Coloesophagoplasty is indicated to children with oesophageal atresia and tracheoesophageal fistula or without it and with cicatrical or peptic oesophageal stenosis. Retrosternal coloesophagoplasty is performed in compliance with certain main principles, viz. isoperistaltic graft on the left colic artery, formation antireflux anastomosis with the stomach, graft length exactly matching the distance between anastomosis on the neck and the stomach. The severity of the postoperative period depends on the extent and the mode of surgical intervention, graft characteristics, oedema in the region of proximal anastomosis, unstable hemodynamics, intestinal paralysis, and infectious complications. In the postoperative period, artificial lung ventilation gradually gives way to spontaneous respiration, infusion therapy, parenteral nutrition, anesthesia according to a newly developed scheme and finally to enteral feeding. The study revealed peculiarities of preoperative and postoperative treatment in children undergoing coloesophagoplasty. It included comparative analysis of the number of patients, duration of artificial ventilation, and extubation time at the early and current stages of development of this surgical strategy.
