Generally, the laxatives we use for constipation act on the intestinal tract, only the corkage is used for the anal opening. Two conditions suggest treatment with cork; 1, the patient’s stool is soft or thin 2, the balloon forced out test positive, that is, can not expel the balloon The problem of the anal opening should not force defecation, and should not be forced to hold the stool. With the intention to defecate, do not worry too much even if you cannot defecate immediately i.e. do not hold the stool too hard (unless you cannot hold it with diarrhea). The essence is that the anal sphincter is too tense, and if you force it, it is even more tense. Appearing to defecate is not to force force defecation, it is recommended to use a bit of cork or a little oil (edible sesame oil at home) enema 10 ml, you can buy a small Sakai bottle of eye drops, squeeze out the eye drops, and then use its pumping oil.
