Endoscopic submucosal dissection-based suture combined with medical adhesive for complicated tuberculous bronchoesophageal fistula: a case report.

Tuberculous bronchoesophageal fistula is a rare complication of tuberculosis. Herein, we report the case of a woman in her late 60s with a choking cough for more than 1 month. Iohexol esophagography revealed a fistulous communication between the esophagus and the right principal bronchus, and gastroscopy documented a fistulous orifice in the esophagus. Endoscopic closure with metal clips failed, and other treatment options, such as extended conservative treatment, covered self-expandable metal stents, and over-the-scope clips were rejected by the patient. Therefore, a combined therapy, endoscopic submucosal dissection-based suture combined with medical adhesive, was performed. Follow-up iohexol esophagography and gastroscopy confirmed fistula closure. During 1 year of follow-up after discharge, the bronchoesophageal fistula did not recur. Endoscopic submucosal dissection-based suture combined with medical adhesive appears to be a practical and feasible solution to complicated tuberculous bronchoesophageal fistula.
