Another new variant of Bouveret's syndrome.

Although Bouveret's syndrome, i.e. gastric outlet obstruction by a large gallstone impacted in the proximal duodenum secondary to a cholecystoduodenal fistula, is rare, its pathogenesis and clinical features are well characterized. However, existence of variant forms of the syndrome are not well known, and as far as we know, only two cases of variant Bouveret's syndrome have been described in the English-language literature. We present a case of another new variant of Bouveret's syndrome in a 54-year-old Korean woman.
