Endometriosis and Pain (EndoDOL)

New Perioperative and Non-pharmacological Practices in Endometriosis at the Crossroad of Gynecology and Chronic Pain

Endometriosis is a condition affecting about 10% of childbearing age women. It can begin a few months to a few years after puberty. It causes abdominal and pelvic pain that can be extremely debilitating, affecting the quality of patients life by affecting sexuality and fertility. Psychological repercussions are very important and underestimated. Patient care focuses most often on the "organ pathology treatment ".

This study proposes to evaluate a multidisciplinary patient care by insisting on anatomo-physiological pain management, psychological and bodily, in the perioperative phase.

The main objective is to evaluate benefit of psychological and corporal group management on the overall quality of life of patients with severe endometriosis in terms of endometriotic damage and/or functional and painful repercussions, requiring surgery, before or after this study

Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: Patients suffering from severe endometriosis and chronic pain; Patients suffering from severe endometriosis and chronic pain that have been identified during a gynecological consultation (individual or during a multidisciplinary team meetings) or during a pain consultation on the same site of the Croix-Rousse Hospital and having signed a consent form

Behavioral: Psychological and corporal group management; After inclusion, patient will be divided into groups of 6 or 8 patients either in pre-operative or post-operative phase. Patient care will take place entirely in pre-operative or post-operative phase. Each group will benefit of six one hour and a half sessions. The frequency is established as follows: First week a session of Body Strategy ©; Second week a psychological session with group of speech (Photolanguage ©).; Third week is a break Then the cycle currently described is repeated, for a total of 6 alternate sessions

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Evolution of Physical Component Score (PCS) assessed by the Medical Outcome Study Short Form -36 (MOS SF 36) scale	The Physical Composite Score (PCS) is based on four physical dimensions of quality of life and involves 8 components (Physical Functioning, Role Physical, Bodily Pain,General Health, Vitality, Social Functioning,Mental Health and Emotional Role). The evolution of the PCS is measured between T0, start of care, and the end of care (at T0 + 3 months). The PCS score ranges from 0 to 100, a higher score being associated with a better quality of life.	at 3 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Evolution of pain: Visual Analogue Scale (VAS)	Evolution of pain assessed by the Visual Analogue Scale (VAS) between the beginning (T0) and the end of patient care (T0 + 3 months), in different body areas (back - abdomen - pelvic area - others) The VAS allows patients to rate their pain in an objective and comparable measure. This allows a quantitative evaluation of intensity of pain and trace evolution of the symptomatology in the same subject. The VAS ranges from 0 to 10, 0 for no pain, 10 for maximum pain.	at 3 months
Evolution of overall pain: Visual Analogue Scale (VAS)	Evolution of overall pain assessed by the Visual Analogue Scale (VAS) between the beginning (T0) and the end of patient care (T0 + 3 months) The VAS allows patients to rate their pain in an objective and comparable measure. This allows a quantitative evaluation of intensity of pain and trace evolution of the symptomatology in the same subject. The VAS ranges from 0 to 10, 0 for no pain, 10 for maximum pain.	at 3 months
Comparison of painful location on the body pain schema, before/after patient care	Comparison of painful location (circle by the patient on the body schema) before (T0)/after patient care (T0 + 3 months). Since endometriosis is synonymous with chronic and specific chronic pain (dyspareunia, dyschesia, cystalgia, for example), the body pain schema is a complementary tool in measurements, where the patient precisely surrounds the painful location (localizations of pain) and their extensions on a body schema,	at 3 months
Comparison of area of pain on the body pain schema, before/after patient care	Comparison of area of pain (circle by the patient on the body schema), before (T0)/after patient care (T0 + 3 months). Area of each pain location will be calculated using the Geocalcul.Plus software and will be compared between the beginning (T0) and the end of patient care (T0 + 3 months).	at 3 months
Comparison of results of the interview schedule	Comparison of results of the interview schedule before (T0) and after patient care (T0 + 3 months). Interview schedule examines two dimensions : Inter-individual: couple quality of life, sex life; Intra-individual: self-image/body image, infertility, emotional life, pre or postoperative felt	at 3 months
Evolution of analgesics consumption	Consumption of analgesics at the end of the treatment (T0 + 3 months) is self-evaluated by the patient: decreased / stable / increased.	at 3 months
number of painful crises	Number of painful crises is the comparison of seizures number in the month preceding treatment with seizures number in the last month of care	at 3 months
Evolution of the Vitality (VT) score of the MOS SF36 score, before/after treatment	The evolution of the Vitality (VT) score is determined by the MOS SF36 and measured between T0, start of care, and the end of care (at T0 + 3 months). The VT score ranges from 0 to 100, a higher score being associated with a better quality of life.	at 3 months
Evolution of the Social Function (SF) score of the MOS SF36 score, before/after treatment	The evolution of the Social Function (SF) score is determined by the MOS SF36 and measured between T0, start of care, and the end of care (at T0 + 3 months). The SF score ranges from 0 to 100, a higher score being associated with a better quality of life.	at 3 months
Evolution of the Mental Health (MH) score of the MOS SF36 score, before/after treatment	The evolution of the Mental Health (MH) score is determined by the MOS SF36 and measured between T0, start of care, and the end of care (at T0 + 3 months). The MH score ranges from 0 to 100, a higher score being associated with a better quality of life.	at 3 months
Evolution of the Role Emotional (RE) score of the MOS SF36 score, before/after treatment	The evolution of the Role Emotional (RE) score is determined by the MOS SF36 and measured between T0, start of care, and the end of care (at T0 + 3 months). The RE score ranges from 0 to 100, a higher score being associated with a better quality of life.	at 3 months
Evolution of the Physical Function (PF) score of the MOS SF36 score, before/after treatment	The evolution of the Physical Function (PF) score is determined by the MOS SF36 and measured between T0, start of care, and the end of care (at T0 + 3 months). The PF score ranges from 0 to 100, a higher score being associated with a better quality of life.	at 3 months
Evolution of the Role Physical (RP) score of the MOS SF36 score, before/after treatment	The evolution of the Role Physical (RP) score is determined by the MOS SF36 and measured between T0, start of care, and the end of care (at T0 + 3 months). The RP score ranges from 0 to 100, a higher score being associated with a better quality of life.	at 3 months
Evolution of the Bodily Pain (BP) score of the MOS SF36 score, before/after treatment	The evolution of the Bodily Pain (BP) score is determined by the MOS SF36 and measured between T0, start of care, and the end of care (at T0 + 3 months). The BP score ranges from 0 to 100, a higher score being associated with a better quality of life.	at 3 months
Evolution of the General Health (GH) score of the MOS SF36 score, before/after treatment	The evolution of the General Health (GH) score is determined by the MOS SF36 and measured between T0, start of care, and the end of care (at T0 + 3 months).
