Adrenal adenoma surgery may have complications such as retroperitoneal hematoma, peritoneal injury, central adrenal vein injury, etc. However, the incidence of such complications can be significantly reduced after systematic preoperative preparation and monitoring. 1. Retroperitoneal hematoma: this kind of injury is mainly due to the tearing of small blood vessels when separating them during the operation, which is manifested as the swelling and pain of the affected side of the waist and discomfort after the operation, which can be detected through ultrasound and other examinations, and most of them can be cured after conservative treatment. 2. Peritoneal injury: mainly due to the separation operation may damage the peritoneum, peritoneal injury generally do not need special treatment, unless the damage to intra-abdominal organs. 3. Injury to the central adrenal vein: bilateral adrenal vessels are rich and thin-walled, intraoperative injury to this vein can lead to large bleeding, but such cases are usually rare, and after the occurrence of hemostasis is usually carried out immediately, which usually does not cause serious effects. In addition, other surgical risks such as adrenal crisis may occur. To summarize, it is recommended to go to the hospital in time when adrenal adenoma occurs; the probability of the above complications is relatively low, and before the surgery, there will be a complete solution for possible accidents, so do not resist the surgery because of fear of the possible complications of the surgery.
