Common hepatic duct obstruction by remnant cystic duct stone after cholecystectomy: Mirizzi syndrome

The Mirizzi syndrome is an uncommon cause of obstructive jaundice. In 1948, Mirizzi characterized a syndrome in which common hepatic duct obstruction occurs because of impacted stones in the gallbladder neck or cystic duct. It is commonly referred to date as the Mirizzi syndrome. Patients with lower insertion of the cystic duct and a long parallel course of cystic duct and common hepatic duct are often left with a long cystic duct remnant after cholecystectomy. The remnant may gradually increased in size and become a site of bile stasis, chronic inflammation, and stone formation. We report a case whose obstructive jaundice after laparoscopic cholecystectomy results from residual stone in the cystic duct remnant.
