ABSTRACT
BACKGROUND:
There has been some controversy regarding the efficacy of sacral nerve stimulation (SNS) for the treatment of chronic constipation, due to less positive outcomes and concerns about cost-effectiveness in the long term. The aim of the present study was to evaluate the long-term outcomes of SNS in patients with chronic constipation.METHODS:
A retrospective study was conducted on patients who had SNS for chronic constipation in 2008-2017 at our institution. Clinical factors, profile of constipation, physiology studies, and patient satisfaction with SNS therapy were investigated during a follow-up period up to 10 years after the implantation.RESULTS:
Twenty-nine patients [86% female, median age 49 years (range 17-86)] were tested for SNS, and 24 received implants after a positive test phase [median 47 days (range 21-56 days)]. There were 27 bilateral and 2 unilateral implants, in S3 or S4 depending on best response. Mean follow-up was 59 months. Efficacy was considered as a score > 5 (on a scale of 1-10) in general symptom improvement. Nine (37.9%) implanted patients had a satisfaction score > 5. In 6 cases (25%), patient satisfaction was higher than 9. Due to the small sample size, there were no statistically significant variables considered as predictors of response.CONCLUSIONS:
Our results agree with current studies which describe around a 30% response of SNS for refractory constipation. However, there is a small group of patients highly satisfied with SNS therapy. More studies are needed to better understand this profile and optimize outcomes.Palabras clave
