[Unusual aspects of colo-esophagoplasty in post-caustic esophageal stenosis].

The author presents 7 cases illustrating various particular aspects of coloesophagoplasty performed in cases of post-caustic esophageal stenoses. In pharyngolaryngeal stenoses the author recommends a personal technical variant of the oro-pharyngeal anastomosis. In one such case he performed a double pharyngocolic anastomosis in "Y". In two cases the author has successfully carried out retro-sternal transposition "of necessity", at 6 months and 4 years after coloesophagoplasty in the pre-thoracic variant. Intra-thoracic strangulation of the colic tube, occuring in two cases at 1 and 3 years respectively following initial surgery was resolved by colectomy of the intra-vascular type ("of verticalization").
