Ulcerated choledochocele: A case report

The cystic dilatation of the biliary tract is an uncommon anomaly. Choledochocele, a cystic dilatation of the distal common bile duct, rarely presents clinically as massive gastrointestinal bleeding.

This is to report a very rare disease condition and highlight minimal access options in surgical care.

A 13 year-old boy was referred with a day history of sudden onset of passage of bright red blood per rectum with a fainting episode. There was no anal protrusion, jaundice, recurrent epigastric pain nor bleeding from any other orifice. An initial endoscopic assessment of the upper digestive tract showed profuse bleeding from a sub-mucosal mass in the region of ampulla of Vater. Emergency laparotomy revealed small intestine filled with blood from duodenum to ileum. A duodenotomy showed a cystic mass with an ulcerated mucosa at the dome containing bilious fluid in the second part of the duodenum. The cyst was de-roofed and marsupialized. Post-operative recovery was complicated by features of adhesive small bowel obstruction on the 9th post op day and treated by laparoscopic adhesiolysis. He was discharged home in good clinical state.

Choledochocele is a differential diagnosis in the endoscopic finding of a submucosal mass in the second part of the duodenum. An initial oesophagogastroduodenoscopy endoscopy is necessary in the evaluation of massive lower gastrointestinal bleeding.
