Formation of syringomyelia Syringomyelia is a common congenital developmental abnormality in which fluid from the abdominal cavity protrudes into the scrotum via the unclosed sphincter when there is a pressure difference due to the unclosed peritoneal sphincter. Depending on the location of the sphincter closure, it can be divided into types such as testicular syringomyelia, spermatic syringomyelia, and traffic syringomyelia. Clinical symptoms of syringomyelia A cystic mass in the scrotum or inguinal region with smooth surface, cystic sensation, no pressure pain, positive transillumination test, testes and epididymis are not palpable. In male children, if the local tension of syringomyelia is high, it may affect the blood supply to the ipsilateral testis and affect the testicular development. Treatment of syringomyelia Follow-up studies have found that syringomyelia may heal spontaneously in infants up to 2 years of age, but the chance of healing decreases after 2 years of age. Therefore, children with syringomyelia > 2 years of age with a clear diagnosis should be surgically corrected. If the local tension of syringomyelia is high, it may affect the blood supply to the testis and affect the development of the testis, so surgery is not restricted by age. Postoperative complications of syringomyelia 1. intraoperative and postoperative bleeding; postoperative infection and fever; 2. postoperative groin recurrence (ipsilateral or contralateral); 3. postoperative scrotal swelling. Which children should have syringomyelia surgery According to the basic medical opinion, in principle, as long as the diagnosis is clear, children with syringomyelia >2 years old are feasible for syringomyelia high ligation + syringomyelia opening and drainage. If a child with syringomyelia is ≤2 years old but has high local tension, surgery can still be considered. Points for postoperative care of syringomyelia 1. Position and activity: postoperative lying down with the pillow removed for 6 hours. Because of the increase of respiratory secretions and muscle relaxation under anesthesia, it is easy to cause vomiting and misaspiration. If there is vomiting, please remove the vomit in time, change clean clothes and pants, and need to pay attention to the color of the child’s mouth and lips, if there is cyanosis, phlegm in the throat and difficulty in breathing, the doctor or nurse needs to be notified immediately. After the operation, the nurse will routinely place your child on cardiac monitoring and oxygen for 6 hours. Please be careful not to let your child grasp the tube and get out of bed after 6 hours. 2. Wound care: If there is a small amount of blood oozing from the wound, it is normal and no treatment is needed. If the blood oozing is bright red and the area is wetting the whole layer of gauze, please inform the doctor in time; usually the outer layer of the wound is put on a transparent waterproof dressing, pay attention to prevent urine from wetting the wound, keep the bed clean and dry, and change the diaper in time. The wound will heal in about 1 week. 3, diet: no water and food before anesthesia awake, 2 hours after surgery can enter a little plain water water, if there is no nausea, vomiting and other discomfort can be light and easy to digest food, such as thin rice, milk, noodles, cakes, etc., the first day after surgery to resume normal diet.
