Introduction: The preoperative evaluation for endometriosis – more than meets the eye
It is well known that it often takes 6-10 years for endometriosis to be diagnosed in patients who have the disease, depending on where the patient lives. I certainly am not surprised. During my residency at Parkland Memorial Hospital, if a patient had chronic pelvic pain and no fibroids, her diagnosis was usually pelvic inflammatory disease. Later, during my fellowship in reproductive endocrinology at the University of Pennsylvania, the diagnosis became endometriosis.
As I gained more interest and expertise in the treatment of endometriosis, I became aware of several articles concluding that if a woman sought treatment for chronic pelvic pain with an internist, the diagnosis would be irritable bowel syndrome (IBS); with a urologist, it would be interstitial cystitis; and with a gynecologist, endometriosis. Moreover, there is an increased propensity for IBS and IC in patients with endometriosis. There also is an increased risk of small intestine bacterial overgrowth (SIBO), as noted by our guest author for this latest installment of the Master Class in Gynecologic Surgery, Iris Orbuch, MD.
Like our guest author, I have also noted increased risk of pelvic floor myalgia. Dr. Orbuch clearly outlines why this occurs. In fact, we can now understand why many patients have multiple pelvic pain–inducing issues compounding their pain secondary to endometriosis and leading to remodeling of the central nervous system. Therefore, it certainly makes sense to follow Dr. Orbuch’s recommendation for a multidisciplinary pre- and postsurgical approach “to downregulate the pain generators.”
Dr. Orbuch is a minimally invasive gynecologic surgeon in Los Angeles who specializes in the treatment of patients diagnosed with endometriosis. Dr. Orbuch serves on the Board of Directors of the Foundation of the American Association of Gynecologic Laparoscopists and has served as the chair of the AAGL’s Special Interest Group on Endometriosis and Reproductive Surgery. She is the coauthor of the book “Beating Endo – How to Reclaim Your Life From Endometriosis” (New York: HarperCollins; 2019). The book is written for patients but addresses many issues discussed in this installment of the Master Class in Gynecologic Surgery.

Patients with endometriosis and the all-too-often decade-long diagnostic delay have a variety of coexisting conditions that are pain generators – from painful bladder syndrome and pelvic floor dysfunction to a small intestine bacterial system that is significantly upregulated and sensitized.
For optimal surgical outcomes, and to help our patients recover from years of this inflammatory, systemic disease, we must treat our patients holistically and work to downregulate their pain as much as possible before excision surgery. I work with patients a few months prior to surgery, often for 4-5 months, during which time they not only see me for informative follow-ups, but also pelvic floor physical therapists, gastroenterologists, mental health professionals, integrative nutritionists, and physiatrists or pain specialists, depending on their needs.1
By identifying coexisting conditions in an initial consult and employing a presurgical multidisciplinary approach to downregulate the pain generators, my patients recover well from excision surgery, with greater and faster relief from pain, compared with those using standard approaches, and with little to no use of opioids.
At a minimum, given the unfortunate time constraints and productivity demands of working within health systems – and considering that surgeries are often scheduled a couple of months out – the surgeon could ensure that patients are engaged in at least 6-8 weeks of pelvic floor physical therapy before surgery to sufficiently lengthen the pelvic muscles and loosen surrounding fascia.
Short, tight pelvic floor muscles are almost universal in patients with delayed diagnosis of endometriosis and are significant generators of pain.
Appreciating sequelae of diagnostic delay
After my fellowship in advanced laparoscopic and pelvic surgery with Harry Reich, MD, and C. Y. Liu, MD, pioneers of endometriosis excision surgery, and as I did my residency in the early 2000s, I noticed puzzlement in the literature about why some patients still had lasting pain after thorough excision.
I didn’t doubt the efficacy of excision. It is the cornerstone of treatment, and at least one randomized double-blind trial2 and a systematic review and meta-analysis3 have demonstrated its superior efficacy over ablation in symptom reduction. What I did doubt was any presumption that surgery alone was enough. I knew there was more to healing when a disease process wreaks havoc on the body for more than a decade and that there were other generators of pain in addition to the endometriosis implants themselves.
