Mixed hemorrhoid patients may experience perianal infection, anal stenosis, anal incontinence and other sequelae after recovery from surgery. 1. Perianal infection: the most common complication after hemorrhoid surgery is perianal infection, due to the anus is a contaminated organ, there are more germs in the stool, and the patient’s postoperative defecation residue will contaminate the surgical incision, which will lead to perianal infection. 2. Anal stenosis: for mixed hemorrhoids is more serious, or accompanied by traumatic infection of patients, may lead to poor healing of the incision, triggered by adhesion and other conditions, resulting in the emergence of anal stenosis and other sequelae. 3. anal incontinence: because the anus is dependent on the anal sphincter for control, hemorrhoid surgery may damage the anal sphincter, causing anal incontinence, in addition, the nerves around the anus are very rich, more sensitive to the stimulation of pain, so postoperative pain stimulation may also trigger anal incontinence. It is recommended to do a good job of postoperative care after mixed hemorrhoid surgery, to keep the perianal area clean, dry, if there are symptoms of discomfort, should be timely consultation and treatment, to avoid affecting the normal recovery after surgery.
