New options for aerodigestive tract replacement after extended pharyngolaryngectomy
1Department of Clinical Physiopathology, I Ear Nose and Throat Clinic, Azienda Ospedaliera S Giovanni Battista, Turin, Italy.
Objectives:
Assess the results of a new type of reconstruction of the aerodigestive tract after extended pharyngolaryngectomy.
Study Design:
Follow-up of a total of eight patients who had surgery using ileocolic free graft.
Methods:
The surgical technique is described. Five patients underwent pharyngolaryngectomy/cervical esophagectomy, and three patients had total laryngectomy with subtotal pharyngectomy. Patients were monitored to assess complications and recovery of satisfactory swallowing and speech.
Results:
The technique, thanks to the use of material from the colon, proved to be extremely useful for the reconstruction of the digestive tract. At the same time, ileal anastomosis with the tracheal stump enabled aerodigestive crossing restoration, protected by the ileocecal valve. All patients recovered good swallowing capacity and phoniatric expression, which were obtained by digital occlusion of the tracheostomy, forcing the expiratory air through the ileum and ileocecal valve. Manometric tests also showed that after a while there was a gradual synchronization of swallowing between the transplanted colic segment and the residual esophagus.
Conclusions:
The technique described in the present study may be regarded, also in the light of possible further applications, as a new and interesting option for the reconstruction of the aerodigestive tract.