As I began to focus on endometriosis in my own surgical practice, I strove to detect and treat endometriosis in teens. But in those patients with longstanding disease, I recognized patterns and began to more fully appreciate the systemic sequelae of endometriosis.
To cope with dysmenorrhea, patients curl up and assume a fetal position, tensing the abdominal muscles, inner thigh muscles, and pelvic floor muscles. Over time, these muscles come to maintain a short, tight, and painful state. (Hence the need for physical therapy to undo this decade-long pattern.)
Endometriosis implants on or near the gastrointestinal tract tug on fascia and muscles and commonly cause constipation, leading women to further overwork the pelvic floor muscles. In the case of diarrhea-predominant dysfunction, our patients squeeze pelvic floor muscles to prevent leakage. And in the case of urinary urgency, they squeeze muscles to release urine that isn’t really there.
As the chronic inflammation of the disease grows, and as pain worsens, the patient is increasingly in sympathetic overdrive (also known as ”fight or flight”), as opposed to a parasympathetic state (also known as “rest and digest”). The bowel’s motility slows, allowing the bacteria of the small intestine to grow beyond what is normal, leading to SIBO, a condition increasingly recognized by gastroenterologists and others that can impede nutrient absorption and cause bloat and pain and exacerbate constipation and diarrhea.
Key to my conceptualization of pain was a review published in 2011 by Pam Stratton, MD, of the National Institutes of Health, and Karen J. Berkley, PhD, then of Florida State University, on chronic pain and endometriosis.4 They detailed how endometriotic lesions can develop their own nerve supply that interacts directly and in a two-way fashion with the CNS – and how the lesions can engage the nervous system in ways that create comorbid conditions and pain that becomes “independent of the disease itself.”
Sensitized peripheral nerve fibers innervating a deeply infiltrating lesion on the left uterosacral ligament, for instance, can sensitize neurons in the spinal sacral segment. Branches of these nerve fibers can extend to other segments of the spinal cord, and, once sensitized themselves, turn on neurons in these other segments. There is a resultant remodeling of the central nervous system, in essence, and what is called “remote central sensitization.” The CNS becomes independent from peripheral neural processes.
I now explain to both patients and physicians that those who have had endometriosis for years have had an enduring “hand on the stove,” with a persistent signal to the CNS. Tight muscles are a hand on the stove, painful bladder syndrome is another hand on the stove, and SIBO is yet another. So are anxiety and depression.
The CNS becomes so upregulated and overloaded that messages branch out through the spinal cord to other available pathways and to other organs, muscles, and nerves. The CNS also starts firing on its own – and once it becomes its own pain generator, taking one hand off the stove (for instance, excising implants) while leaving multiple other hands on the hot stove won’t remove all pain. We must downregulate the CNS more broadly.
As I began addressing pain generators and instigators of CNS sensitization – and waiting for excision surgery until the CNS had sufficiently cooled – I saw that my patients had a better chance of more significant and lasting pain relief.
Pearls for a multimodal approach
My initial physical exam includes an assessment of the pelvic floor for overly tight musculature. An abdominal exam will usually reveal whether there is asymmetry of the abdominal wall muscles, which typically informs me of the likelihood of tightness and pulling on either side of the pelvic anatomy. On the internal exam, then, the pelvic floor muscles can be palpated and assessed. These findings will guide my referrals and my discussions with patients about the value of pelvic floor physical therapy. The cervix should be in the midline of the vagina – equidistant from the left and right vaginal fornices. If the cervix is pulled away from this midline, and a palpation of a thickened uterosacral ligament reproduces pain, endometriosis is 90% likely.
Patients who report significant “burning” pain that’s suggestive of neuropathic pain should be referred to a physical medicine rehabilitation physician or a pain specialist who can help downregulate their CNS. And patients who have symptoms of depression, anxiety disorders (including obsessive-compulsive disorder), or posttraumatic stress disorder should be referred to pain therapists, psychologists, or other mental health professionals, preferably well before surgery. I will also often discuss mindfulness practices and give my patients “meditation challenges” to achieve during the presurgical phase.
