Systematic Review of Therapies for Noncyclic Chronic Pelvic Pain in Women

Patient Perspectives on the Psychosocial Impact of Chronic Pelvic Pain and Implications for Integrated Behavioral Care Approaches

Chronic pelvic pain (CPP) is a medically complex, multifaceted gynecological condition associated with psychological comorbidities and sexual trauma among women. Low rates of positive treatment outcomes underscore the need to better understand complex relationships between CPP, trauma exposure, and the psychosocial context of patients' lives. We conducted a secondary analysis of English and Spanish qualitative interviews with female-identity patients (N = 48) about CPP's impact on psychosocial well-being. Interviews were coded and analyzed in accordance with reflexive thematic analysis. We generated 4 themes regarding CPP and psychosocial well-being: navigating pain-filled relationships, multiple burdens of mental health challenges and marginalization, sexual trauma exposure embedded in illness experience, and harnessing hope in healing and dealing with CPP. We used insights from these findings to generate a list of treatment recommendations for trauma-informed, CPP-specific integrated care. Patients described the importance of social support and how psychological comorbidities and trauma exposure contributed to CPP's psychosocial toll. Findings provide insight into the burden of CPP-related minority stress and the role of hope on patients' well-being. Patients with CPP endorse the integration of psychosocial support into their CPP treatment plans. The authors encourage the incorporation of behavioral health providers into integrated care teams to deliver trauma-informed, culturally responsive methods for engaging patients with CPP in psychosocial interventions addressing multiple domains of well-being.

Effectiveness of nonpharmacological conservative therapies for chronic pelvic pain in women: a systematic review and meta-analysis

OBJECTIVE

To evaluate the effectiveness of nonpharmacological conservative therapies for women with CPP.

DATA SOURCES

A systematic search of electronic databases (Amed, CINAHL, PsycINFO, SportDiscuss, Medline, PubMed, Embase, and Cochrane Central Register of Controlled Trials) was performed in January 2023, and updated in December 2023.

STUDY ELIGIBILITY CRITERIA

Randomized controlled trials comparing a nonpharmacological conservative therapy to inert (eg, placebo, usual care) or nonconservative (eg, surgical, pharmacological) treatment were included. Conservative therapies of interest to this review were: multimodal physical therapy, predominantly psychological approaches, acupuncture, and other tissue-based monotherapies (eg, electrophysical agents, manual stretching).

STUDY APPRAISAL AND SYNTHESIS METHODS

All study data were aggregated, and analyses of the included studies were performed. Effects on pain; sexual measures; psychological and physical function; health-related quality of life; symptom severity/bother; pelvic floor muscle function and morphometry; perceived improvement; and adverse events were analyzed. Meta-analyses (random effects model) were conducted using postintervention scores for data that included similar interventions and outcomes. Standardized mean differences were calculated. A narrative summary of findings that could not be included in the meta-analysis is provided. The quality of the evidence was assessed with the Physiotherapy Evidence Database scale and the certainty of evidence with Grading of Recommendations, Assessment, Development, and Evaluations criteria.

RESULTS

Of 5776 retrieved studies, 38 randomized controlled trials including 2168 women (mean age 35.1±8.6) were included. Meta-analyses revealed that multimodal physical therapy resulted in lower pain intensity compared to inert or nonconservative treatments in both the short (standardized mean difference -1.69, 95% confidence interval -2.54, -0.85; high certainty) and intermediate-terms (standardized mean difference -1.82, 95% confidence interval -3.13, -0.52; moderate certainty), while predominantly psychological approaches resulted in no difference in pain intensity (standardized mean difference -0.18, 95% confidence interval -0.56, 0.20; moderate certainty) and a slight difference in sexual function (standardized mean difference -0.28, 95% confidence interval -0.52, -0.04; moderate certainty). The level of evidence regarding the meta-analysis of the effects of acupuncture on pain intensity (standardized mean difference 1.08, 95% confidence interval -1.38, 3.54, nonstatistically significant results in favor of control treatment) precluded any statement of certainty. A limited number of trials investigated individual tissue-based monotherapies, providing a restricted body of evidence.

