Postoperative complications and long-term outcomes in Currarino syndrome

Purpose This study aimed to present ten cases of Currarino syndrome, study their postoperative complications and prognosis, and analyze whether patient background and clinical factors influenced outcomes. Methods Ten patients with Currarino syndrome who were followed up at our institution between 2004 and 2020 were enrolled. Patient records were retrospectively reviewed for clinical details, postoperative complications, and long-term outcomes. Results The incidence of early postoperative complications was 80%, most of which were transient dysuria. The dysuria significantly developed in the higher normal sacral vertebra ( p = 0.024) and the complete type of Currarino syndrome ( p = 0.033). Later, intractable constipation requiring rectal irrigation and intractable dysuria requiring clean intermittent catheterization occurred in 40% and 30% of the patients, respectively. There was a tendency for tethered cord syndrome ( p = 0.076), and the height of the normal sacral vertebra ( p = 0.071) was related to intractable constipation. The height of the normal sacral vertebra ( p = 0.05) and the tumor size on the image ( p = 0.012) were significantly higher and larger, respectively, in the group with intractable dysuria than in the group without intractable dysuria. Conclusion Postoperative complications, especially early ones, occur at a high rate. Long-term intractable constipation and dysuria may be influenced by the degree of sacral dysplasia.
