Abstract. Comparative analysis of surgical treatment results of 2 groups of patients: group 1 ― patients with plasty of the esophagus gastric stem with the imposition of esophagogastrostomy on the neck (138 patients), 2 group ― patients with plasty of esophagus with whole stomach with the formation of esophagogastrostomy in the right pleural cavity with the use of circular suturing apparatus (38 patients). For comparison, the following methods of investigation were used: intraoperative wall photoplethysmography, x-ray and radioscopy of the artificial esophagus and endoscopic pH-metry. Because of the study, the following conclusions were obtained: 1) The developed device and method for measuring intraoperative blood supply allows to estimate the intramural blood flow of the artificial esophagus with a high degree of accuracy. 2) There was no statistically significant difference in the x-ray picture of the evaluation of motor-evacuation function of gastric graft in the study groups. 3) During the endoscopic examination in combination with pH-metry revealed that patients of the study group are more likely to suffer from hypo- and anacid state of gastric graft.

Key words: esophageal cancer, artificial esophagus, esophagoplasty, diseases of artificial esophagus.
