Endoscopic Placement of Metal Stents in Treating Patients With Cancer- Related Duodenal Obstruction
A Pilot Phase I/II Trial of Enteral Wallstents for Duodenal Obstruction in the Setting of Malignancy

RATIONALE: The use of endoscopy to place metal stents in the duodenum is less invasive than surgery for treating cancer-related duodenal obstruction and may have fewer side effects and improve recovery.

PURPOSE: Phase I/II trial to study the effectiveness of endoscopic placement of metal stents in treating patients who have cancer-related obstruction of the duodenum.


  • Determine the objective response and clinical outcome in patients with duodenal obstruction secondary to malignancy treated with enteral Wallstents.
  • Evaluate the efficacy and safety of this treatment in these patients.
  • Evaluate the quality of life of these patients after enteral Wallstent placement.

OUTLINE: Patients undergo enteral Wallstent placement through an endoscope under fluoroscopic guidance into the duodenum.

Quality of life is assessed at 48 hours and 6 months after procedure.

Patients are followed at 48 hours, 30 days, 6 months, and then yearly thereafter until death.

PROJECTED ACCRUAL: A total of 20 patients will be accrued for this study.
