Spontaneous closure of a large tracheal fistula due to descending necrotizing mediastinitis

We present a case of a 77-year-old man who had a large tracheal fistula due to descending necrotizing mediastinitis. He underwent long-term care with a respirator after mediastinal drainage operations. The fistula was covered spontaneously with the anterior wall of the esophagus 1.5 months postoperatively.
