Sutureless Compression Anastomoses Formation with Use of TiNi Device on the Small Gut
Abstract
A new device made of nickelid titanium and a way of formation of a sutureless compression anastomosis on the small bowel were developed with the purpose of creating a compression interintestinal anastomosis on the small bowel without the manual portion of seams. 28 sutureless compression anastomosis on the small bowel are created during the experiment. They include 10 «side-to–side» anastomoses, 10 «end-to-end»anastomoses and 8 «end-to-side» anastomoses. Mechanical and biological durability of anastomoses, terms of compression devices failure, primary permeability of anastomoses, morphogenesis of a compression seam are studied. No complications connected with the use of the compression device were noted. During the experiment it is proved that all sutureless compression anastomoses created by means of the nickelid titanium device are mechanically and is biologically tight. By the ninth day all the dogs had no compression devices in their abdominal cavities. The histological researches show that the process of neogenesis goes with the minimal symptoms of sclerosis and leads to the full adaptation of all small bowel layers. The new way of the formation of a sutureless compression anastomosis on the small bowel allowed to create a stronger and more reliable anastomosis and thereby to prevent the development of typical complications and to receive more favorable remote results.
