[Dynamics of the morphological changes in a colonic autotransplant during experimental plastic surgery of the cervical esophagus].

In the experiment on 16 dogs, the morphologic structure of a colonic autotransplant utilized for restoration of a total defect of the cervical esophagus was studied. A segment of the descending colon with terminal inferior mesenteric vein and ostium of the inferior mesenteric artery with a part of the aortic wall was used. Reformation of the intestinal epithelium was noted. By day 21 after the operation, a multilayer squamous epithelium was revealed in the intestinal autotransplant, in the muscular layer--structures of the forming neuromas. No esophageal stenosis was noted.
