If there is no occult blood in the stool in a short period of time after intestinal polyp resection, it may be that the amount of bleeding during the operation itself is very small, or the specimen collection did not pick up the place where there is blood, if it is a long period of time after the interval of rechecking, it has already healed, which is a normal phenomenon. 1. Low intraoperative bleeding: at present, intestinal polyps are generally treated by minimally invasive surgery under enteroscopy, with low bleeding during the resection process. After the polyp is removed, the surgeon will generally observe whether there is bleeding or not, and if there is bleeding, the bleeding will be completely stopped. If there is very little bleeding during the surgery itself, there may be no occult blood in the stool after the surgery. 2. The specimen is not collected: when the stool examination is conducted, not all of the stool is sent for examination, but a part of it is randomly selected and sent for examination. Due to the randomness of the sampling, it is possible that the stool with blood is not collected, resulting in the absence of occult blood in the stool. 3. Already healed: If the incision is reviewed after a long period of time, the incision has already healed and the absence of occult blood in the stool is a normal phenomenon. The absence of occult blood in the stool generally means good recovery after surgery, and there is no need to be overly nervous, you should follow the doctor’s advice for regular checkups, and consult the doctor in time when discomfort occurs, so as to avoid delaying the condition.
