acupuncture, Chinese herbal medicine, and hypnotherapy may have roles to play in the treatment of dysmenorrhea, endometriosis, irritable bowel syndrome, and pelvic inflammatory disease, either as adjuncts or as alternatives to conventional treatments Unfortunately the current evidence lacks rigor and the available trials are frequently small, poorly designed, and inadequately reported As a consequence, we can only consider this preliminary evidence This area clearly requires further more rigorous investigation Research into CAM therapies will, however, take time and require considerable resources, so women with CPP seeking alternatives to conventional treatments are likely to seek advice and treatment before the necessary research is undertaken Patients wishing to use CAM options should be informed of the very provisional nature of the evidence supporting these approaches They should also be encouraged to only receive treatment from professionally registered CAM practitioners using, in the instance of herbal treatments, approved herbal suppliers and herbal products with a good manufacturing practice certification This will ensure that, while the effectiveness of CAM interventions remains unproven, these treatments are unlikely to harm and may contribute to relieving the symptoms of this problematic condition References Witt C, Pach D, Brinkhaus B, et al Safety of

Scand 2012;91:281–6 Chapter 14 Management of idiopathic chronic pelvic pain William D Schlaff 14 Introduction Chronic pelvic pain is generally defined as pain of the pelvis, lower abdomen, and/ or back and upper leg lasting for six months or more The scope of chronic pelvic pain in the USA is daunting Up to 20% of women of reproductive age will complain of chronic pelvic pain of greater than one year in duration, and a very large number of gynecological visits to healthcare providers are related to pelvic pain [1] Depending on the gynecological practice, 30% or more laparoscopies and perhaps 15–20% of hysterectomies are performed for treatment of chronic pelvic pain [2] The fact that many of these treatments are ineffective in reducing pain reflects the incomplete understanding of the basis of pain and the treatment methods that are most effective in different circumstances A patient’s description of chronic pelvic pain is often vague and inconsistent, which reflects the numerous factors that can contribute to the symptoms It is regrettable that the diagnosis of chronic pelvic pain is often approached as a specific entity without distinguishing between the many symptoms that are typically associated with specific etiologies This observation reinforces the critical importance of a comprehensive and thoughtful history in evaluating patients with chronic pelvic pain It is far too common for patients to be characterized based on what is often an anatomical or visual manifestation having little or even nothing to with the symptoms experienced by the patient [3] It should be appreciated that chronic pelvic pain associated with minimal objective endometriosis may in fact be no different from chronic pelvic pain in women who have a visually normal pelvis The goal of this chapter is to address pain that is not specifically related to endometriosis Chronic Pelvic Pain, ed William Ledger, William D Schlaff and Thierry G Vancaillie Published by Cambridge University Press © Cambridge University Press 2015 148 Chapter 14: Idiopathic chronic pelvic pain 149 Taking a focused history The key to identifying the best approach to evaluating a woman with chronic pelvic pain starts with a careful and thoughtful history addressing the many symptoms that can be involved History and physical examination have been covered in earlier chapters, although in this chapter it is appropriate to point out factors that may have significant bearing on whether a patient’s pain is likely to be caused by endometriosis or not Key components of the history should aim at differentiating the specific basis of the various etiologies of the pain, which certainly may include endometriosis but may come from a variety of other sources The overlap between endometriosis-related pain and interstitial cystitis is well known and is discussed in Chapter 10 Similarly, there is a significant overlap between endometriosis and irritable bowel syndrome Other causes of pain from a gastrointestinal source are generally well known and can include inflammatory bowel disease among others Musculoskeletal or pelvic floor irritation is commonly the source of pain, and it is important to try to tease out this diagnosis As clinicians develop a broader appreciation and understanding of these problems, they also begin to appreciate the limitations in diagnosing what may be the most common source of chronic pelvic pain – neuropathic pain The classic history and physical examination in patients with endometriosis are discussed in previous chapters and will not be emphasized in great detail here Patients with endometriosis typically present initially with symptoms of dysmenorrhea associated with their menstrual periods Depending on the location and extent of lesions, they may have direct anatomically related complaints, such as dyspareunia caused by painful uterosacral nodules Pain may gradually progress to become notable at times other than during menses and is typically described as vague and achy when this occurs Patients who have moderate to severe endometriosis, often with adhesions and possible endometriomas, will frequently describe this evolution of symptoms The clinician should