CONCLUSION

This systematic review with meta-analysis revealed that multimodal physical therapy is effective in women with chronic pelvic pain with a high certainty of evidence.

Dorsal root ganglion stimulation for the treatment of chronic pelvic pain: A systematic review

BACKGROUND

Chronic pelvic pain (CPP) is a difficult condition to treat. Due to complex pelvic innervation, dorsal column spinal cord stimulation (SCS) has not been shown to produce the same effect as dorsal root ganglion stimulation (DRGS) given emerging evidence suggesting that applying DRGS may result in favorable outcomes for individuals with CPP. The aim of this systematic review is to investigate the clinical use and effectiveness of DRGS for patients with CPP.

MATERIALS AND METHODS

A systematic review of clinical studies demonstrating the use of DRGS for CPP. Searches were conducted using four electronic databases (PubMed, EMBASE, CINAHL, and Web of Science) across August and September 2022.

RESULTS

A total of nine studies comprising 65 total patients with variable pelvic pain etiologies met the inclusion criteria. The majority of subjects implanted with DRGS reported >50% mean pain reduction at variable times of follow-up. Secondary outcomes reported throughout studies including quality of life (QOL) and pain medication consumption were reported to be significantly improved.

CONCLUSIONS

Dorsal root ganglion stimulation for CPP continues to lack supportive evidence from well-designed, high-quality studies and recommendations from consensus committee experts. However, we present consistent evidence from level IV studies showing success with the use of DRGS for CPP in reducing pain symptoms along with reports of improved QOL through periods as short as 2 months to as long as 3 years. Because the available studies at this time are of low quality with a high risk of bias, we strongly recommend the facilitation of high-quality studies with larger sample sizes in order to better ascertain the utility of DRGS for this specific patient population. At the same time, from a clinical perspective, it may be reasonable and appropriate to evaluate patients for DRGS candidacy on a case-by-case basis, especially those patients who report CPP symptoms that are refractory to noninterventional measures and who may not be ideal candidates for other forms of neuromodulation.

Beliefs and Narratives Associated with the Treatment of Chronic Pelvic Pain in Women

STUDY OBJECTIVE

Female patients with chronic pelvic pain (CPP) face complicated healthcare journeys, but narrative perspectives on CPP treatment are lacking.

DESIGN

We collected data in English and Spanish from discussion groups and individual interviews with stakeholders around female CPP.

SETTING

A tertiary care center for gynecologic care.

PATIENTS

Patients with CPP who self-identified as women/female, community healthcare workers, and providers who care for women with CPP.

INTERVENTIONS

We conducted discussion groups with all 3 types of stakeholders and individual interviews with female patients who have CPP.

MEASUREMENTS AND MAIN RESULTS

Patient participants completed condition specific validated questionnaires. De-identified transcripts were coded with NVivo software. We contrasted patient characteristics and codes between patients with CPP who did and did not report opioid use in the last 90 days. The mean pain score of patient participants was 6/10 ± 2/10, and 14 of 47 (28%) reported recent opioid use, without significant differences between patients with and without recent opioid use. Thematic saturation was achieved. Five main themes emerged: the debilitating nature of CPP, emotional impacts of CPP, challenges in CPP healthcare interactions, treatment for CPP, and the value of not feeling alone. Common threads voiced by stakeholders included difficulty discussing chronic pain with others, a sense of inertia in treatment, interest in alternative and less invasive treatments before more involved treatments, and the need for individualized, stepwise, integrated treatment plans. Participants agreed that opioids should be used when other treatments fail, but women recently using opioids voiced fewer concerns about addiction and positive experiences with opioid efficacy.

CONCLUSIONS

These findings among female patients with CPP and also among community healthcare workers and providers advocate for a move toward patient-centered care, particularly the acknowledgment that every woman experiences pain in a singular way. Furthermore, stakeholders voice a deep need for development of individualized treatment plans.

