FEW WORDS ABOUT PROCEDURE
Main indication to relief of symptoms consistent with airway obstruction from either a malignant or benign obstruction that has failed other medical, surgical, or endoscopic therapies. In malignancy, stents provide excellent sustainable palliation for progressive symptoms in patients whose conditions have been considered terminal. Stent insertion can be an emergent life-saving procedure allowing relief of acute respiratory distress from airway obstruction. It can allow withdrawal from the mechanical ventilator in patients who could not otherwise be extubated.
