The Impact of the Hypnosis on the Loss of Weight at Patients in Failure of Bariatric Surgery (BARIATHYPNOSE)

A Prospective Randomized Clinical Trial, in Open-label, Multicenter, Estimating the Impact of the Hypnosis on the Loss of Weight at Patients in Failure of Bariatric Surgery

The therapeutic problem of obesity is weight control, a major difficulty, involving a significant change in eating behavior. A number of studies show that there are many factors of resistance to weight loss whether they are physiological, genetic, environmental pressure related, or psychological and behavioral. For some patients, the surgical approach seems the best alternative. Indeed, bariatric surgery is an effective therapeutic weapon in patients with morbid obesity. However, it has been shown that approximately 25% of patients are failing at two years of this surgery (Reinhold's index). Some of the failed subjects may benefit from surgical revision. As for the others, no intervention is currently proposed to them. Studies have shown that the psychological profile of patients who are candidates for bariatric surgery is predominantly impulsive, very anxious with a tendency to depression. The stress level of these patients would be important, and they would have low self-esteem. This study hypothesize that, in these patients, the establishment of hypnotherapeutic management associated with the usual dietary monitoring could modify eating habits thus promoting weight loss and an improvement in self-esteem , stress and anxiety compared to dietary monitoring alone.

This study hypothesize that, in these patients, the establishment of hypnotherapeutic management associated with the usual dietary monitoring could modify eating habits thus promoting weight loss and an improvement in self-esteem , stress and anxiety compared to dietary monitoring alone.

There are still no studies assessing the impact of hypnotherapeutic management and self-hypnosis on the weight curve, self-esteem, stress, anxiety, or the quality of life of patients Obese in failure of bariatric surgery.

It is an Interventional, prospective, multi-center, controlled, randomized, open-label study with 2 parallel arms, evaluating the efficacy of hypnotherapeutic management in patients with bariatric surgery failure, compared to dietary monitoring alone.

Number of visits: 13 visits are planned: 1 visit of inclusion, a visit ensuring the first dietary follow-up, 9 hypnosis sessions (for the experimental group), two visits dedicated to the collection of the judgment criteria. Each patient is followed for 12 months.

The estimated duration of recruitment is 18 months.

Inclusion criteria:

• Obese patient (BMI = 30 kg / m ²)
• 18 - 65 years ( inclusive borders)
• Patient in failure of bariatric surgery and in which no surgical resumption can be proposed (in view of Reinhold's classification, the failure will be considered as a loss of overweight lower than 50 % in two years further to a bariatric surgery).
• Informed consent
• Patient in measure to realize all the visits and to follow the procedures of the study - Subject affiliated to a social security system

Exclusion criteria:

• Pregnancy current or planned during the duration of the study, pregnant or breast-feeding women
• Craniopharyngioma or any other evolutionary malignant pathology, or chronic illness in decompensation phase
• Strong probability of not compliance to the protocol or drop-out
• Psychiatric pathology of dissociated type (schizophrenia; psychosis, bipolarity …)
• Sensory (hearing, visual) or cognitive deficits susceptible to hinder the progress of the sessions.
• Incapacity to understand the nature and the purpose of the study and\or communication difficulties with the investigator

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Other: Usual Care; The control group will benefit from a standard care dietary consultation in the service and 9 dietary consultations by phone every 15 days.	Behavioral: Standard Care; The dietary advice given during these dietary consultations is part of the standard care adapted to patients who have undergone bariatric surgery while increasing the frequency of consultations (Fractionation of meals, Volume of meals, Taking meals, Drinks, Food diversity)
Other: Hypnosis; The experimental group will benefit from a dietary consultation in the service, 9 dietary consultations by telephone every 15 days to which will be associated 7 individual sessions of hypnosis and 3 individual sessions of learning to autohypnosis. A recording containing the induction of a self-hypnosis session will be given to the subject at the end of the 10 sessions, in order to promote the continuation of home-made autohypnosis.	Behavioral: Hypnosis; There ar 10 hypnosis sessions : 1st session of hypnosis : relaxation and orientation towards "emotional cleansing".; 2nd session of hypnosis: oriented towards digestion, physical and psychological; 3rd session of hypnosis: oriented towards the feeling of security.; 4th session of hypnosis: self-esteem oriented.; 5th hypnosis session: oriented towards emotional management.; 6th hypnosis session: oriented towards self-confidence.; 7th hypnosis session: oriented towards the completion of the projects.; 8th, 9th and 10th sessions: concern the learning of self-hypnosis and autonomy. A USB key containing the induction of a session of autohypnosis will be given to the subject to promote the continuation of home-made auto-hypnosis.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in weight in 5 months	Patient weight (in kg) measurement will be performed on the same scale by staff who are unaware of the patient's randomization group.	5 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in weight in 12 months	Patient weight (in kg) measurement will be performed on the same scale by staff who are unaware of the patient's randomization group.	12 months
Self-esteem	It will be evaluated by the scale of "Rosenberg's Self Esteem Scale" (1965) validated in French. It represents an assessment of the overall self-esteem that the person can have of herself. The scale includes 10 statements measured on a scale of 1 to 4.	12 months
Evolution of Quality of life	it will be evaluated by the variation of the scores obtained in the self-questionnaire EQVOD (Echelle de Qualité de Vie, Obésité et Diététique) of O. Ziegler et al (2005). It's a specific quality of life questionnaire for obese people.	12 months
Anxiety and depressive state	It will be evaluated by the Hospital Anxiety and Depression Scale - HAD (Sigmond et al, 1983). It is a self-administered 14-item questionnaire that assesses the current level of depressive and anxious symptomatology by eliminating somatic depressions that may skew assessments.	12 months
Feeding behavior	It will be evaluated by the TFEQ-R21 (Three-Factor Eating Questionnaire) self-questionnaire (Cappelleri et al, 2009). TFEQ has been validated in the general population and has been used in many studies. It explores three components of eating behavior: cognitive restriction, uncontrolled eating, and emotional eating.	12 months
Patients' satisfaction with their care	It will be evaluated the Likert scales of the self-satisfaction questionnaire. It is composed of 5 Likert scales coded from 1 to 5 which will be analyzed separately	12 months