Non-pharmacological therapies for treating chronic pelvic pain in women: A review

Chronic pelvic pain (CPP) is an intricate condition with multiple etiologies that lead to indefinite pain mechanisms. Physicians and researchers are challenged in its treatment, and the combined therapy of pharmacologic and non-pharmacologic treatment has been recognized as a multidisciplinary approach cited by guidelines and adopted in clinical practice. As an alternative therapy for CPP, non-pharmacologic therapies benefit patients and deserve further study. This study reviews the literature published from January 1991 to April 2022 on non-pharmacologic therapies for CPP in adult women. Based on a survey, this review found that the most commonly used non-pharmacological therapies for CPP include pelvic floor physical therapy, psychotherapy, acupuncture, neuromodulation, and dietary therapy. By evaluating the efficacy and safety of each therapy, this study concluded that non-pharmacological therapies should be included in the initial treatment plan because of their high degree of safety and low rate of side effects. To fill the lack of data on non-pharmacologic therapies for CPP, this study provides evidence that may guide treatment and pain management.

Transvaginal Photobiomodulation for the Treatment of Chronic Pelvic Pain: A Pilot Study

Background: Chronic pelvic pain (CPP) is a common and debilitating condition that affects millions of U.S. women. Most treatments are ineffective and innovative new therapies are desperately needed. Large, controlled studies show that photobiomodulation (PBM) can reduce pain in patients with other chronic pain conditions, such as low back pain, neck pain, and fibromyalgia. The objective of this pilot study was to determine if transvaginal PBM (TV-PBM) can reduce pain in women with CPP. Methods: We conducted a before and after, observational, pilot study. Patients completed the Short Form-McGill Pain Questionnaire (SF-MPQ) at baseline, 1 week, 3 months, and 6 months after nine treatments of TV-PBM. Clinicians completed the Clinical Global Impression Scale (CGI) assessing patient illness severity at the same time. Wilcoxon rank-sum t-tests and effect size using Cohen's d coefficient (low effect size if d < 0.2, medium if 0.2 < d > 8, and high if d > 0.8) was used to measure degree of pain improvement, which was also considered clinically significant if pain reduction was >30%. Results: Thirteen women completed 9 treatments, and 10 women were successfully followed to 6 months. At baseline, the mean SF-MPQ score was 19.7 (standard deviation [SD] ± 5.9). Compared with baseline, 60% improved; the mean SF-MPQ score decreased to 10.0 (SD ±7.5, p = 0.004, d = 1.6) at 1 week after treatment, to 9.7 (SD ±7.9, p = 0.005, d = 1.7) at 3 months, and 8.2 (SD ±8.1, p = 0.002, d = 1.9) at 6 months. Conclusion: Transvaginal PBM provided significant and sustained pain relief to women with CPP up to 6 months. Further controlled studies are needed to confirm these findings, however, in this initial pilot, TV-PBM shows promise.

Chronic pelvic pain – pain catastrophizing, pelvic pain and quality of life

Background and aims

Chronic pelvic pain (CPP) impacts significantly on the lives of women. Negative coping responses such as pain catastrophizing are thought to be significant in predicting both pain severity and outcome. The combined effect of the individual’s response to pain and its severity on their quality of life (QoL) has not been well studied in women with CPP. Aims were to determine the prevalence of pain catastrophizing in women with CPP and to examine the associations between pain catastrophizing and levels of dysmenorrhea, non-cyclical pelvic pain, dyspareunia, dysuria, dyschezia and QoL.

Methods

A cross-sectional study including women aged 18–50 years, referred to a tertiary gynecology outpatients department at an Australian women’s hospital in 2015. Participants completed questionnaires including: pain catastrophizing scale (PCS); pelvic pain levels in the prior 3 months; and the World Health Organisation Quality of life – Bref Questionnaire (WHOQoL-Bref). Statistical analysis was performed using STATA (StataCorp, USA Version13).

