The treatment of blood in the stool after intestinal polyp surgery requires a clear understanding of the cause of the blood in the stool and whether there is any delayed bleeding after intestinal polyp surgery. If delayed bleeding occurs, urgent colonoscopy is needed, and then colonoscopic treatment is given to stop the bleeding. If this delayed bleeding persists repeatedly without relief, it may lead to gastrointestinal hemorrhage. Because intestinal polyps are often removed, they can easily lead to localized bleeding or if they are incompletely closed with titanium clips. This may lead to localized rupture and bleeding of small vessels, especially small arteries. The chronic blood loss from such bleeding can be very large and the amount of bleeding can sometimes be quite violent. If the amount of bleeding is relatively small and there is only localized abrasion on colonoscopy, this type of blood in the stool can be considered for symptomatic treatment with oral Yunnan Baiyao and continued clinical observation. For other possible bleeding conditions, such as hemorrhoids, symptomatic treatment with compound carnosic acid can be considered.
