Whether or not to hospitalize an intestinal polyp at 1.2 cm depends on the severity of the condition and the patient’s specific situation, and cannot be generalized. Patients who are in relatively good physical condition and have no underlying diseases can generally choose to have their polyps removed endoscopically, as polyps of 1.2 centimeters are not large. This type of surgery is less invasive, usually without complications such as perforation and bleeding, and recovery is quick. Therefore, hospitalization is usually not necessary, and polypectomy can usually be completed on an outpatient basis with observation of the condition. If the patient’s health is relatively poor, and accompanied by anemia, hypertension, diabetes and a series of underlying diseases, this situation, even if the intestinal polyp 1.2cm is not large, usually need to be hospitalized for surgical treatment, so as to avoid bleeding at the treatment site, infections and other related lesions. In the case of intestinal polyps 1.2 cm, it is necessary to actively listen to the advice and arrangement of professional doctors for treatment. Follow the doctor’s instructions.