Additional points of emphasis about a multidisciplinary, multimodal approach include:
Advanced pelvic floor therapy: Therapists with specialized training in pelvic health and manual therapy utilize a range of techniques and modalities to release tension in affected muscles, fascia, nerves, and bone, and in doing so, they help to downregulate the CNS. Myofascial release, myofascial trigger point release, neural mobilization, and visceral mobilization are among these techniques. In addition to using manual therapy, many of these therapists may also employ neuromuscular reeducation and other techniques that will be helpful for the longer term.
It is important to identify physical therapists who have training in this approach; women with endometriosis often have a history of treatment by physical therapists whose focus is on incontinence and muscle strengthening (that is, Kegel exercises), which is the opposite of what endometriosis patients need.
Treating SIBO: Symptoms commonly associated with SIBO often overlap with symptoms of irritable bowel syndrome (IBS) – namely constipation, diarrhea (or both), and bloating. Indeed, many patients with undiagnosed endometriosis have been diagnosed with IBS. I send every patient who has one of these symptoms for SIBO breath testing, which utilizes carbohydrate substrates (glucose or lactulose) and measures hydrogen and/or methane in the breath.
SIBO is typically treated with rifampin, which stays in the small bowel and will not negatively affect beneficial bacteria, with or without neomycin. Gastroenterologists with more integrative practices also consider the use of herbals in addition to – or instead of – antibiotics. It can sometimes take months or a couple of years to correct SIBO, depending on how long the patient has been affected, but with presurgical diagnosis and a start on treatment, we can remove or at least tone down another instigator of CNS sensitization.
I estimate that 80% of my patients have tested positive for SIBO. Notably, in a testament to the systemic nature of endometriosis, a study published in 2009 of 355 women undergoing operative laparoscopy for suspected endometriosis found that 90% had gastrointestinal symptoms, but only 7.6% of the vast majority whose endometriosis was confirmed were found to have endometrial implants on the bowel itself.5
Addressing bladder issues: I routinely administer the PUF (Pain, Urgency, Frequency) questionnaire as part of my intake package and follow it up with conversation. For just about every patient with painful bladder syndrome, pelvic floor physical therapy in combination with a low-acid, low-potassium diet will work effectively together to reduce symptoms and pain. The IC Network offers a helpful food list, and patients can be counseled to choose foods that are also anti-inflammatory. When referrals to a urologist for bladder instillations are possible, these can be helpful as well.
Our communication with patients
Our patients need to have their symptoms and pain validated and to understand why we’re recommending these measures before surgery. Some education is necessary. Few patients will go to an integrative nutritionist, for example, if we just write a referral without explaining how years of inflammation and disruption in the gut can affect the whole body – including mental health – and that it can be corrected over time.
Also necessary is an appreciation of the fact that patients with delayed diagnoses have lived with gastrointestinal and other symptoms and patterns for so long – and often have mothers whose endometriosis caused similar symptoms – that some of their own experiences can seem almost “normal.” A patient whose mother had bowel movements every 7 days may think that 4-5 day intervals are acceptable, for instance. This means we have to carefully consider how we ask our questions.
I always ask my patients as we’re going into surgery, what percentage better are you? I’ve long aimed for at least 30% improvement, but most of the time, with pelvic floor therapy and as many other pain-generator–focused measures as possible, we’re getting them 70% better.
Excision surgery will remove the inflammation that has helped fuel the SIBO and other coconditions. Then, everything done to prepare the body must continue for some time. Certain practices, such as eating an anti-inflammatory diet, should be lifelong.
One day, it is hoped, a pediatrician or other physician will suspect endometriosis early on. The patient will see the surgeon within several months of the onset of pain, and we won’t need to unravel layers of pain generation and CNS upregulation before operating. But until this happens and we shorten the diagnostic delay, we must consider the benefits of presurgical preparation.

