This prospective observational cohort study tracked 105 stenosis patients for at least eight years following surgical or non-operative treatment. Although the measured outcomes favored surgery for four years, the benefits over nonoperative therapy disappeared by ten years. This study provides the best long-term clinical results of surgery for stenosis.
