Macrocolon is able to defecate on its own. This is due to a lack of ganglion cells in the colon, which leads to secondary hypertrophy and dilatation of the nearby colon. The main manifestation is a widening of the colon, which can cause diarrhea and difficulty in defecation to a certain extent. In addition, the child’s autonomy is still weak, which may lead to abnormal bowel movements, such as temporary inability to defecate. The child can be treated with an anal enema or an open plug, or he can be treated with anal dilation. However, it can only temporarily relieve the symptoms of megacolon, but not completely cure it. You need to go to the hospital for further examination, and then according to the diagnosis, then targeted treatment, if necessary, also need to carry out surgery.
