The main purposes of postoperative review of pituitary tumor are as follows: 1. Whether the tumor recurs or not: in the vast majority of patients, the tumor will not recur after complete resection, but there are still some individual cases of tumor regrowth, and the site of growth is usually in the original tumor site. Generally, 1-2 times of review in the first year after surgery, if there is no clinical symptom and imaging abnormality, the number of review will be gradually reduced. 2. Whether the tumor grows again: Strictly speaking, the definition of tumor recurrence and tumor regrowth is different, the former refers to complete resection of the tumor by surgery, and then the same kind of tumor grows inside the skull; the latter refers to partial resection of the tumor by surgery, but a part of the tumor remains inside the skull, and then the residual tumor grows again in the future. In this case, the number of review is more than the former, because the condition is different, the number and interval of review should be determined according to the specific situation, and the occurrence of clinical symptoms or aggravation of the original symptoms should be reviewed in time. After the review of timely detection of problems, give timely treatment. Understanding the patient’s physical condition: after the surgery of some brain tumors, there are many changes of human body functions and organs, such as high blood sugar, high blood pressure, endocrine dysfunction, infertility, cardiac failure, bone fracture of the patients with pituitary tumors before the surgery. Do they still need to be given hypoglycemic and hypotensive treatments? Whether the infertility problem is related to other diseases, whether endocrine disorders need hormone replacement therapy and a series of other problems need to be dealt with after the review. Some problems can be solved easily, such as infertility, which can be treated with a few medications, but some patients do not pay attention to the review, which delays the chance of treatment. In conclusion, through the review, it can further determine the effect of surgery, timely detection of problems and timely treatment, which is an important guidance for the future health of pituitary tumor patients.
