[Comparative evaluation of various types of intestinal sutures in newborn infants and young children]
Insights
A novel single-layer sero-muscular-submucous intestinal suture significantly reduces complications. This microsurgical technique offers superior intestinal anastomosis healing in newborns and infants compared to traditional methods.
Area of Science:
- Surgical Innovation
- Gastrointestinal Surgery
- Pediatric Surgery
Background:
- Intestinal suture techniques are critical for successful anastomosis in pediatric surgery.
- Assessing mechanical strength and complication rates of different sutures is essential for improving patient outcomes.
Purpose of the Study:
- To evaluate a novel single-layer sero-muscular-submucous intestinal suture.
- To compare its efficacy and complication rates against traditional sutures in experimental and clinical settings.
Main Methods:
- Mechanical strength testing of intestinal wall coats in cadavers.
- Experimental study on 140 immature rats comparing various microsurgical sutures.
- Clinical analysis of 4 patient groups with different suture techniques, including the novel method.
Main Results:
- The novel single-row sero-musculo-submucous suture applied by microsurgical techniques showed a complication rate of only 3.1% in 32 patients.
- Traditional methods like double-row interrupted sutures had complication rates as high as 53.3%.
Conclusions:
- The single-layer sero-musculo-submucous intestinal suture provides the most favorable conditions for intestinal anastomosis healing.
- This microsurgical technique represents a significant advancement in reducing anastomotic complications in pediatric intestinal surgery.
Abstract:
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.
