[Clinical experiences with the insertion of Dumon-type endotracheal stent tube for the patients with tracheal stenosis due to advanced esophageal carcinoma].

To relieve tracheal stenosis due to esophageal carcinoma, we have inserted Dumon-type endotracheal stent tube to 2 patients with stenosis of the left main bronchus and a patient with tracheal stenosis. Severe dyspnea and stridor found in these patients was much improved in all three cases. After insertion of the stent tube to 2 patients with stenosis of the left main bronchus, radiation therapy with the dose of 65 Gy to main esophageal lesion was undergone, which resulted in the partial remission. These management allowed the patients to discharge. The last case with tracheal stenosis was due to recurrence of the esophageal carcinoma, which required additional insertion of the stent tube at the proximal site after initial insertion in a short period. We conclude that the quality of life and prognosis of patients with tracheal stenosis due to advanced esophageal carcinoma may be improved by the insertion of Dumon-type endotracheal stent tube.
