Can I have a stool that “won’t shut off” after a hemorrhoid surgery? This is an issue of great concern to many hemorrhoid patients. Anal incontinence in the clinical can be divided into 3 types: 1, complete incontinence, that is, the patient is completely unable to control the anal defecation and exhaustion at will, in the abdominal pressure increases or anal relaxation will have secretions or stool on their own leakage. 2, incomplete incontinence, that is, the patient can control the dry stool at will, but can not control the discharge of thin stool and gas. 3, sensory incontinence, this patient’s bowel sensation is dull, so that the stool is out of control. Generally speaking, the standard hemorrhoid surgery done by a specialist will not appear anal incontinence, otherwise it is caused by improper surgery. The reasons for this are: 1. When circumcision of hemorrhoids is done, too much tissue is removed or too deep, damaging the receptors near the anal dentate line and causing reflex sensory impairment of defecation. 2.The nerves in the perineum of the anus were damaged during the surgery. 3.The surgery damaged the angle of the anal canal rectum. 4.Surgery for high anal fistula severed the anorectal ring (consisting of the internal and external sphincter and related ligaments). To prevent anal incontinence caused by hemorrhoid surgery errors, it is highly recommended that hemorrhoid patients must go to a regular hospital anorectal specialist to receive surgical treatment.
