Anorectal malformations (ARMs) occur with the incidence of 1:5000 live births, and have various clinical manifestations. Considerable progress have been made in the management of children with ARMs over the past 20-30 years, both in terms of surgical technologies and in achieving good functional outcomes. However, despite all the technical advances in surgical management of ARMs, still there are complications that require re-operation. Constipation and incontinence are major problems of the postoperative period that require examination. Indications for re-operation are based on the MRI results, visual examination with electro-myographic signals detection, X-ray examination; depend on the type of specific pathology and require individual management approach.
