[Polarographic evaluation of oxygen metabolism in the transplant after esophagogastroplasty].

Oxygen metabolism of a tube graft formed from the greater curvature of the stomach in esophagoplasty for carcinoma of the thoracic esophagus was studied by polarography. The study was conducted during the stages of treatment: in the early postoperative period and before the formation of a postponed extracavitary esophagogastric anastomosis. Oxygen tension (pO2) and the rate of oxygen consumption (ROC) by the graft tissue were studied. The pO2 for the isoperistaltic grafts was 65.3 +/- 2.31 mm Hg in the zone of the nutrient vessel and 51.68 +/- 11.6 mm Hg in the zone of the mechanical suture. A favourable postoperative period corresponded with a ROC of 0.1-0.2 units. The results of the study coincided with the clinical result in 86.3% of cases.
