About reconstruction of the pharynx with colon in extensive corrosive strictures.

The author presents a series of 235 esophagocoloplasties, in 90 cases a pharyngeal reconstruction being performed. The colic graft was anastomosed to the hypopharynx in 43 cases, to the oropharynx in 14 cases, and in 33 cases a pharyngoplasty was done. A personal classification of the approach of the pharynx according to local innervation is attempted, and various original procedures of pharyngeal reconstruction are described (double pharyngoplasty "en Y", pharyngoplastia "vera"). A great effort was made in preservation of the larynx, which remains the main aim of the author.