Results

Participants (n = 115) had a median age of 29.0 [interquartile range (IQR): 23.0–38.0] years. The Pain catastrophizing score revealed that 60/113 [95% confidence interval (CI): 48.6, 71.2] of participants had a clinically relevant total score ≥30. There were statistically significant positive correlations between pain catastrophizing scores and pelvic pain levels in all five pain categories studied, dysmenorrhea (ρ = 0.37, p = 0.0001), non-cyclical pelvic pain (ρ = 0.46, p<0.0001), dyspareunia (ρ = 0.32, p = 0.0008), dysuria (ρ = 0.32, p = 0.0005) and dyschezia (ρ = 0.38, p = 0.0012). Participants who reported maximal pain levels (5/5) had significantly higher median pain catastrophizing scores when compared to those who reported no pain (0/5) in all categories. Overall QoL was considered as “good” in 71/113 (95% CI: 60.1, 81.0) participants and “poor” in 42/113 (95% CI: 32.0, 53.0) participants. Comparison to Australian female norms revealed significantly lower QoL scores in the physical domain, across all ages, and in psychological domain for those aged <30 and 30–40 years. There was a significant association between increased catastrophizing scores and reduced odds of good QoL. An increase in PCS by one point is associated with a 6.3% decrease in the odds of good QoL [odds ratio (OR) per one-point increase: 0.94 (95% CI: 0.89, 0.98), p = 0.008].

Conclusions

Pain catastrophizing is prevalent at clinically relevant levels in women with CPP across all domains. It is associated with higher pain levels and decreased QoL.

Implications

There is potential for further studies to investigate the predictive nature of pain catastrophizing and management targeting catastrophizing to improve outcomes in women with CPP.

Physiotherapy management of patients with chronic pelvic pain (CPP): A systematic review

INTRODUCTION

Chronic pelvic pain (CPP) is a common pain condition. However, treatment remains challenging. Musculoskeletal findings are frequent; therefore physiotherapy might be helpful. The purpose of this review was to evaluate the current evidence on physiotherapy in patients with CPP (PROSPERO registration number CRD42016037516).

METHODS

Six databases were searched and additional hand searches were performed. Two reviewers independently conducted the database search and selected studies using a two-step approach. The methodological quality was assessed applying the Critical Review Form - Quantitative Studies.

RESULTS

A total of eight studies were included. Trigger point therapy was examined in four studies; two of which were randomized controlled trials. All studies indicate a significant change in pain measurement. The other four studies evaluated the effect of biofeedback, Thiele massage, Mensendieck somatocognitive therapy and aerobic exercises, whereas the last two were tested in controlled trials. All studies showed significant improvements in pain assessment.

CONCLUSIONS

The evidence currently available is sparse with methodological flaws, making it difficult to recommend a specific physiotherapy option. There is an urgent need for high-quality randomized controlled trials to identify the most effective physiotherapy management strategy for patients with CPP.

Concomitant female genital tuberculosis and endometriosis

AIMS

To demonstrate an association between female genital tuberculosis (FGTB) and endometriosis.

METHODS

A total of 16 women who underwent laparoscopy (12 cases) or laparotomy (4 cases) and were found to have female genital tuberculosis and endometriosis were enrolled in this retrospective study.

RESULTS

The mean age and parity were 28.2 years and 0.2, respectively. Past history of tuberculosis was present in 75% of the women (pulmonary in 50%). Menstrual dysfunction (especially oligomenorrhoea and dysmenorrhoea), constitutional symptoms, infertility, abdominal pain and lump were the main complaints. Diagnosis of FGTB was made by positive acid-fast bacilli (AFB) on microscopy, culture of endometrial aspirate, positive polymerase chain reaction (PCR), histopathological finding of epitheliod granuloma or findings of TB on laparoscopy or laparotomy. Diagnosis of endometriosis was made by laparoscopy or laparotomy. Pelvic adhesions were seen in all women, whereas frozen pelvis was seen in 7 (43.7%) women. Surgery was performed, which was laparoscopic adhesiolysis in 12 (75%), drainage of endometrioma in 12 (75%), cystectomy in 8 (50%), and total abdominal hysterectomy with bilateral salpingo-oophorectomy in 4 (25%) cases. With more then one type of (surgery in many cases).

DISCUSSION

Female genital tuberculosis and endometriosis may have similar manifestations and can co-exist.

