[АNORECTAL DYSFUNCTION, OCCURRING AFTER SURGICAL TREATMENT OF HIRSCHPRUNG'S DISEASE AND ITS CORRECTION].

ABSTRACT

Results of examination and treatment of 12 children, operated on in various clinics for Hirschprung's disease, in whom chronic constipation and other signs of anorectal dysfunction have occurred, were analyzed. In 8 patients Duhamel-Bairov operation was conducted, in 2 ­ Soave-Lenyushkin operation, and in 2 ­ Soave-Boley operation. The main cause of postoperative chronic constipation occurrence after Duhamel operation is the colorectal septum preservation. The only one radical method of treatment of this complication is a transanal removal of colorectal septum. The cause of anastomotic narrowing after Soave-Boley operation was absence of myotomy intraoperatively and of bougienage ­ after it. Elimination of chronic constipation in such patients, using long-standing bougienage and complex conservative treatment. The main cause of chronic constipation and nocturnal encopresis after Soave-Lenyushkin operation was preservation of the tissue excess while doing resection of a large bowel stump and creation of the narrowed ring, looking like a pendent plica. Complete reconvalescence of such patients is possible in transanal method of excision of stenosing ring and conduction of complex treatment.
