Surgery for 0.8cm intestinal polyps usually takes 30 minutes to 60 minutes, with anesthesia taking about 10 minutes and surgery taking about 30 minutes. Intestinal polyps are a common benign lesion in clinical practice, but the possibility of malignant changes cannot be ruled out. If intestinal polyps are found, they need to be surgically removed in time; first, anesthesia is needed, and the anesthesia time is usually about 10 minutes, and then the surgical treatment is carried out. First, the electronic colonoscope is inserted into the intestines, and then a loop device is used to remove the polyp; if the polyp is wider at the base, it can be considered to be removed with an electrosurgical knife, and the whole operation time is usually about 30 minutes. The polyp tissue cut off during the surgery routinely needs to be pathologically examined to exclude malignant changes. If the pathological examination determines that there is malignancy, further anti-tumor treatment, such as radiotherapy, chemotherapy, etc., is also needed. There is no special drug that can cure intestinal polyps, and the effect will be better through surgical treatment; if abnormal symptoms occur after surgery, patients need to communicate with their doctors in time and go to the hospital for review if necessary.
