Abstract: | The vast majority of patients developing obstructive jaundice will have an underlying malignancy. When the etiology of the obstruction cannot be defined prior to operative intervention, identification of a non-malignant process will occur only subsequent to a major operation. The clinical course of a patient with complete distal common bile duct obstruction as the result of pancreatic heterotopia is discussed. This uncommon diagnosis prompted a review of the literature on this subject enabling this detailed discussion inclusive of the embryology, prevalence and clinical presentations of this entity. Our review further identified a varied group of other non-malignant causes of biliary obstruction that may be mistakenly interpreted to represent biliary or pancreatic malignancy. |
