Iatrogenic Tracheal Posterior Wall Perforation Repaired with Bronchoscope-Guided Knotless Sutures Through Tracheostomy.

A 68-year-old man presented with a posterior tracheal wall injury caused by percutaneous dilatational tracheostomy. The wound was immediately covered with an absorbable polyglycolic acid sheet. Ten days after the injury, the perforation was closed with knotless sutures using a Castroviejo needle-holder through the tracheostomy. The successful repair in this case indicates the feasibility of the knotless suture technique for perforations. The technique is described in detail in this report. The patient was weaned from the mechanical ventilator on postoperative day 25. In cases of posterior tracheal posterior wall perforation, every effort should be made to repair the perforation through an existing opening.
