After surgery, patients expect to be pain-free! They expect to be able to go to work the next day! But the anus can’t rest after the surgery, so they have to work hard every day (defecation)! And the perianal skin is sensitive to external stimuli! More or less will still be a little discomfort! Patients are advised not to challenge their limits! When it is time to change the medication, it is time to rest! But from the details of the improvement, theoretically can be achieved without pain! First of all, remember to cleanse the enema before surgery, so that you can avoid the immediate post-operative solution of stool. Secondly, it is best to have a liquid or semi-liquid diet for the first three days after surgery to keep the bowels open and avoid excessive frictional pressure during defecation! Then again, before defecation can be appropriate to use some pain ointment, which can solve the urgent needs! Of course, the most important thing is surgery! Before the operation, you can moderately dilate the anus, the post-operative anal pressure will not be too large, a small action can greatly reduce the post-operative patient’s pain! Secondly, when designing the surgery, try to consider the postoperative tension balance, do not let the local tension is too large! Then again, try to keep the operation mouth drainage smooth, the sewer is open, there is no discomfort above!
