The surgical risk of adrenal tumors is related to the tumor condition and the patient’s age as follows: 1. Tumor type: the surgical risk of adrenal cortisol tumor and adrenal protoalgia is relatively low; adrenal pheochromocytoma can have symptoms of high blood pressure, high metabolism, and high blood glucose, etc., and if the preoperative preparation is not sufficient, there will be intense high blood pressure before surgical resection, and intense low blood pressure after surgical resection, so the The surgical risk of pheochromocytoma is very high; 2. Age: the older the patient is, the higher the surgical risk is relatively; 3. Tumor size: the size of the adrenal tumor also determines the surgical risk, the larger the tumor is, and the more obvious the invaded local organs are, the higher the surgical risk is. Because the adrenal gland is a deep organ, and there was a lack of knowledge about perioperative preparation before, the risk of adrenal tumors, especially adrenal pheochromocytoma, is higher. In recent decades, the surgical risk of adrenal tumors has been significantly reduced due to the emphasis on perioperative evaluation and management by both surgeons and anesthesiologists. The magnifying effect of laparoscopy and the use of intracardiac devices have significantly reduced the risk of bleeding in adrenal tumor resection, resulting in a high surgical success rate. As a more mature technique, laparoscopic and especially posterior laparoscopic adrenal tumor resection has become a more common surgical procedure.
