Ten-kHz Spinal Cord Stimulation vs Radiofrequency Ablation of Splanchnic Nerves: A Single-Site Retrospective Comparison of 12-Month Outcomes

A prospective study on 10-kHz spinal cord stimulation (SCS) for various causes of chronic abdominal pain (CAP) showed robust improvements in subjects' pain and function. Radiofrequency ablation of splanchnic nerves (snRFA) has been used in advanced pain management treatment algorithms for CAP. This analysis was designed to provide what we believe is the first comparison of the efficacy of these two therapies. Propensity-score matched analysis (PMA) was performed to compare pain relief and decrease in medication usage in snRFA and SCS for treating refractory CAP.
