A 50-year-old woman with upper abdominal pain lasting for more than 10 year.
Choledochocele.
No positive laboratory test results were found.
A 3.0 cm-long, 1.5 cm-wide cystic lesion at the junction of the descending and horizontal portion of the duodenum.
Duodenal mucosa with regional low-grade intraepithelial neoplasia inside the choledochocele.
Open surgical management involving cyst excision with sphincteroplasty.
Choledochocele is considered a rare disease, and cases are seldom reported.
Choledochocele, also known as the type III choledochal cyst according to Todani’s classification, is a cystic dilation of the distal segment of the common bile duct protruding into the duodenal lumen, and accounts for < 2% of all reported cases of choledochal cyst.
Choledochocele is a rare disease and usually misdiagnosed as peptic ulcer. For the choledochocele with large size (i.e., > 3 cm in diameter), we suggest treatment with open surgical management, according to our case’s successful outcome.
