she was treated by sphincterotomy and stunt of small caroncula. The third child presented with severe pancreatitis with pseudocyst: after drainage she was treated by sphincterotomy, Wirsung dilatation and lithiasis extraction. ERCP is a beneficial treatment and may be alternative to surgery in complicated pancreatitis.
