Objective:
To study the methods and outcome of surgical management for pharyngo-esophageal stenosis.
Methods:
Twenty-seven patients with pharyngo-esophageal stenosis from January 1983 to June 2001 were reviewed. Among 27 cases, there were 12 cases accompanied with laryngeal stenosis and one case accompanied with tracheal stenosis. In terms of etiological factor, all patients were cataloged into two groups, i.e. 25 cases with chemo-causis and 2 cases with trauma. The repair methods included colon interposition in 20 patients, free jejunum transplantation in 6 patients and pectoralis major muculocutaneous flap in 1 patient. In total 12 cases of laryngeal stenosis, sternohyoid myofascial flap was applied in 8 cases, and sternohyoid myofascial flap and epiglottis were applied in 4 cases.
Results:
Swallow function recovered in 25 cases and failed in 2 cases. Laryngeal function recovered totally in 10 patients and partially in 2 patients with laryngeal stenosis. The patient with tracheal stenosis recovered and decannulated.
Conclusion:
According to the foci of pharyngo-esophageal stenosis, the colon interposition, the free jejunum transplantation and the pectoralis major myocutaneous flap can be applied respectively to restore normal physiological function.
