Minimally invasive surgery for syringomyelia requires a routine preoperative examination followed by shaving of the perineum. On the day of surgery, the patient is admitted to the operating room by the operating room nurse. Anesthesia is administered by an anesthesiologist first. After the anesthesia takes effect, the doctor disinfects the patient, lays a sterile surgical pad sheet on the patient’s body, and then pokes a hole in the patient’s scrotal skin with a specialized device to access the sphincter cavity. Then the surgical equipment is placed and saline or electrodes are flushed into the sheath cavity to provide adequate visualization and surgical space. The surgeon removes the patient’s testicular sheath with surgical instruments and extracts the fluid from the body. After these operations are done, the surgical instruments are withdrawn, and then a drainage strip is left in place in the operative area and the wound is simply sutured. The patient is sent to the anesthesia observation room and can be sent back to the ward after thirty minutes of observation.
