Objective: To analyze our ten year experience of surgical treatment of children with chronic colonostasis of different origin. Material and methods: The study covers 353 children aged from 1 day to 17 years with colonic stasis who undergo treatment at the Department of Children's Surgery, Bukovinian State Medical University, Cernau.i, Ukraine. Study design included case history, physical examination, routine clinical and biochemical laboratory tests, endoscopy (sigmoidoscopy, colonoscopy), X-ray (irrigoscopy, irrigography, other radiopaque techniques) methods, and sphincterometry. Results. Non-surgical treatment was effective in 261 (73.94 %) patients. The group of the operated patients consisted of 92 (26.06 %) children. The outcome of surgical treatment of Hirschsprung's disease (49 children), dolichosigmoid (29 children), Payr's disease (12 children), and Chilaiditi syndrome in all cases is considered to be satisfactory. The optimal methods of surgical operations are offered according to pathology of colon. Conclusions: One-step Soave- Boley operation is considered to be the method of choice for rectal and rectosigmoid forms of Hirschprung's disease. Transversal colon resection and phrenico-colic ligament dissection in Payr's disease, hepatopexia and right colon fixation in Chilaiditi syndrome are effective treatment approaches.
