[Comparative evaluation of various types of intestinal sutures in newborn infants and young children].

The article deals with the results of experimental and clinical studies. The mechanical strength of the coats of the intestinal wall was tested in cadavers of newborns and on basis of the findings a variant of a single-layer +sero-muscular-submucous intestinal suture was suggested. It was studied later in comparison with other types of sutures in experiments on 140 immature rats. All sutures were applied by microsurgical techniques. The results of the clinical use of the suggested suture in newborns and infants were analysed in comparison with previously applied sutures. Four groups were set apart: 1st--double-row interrupted suture (45 patients); 2nd--single-row suture applied at the edge through all coast (15); 3rd--Mateshuk's single-row suture (7); 4th--single-row +sero-musculo-submucous suture applied by microsurgical techniques (32). Complications were revealed on the part of the anastomosis: 1st group--24 (53.3%), 2nd group--11 (73.3%), 3rd group--4 (57.1%), 4th group--1 (3.1%). The results of macro- and microscopic study of the anastomoses in fatal cases suggest that the +sero-musculo-submucous intestinal suture provided the most favourable conditions for healing of the anastomosis.
