If you have blood in your stool 11 days after intestinal polyp surgery, you should first clarify whether it is bleeding from the trauma after polyp surgery or bleeding from internal hemorrhoids at the anal opening. If the amount of bleeding is relatively small, no special treatment is needed and the bleeding can usually be stopped by itself; if the amount of bleeding is very large and increasing day by day, you need to go to the hospital in time and perform hemostatic treatment under colonoscopy. If the bleeding of internal hemorrhoids is the main symptom of posterior dripping blood, the first thing to do is to take conservative treatment, using taining suppositories to plug the anus, external use of Ma Yinglong hemorrhoid cream, together with oral treatment such as Sophora Diyu pill.
