[Circular intestinal and esophageal suture with universal suture device (experimental trial)].
A universal suture device (USD) able to make simultaneous two-line and cross-shaped circular clips stitches on various tube-shaped organs (vessels, intestines, esophagus, stomach, ets), creating end-to-end and end-to-side anastomosis with the external cuff is proposed. The results of experimental trials of USD and its clinical use in anastomosing main vessels were published before (8, 9, 11, 12). In this article the results of experiments with the use of USD in intestinal and esophageal sutures in 35 dogs are analysed. There were 4 series of experiments with 45 anastomoses (31 intestinal and 14 esophageal anastomoses). The anastomosed segments of the intestines and esophagus healed at the level of the lower side of the cuff. The cuff completely resumes its shape in 2.5-5 months, and the clips come off by month 7-8 after the surgery. The mucous layer of the esophagus straightened by the 2-3d month, while adventitial-muscular layer does not straigheten at all, and the clips from it could be found till the 10th month after the surgery. There were no cases of anastomotic incompetence.
