title: [Congenital diverticulum of the lower choledochus. Apropos of a case with intraduodenal development].
abstract: The onset of subicterus in a patient revealed the presence of a congenital diverticulum of lower common bile duct of intraduodenal development. A part from the rarity of this lesion this case is of interest due to the complete range of ultrasound, endoscopic and CT scan imaging performed, the association of a common mesentery and the surgical technique employed. The latter comprised exeresis by transduodenal approach and a side-to-side choledocho-duodenal anastomosis through the intermediary of the diverticular sleeve. The nosology and differential diagnosis of diverticulum of lower common bile duct are discussed and data from a literature review used to describe diagnostic, etiopathogenic and histopathologic aspects as well as complications and treatment of this type of congenital dilatation of lower biliary tract.
