A Comprehensive Treatment Protocol for Endometriosis Patients Decreases Pain and Improves Function

Purpose

The purpose of this paper is to evaluate the efficacy of a multimodal, outpatient neuromuscular protocol in treating remaining sensitization and myofascial pain in endometriosis patients post-surgical excision.

Patients and Methods

A retrospective longitudinal study was conducted for women aged 22 to 78 with a history of surgically excised endometriosis. 60 women with an average duration of pain of 8.63 ± 7.65 years underwent a treatment protocol consisting of ultrasound guided trigger point injections, peripheral nerve blocks, and pelvic floor physical therapy for 6 weeks. Concomitant cognitive behavioral therapy once weekly for a total of 12 weeks was also undertaken. Pain intensity and pelvic functionality were assessed at new patient consults and 3-month follow ups using Visual Analogue Scale (VAS) and Functional Pelvic Pain Scale (FPPS).

Results

At new patient consults, average VAS and FPPS were 7.45 ± 2.11 (CI 6.92-7.98) and 14.35 ± 6.62 (CI 12.68 -16.02), respectively. At 3-month follow ups, average VAS and FPPS decreased to 4.12 ± 2.44 (CI 3.50-4.73; p < 0.001) and 10.3 ± 6.55 (CI 8.64-11.96; p < 0.001), respectively. Among FPPS categories, sleeping, intercourse, and working showed the highest statistical significance.

Conclusion

Data suggests the multimodal protocol was effective in treating the remaining underlying sensitization and myofascial pain seen in Endometriosis patients post-surgical excision, particularly in decreasing pain and improving function during work and intercourse.

What's out There? A Systematic Review of the Efficacy and Availability of Targeted Treatments for Central Sensitisation in Women with Endometriosis

OBJECTIVES

Central sensitisation contributes to patient variability when treating pain in endometriosis. Targeting this process may alleviate hyperalgesia and allodynia in women refractory to current treatments. Thus far, there has been no review of targeted treatments for central sensitisation in women with endometriosis. Therefore, this review aims to identify and summarise the findings of studies regarding the availability and efficacy of targeted treatments for central sensitisation in women with endometriosis.

METHODS

A systematic review was conducted searching MEDLINE, Embase and CINAHL. Inclusion criteria: primary research articles, women with endometriosis and central sensitisation features, and description of treatments for central sensitisation, or its effects on hyperalgesia and allodynia. Exclusion criteria: review articles, letters to the editor, commentaries, editorials, protocols, or women with endometriosis infiltrating nerves. Risk of bias analysis was conducted. Data was reviewed and summarised by treatment method.

RESULTS

Eight studies met inclusion criteria, demonstrating limited research in this area. Four treatment options were addressed: surgical approaches, nerve stimulation approaches, injection-based therapies, and hormonal therapies. Surgery and nerve stimulation appear the most promising treatments for central sensitisation. Injections have limited and mixed evidence of efficacy. Limited evidence suggests hormonal therapies may be ineffective.

DISCUSSION

Given the lack of evidence for any treatment, all require further research to determine treatment efficacy before options will be available clinically. There is a clear need for consistency in defining and identifying central sensitisation in study populations. This review identifies areas of interest, particularly surgery and nerve stimulation, from which future research must stem.

A physiatrist's understanding and application of the current literature on chronic pelvic pain: a narrative review

Understanding the complex, multifactorial nature of chronic pelvic pain can help physicians determine the pain's etiology and thus refer specialists to include in the multidisciplinary treatment required.

Chronic pelvic pain (CPP) is a highly prevalent condition which is underdiagnosed and poorly understood. The purpose of this review is to outline the various aspects of the nature of CPP, including its etiologies, clinical presentation, and nonoperative treatment options. For data collection, a PubMed search was conducted using indexing terms such as chronic pelvic pain and pelvic pain. Literature reviews and studies focusing on etiologies, clinical presentation, and/or the diagnosis of CPP were compiled for review by a team of 3 physiatrists. Studies investigating conservative treatments, medications, and interventional procedures for CPP and related conditions with comparable etiologies were also included. Of the 502 articles retrieved, 116 were deemed suitable by the team for this study. Although CPP is a complex, multifaceted condition, a particular susceptibility to nociceptive stimuli was demonstrated as an underlying theme in its evolution. There are many treatment options currently used; however, more robust evidence, such as randomized controlled trials, are needed before creating comprehensive guidelines for treating CPP.

Re-Examining Myofascial Pain Syndrome: Toward Biomarker Development and Mechanism-Based Diagnostic Criteria

PURPOSE OF REVIEW

We discuss the need for a mechanism-based diagnostic framework with a focus on the development of objective measures (e.g., biomarkers) that can potentially be added to the diagnostic criteria of the syndrome. Potential biomarkers are discussed in relation to current knowledge on the pathophysiology of myofascial pain syndrome (MPS), including alterations in redox status, inflammation, and the myofascial trigger point (MTrP) biochemical milieu, as well as imaging and neurophysiological outcomes. Finally, we discuss the long-term goal of conducting a Delphi survey, to assess the influence of putative MPS biomarkers on clinician opinion, in order to ultimately develop new criteria for the diagnosis of MPS.

RECENT FINDINGS

Myofascial pain syndrome (MPS) is a prevalent healthcare condition associated with muscle weakness, impaired mood, and reduced quality of life. MPS is characterized by the presence of myofascial trigger points (MTrPs): stiff and discrete nodules located within taut bands of skeletal muscle that are painful upon palpation. However, physical examination of MTrPs often yields inconsistent results, and there is no gold standard by which to diagnose MPS. The current MPS diagnostic paradigm has an inherent subjectivity and the absence of correlation with the underlying pathophysiology. Recent advancements in ultrasound imaging, systemic biomarkers, MTrP-specific biomarkers, and the assessment of dysfunction in the somatosensorial system may all contribute to improved diagnostic effectiveness of MPS.

Ultrasound imaging and guidance in peripheral nerve entrapment: hydrodissection highlighted

Ultrasound (US) imaging has become one of the most useful modalities to assess peripheral nerve disorders. Nowadays, it is as important as nerve conduction studies and electromyography for peripheral nerve entrapment. Additionally, US is also helpful in guiding a possible intervention. As peripheral nerves are tiny, palpation-guided injections are really challenging for precisely targeting the nerves. By using US, perineural injections have significantly become safe and effective. Recently, US-guided hydrodissection has emerged as the mainstream for nerve entrapment. Accordingly, this review aims to summarize and update the mechanism and evidence regarding this imperative procedure for neuropathic pain management. Furthermore, the pathogenesis, anatomic features, US findings and histological correlations of nerve entrapment syndromes will also be discussed in this article.
