[Special aspects of colo esophagoplasty in post-caustic esophageal stenosis for corrosive stricture of the esophagus (author's transl)].

The author reports 12 cases which illustrate unusual aspects of colo esophagoplasty in post-caustic esophageal stenosis. 8 cases respresented post-caustic pharyngolaryngeal stenosis in which he recommended anastomosis of the colon with the oropharynx according to a personal technical variant. In 1 case associated with amputation of the epiglottis, he carried out a double pharyngo-colic Y-shaped anastomosis. He classified the pharyngotomy types in relation to the 3 main nerves, the lingual, hypoglossal and superior laryngeal nerves. In 3 cases the author carried out successfully retrosternal transposition of a colonic segement 6 months, 1 year and 4 years after pre-thoracic colo esophagoplasty. He reports 1 case of intrathoracic strangling of the colonic tube which occurred 1 year after retrosternal colo esophagoplasty, and wich was cured by intra-vascular vertical clectomy. In all cases the good results were maintained for a long period.