My initial physical exam includes an assessment of the pelvic floor for overly tight musculature. An abdominal exam will usually reveal whether there is asymmetry of the abdominal wall muscles, which typically informs me of the likelihood of tightness and pulling on either side of the pelvic anatomy. On the internal exam, then, the pelvic floor muscles can be palpated and assessed. These findings will guide my referrals and my discussions with patients about the value of pelvic floor physical therapy. The cervix should be in the midline of the vagina – equidistant from the left and right vaginal fornices. If the cervix is pulled away from this midline, and a palpation of a thickened uterosacral ligament reproduces pain, endometriosis is 90% likely.
Patients who report significant “burning” pain that’s suggestive of neuropathic pain should be referred to a physical medicine rehabilitation physician or a pain specialist who can help downregulate their CNS. And patients who have symptoms of depression, anxiety disorders (including obsessive-compulsive disorder), or posttraumatic stress disorder should be referred to pain therapists, psychologists, or other mental health professionals, preferably well before surgery. I will also often discuss mindfulness practices and give my patients “meditation challenges” to achieve during the presurgical phase.
Additional points of emphasis about a multidisciplinary, multimodal approach include:
Advanced pelvic floor therapy: Therapists with specialized training in pelvic health and manual therapy utilize a range of techniques and modalities to release tension in affected muscles, fascia, nerves, and bone, and in doing so, they help to downregulate the CNS. Myofascial release, myofascial trigger point release, neural mobilization, and visceral mobilization are among these techniques. In addition to using manual therapy, many of these therapists may also employ neuromuscular reeducation and other techniques that will be helpful for the longer term.
It is important to identify physical therapists who have training in this approach; women with endometriosis often have a history of treatment by physical therapists whose focus is on incontinence and muscle strengthening (that is, Kegel exercises), which is the opposite of what endometriosis patients need.
Treating SIBO: Symptoms commonly associated with SIBO often overlap with symptoms of irritable bowel syndrome (IBS) – namely constipation, diarrhea (or both), and bloating. Indeed, many patients with undiagnosed endometriosis have been diagnosed with IBS. I send every patient who has one of these symptoms for SIBO breath testing, which utilizes carbohydrate substrates (glucose or lactulose) and measures hydrogen and/or methane in the breath.
SIBO is typically treated with rifampin, which stays in the small bowel and will not negatively affect beneficial bacteria, with or without neomycin. Gastroenterologists with more integrative practices also consider the use of herbals in addition to – or instead of – antibiotics. It can sometimes take months or a couple of years to correct SIBO, depending on how long the patient has been affected, but with presurgical diagnosis and a start on treatment, we can remove or at least tone down another instigator of CNS sensitization.
I estimate that 80% of my patients have tested positive for SIBO. Notably, in a testament to the systemic nature of endometriosis, a study published in 2009 of 355 women undergoing operative laparoscopy for suspected endometriosis found that 90% had gastrointestinal symptoms, but only 7.6% of the vast majority whose endometriosis was confirmed were found to have endometrial implants on the bowel itself.5
Addressing bladder issues: I routinely administer the PUF (Pain, Urgency, Frequency) questionnaire as part of my intake package and follow it up with conversation. For just about every patient with painful bladder syndrome, pelvic floor physical therapy in combination with a low-acid, low-potassium diet will work effectively together to reduce symptoms and pain. The IC Network offers a helpful food list, and patients can be counseled to choose foods that are also anti-inflammatory. When referrals to a urologist for bladder instillations are possible, these can be helpful as well.
Our communication with patients
Our patients need to have their symptoms and pain validated and to understand why we’re recommending these measures before surgery. Some education is necessary. Few patients will go to an integrative nutritionist, for example, if we just write a referral without explaining how years of inflammation and disruption in the gut can affect the whole body – including mental health – and that it can be corrected over time.
