Physiotherapy of the Pelvic Floor in Women With Deep Infiltrating Endometriosis (endofisio-01)

Evaluation of the Efficacy of Pelvic Floor Physiotherapy in Symptomatic Patients Affected by Deep Infiltrating Endometriosis

The aim of our study is to evaluate the impact of pelvic floor physiotherapy in symptomatic patients affected by deep infiltrating endometriosis, using 3D/4D transperineal ultrasound for evaluation of pelvic floor morphometry, NRS (Numerical Rating Scale) for evaluation of symptoms and validated questionnaires investigating intestinal, sexual and urinary functions. These results will be compared with those obtained from symptomatic patients affected by deep infiltrating endometriosis following the standard care procedure that does not provide pelvic floor physiotherapy.

Symptomatic, nulliparous women with deep infiltrating endometriosis are included in the study. During the first medical examination, endometriosis related symptoms are assessed using NRS (Numerical Rating Scale); intestinal, sexual and urinary functions are evaluated with validated questionnaires (Knowles-Eccersley-Scott-Symptom Questionnaire (KESS), Female Sexual Function Index (FSFI), Bristol Female Lower Urinary Tract Symptoms (BFLUTS)); pelvic floor morphometry at rest, during pelvic floor contraction and during Valsalva manoeuvre is evaluated using 3D/4D transperineal ultrasound through the assessment of the levator hiatus area (LHA). Gynaecological examination, transvaginal and transabdominal ultrasound are performed. After the first medical examination, enrolled patients are randomized into two groups: patients in Group A receive standard care procedure and pelvic floor physiotherapy; patients in Group B receive standard care procedure only. Pelvic floor physiotherapy protocol consists of six sessions (weeks 1, 3, 5, 8, 11 from the randomization). After four months from the first medical examination, endometriosis related symptoms, intestinal, sexual and urinary functions and pelvic floor morphometry are reassessed for all patients, using the same procedures, comparing the two groups and evaluating the impact of pelvic floor physiotherapy.

six individual sessions (weeks 1, 3 , 5, 8, 11 from the randomization) with pelvic floor consciousness exercises with mild contractions and relaxation (ex. 'kegel reverse' exercises); respiratory rate control exercises; extra exercises to perform at home are suggested.

Evaluation of the impact of pelvic floor physiotherapy on pelvic floor muscles contraction and pain using a gynecological examination and ultrasounds. All scans are obtained using a Voluson E6 system (GE Healthcare, Zipf, Austria) with RAB 8-4-MHz volume transducer for all acquisitions. Measurements were evaluated using a dedicated software (4DView 14.4; GE Healthcare, Zipf, Austria).

Women are firstly asked to rest and then contract the pelvic floor muscles (PFM) until the maximal cranioanterior displacement of the anorectal angle is attained. The anorectal angle is defined as the angle between the posterior wall of the rectal ampulla and the anal canal. All scans are obtained using a Voluson E6 system (GE Healthcare, Zipf, Austria) with RAB 8-4-MHz volume transducer for all acquisitions. Measurements were evaluated using a dedicated software (4DView 14.4; GE Healthcare, Zipf, Austria).

Patients are firstly asked to rest and then contract the pelvic floor muscles looking at the ultrasound screen in order to be aware of the contraction of the pelvic floor muscles and improve it. Voluson E6 system (GE Healthcare, Zipf, Austria) with RAB 8-4-MHz volume transducer is used for all acquisitions.

Inclusion Criteria: Patients with clinical and ultrasound diagnosis of deep endometriosis with related symptoms (chronic pelvic pain, dysmenorrhea, dyschezia, dyspareunia, dysuria) Nulliparity Obtaining Informed Consent Exclusion Criteria: Patients with an oncological disease or needing surgery for malignant pathologies Urogenital prolapse History of surgery for deep infiltrating endometriosis Congenital or acquired malformations of pelvis and pelvic floor History of diseases characterised by chronic pelvic pain (interstitial cystitis, irritable bowel disease, chronic vulvodynia).
