Preoperative Hypnosis in Gynecology (HYPPOGYN)

May 11, 2026 updated by: University Hospital, Bordeaux

Exploratory Study of the Impact of a Preoperative Formal Hypnosis Session on Perioperative Anxiety Among Female Patients Hospitalised for Hysterectomy Due to Pelvic Gynecological Cancer

The research hypotheses that preoperative formal hypnosis session reduces perioperative anxiety among women undergoing a hysterectomy for pelvic gynecological cancer. The key objective is to estimate the effect of preoperative hypnosis on preoperative anxiety among this population

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Anxiety is present preoperatively in 40% of patients. The operated subjects are on average 20% more anxious than the general population, according to a study of 2013. Cancer as well as surgery modifying the body pattern and impairing femininity are risk factors for preoperative anxiety. Recent work in both children and adults has shown that significant levels of preoperative anxiety increase the risk of postoperative complications and the occurrence of postoperative emotional and behavioral disorders. The consequences of hysterectomy increase patients' anxiety, for fear of affecting femininity, and the modification of the body regimen. The prevention of preoperative anxiety in such population is therefore a major issue.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • ≥ 18yrs with pelvic gynecological cancer (endometrium, cervix, ovary),
  • at any stage of the disease;
  • patient coming for anesthesia consultation before hysterectomy,
  • informed signed consent,
  • patient affiliated to or beneficiary of social security.

Exclusion Criteria:

  • patient <18yrs,
  • patient with a pelvic gynecological cancer that does not require hysterectomy;
  • patient with psychiatric history or a depressive syndrome;
  • deaf patient (deafness makes the hypnosis session impossible),
  • patient under legal protection.

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Interventional arm
Caregiver Accompaniment Time (CAT) + preoperative hypnosis session (experimental arm): The hypnosis session is performed by a nurse trained in medical hypnosis; this interview lasts approximately one hour and is carried out 5 to 15 days before the hospitalisation. During the hypnosis session, the patient is free to choose what issues she wants to address. The patient will then go from a state of ordinary consciousness to a modified state of consciousness. This state will allow her to activate her own resources to handle difficulties, especially anxiety. Using a post-hypnotic suggestion, the patient will be able to revisit her work at any time she needs
Behavioral: Caregiver Accompaniment Time (CAT) + preoperative hypnosis session
The hypnosis session is performed by a nurse trained in medical hypnosis; this interview lasts approximately one hour and is carried out 5 to 15 days before the hospitalisation. During the hypnosis session, the patient is free to choose what issues she wants to address. The patient will then go from a state of ordinary consciousness to a modified state of consciousness. This state will allow her to activate her own resources to handle difficulties, especially anxiety. Using a post-hypnotic suggestion, the patient will be able to revisit her work at any time she needs
No Intervention: Control (CAT)
CAT is performed in routine care for all patients after the announcement of the illness by a trained nurse, if possible on the same day as the consultation or before the consultation of anesthesia. This is an interview of approximately 45 minutes to listen to the patient, to answer her questions and to re-explain the information delivered to her. The patient will tackle the history of the disease and then the treatment, this time dedicated evolves according to the desire of the patient and her ability to accept the disease. The patient can express her feelings, then the family circle is evoked talking about the resource persons and the future. The purpose of this interview is to obtain the autonomy of the patient by the setting up of supportive care

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Time Frame: 1 month after the surgery
visual analog scale (from 0, no anxiety to 10, extreme anxiety)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