have a high suspicion that a patient’s symptoms are unrelated to endometriosis in those cases where there is minimal or very transient response to effective treatments, even when endometriosis has been documented by previous surgical evaluation These patients typically have American Society for Reproductive Medicine (ASRM) stage I (minimal) disease, which leads to a very plausible notion that patients with stage I disease may practically be equivalent to patients who have a normal pelvis The concepts discussed above are illustrated by two seminal papers, one by Chris Sutton and colleagues [4] and a second by Frank Ling [5] The first study involved performing laparoscopy in women suspected of having endometriosis and prospectively randomizing them to aggressive surgical destruction of endometriotic lesions or simply recording the findings without surgical intervention The patients were followed in a double-blind fashion postoperatively; the physician evaluating postoperative pain was unaware of the patient’s group assignment The investigators found no significant difference in response at three months, although the response rate at six months was higher in the treated group Perhaps most interestingly, the likelihood of response was correlated with the extent of disease, contrary to what is often suggested Those with the most endometriosis had the highest rate of responding, and those with the least (ASRM stage I) responded in a manner similar to patients treated with a placebo for endometriosis (i.e 40%) [4] Ling randomized 100 women suspected of having endometriosis to three months of treatment with a gonadotropin-releasing hormone or placebo prior to definitive laparoscopy Laparoscopy 150 Chapter 14: Idiopathic chronic pelvic pain confirmed that most of the patients did indeed have endometriosis, and that the majority of women with endometriosis and treated with the analog had responded, compared with less response in the placebo group [5] Interestingly, the small group who had no endometriosis at laparoscopy (i.e normal appearing pelvis) responded to analog and placebo in similar proportions Previous chapters have described typical findings in those women with bladder and gastrointestinal problems Those with musculoskeletal or pelvic floor abnormalities will usually describe pain with movement and/or radicular pain They may also have back pain or pain with sitting, twisting, or exercise It is often difficult to identify the precipitating factor for musculoskeletal pain, but the clinician should nevertheless strongly consider a musculoskeletal etiology if suggested by the symptom complex Chronic neuropathic pain is characterized by chronic and often non-specific symptoms that have not been diagnosed by focusing on the histories as described above, or those with early stages of endometriosis who not respond to commonly effective treatments Acute pain transmission is often described as adaptive; it is valuable for a woman feeling a hot surface to remove her hand in order to avoid being burned In contrast, chronic pain neuropathy is a maladaptive pain response in which there is chronic activation of afferent pain fibers without any acute stimulus These patients typically respond to annoying but not painful stimuli with dramatic symptoms far out of proportion to the stimulus itself A number of theories of the etiology of this type of pain have been suggested, including viral infections such as herpes, but at present there is no clearly accepted explanation There are a number of hints that should lead the clinician to suspect that the patient has chronic neuropathic pain rather than endometriosis-related pain For example, patients with chronic neuropathic pain will often describe pain that cannot be easily related to a physiological provocation (e.g menses) or an anatomical distribution that is easily explained In contrast to those with endometriosis-related pain, women with neuropathic pelvic pain typically describe little or no relationship between their menstrual period and their discomfort The pain may be described as evanescent, lasting only seconds to a minute, or, at the opposite extreme, as constantly present Surgical and medical therapy will often provide transient or no relief at all In many cases, patients will describe some initial benefit with treatment but will find less and less benefit over time or with retreatment In the USA, these patients often describe a history of multiple surgical procedures for treatment of endometriosis with each one providing less benefit than the one before until there is no benefit at all Scrutiny of the operative reports will often reveal minimal endometriosis (or “possible endometriosis”) at the initial laparoscopy, treated with some type of destructive therapy Pain relief is usually limited, perhaps a year or less, and a subsequent laparoscopy may show similar peritoneal findings with new adhesion, which may well be related to the initial surgical treatment Pain relief is typically of shorter duration following a second surgery, and subsequent surgeries often show no or minimal new findings, which may, in fact, be related to the surgeries themselves These patients often describe associated symptoms such as abdominal or vaginal pain, and vaginismus resulting in dyspareunia They may have additional symptoms often diagnosed as fibromyalgia and/or chronic fatigue syndrome As the symptoms become more severe, the patient is commonly unable to pursue her usual activities of daily life Chapter 14: Idiopathic chronic pelvic pain 151 