Direct Insertion of a Dumon Stent Into an Intermediate Bronchus Fistula From the Surgical Field

A 54-year-old man underwent right S6 segmentectomy for right lung cancer. After discharge, he presented with fever, hemoptysis, and cough, and computed tomography showed an intermediate bronchus fistula. Because direct closure or bronchoplasty was challenging, a Dumon (Novatech) stent was inserted directly into the fistula from the surgical field and covered with an autologous pericardial patch, pedicled mediastinal fat, and intercostal muscle. The Dumon stent was removed by rigid bronchoscopy 1 year later. For an intermediate bronchus fistula that was difficult to repair by bronchoplasty, a Dumon stent was effective for maintaining bronchial patency and preserving the peripheral lung.
