Cholecysto-choledochal fistula--Mirizzi syndrome (type II) in a Nigerian.

Abstract

Mirizzi syndrome is an uncommon cause of obstructive jaundice in which the common hepatic duct is obstructed by stones trapped within the neck of the cystic duct of the gall-bladder. In long standing cases the calculi may erode through into the common duct and may in fact, impact in the resulting fistula. This syndrome with its later progression is a rare complication of calculous disease of the gall-bladder worldwide. While it is perhaps encountered in the developing countries where cholelithiasis is not as prevalent as in the affluent countries, there has not been much documentation. This article reports on a Nigerian patient with a fistulous complication of Mirizzi syndrome (Type II) managed by cholecystectomy and choledochoduodenostomy and also presents a discussion of the condition.
