If there is often residual stool at the anal opening during non-defecation time, it is considered that there may be fecal outflow due to excessive local relaxation of the anus, or the internal hemorrhoids are large and repeatedly prolapse and bring out a small part of the residual stool in the anal canal, which requires further anal finger diagnosis and anoscopy to clarify the cause. If it is due to too loose anus, you can choose anal tightening and instruct the patient to perform daily training of anal lifting exercises. If the internal hemorrhoid is repeatedly prolapsing and the anal opening is slowly enlarging, or if the size of the hemorrhoid is increasing and causing localized fecal residue, surgery is recommended to remove the localized internal or external hemorrhoid. If the stool is too thin or accompanied by diarrhea, you can choose to take oral montmorillonite and medication for inflammatory bowel disease for comprehensive treatment.
