Covered self-expandable metallic stent placement for tumor bleeding from duodenal invasion in patients with unresectable pancreatic cancer

Abstract

Patients with unresectable pancreatic cancer often present with duodenal bleeding, a potentially life-threatening complication. In our case series of six unresectable pancreatic cancer patients with tumor bleeding, we explored the efficacy and safety of placement of a covered self-expandable metallic stent in the duodenum as a treatment option; we achieved a hemostasis rate of 67% (4/6), with a rebleeding rate of 50% (2/4). No complications occurred with stent placement, except for food impaction in one patient. Covered self-expandable metallic stent placement is a moderately effective treatment option for tumor bleeding in patients with unresectable pancreatic cancer. Although its hemostatic efficacy is limited, covered self-expandable metallic stent placement is safe and beneficial in some cases, warranting consideration in this disease setting with limited treatment options.
