Cohort study reveals improved recovery and shorter hospital stays with diabetes-specific ERAS nutrition in lumbar spinal stenosis and diabetes, highlighting the value of tailored perioperative care.
OBJECTIVE: To evaluate early postoperative nutritional management with a diabetes-specific enhanced recovery after surgery (DS-ERAS) pathway in patients with lumbar spinal stenosis (LSS) and type 2 diabetes mellitus (T2DM). METHODS: This retrospective cohort study compared a DS-ERAS nutritional pathway with conventional perioperative care in LSS patients with T2DM. Outcomes included postoperative recovery, nutritional status, glycemic control, inflammation, complications, and hospital stay. Effect size metrics (relative risk reduction [RRR], absolute risk difference [ARD], number needed to treat [NNT]), subgroup analyses, and multivariable linear regression were performed. RESULTS: for interaction > 0.05). Multivariable regression show that DS-ERAS was associated with a mean reduction in hospital stay of 1.57 days. CONCLUSION: Early postoperative nutritional management within the DS-ERAS pathway was associated with improved perioperative recovery in LSS patients with T2DM, with favorable nutritional , metabolic, inflammatory, and clinical outcomes.
