Hypnosis for irritable bowel syndrome: the empirical evidence of therapeutic effects.
ABSTRACT Irritable bowel syndrome (IBS) is a complex and prevalent functional gastrointestinal disorder that is treated with limited effectiveness by standard medical care. Hypnosis treatment is, along with cognitive-behavioral therapy, the psychological therapy best researched as an intervention for IBS. Eleven studies, including 5 controlled studies, have assessed the therapeutic effects of hypnosis for IBS. Although this literature has significant limitations, such as small sample sizes and lack of parallel comparisons with other treatments, this body of research consistently shows hypnosis to have a substantial therapeutic impact on IBS, even for patients unresponsive to standard medical interventions. The median response rate to hypnosis treatment is 87%, bowel symptoms can generally be expected to improve by about half, psychological symptoms and life functioning improve after treatment, and therapeutic gains are well maintained for most patients for years after the end of treatment.

ABSTRACT: Résumé Objectif Nous souhaitons faire une brève revue des différentes théories psychologiques du stress, afin de mieux comprendre quelle place ce concept prend dans la question des douleurs viscérales, notamment abdominales. Méthode Synthèse critique des articles significatifs sur le stress et les douleurs viscérales tant chez l’enfant que chez l’adulte. Résultats Il est démontré une grande influence des événements pourvoyeurs de stress dans les douleurs viscérales. Pour autant, le lien de causalité ne peut être démontré. Conclusion La clinique des douleurs viscérales est complexe. De ce fait, elle s’est ouverte vers des voies thérapeutiques complémentaires qui semblent apporter satisfaction dans nombre de situations.Douleur et Analgésie 12/2010; 23(4):226-231.

ABSTRACT: Psychotherapy is not routinely recommended for in ulcerative colitis (UC). Gut-directed hypnotherapy (HYP) has been linked to improved function in the gastrointestinal tract and may operate through immune-mediated pathways in chronic diseases. To determine the feasibility and acceptability of HYP and estimate the impact of HYP on clinical remission status over a 1-year period in patients with an historical flare rate of 1.3 times per year. A total of 54 patients were randomised at a single site to seven sessions of gut-directed HYP (n = 26) or attention control (CON; n = 29) and followed for 1 year. The primary outcome was the proportion of participants in each condition that had remained clinically asymptomatic (clinical remission) through 52 weeks post treatment. One-way analysis of variance comparing HYP and CON subjects on number of days to clinical relapse favoured the HYP condition [F = 4.8 (1, 48), P = 0.03] by 78 days. Chi-squared analysis comparing the groups on proportion maintaining remission at 1 year was also significant [χ(2) (1) = 3.9, P = 0.04], with 68% of HYP and 40% of CON patients maintaining remission for 1 year. There were no significant differences between groups over time in quality of life, medication adherence, perceived stress or psychological factors. This is the first prospective study that has demonstrated a significant effect of a psychological intervention on prolonging clinical remission in patients with quiescent ulcerative colitis (Clinical Trial # NCT00798642).Alimentary Pharmacology & Therapeutics 08/2013; DOI:10.1111/apt.12449 · 4.55 Impact Factor

ABSTRACT: This study explores whether self-reported depth of hypnosis and hypnotic suggestibility are associated with individual differences in neuroanatomy and/or levels of functional connectivity. Twenty-nine people varying in suggestibility were recruited and underwent structural, and after a hypnotic induction, functional magnetic resonance imaging at rest. We used voxel-based morphometry to assess the correlation of grey matter (GM) and white matter (WM) against the independent variables: depth of hypnosis, level of relaxation and hypnotic suggestibility. Functional networks identified with independent components analysis were regressed with the independent variables. Hypnotic depth ratings were positively correlated with GM volume in the frontal cortex and the anterior cingulate cortex (ACC). Hypnotic suggestibility was positively correlated with GM volume in the left temporal-occipital cortex. Relaxation ratings did not correlate significantly with GM volume and none of the independent variables correlated with regional WM volume measures. Self-reported deeper levels of hypnosis were associated with less connectivity within the anterior default mode network. Taken together, the results suggest that the greater GM volume in the medial frontal cortex and ACC, and lower connectivity in the DMN during hypnosis facilitate experiences of greater hypnotic depth. The patterns of results suggest that hypnotic depth and hypnotic suggestibility should not be considered synonyms. Copyright © 2014 Elsevier Ireland Ltd.
