Anorectal Malformation is a birth defect that occurs while a fetus is developing in the womb. With this defect, the anus and rectum do not develop as they should.Normally, during the digestive process, stool passes from the large intestine to the rectum, then to the anus, and finally the stool leaves the body. Muscles in the anal region help control when we have a bowel movement, and the nerves in the rectum and anus help the brain recognize bowel movements and stimulate bowel movements.
Classification of anorectal anomalies as follows:
Narrow anal canal; The anal opening is covered with a membrane; The rectum is not connected to the anus; The rectum connects to part of the urinary or reproductive tract. Anorectal malformations cause problems with bowel movements and treatment depends on the type of malformation the child has.

5. Treatment
Treatment will depend on the symptoms, severity, abnormalities or comorbidities, and the child's age and overall health. Most children with an anorectal malformation will need surgery to correct the deformity. The type and number of surgeries for each child will be different, it depends on the type of deformity the child has.Parents can start toilet training children at the same age as normal children, from 2 to 3 years old. But for children with anorectal malformations who have had surgery, it may be slower than children because the child may not have good control of bowel movements. Or your child may have chronic constipation. These problems depend on the type of deformity and the type of surgery. Therefore, to help children, parents need to be consulted and guided by doctors.
