Study summary

Endometriosis is a chronic inflammatory condition where there is abnormal tissue growing in the pelvis or other places in the body that resembles the lining of the uterus (endometrium), and is a common cause of long lasting pelvic pain. Surgery is sometimes done for endometriosis to help people with pain, however it is common for people to have some pain after surgery that doesn't go away. This may be related to other painful things like muscle pain in the pelvis, bowel or bladder issues, or mental health conditions.

Researchers would like to know if doing pelvic floor physiotherapy before surgery for endometriosis will help people with long lasting pain after surgery.

Participants in the study will be randomly put into one of two groups: the intervention group, who will receive two to three structured in-person pelvic floor physiotherapy sessions prior to surgery ("prehabilitation"), in addition to usual surgical care, or the control group, who will receive usual surgical care, and may still access physiotherapy outside of the study if they want to. All participants will complete questionnaires before surgery, after completing prehabilitation or immediately before surgery if they are part of the control group, approximately 6 weeks after surgery, 6 months after surgery, and 12 months after surgery. The questionnaires ask about endometriosis-related pain, quality of life, bladder and bowel symptoms, and mental well-being.

Read the detailed description

Introduction: Endometriosis is a chronic inflammatory gynecologic condition characterized by growth of ectopic endometrial-like tissue within and outside of the pelvis, and is a common cause of chronic pelvic pain. Surgical management, including fertility-sparing endometriosis surgery or hysterectomy, is frequently performed with the goal of improving pain and quality of life; however, persistent or recurrent pain after endometriosis surgery is not uncommon. Factors contributing to ongoing pain may include conditions that are present before surgery including myofascial pelvic pain, psychological factors, or the presence of other comorbid chronic pain conditions, sometimes culminating in complex pain syndromes and central nervous system sensitization. "Prehabilitation", defined a structured intervention such as physiotherapy, exercise, and dietary changes, have been shown to improve perioperative outcomes in several surgical specialties, including gynecologic oncology, colorectal surgery, and orthopedic surgery. Pelvic floor physiotherapy has been shown to improve endometriosis-related pain symptoms and functional outcomes. Despite indirect data showing benefits, the quantitative and qualitative effect of prehabilitation in individuals undergoing endometriosis surgery for pelvic pain remains unknown.

Aim: To investigate the impact of structured preoperative pelvic physiotherapy in patients with pelvic pain undergoing endometriosis surgery (fertility sparing surgery and hysterectomy)

Objectives:

  1. Determine the effect of pelvic physiotherapy prehabilitation on quality of life, measured by Endometriosis Health Profile (EHP)-30 scale (primary outcome)
  2. Examine the impact of pelvic physiotherapy prehabilitation on chronic pelvic, dysmenorrhea, dyspareunia, symptoms of irritable bowel syndrome (IBS) and painful bladder syndrome (PBS), and psychologic indices including depression, anxiety and pain catastrophizing (secondary outcomes) Hypothesis: Patients receiving structured preoperative pelvic floor physiotherapy ("prehabilitation") will have improved post-operative pain scores and improved quality of life compared to those receiving standard care.

Methods: This study is a prospective, single-center, double arm, non-blinded randomized controlled trial evaluating the effect of preoperative pelvic floor physiotherapy ("prehabilitation") on pre- and post- operative pain and quality of life outcomes in patients with pelvic pain undergoing surgery for endometriosis (fertility sparing or hysterectomy). Participants aged 18-50 will be screened for eligibility from the Chronic Pelvic Pain (CPP) clinic in Edmonton, Alberta at the Lois Hole Hospital for Women. Eligible and willing participants will undergo randomization in a 1:1 ratio to receive either structured preoperative pelvic floor physiotherapy (2-3 sessions within 6 months leading up to surgery), in addition to standard perioperative care (intervention group) or standard perioperative care alone (control group). Surgery will be performed by fellowship trained minimally invasive gynecologic surgeons at the Royal Alexandra Hospital in Edmonton, AB. Participants will complete questionnaires at baseline, after prehabilitation is complete before surgery, 6-8 weeks post operatively, and 6 months and 12 months post operatively. Baseline demographic information will be collected including age, BMI, gynecologic surgical history, hormone use, and analgesic use. The primary outcome measure of this study is the Endometriosis Health Profile (EHP)-30 score (measures quality of life) over these timepoints. Secondary outcomes include measurements of chronic pelvic pain, dysmenorrhea, dyspareunia (numerical rating scale), presence of IBS and PBS, Central Sensitization Inventory (CSI), Pain Catastrophizing Scale (PCS), and assessment for depression through the Patient Health Questionnaire-9 (PHQ-9), and presence of generalized anxiety disorder through the GAD-7 questionnaire. Data will be stratified by the type of surgery patients received (hysterectomy or fertility-sparing endometriosis surgery) and stage of endometriosis (stage I/II or stage III/IV).

Expected outcomes and significance: If effective, preoperative pelvic floor physiotherapy may represent a low-risk intervention to improve overall pain and quality of life in patients undergoing endometriosis surgery. Findings could inform the creation of standardized care pathways for patients seeking care for chronic pelvic pain, improve outcomes in patients undergoing surgery for endometriosis, and decrease healthcare utilization after surgery which could have a major positive economic impact as well.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Mar 2027; primary completion for Mar 2030, 36 months later.

Of 196 non-industry interventional studies with no phase under Endometriosis, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 13 and three quarters within 44. This study's planned 36 months is above that.

Counting every sponsor, half of 211 studies reached it within 25 months; a quarter within 13 and three quarters within 44.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 18, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
