Abstract
Postcorrosive strictures of the upper aerodigestive tract are serious complications of caustic injury. In case of development of extensive strictures or necrosis, it is usually necessary to perform a resection of the damaged part of the digestive tract with a restoration of the continuity of the swallowing pathways by autologous material.
Simultaneous involvement of the hypopharynx and esophagus makes subsequent treatment very difficult, because the reconstruction of this area interferes with swallowing and breathing. If the replacement is required, it is technically easier to perform total laryngectomy and resection of the affected part of the swallowing tract with subsequent reconstruction.
Morbidity associated with total laryngectomy is generally unacceptable for patients without corrosive laryngeal injury. Therefore, the technique of colopharyngoplasty has been developed.
A 35 years old patient swallowed hydrochloric acid in a suicidal attempt. Esophagectomy with cervical esophagostomy and total gastrectomy was performed urgently.
The patient was indicated for delayed reconstruction of the swallowing tract. Due to the fully preserved larynx, reconstruction of the hypopharynx and esophagus was performed by colopharyngoplasty technique without laryngeal resection.
After intensive rehabilitation of voice and swallowing, successful decannulation was performed and full oral intake was restored.
