Hilar Malignant Biliary Obstruction Treated with Four Metallic Stents Involving a New Slim Device
Abstract
Endoscopic hilar multiple stenting is challenging. A 68-year-old patient had self-expandable metallic stents (SEMSs) inserted for unresectable hilar malignant biliary obstruction. After the SEMSs were inserted into the left hepatic duct and bile duct branch of segment (B) 6, a new SEMS with a wide mesh and slim delivery system was inserted into the right anterior hepatic duct. However, liver abscess and dilated B7 were observed on computed tomography; therefore, an additional new SEMS was quickly and easily inserted into B7. After the placement of these four SEMSs, the liver abscess improved. The new SEMS was effective for hilar multiple biliary drainage.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
