Sacral cysts are actually cystic changes that grow in the spine and are not tumorigenic in nature, nor do they need to be distinguished as benign or malignant, and they grow slowly and in some cases do not even produce any obvious clinical symptoms. Therefore, it is important to be cautious about its treatment. Generally speaking, if patients have no obvious clinical symptoms or only mild clinical symptoms, they can be relieved by oral medication or can be temporarily observed first. If, for example, a relevant review is performed every three months, and if, indeed, after these three months, there is a significant growth trend as well as significant clinical symptoms, then treatment by means of surgical procedures is required. For example, if there is severe pain in the lower back and legs, intermittent claudication, failure to improve with medication, serious impact on daily life and work, loss of muscle strength and sensation in the lower extremities, pain in the perineum, urinary and fecal disorders, etc., surgical treatment is required. The general procedure of surgery is to trim and shape the cyst under a microscope, remove the cyst wall, protect the nerve roots, and then find the cerebrospinal fluid fistula and close it with sutures or reshape it. After surgery, the patient is usually placed in a prone position with the head low and hips high, and then the wound is pressurized with a sandbag, and he or she is usually able to move off the floor after a week.
