GARCIA-CANO, J. et al. Small size choledochocele as a cause of chronic epigastric pain: diagnosis and treatment by means of ERCP. []. , 22, 12, pp.591-593. ISSN 0212-7199.

Choledochocele belongs to type III Alonso-Lej's classification of biliary cysts and they are considered the less frequent of such cysts. The definition most often given of choledochocele is a cystic dilation of the distal intramural portion of the bile duct, protruding into the duodenal lumen. ERCP is one of the diagnostic and therapeutic procedures of choice, specially when they are small and the cystic cavity is usually collapsed. The ballooning of the papilla during contrast injection in ERCP is thought to be a diagnostic sign. We present a patient suffering from chronic epigastric pain due to a small choledochocele. Magnetic Resonance Cholangiopancreatography failed to diagnose it. ERCP offered both diagnosis and treatment by means of biliary sphincterotomy.
