Type III (choledochocele)

The choice of therapy depends upon the size of the cyst. Choledochoceles measuring 3 cm or less can be treated effectively with endoscopic sphincterotomy. Lesions larger than 3 cm typically produce some degree of duodenal obstruction. These lesions are excised surgically through a transduodenal approach. If the pancreatic duct enters the choledochocele, it may have to be reimplanted into the duodenum following excision of the cyst.
