BackgroundIn patients with Hirschsprung's disease (HD), persistent obstructive symptoms may develop after surgery. The causes of mechanical obstruction may be a retraction of the pulled-through bowel due to insufficient mobilization of the mesentery or impaired blood supply in the area of the coloanal anastomosis in the case of excessive ligation of the supplying vessels. Leakage and stenosis are formidable complications and require repeated surgical intervention.ObjectiveThe purpose of this study is to describe our experience and short-term results of the developed method: mobilization of the descending colon for its pull-through during the surgical treatment of the children with HD, which allows ensuring good mobility to the descending colon and maintaining blood supply at the same time.MethodsThe medical records of 20 patients with rectosigmoid HD, who underwent parietal mobilization of the descending colon with preservation of the marginal artery, sigmoid arteries, and ligation of the left colon artery, were reviewed. This method is aimed at increasing the mobility of the brought-down bowel and maintaining the blood supply to the distal part of the brought-down bowel not only from the superior mesenteric artery but also from the lower one.The SPSS Statistics 26.0 package was used for statistical analysis. To describe the analyzed data with a normal distribution, the mean values and the error of the mean were used. To determine the differences, Student’s t-test was used, and the differences were considered significant at a significance level of p < 0.05.ResultsIn all patients, the postoperative period was uneventful, without complications. The patients were discharged for outpatient treatment on average on the seventh day after the surgery. In all cases, there were no signs of anastomotic leakage or stricture on follow-up after 6–12 months.ConclusionThe method of mobilization of the colon in the rectosigmoid form of HD, parietal mobilization of the descending part of the colon preserving the marginal artery, sigmoid arteries, and ligating the left colon artery, can reduce the risk of complications by eliminating the tension of the descending colon.
