High incidence of tracheobronchial diverticulum in esophageal cancer patients: a retrospective survey alerting pitfall during thoracoscopic esophagectomy.

If a tracheobronchial DV is injured during surgery, it is important to carefully repair it and confirm that there is no air leak to avoid complications.
