ObjectiveThe authors reviewed the treatment of adult patients with congenital intraspinal lipomas with total/near-total resection and discussed their preoperative characteristics, prognostic factors, and surgical outcomes.MethodsMedical records of 122 adult patients with congenital lumbosacral lipomas undergoing total/near-total resection were systematically analyzed. The cohort was subdivided into 3 groups depending on symptom onset age: group 1 (≤5 years, n = 40), group 2 (>5 years but <18 years, n = 33), and group 3 (>18 years, n = 49). Preoperative and postoperative neurologic status were compared between groups and analyzed as a whole.ResultsThe most common symptom was bladder dysfunction (82.0%), followed by constipation (76.2%). At the 3-month follow-up, improvement was noted in most patients presenting with pain (87.2%) and neuropathic ulcers (70.0%). Overall, neurologic status was improved in 73.0% of patients and stabilized in 19.7% of patients. A binary logistic regression model identified shorter preoperative duration (P = 0.013) and preoperative pain (P = 0.005) as independent predictors of postoperative improvement. Neurosurgical complications developed in 16 patients, and wound complications occurred in 2 patients. Two of 3 patients who had recurred symptoms underwent repeated detethering surgery during long-term follow-up.ConclusionsDespite longer preoperative duration than the pediatric population, adult patients with lumbosacral lipomas can still benefit from total/near-total resection especially regarding pain and foot ulcers, with low surgery-related morbidity. The long-term advantage of resecting additional lipoma in adults remains a point of discussion.Copyright © 2018 Elsevier Inc. All rights reserved.
