Caudal anesthesia for anorectal surgery in a rare case of syringomyelia in a day-surgery clinic

Syringomyelia is a rare neurological disease that is characterized by a degenerated and cystic spinal cord. General or spinal anesthesia can cause development of or exacerbation of syringes in these patients, and the optimal anesthetic method for use in patients with syringomyelia remains unclear. Here, we present the case of a patient with syringomyelia in whom caudal anesthesia was used for anorectal surgery in a day-surgery clinic. Surgery was concluded successfully, without any neurological complications associated with syringomyelia. This case demonstrates that caudal anesthesia may be an option for non-obstetric surgery in patients with syringomyelia, if it is performed by experienced medical staff.
