Long-term effects of hypnotherapy in patients with refractory irritable bowel syndrome.

OBJECTIVE: Gut-directed hypnotherapy is considered to be an effective treatment in irritable bowel syndrome (IBS) but few studies report the long-term effects. This retrospective study aims to evaluate the long-term perceived efficacy of gut-directed hypnotherapy given outside highly specialized hypnotherapy centers. METHODS: 208 patients, who all had received gut-directed hypnotherapy, were retrospectively evaluated. The Subjective Assessment Questionnaire (SAQ) was used to measure changes in IBS symptoms, and patients were classified as responders and non-responders. Patients were also asked to report changes in health-care seeking, use of drugs for IBS symptoms, use of alternative non-pharmacological treatments, and if they still actively used hypnotherapy. RESULTS: Immediately after hypnotherapy, 103 of 208 patients (49%) were responders and 75 of these (73%) had improved further at the follow-up 2-7 years after hypnotherapy (mean 4 years). A majority of the responders still used hypnotherapy on a regular basis at follow-up (73%), and the responders reported a greater reduction in health-care seeking than non-responders. A total of 87% of all patients reported that they considered gut-directed hypnotherapy to be worthwhile, and this differed between responders and non-responders (100% vs. 74%; p < 0.0001). CONCLUSION: This long-term follow-up study indicates that gut-directed hypnotherapy in refractory IBS is an effective treatment option with long-lasting effects, also when given outside highly specialized hypnotherapy centers. Apart from the clinical benefits, the reduction in health-care utilization has the potential to reduce the health-care costs.

Effects of gut-directed hypnotherapy on IBS in different clinical settings-results from two randomized, controlled trials.

OBJECTIVES: Gut-directed hypnotherapy has been found to be effective in irritable bowel syndrome (IBS). However, randomized, controlled studies are rare and few have been performed outside highly specialized research centers. The objective of this study was to study the effect of gut-directed hypnotherapy in IBS in different clinical settings outside the traditional research units. METHODS: The study population included IBS patients refractory to standard management. In study 1, patients were randomized to receive gut-directed hypnotherapy (12 sessions, 1 h/week) in psychology private practices or supportive therapy, whereas patients were randomized to receive gut-directed hypnotherapy in a small county hospital or to serve as waiting list controls in study 2. Gastrointestinal symptom severity and quality of life were evaluated at baseline, at 3 months follow-up and after 1 year. RESULTS: We randomized 138 IBS patients refractory to standard management, 90 in study 1 and 48 in study 2. In both the studies, IBS-related symptoms were improved at 3 months in the gut-directed hypnotherapy groups (P<0.05), but not in the control groups (ns). In study 1, a significantly greater improvement of IBS-related symptom severity could be detected in the gut-directed hypnotherapy group than in the control group (P<0.05), and a trend in the same direction was seen in study 2 (P=0.17). The results seen at 3 months were sustained up to 1 year. CONCLUSIONS: Gut-directed hypnotherapy is an effective treatment alternative for patients with refractory IBS, but the effectiveness is lower when the therapy is given outside the highly specialized research centers.
