Pig small intestine should be edible, but after operation, spicy food should be avoided and anal care should be done well. The muscles and tissues in the anus grow slowly, and it takes at least one month from operation to complete recovery. After defecation, make sure the anus is clean and clean it with running water. Because the anal wound hurts when touched, it can't be wiped with paper at all. Moreover, wiping with paper will only wipe the stool into the folds and wounds of the anus, leading to bacterial reproduction and aggravating inflammation and edema. So wash the anus with running water after defecation every time. Some hospitals will give patients after operation an anorectal rehabilitation suit, which contains a hand-held washing clothes, and the anus can be washed with clear water after defecation. If you don't want to return to the palace after discharge, you should take it with you when you go out to work, and rinse it after each defecation. Be sure to follow the doctor's advice strictly, otherwise recurrence will be in trouble.
