The bad effects of getting mixed hemorrhoid surgery include anal stenosis, incomplete anal dilatation, postoperative bleeding, and difficulty in defecation, etc. The probability of getting mixed hemorrhoids varies according to the individual’s physical condition and lifestyle habits, and cannot be generalized. 1. Anal stenosis: If the patient damages too much skin of the anal canal during hemorrhoid surgery, scarring stenosis will be caused after surgery, and anal fissure will occur in severe cases. 2. Incomplete anal sphincter: If the anal sphincter is removed along with the anal raphe muscle during hemorrhoid surgery, it will cause incomplete anal sphincter, which will result in the patient’s anal incontinence and increased frequency of bowel movements. 3. Post-operative bleeding: patients with severe mixed hemorrhoids, who do not take good care of them after the operation, resulting in premature detachment of the ligation thread, will cause bleeding. 4. Difficulty in defecation: If the mixed hemorrhoid is not completely cured after the mixed hemorrhoid surgery, scar contracture will be formed around the anus, resulting in difficulty in defecation. After mixed hemorrhoid surgery, patients should pay attention to the anal opening hygiene, wash the anal opening in a timely manner after the stool, you can practice lifting the anus, remember to follow up on time after the operation, the time of defecation should not be too long, so as not to affect the postoperative recovery.
