Multidisciplinary management of spinal lipoma.

摘要

Spinal lipomas (congenital lipomyelomeningoceles) can cause significant aesthetic deformity of the lower spine in addition to recognised neurological problems. Surgical management consists of untethering the cord in symptomatic cases, and debulking of the lipomatous component to improve the spinal contour. However, management remains controversial. Between May 1998 and November 2002, 23 cases of lumbosacral spinal lipoma were operated on by neurosurgeons at our hospital. Of these, eight (34%) patients were subsequently referred to plastic surgery for aesthetic revision, which was performed by a combined team of plastic surgeons and neurosurgeons. In addition, three new patients had their primary surgery as a planned procedure performed by the same combined team. The purpose of this paper is to present the method and results of combined plastic surgery and neurosurgery technique in these 11 cases of spinal lipoma. Follow up ranged between 12 months and 4 years (mean 20 months). One patient had wound break down and three patients developed seroma. Two patients had cerebrospinal fluid (CSF) leakage which required re-exploration and prolonged hospitalisation. The aesthetic results were very satisfactory in 10 out of the 11 patients. The frequency of secondary referral for aesthetic revision, together with the incidence of CSF leak, underlines the importance of managing spinal lipomas in a multidisciplinary team involving neurosurgeons and plastic surgeons. This series demonstrates that aesthetic results are encouraging but decreasing the CSF leakage rate remains a challenge. Further follow up will determine the role of early combined surgery in the management of spinal lipoma.
