Patients with blood in stool usually do not use corkscrew, usually need to do further colonoscopy to clarify the diagnosis, after the diagnosis is clear and then symptomatic treatment, if necessary, need surgical treatment. Kesselol is also known as glycerin, the main purpose is to lubricate the stool, usually seen in constipated patients, because the stool is too dry, hard to discharge may lead to dry cracks, or because the feces is too dry, the patient intestinal peristalsis is too weak, resulting in feces can not be discharged, which triggered secretory intestinal obstruction. Therefore, patients generally use corkscrew to soften the stool, so that the dry and hard stool can be easily discharged. Blood in the stool is mainly seen in hemorrhoids, intestinal tumors or polyps, the use of corkscrew can not achieve the therapeutic purpose, so the blood in the stool usually need to perform a colonoscopy in order to clarify the diagnosis. Hemorrhoids are often treated conservatively, colon polyps or tumors need timely surgical treatment, and sent to the pathological examination, to exclude the possibility of malignant changes. When malignant lesions are confirmed, radical treatment of intestinal cancer needs to be added and combined with postoperative comprehensive treatment.
