Trimming of granulation tissue after anal fissure surgery does not require hospitalization and can be done on an outpatient basis. Trimming of granulation tissue after surgery is a very minor surgical procedure that can be performed on an outpatient basis, but patients need to pay attention to keeping their stools clear, because the nature of stools is related to the healing of anal fissure wounds, and if the stools are relatively hard, it will affect the healing of wounds in anal fissure patients. In most cases, patients with anal fissure do not need to trim the granulation tissue after surgery, unless the proliferation of granulation tissue in the anal fissure wound is too obvious, affecting the normal healing of the wound, and then only consider trimming the granulation tissue in the anal fissure wound. For anal fissure patients, usually need to keep the bowel movement, eat more fiber-rich fresh vegetables, fruits, avoid greasy spicy stimulating food, drink more water, usually if there is discomfort, go to the hospital in a timely manner, as soon as possible to give treatment, do not be careless, so as not to delay treatment.
