LST of the ascending colon is an abbreviation for lateral developmental tumor arising in the ascending colon area. If you are eligible for surgery, it is recommended that you cooperate with your doctor as soon as possible for surgical treatment. LST of the ascending colon has a certain malignant potential, and with the growth of the disease, it will have a great impact on the patient’s health, so it needs to be treated promptly and actively. Patients with LST of the ascending colon can be treated with endoscopic minimally invasive treatments such as endoscopic mucosal dissection and endoscopic mucosal resection under the guidance of the doctor when the lesions are relatively mild; and surgical resection can be performed when the lesions are severe. During the treatment period, patients need to try to avoid eating peppers, ginger and other foods that can cause strong irritation to the digestive tract, otherwise it may lead to inflammation in the body, affecting the recovery of the wound after surgery.
