BackgroundChronic abdominal pain is a debilitating condition known for its multifactorial nature. Outcomes with spinal cord stimulation (SCS) for abdominal pain syndromes are noticeably absent in the literature. To date, there have been no published reports of novel waveforms of SCS for management of chronic abdominal pain. We assessed the efficacy and durability of BurstDR SCS in reducing abdominal pain and analgesic consumption.Case DescriptionWe performed a retrospective review of medical records from 3 patients with different etiologies of abdominal pain (postherniorrhaphy pain syndrome, Crohn disease, abdominal neuropathy). All patients underwent thoracic laminectomy for BurstDR SCS paddle lead and pulse generator placement after a successful trial stimulation period. Data were collected with a telephone survey after a minimum duration of >24 months following implantation. Pain scores were measured using a numeric rating scale. Two of 3 patients were entirely pain-free and reported Patient Global Impression of Change scores of 7 after a minimum follow-up of >24 months. While the third patient continued to have chronic as well as episodic abdominal pain, he was able to discontinue all narcotic pain medications and experienced a 33% decrease in frequency and 60% decrease in severity of monthly pain exacerbations. He reported satisfaction and a Patient Global Impression of Change of 6.ConclusionsBurstDR SCS is a new programming modality, and long-term follow-up is necessary to determine its durability. Despite varying etiologies of abdominal pain, this series suggests BurstDR SCS sustained for >2 years might be effective as a treatment for abdominal pain syndromes. Future studies of SCS would benefit from standardized abdominal pain scores and high-powered studies using global patient registries.Copyright © 2020 Elsevier Inc. All rights reserved.