Also necessary is an appreciation of the fact that patients with delayed diagnoses have lived with gastrointestinal and other symptoms and patterns for so long – and often have mothers whose endometriosis caused similar symptoms – that some of their own experiences can seem almost “normal.” A patient whose mother had bowel movements every 7 days may think that 4-5 day intervals are acceptable, for instance. This means we have to carefully consider how we ask our questions.
I always ask my patients as we’re going into surgery, what percentage better are you? I’ve long aimed for at least 30% improvement, but most of the time, with pelvic floor therapy and as many other pain-generator–focused measures as possible, we’re getting them 70% better.
Excision surgery will remove the inflammation that has helped fuel the SIBO and other coconditions. Then, everything done to prepare the body must continue for some time. Certain practices, such as eating an anti-inflammatory diet, should be lifelong.
One day, it is hoped, a pediatrician or other physician will suspect endometriosis early on. The patient will see the surgeon within several months of the onset of pain, and we won’t need to unravel layers of pain generation and CNS upregulation before operating. But until this happens and we shorten the diagnostic delay, we must consider the benefits of presurgical preparation.

I certainly am not surprised. During my residency at Parkland Memorial Hospital, if a patient had chronic pelvic pain and no fibroids, her diagnosis was usually pelvic inflammatory disease. Later, during my fellowship in reproductive endocrinology at the University of Pennsylvania, the diagnosis became endometriosis. </p> <p>As I gained more interest and expertise in the treatment of endometriosis, I became aware of several articles concluding that if a woman sought treatment for chronic pelvic pain with an internist, the diagnosis would be irritable bowel syndrome (IBS); with a urologist, it would be interstitial cystitis; and with a gynecologist, endometriosis. Moreover, there is an increased propensity for IBS and IC in patients with endometriosis. There also is an increased risk of small intestine bacterial overgrowth (SIBO), as noted by our guest author for this latest installment of the Master Class in Gynecologic Surgery, Iris Orbuch, MD. <br/><br/>Like our guest author, I have also noted increased risk of pelvic floor myalgia. Dr. Orbuch clearly outlines why this occurs. In fact, we can now understand why many patients have multiple pelvic pain–inducing issues compounding their pain secondary to endometriosis and leading to remodeling of the central nervous system. Therefore, it certainly makes sense to follow Dr. Orbuch’s recommendation for a multidisciplinary pre- and postsurgical approach “to downregulate the pain generators.”<br/><br/>Dr. Orbuch is a minimally invasive gynecologic surgeon in Los Angeles who specializes in the treatment of patients diagnosed with endometriosis.

He has no conflicts of interest to report.<br/><br/></em> </p> <p>Patients with endometriosis and the all-too-often decade-long diagnostic delay have a variety of coexisting conditions that are pain generators – from painful bladder syndrome and pelvic floor dysfunction to a small intestine bacterial system that is significantly upregulated and sensitized. </p> <p>For optimal surgical outcomes, and to help our patients recover from years of this inflammatory, systemic disease, we must treat our patients holistically and work to downregulate their pain as much as possible before excision surgery. I work with patients a few months prior to surgery, often for 4-5 months, during which time they not only see me for informative follow-ups, but also pelvic floor physical therapists, gastroenterologists, mental health professionals, integrative nutritionists, and physiatrists or pain specialists, depending on their needs.<sup>1</sup><br/><br/>By identifying coexisting conditions in an initial consult and employing a presurgical multidisciplinary approach to downregulate the pain generators, my patients recover well from excision surgery, with greater and faster relief from pain, compared with those using standard approaches, and with little to no use of opioids. <br/><br/>At a minimum, given the unfortunate time constraints and productivity demands of working within health systems – and considering that surgeries are often scheduled a couple of months out – the surgeon could ensure that patients are engaged in at least 6-8 weeks of pelvic floor physical therapy before surgery to sufficiently lengthen the pelvic muscles and loosen surrounding fascia. <br/><br/>Short, tight pelvic floor muscles are almost universal in patients with