Abstract

Background: Irritable bowel syndrome (IBS) is a very common condition worldwide. Treatment options for severe IBS are few. Sacral neuromodulation (SNM) for patients with IBS has been shown to reduce symptoms and improve quality of life in the medium term. This study aimed to evaluate the long-term effectiveness and safety of SNM in diarrhoea-predominant and mixed IBS. Methods: A prospective cohort of patients with IBS treated with SNM were evaluated 1, 3, 5, and 10 years after implantation. The primary end-point was a change in the Gastrointestinal Symptom Rating Scale–Irritable Bowel Syndrome version questionnaire (GSRS-IBS) from baseline to 10-year follow-up (FU). Secondary end-points were change in the GSRS-IBS score from baseline to 5-year FU and change in the Irritable Bowel Syndrome–Impact Scale questionnaire (IBS-IS) from baseline to 5- and 10-year FU. Adverse events following SNM were observed. Results: Of 36 patients treated with SNM, 23 were eligible for 5-year FU and 13 for 10-year FU. The GSRS-IBS score was significantly reduced at both 5-year (p < 0.0001) and 10-year (p = 0.0007) FU. The IBS-IS score was also significantly improved at both 5 years (p < 0.0001) and 10 years (p = 0.0002). Fifty-six adverse events were registered. Five patients were explanted because of adverse events. Conclusion: SNM seems to offer an effective and safe treatment option for highly selected patients with diarrhoea-predominant and mixed IBS. Clinical trial registration: The present study has not been registered. The latest founding study was registered at ClinicalTrials.gov, NCT01948973.
