Enhanced recovery after surgery for adolescent idiopathic scoliosis: a revised systematic review and meta‑analysis.

PURPOSE: Adolescent idiopathic scoliosis surgery (AIS) is often associated with high costs and significant recovery challenges. Enhanced recovery after surgery (ERAS) protocols aim to improve outcomes, reducing hospital stays and complications compared to traditional (TD) pathways. This study evaluates the impact of ERAS protocols on AIS treatment.

METHODS

Following PRISMA guidelines, a systematic review identified 30 studies (n = 15,954 patients). Search terms included "ERAS," "adolescent idiopathic scoliosis," and "posterior spinal fusion." Outcomes assessed included surgical metrics, recovery milestones, complications, and pain. A meta-analysis was performed, and the risk of bias was evaluated using the MINORS score.

RESULTS

ERAS patients (n = 5582) had shorter surgical durations (- 23 min, p = 0.08) and reduced blood loss (- 126 mL, p = 0.033) compared to TD patients (n = 7916). Recovery milestones improved, including earlier ambulation (- 37.4 h, p < 0.0001), patient-controlled analgesia discontinuation (- 1.1 days, p < 0.0001), catheter removal (- 0.75 days, p < 0.001), and shorter hospital stays (- 1.7 days, p < 0.0001). Complications were lower in the ERAS group (4% vs. 8%, p = 0.0074), while wound-related complications and 30-day readmission rates were comparable. Pain scores were significantly reduced from surgery day to postoperative day 2 (p < 0.0181).

CONCLUSION

ERAS protocols improve recovery and reduce complications in AIS surgery, with shorter hospital stays and enhanced patient outcomes. These findings support broader implementation and further randomized trials to evaluate long-term benefits and patient satisfaction.
