Minimally invasive mediastinal surgery, i.e., minimally invasive surgery used to treat mediastinal tumors, and how long it takes to follow up after minimally invasive mediastinal surgery is related to the type of pathology of the mediastinal tumors being treated. Some are a week or two, some are six months or even a year. In the case of benign mediastinal tumors, a review is needed one to two weeks after surgery. The review is to see how the surgical incision is healing, so that any infection, bruising, or poor healing can be addressed. If everything is normal and the patient recovers well after the follow-up, regular follow-ups may not be needed later. However, for mediastinal tumors that are benign but also have malignant behavior, they are prone to recurrence after surgery, so it is necessary to have regular checkups, from half a year to one year, and if there is no recurrence, the interval between checkups can be prolonged under the doctor’s advice. In case of malignant mediastinal tumors, it is usually necessary to review every six months to find out whether there is any recurrence. The specific frequency and duration of review vary from person to person, and patients should be advised by their doctors for review and follow-up treatment.
