It is necessary to register for a follow-up consultation. After the surgery, you should come to the hospital for a follow-up consultation strictly according to the timing of the follow-up consultation, such as 3 months, 6 months and 1 year after the surgery. It is better to register for the number of the attending doctor who has seen the patient before, because he knows your condition better and is more familiar with it. The first thing we need to do is to understand the general condition of the patient’s recovery, whether there is any abdominal pain, and to observe the healing of the incision, whether there is redness, inflammation, and reaction to the nodes. At the same time, according to the different conditions, different laboratory tests and ultrasound examinations will be issued, and if necessary, abdominal CT or gastroscopy or colonoscopy will be performed for follow-up. If certain lesions are found, if they are diagnosed early, they need to be treated early.
