Digestive Health (2)
Investigators from the Julius Center for Health Sciences and Primary Care at the University Medical Center Utrecht in the Netherlands, reviewed the research literature on efficacy of psychological interventions for the treatment of irritable bowel syndrome.
MEDLINE, EMBASE, PsychInfo, CINAHL, Web of Science, The Cochrane Library and Google Scholar identified 25 randomized trials comparing single psychological interventions with either usual care or placebo interventions in patients over 16 years of age, between the years 1966-2008.
This study assessed the efficacy of hypnotherapy in treating functional dyspepsia (FD). A total of 126 patients were randomized to either a hypnotherapy condition, a supportive therapy plus placebo medication condition, or a medical treatment condition, for a total of 16 weeks of treatment.
The percentage of change in symptoms from baseline was assessed after the 16-week treatment phase (short-term) and again after 56 weeks (long-term), with the 26 hypnotherapy, 24 supportive therapy, and 29 medical treatment patients who completed all phases of the study. In addition, quality of life was also measured as a secondary outcome.
