After 20 days of minimally invasive rectal surgery, the discharge of mucous membrane-like things is a normal phenomenon, belonging to the local secretion, regular cleaning and dietary regulation can be. Minimally invasive rectal surgery is usually used to remove internal hemorrhoids, polyps or early cancerous tissues, and does not cause serious damage to the rectum and its surrounding digestive system during the surgery, so postoperative recovery is faster and less painful. After the surgery, due to the stimulation of the surgical wound, a small amount of local secretion may be produced, which is mucus-like and is a normal physiological reaction. If there is local mucus secretion after minimally invasive rectal surgery, regular surgical wound cleansing and perianal cleansing can effectively remove the secretion and keep the surgical wound healthy and dry. At the same time, the diet should be light and nutritious, try to avoid contact with spicy and stimulating food, can also effectively relieve the phenomenon of more secretion, to avoid the emergence of postoperative inflammation. There is no need to be overly nervous when mucus-like secretion or other normal physiological phenomena occur after minimally invasive rectal surgery, which can be effectively relieved by regular cleaning, and it is also recommended to have a regular review after the surgery.