Sensitivity and specificity of clinical findings for the diagnosis of pelvic congestion syndrome in women with chronic pelvic pain

Background

Pelvic congestion syndrome is among the causes of pelvic pain. One of the diagnostic tools is pelvic venography using Beard’s criteria, which are 91% sensitive and 80% specific for this syndrome.

Objective

To assess the diagnostic performance of the clinical findings in women diagnosed with pelvic congestion syndrome coming to a Level III institution.

Methods

Descriptive retrospective study in women with chronic pelvic pain taken to transuterine pelvic venography at the Advanced Gynecological Laparoscopy and Pelvic Pain Unit of Clinica Comfamiliar, between August 2008 and December 2011, analyzing social, demographic, and clinical variables.

Results

A total of 132 patients with a mean age of 33.9 years. Dysmenorrhea, ovarian points, and vulvar varices have a sensitivity greater than 80%, and the presence of leukorrhea, vaginal mass sensation, the finding of an abdominal mass, abdominal trigger points, and positive pinprick test have a specificity greater than 80% when compared with venography.

Conclusion

This study may be considered as the first to evaluate the diagnostic performance of the clinical findings associated with pelvic congestion syndrome in a sample of the Colombian population. In the future, these findings may be used to create a clinical score for the diagnosis of this condition.

Complementary and Alternative Medicine in the Treatment of Chronic Pelvic Pain in Women: What Is the Evidence?

Chronic pelvic pain (CPP) is defined as pain of at least 6 months' duration that occurs in the lower abdomen or below the umbilicus and has resulted in functional or psychological disability or required intervention and treatment. Therapeutic interventions center around the treatment of CPP as a diagnosis in and of itself, and treatment of specific disorders that may be related to CPP. A multidisciplinary approach for diagnosis and treatment seems to be most effective for symptomatic relief. This paper reviews the evidence for such interventions as psychological treatments including the use of complementary and alternative medicine techniques for CPP in women. Unfortunately, finding the best evidence in this setting is difficult as only very few randomized controlled trials are available. A combination of treatments is usually required over time for the treatment of refractory CPP. The multifactorial nature of CPP needs to be discussed with the patient and a good rapport as well as a partnership needs to be developed to plan a management program with regular followup. Promotion of a multidisciplinary approach which includes complementary and alternative medicine techniques in managing CPP in women seems to yield the best results.

A surveillance system to assess the need for updating systematic reviews

BACKGROUND

Systematic reviews (SRs) can become outdated as new evidence emerges over time. Organizations that produce SRs need a surveillance method to determine when reviews are likely to require updating. This report describes the development and initial results of a surveillance system to assess SRs produced by the Agency for Healthcare Research and Quality (AHRQ) Evidence-based Practice Center (EPC) Program.

METHODS

Twenty-four SRs were assessed using existing methods that incorporate limited literature searches, expert opinion, and quantitative methods for the presence of signals triggering the need for updating. The system was designed to begin surveillance six months after the release of the original review, and then ceforth every six months for any review not classified as being a high priority for updating. The outcome of each round of surveillance was a classification of the SR as being low, medium or high priority for updating.

RESULTS

Twenty-four SRs underwent surveillance at least once, and ten underwent surveillance a second time during the 18 months of the program. Two SRs were classified as high, five as medium, and 17 as low priority for updating. The time lapse between the searches conducted for the original reports and the updated searches (search time lapse - STL) ranged from 11 months to 62 months: The STL for the high priority reports were 29 months and 54 months; those for medium priority reports ranged from 19 to 62 months; and those for low priority reports ranged from 11 to 33 months. Neither the STL nor the number of new relevant articles was perfectly associated with a signal for updating. Challenges of implementing the surveillance system included determining what constituted the actual conclusions of an SR that required assessing; and sometimes poor response rates of experts.

CONCLUSION

In this system of regular surveillance of 24 systematic reviews on a variety of clinical interventions produced by a leading organization, about 70% of reviews were determined to have a low priority for updating. Evidence suggests that the time period for surveillance is yearly rather than the six months used in this project.
