Endoscopic repair of laryngotracheoesophageal clefts

Background/PurposeIn Japan, surgical repair of a laryngotracheoesophageal cleft (LTEC) typically consists of the anterior approach, with the lateral approach as an alternative. Endoscopic surgery to repair the tracheoesophageal septum has been reported, and this study reviewed our experience treating several cases of LTEC endoscopically.MethodsEndoscopic repair of LTEC was performed in 7 patients (3 boys, 4 girls; age range 4 months to 2 years 10 months; mean age 11 months; mean weight at surgery 7.23 kg; weight range 3.85–12.24 kg) between 2009 and 2014. LTEC was type I in 5 patients and types II and IV in 1 patient each. The patient with type IV was first operated on by the lateral approach, and the remaining cleft, which level was type III, was repaired endoscopically. Postoperative outcomes were retrospectively studied.ResultsEndoscopic surgery was successful in all patients. All 6 patients with types I and II LTEC were extubated easily, while in the patient with type IV LTEC, it was difficult to remove the tracheostomy cannula because of tracheomalacia. Postoperatively, tracheostomy cannulation became more stable, and the patient is gradually being weaned off the ventilator. All patients could be fed orally without difficulty postoperatively.ConclusionsEndoscopic surgery provides a view from the cephalic aspect permitting the surgeon to form a normal larynx with only minimal risk of complications.
