Intestinal polyps may bleed in the stool after removal, the reason may be blood seepage from the incision, loose titanium clips or direct exposure of blood vessels, as follows: a. Blood seepage from the incision: If it is a small amount of bleeding, a small amount of blood is discharged during the bowel movement, usually the blood seepage from the incision after the polyps, this is within the normal range. Because the intestinal polyps after removal, in the polyps intestinal wall will leave an incision, defecation and intestinal peristalsis will stimulate a small amount of bleeding from the incision, the amount of bleeding is not large, generally no problem. Second, loose titanium clip or direct exposure of blood vessels: If the bleeding volume is relatively large, and the bleeding volume reaches 200-300mL or even more, it is usually due to the loosening of the titanium clip that clamps the polyp incision after surgery, or the direct exposure of blood vessels in the incision, further stimulated by intestinal peristalsis and defecation, resulting in increased bleeding, which needs to be dealt with as soon as possible to stop bleeding under colonoscopy.
