Endobronchial suture. A foreign body causing chronic cough.
Although rarely considered in series of lower airway foreign bodies, endobronchial sutures can cause chronic cough or hemoptysis years after thoracic surgery. Eight endobronchial sutures were found in six patients who had undergone surgery four to 30 years prior to admission. Symptoms began two to 25 years after surgery and lasted from two to six years prior to diagnosis. Cough had been attributed to chronic bronchitis or bronchiectasis in five patients and to tracheal narrowing secondary to surgical repair of tracheomalacia in the sixth. Bronchoscopy was diagnostic in all cases. Suture removal was performed with either forceps or endoscopic suture scissors to cut the suture followed by extraction with forceps. Symptoms resolved within three days and granulation tissue by two to four weeks after suture removal. This series suggests that endobronchial suture should be considered in patients with a history (even remote) of previous thoracic surgery who present with chronic, persistent cough unresponsive to specific therapy for any underlying pulmonary disease.
