Congenital anorectal malformations and congenital megacolon are common gastrointestinal malformations in pediatric patients. Although surgery can correct anatomical malformations, the quality of life of the child will be affected by whether defecation control can be restored to normal levels after surgery. Interventions for children with fecal incontinence through defecation training can enable them to achieve socially acceptable defecation function at an early age. Defecation training: Dilation training should be started 2 weeks after the anoplasty procedure. Dilation training provides continuous and intermittent dilation of the internal anal sphincter and the spastic rectal segment, effectively stimulating bowel movements; dilation for 3-6 months in children with postoperative anastomotic stenosis is half the battle to ensure successful surgery. Depending on the disease and individual differences, the doctor will recommend the purchase of the type of dilator needed by the child, the first time dilation by the doctor’s guidance, after that follow the doctor’s instructions 1-2 times a day, each time 3-5 minutes, and try to choose the same time every day, so that the child can form biofeedback. The initial model can be increased by one every week if the dilation is smooth, according to the doctor’s prescription. How can parents properly guide their older children in bowel training? 1.Explain to the child the importance of bowel training; 2.No longer supervise the toilet time at all times, let the child choose their own preferred toilet time; 3.Parents should not accompany the child into the bathroom as far as possible (except for the child’s own request for parental accompaniment) 4.Recommend the child to take a squatting position to sit, this position is very helpful for defecation. If the child is small, place a bench under the feet to increase abdominal pressure (anorectal mucosal prolapse is prohibited); 5. Give certain rewards for each child’s bowel training: such as a piece of candy, watching a cartoon, posting a small red flower on the honor roll, a compliment or a warm hug …… 6. 7. Buy your child’s favorite patterned underwear, as he or she may choose to defecate on his or her own to avoid soiling the pattern; 8.