Physical examination Typical physical findings of patients with endometriosis are described in previous chapters When specific physical findings are present they will often be in the distribution of the lesion(s) The best examples would be painful uterosacral nodules and/or endometrioma, or pain with attempting to move pelvic organs fixed by inflammatory endometriotic adhesions It could be presumed that the latter discomfort would be associated with putting stretch on inflamed tissues The clinician may find hints that pain is from a musculoskeletal source simply by observing the patient’s posture Musculoskeletal pain will often be manifest by splinting to one side, or by reduced range of motion Asking the patient to twist or stretch from a fixed posture may also be helpful A screening neurological examination is occasionally helpful in identifying patients with some type of radicular pain or neuropathy In contrast to patients with endometriosis-related pain, women with neuropathic pain often have a physical response significantly out of proportion to the anticipated response from the examination Such patients often have tremendous discomfort simply with digital insertion of an examining finger in the vagina, with placement of a vaginal speculum, or when a pap smear is obtained Palpation of the abdominal wall will often produce significant tenderness out of proportion to physical findings Isolated trigger points, specific areas that are particularly tender to palpation with an instrument such as a cotton swab (Q-tip) are common Isolating the source of the pain to the abdominal wall rather than the pelvis can often be accomplished by examining the patient before and after straight leg raising If specific areas of tenderness are identified on abdominal examination and are still tender (or even more tender) when the patient raises her legs off the table, the clinician can inform the patient that the pain is arising from the abdominal wall rather than the pelvis The apparently excessive response to minimally uncomfortable stimuli is often felt to represent a “ramping up” of painful signals from the spinal cord to the thalamus, which is often seen in chronic pain syndromes The clinician should presume that the woman who has chronic and prolonged pain as well as hyper-responsiveness to examination, as described above, is likely suffering from neuropathic pain rather than directly from endometriosis-related pain Management Further diagnostic or treatment steps may be indicated once the clinician has completed the history and physical examination as described Laparoscopy is usually recommended for those with a specific history or physical findings suggestive of endometriosis Depending on the findings, diagnostic imaging (usually ultrasound or MRI) may be considered prior to surgery In the USA, many women without specific findings are started empirically on a course of oral contraceptive pills, and those who have inadequate or no response almost always undergo laparoscopy It is possible that more careful attention to the associated findings as described in this chapter could help some women to avoid surgery that is destined to provide little benefit to them If the clinician believes the pain is arising from a specific musculoskeletal source, approaches such as stretching, physical therapy, yoga, and acupuncture may prove helpful Treatment with anti-inflammatory medications may enhance response to these physical approaches Myofascial pain appears to be a significant component in up to 152 Chapter 14: Idiopathic chronic pelvic pain 75% of patients who report chronic pelvic pain [6] A number of possible causes of myofascial pain have been suggested, including chronic irritation from posture or musculoskeletal irritation or injury It is apparent that psychosocial stress can exacerbate myofascial pain by increasing muscle tension A specific “pelvic pain posture” has been described characterized by notably rounded shoulders with the head directed forward, exaggerated lumbar lordosis, forward tilt of the pelvis, hyperextended knees, and a line of gravity displaced interiorly in the lower extremities and pelvis It has been suggested that this posture may produce a shortening or increased tone of the iliopsoas, piriformis, and obturator muscles and sacroiliac joint strain The chronic irritation may lead to hyperirritability of nerve fibers and may respond to rest, heat, non-steroidal anti-inflammatory drugs or muscle relaxants Heat, massage, or icing the area can sometimes reduce myofascial pain Physical therapy with a specific focus on posture and/or stretching has been recommended and can be helpful Whether from these or other etiologies, abdominal wall trigger points are commonly seen in women with a myofascial component These trigger points can cause referred pain when compressed on physical examination, usually with a Q-tip If trigger points not respond to the approaches described, local injections may be performed directly into the area of the identified trigger point A number of different anesthetic formulations have been described for trigger point injections These include 1% lidocaine with epinephrine, which may be mixed in a 1:1 ratio with 0.25% bupivacaine Some physicians add corticosteroids to the formulation Typically the trigger points are identified with Q-tip palpation and marked on the abdomen A narrow (usually 26–30 gauge) needle is used to inject 2–3 ml of this solution into each trigger point Injections are generally repeated weekly initially and less frequently as improvement