delayed diagnosis of endometriosis and are significant generators of pain. <br/><br/></p> <h2>Appreciating sequelae of diagnostic delay</h2> <p>After my fellowship in advanced laparoscopic and pelvic surgery with Harry Reich, MD, and C. Y. Liu, MD, pioneers of endometriosis excision surgery, and as I did my residency in the early 2000s, I noticed puzzlement in the literature about why some patients still had lasting pain after thorough excision. </p> <p>I didn’t doubt the efficacy of excision. It is the cornerstone of treatment, and at least one randomized double-blind trial<sup>2 </sup>and a systematic review and meta-analysis<sup>3</sup> have demonstrated its superior efficacy over ablation in symptom reduction. What I did doubt was any presumption that surgery alone was enough. I knew there was more to healing when a disease process wreaks havoc on the body for more than a decade and that there were other generators of pain in addition to the endometriosis implants themselves. <br/><br/>As I began to focus on endometriosis in my own surgical practice, I strove to detect and treat endometriosis in teens. But in those patients with longstanding disease, I recognized patterns and began to more fully appreciate the systemic sequelae of endometriosis. <br/><br/>To cope with dysmenorrhea, patients curl up and assume a fetal position, tensing the abdominal muscles, inner thigh muscles, and pelvic floor muscles. Over time, these muscles come to maintain a short, tight, and painful state. (Hence the need for physical therapy to undo this decade-long pattern.)<br/><br/>Endometriosis implants on or near the gastrointestinal tract tug on fascia and muscles and commonly cause constipation, leading women to further overwork the pelvic floor muscles. In the case of diarrhea-predominant dysfunction, our patients squeeze pelvic floor muscles to prevent leakage. And in the case of urinary urgency, they squeeze muscles to release urine that isn’t really there. <br/><br/>As the chronic inflammation of the disease grows, and as pain worsens, the patient is increasingly in sympathetic overdrive (also known as ”fight or flight”), as opposed to a parasympathetic state (also known as “rest and digest”). The bowel’s motility slows, allowing the bacteria of the small intestine to grow beyond what is normal, leading to SIBO, a condition increasingly recognized by gastroenterologists and others that can impede nutrient absorption and cause bloat and pain and exacerbate constipation and diarrhea.<br/><br/>Key to my conceptualization of pain was a review published in 2011 by Pam Stratton, MD, of the National Institutes of Health, and Karen J. Berkley, PhD, then of Florida State University, on chronic pain and endometriosis.<sup>4</sup> They detailed how endometriotic lesions can develop their own nerve supply that interacts directly and in a two-way fashion with the CNS – and how the lesions can engage the nervous system in ways that create comorbid conditions and pain that becomes “independent of the disease itself.” <br/><br/>Sensitized peripheral nerve fibers innervating a deeply infiltrating lesion on the left uterosacral ligament, for instance, can sensitize neurons in the spinal sacral segment. Branches of these nerve fibers can extend to other segments of the spinal cord, and, once sensitized themselves, turn on neurons in these other segments. There is a resultant remodeling of the central nervous system, in essence, and what is called “remote central sensitization.” The CNS becomes independent from peripheral neural processes. <br/><br/>I now explain to both patients and physicians that those who have had endometriosis for years have had an enduring “hand on the stove,” with a persistent signal to the CNS. Tight muscles are a hand on the stove, painful bladder syndrome is another hand on the stove, and SIBO is yet another. So are anxiety and depression. <br/><br/>The CNS becomes so upregulated and overloaded that messages branch out through the spinal cord to other available pathways and to other organs, muscles, and nerves. The CNS also starts firing on its own – and once it becomes its own pain generator, taking one hand off the stove (for instance, excising implants) while leaving multiple other hands on the hot stove won’t remove all pain. We must downregulate the CNS more broadly.<br/><br/>As I began addressing pain generators and instigators of CNS sensitization – and waiting for excision surgery until the CNS had sufficiently cooled – I saw that my patients had a better chance of more significant and lasting pain relief.<br/><br/></p> <h2>Pearls for a multimodal approach</h2> <p>My initial physical exam includes an assessment of the pelvic floor for overly tight musculature.
