Three years and 6-month long secondary patency of covered-metal stent for ampullary carcinoma: A case report

Abstract

The patient was a 78-year-old man admitted to our hospital because of ampullary carcinoma. Surgery was not feasible and thus he underwent stenting using a covered metal stent (CMS). A second CMS was added 4 months later due to tumor ingrowth and sludge formation at the duodenal end of the first stent. The duodenal end of the second CMS was placed toward the inferior duodenal angle, and the stent was patent for 3 years and 6 months.
