A case of stenosis of the bronchus caused by invasion of the recurrent esophageal cancer which was treated by endoscopic microwave tissue coagulation and expandable metallic stents

Abstract

A self-expandable metallic stent, Gianturco-Rösch Z-stent (Cook), was used to the patient of the left bronchial stenosis due to recurrent esophageal cancer. The stent was inserted easily with fiberoptic bronchoscopy under local anesthesia, following immediate improvement of atelectasis of the left lung.
After 10 days, it became again obstructed because the tumor grew up through the spaces between the wires. The tumor was easily cauterised and removed by endoscopic tissue coagulation. Thereafter another stent was inserted within the initial stent (stent in stent) to prevent more ingrowth of the tumor. The patency of the airway continued for a few months until the patient deceased from worsening of the general condition.
