Choledochocele: Importance of histological evaluation

Recurrent pancreatitis caused by pancreatobiliary anomalies in children with annular pancreas

“…Macroscopically, therefore, choledochocele is quite similar to IDD in communicating with the bile duct, and an accurate distinction between both may be only possible by histologic examination. However, different types of epithelial lining in the inside wall have been reported; the epithelium is mainly composed of duodenal mucosa in children, whereas biliary and undifferentiated epithelial cells are predominant in adults [23,24]. These findings suggest that choledochocele is closely related to IDD in children, and we consider Fig.…”

Stone-containing periampullary duodenal duplication cyst with aberrant pancreatic duct

“…The spectrum of cystic lesions also includes intramural dilatations of the dorsal pancreatic duct (Santorinicele) [2]. Furthermore, different variants of choledochal cysts, which are a malformation of the intraduodenal part of biliaropan- creatic ducts, are reported in the literature [8][9][10]. To our knowledge, the described malformation in combination with stone formation (Fig.…”

Periampullary choledochal diverticula are not choledochal cysts

“…3,9,[19][20][21][22][23] PCD were defined as small, saccular outpouchings of the CBD, at the superior margin of the biliary sphincter.…”