occurs Response rates have been reported between 50 and 90% following several months of treatment [7] Irritable bowel syndrome typically is characterized by greater than three stools per day or less than three per week Other symptoms include abnormal stool form described as lumpy kind of watery, kind of hard; abnormal stool passage with straining, urgency, or incomplete evacuation; bloating; or other non-specific gastointestinal symptoms [8] Celiac sprue should be excluded The diagnosis of irritable bowel syndrome is usually entertained based on history and the absence of any specific gasgtrointestinal etiology Primary treatments for irritable bowel syndrome start with the cessation of smoking Easy approaches include avoiding caffeine, carbonated beverages, lactose, sorbitol, and chewing gum Antispasmodics such as dicyclomine or selective serotonin reuptake inhibitors such as fluoxetine may be considered Non-specific treatments of constipation and/or diarrhea may also be helpful [9] The largest group of women referred to chronic pain specialists in the USA contains those who have not had a satisfactory response to previous medical or surgical therapy – that is, women with idiopathic chronic pelvic pain Treatment of these patients is usually approached empirically using some or all of the approaches described above The next steps in treating these patients include the following Medical treatment Pharmacological treatments are often recommended, particularly in association with a multidisciplinary approach including some of the other therapies described Medications are typically prescribed on a regular as opposed to “as needed” (prn) dosing Chapter 14: Idiopathic chronic pelvic pain 153 regimen Non-steroidal anti-inflammatory drugs are most widely used, sometimes with anxiolytics when there is a significant component of anxiety Tricyclic antidepressants such as amitriptyline or imipramine can be beneficial in doses much lower than those used in treatment of depression A typical starting dose of 25 mg orally at night for one week can be increased by 25 mg weekly to a maximum dose of 100 mg at night Neuromodulators such as gabapentin have been used with significant benefit Typical dosages of gabapentin are 300 mg daily increasing over one or more weeks to a total dose of 300 mg three times a day Maintenance dose can be as much as 2700 to 3000 mg daily in three divided doses The clinician should not prescribe more than 1200 mg in a single dose More recently, oral pregabalin has been used in the same setting at an initial dose of 50 mg per day gradually increasing to a maximum dose of 100 mg three times a day (300 mg/day total) The selective serotonin reuptake inhibitors, including sertraline up to 50 to 150 mg every morning and fluoxetine up to 20 to 40 mg every morning, have been effective as have the selective serotonin–norepinephrine reuptake inhibitors venalaxine (up to maximum of 225 mg/day) or duloxetine (divided doses up to maximum of 60 mg/day) Physical therapy Physical therapy is often recommended and can be beneficial in pain control The goal is generally to reduce pelvic muscle tone and decrease patient anxiety by direct treatment of muscle spasm and introduction of home exercise to help with pain relief and reduce stress Electrotherapy, biofeedback, vaginal dilators, and pelvic floor exercises have been recommended Physical therapists generally try to mobilize the nerves or muscles believed to be under tension, often with connective tissue manipulation and myofascial release While this approach has been shown to be successful, there are few controlled data to help to identify and specify the most effective approaches Acupuncture Acupuncture is often used successfully to treat primarily dysmenorrhea, although data about its success in non-menstrual chronic pelvic pain are not as clear The mechanism is not established, but many patients derive benefit from this approach Similarly, sacral nerve electrical stimulation via implantable devices has been used in very difficult chronic pelvic pain with varying degrees of success These approaches show promise, although the primary indications and best treatment plans are not well established Behavioral modification and psychotherapy Previous chapters have reviewed a number of associated social and psychological contributors to pelvic pain along with their possible treatments and will not be further discussed in this chapter Conclusions Chronic pelvic pain is often attributed to physical findings or diagnoses such as endometriosis even when the findings not correlate well with the nature of the symptoms Clinicians must be sensitive to pain from other sources, including the gastrointestinal tract and musculoskeletal system It is important to strongly consider a chronic neuropathic origin of the pain, particularly when the symptoms are not very suggestive of a 154 Chapter 14: Idiopathic chronic pelvic pain specific etiology or when medical or surgical treatment aimed at endometriosis provides little or no benefit Extensive or extirpative surgery is not advised in such women Rather, a number of alternative approaches to treatment should be considered as described in this chapter Finally, it is important to avoid the too-simplistic pitfall of attributing chronic neuropathic pain to minimal endometriosis when the patient does not respond adequately to the usually effective treatments for endometriosis References endometriosis Pelvic Pain Study Group Obstet Gynecol 1999;93:51–8 Mathias SD, Kuppermann M, Liberman RF, Lipschutz RC,
