Anorectal and Pelvic Pain

Exploring Psychological Factors and Brain Alterations in Functional Anorectal Pain Patients: Insights From Multimodal Magnetic Resonance Imaging Investigations

BACKGROUND

Functional anorectal pain (FAP) is classified as one of the disorders of gut-brain interaction (DGBI). It involves the impairments of anorectal afferents and disrupted gut-brain communication. However, neuroimaging studies focused on FAP are lacking.

METHODS

A total of 25 FAP patients and 18 healthy controls (HC) underwent structural magnetic resonance imaging (MRI), diffusion tensor imaging (DTI), resting-state functional MRI (rs-fMRI) scans, and collection of demographic data, mental health assessment scales and pain assessment questionnaires. Voxel-based morphometry (VBM), tract-based spatial statistics (TBSS), regional homogeneity (ReHo), and amplitude of low-frequency fluctuations (ALFF) were utilized to analyze the imaging data. Correlation analyses were conducted to explore the relationships between the neuroimaging findings and clinical symptoms.

KEY RESULTS

Functional anorectal pain (FAP) patients exhibited higher levels of anxiety, depression scores and lower sleep quality compared to HC. VBM analysis revealed increased gray matter volume (GMV) in the bilateral fusiform, right parahippocampal, bilateral inferior temporal gyrus (ITG), and decreased GMV in the right superior frontal gyrus (SFG), left middle frontal gyrus (MFG), bilateral inferior frontal gyrus (IFG), left Calcarine, bilateral middle occipital gyrus (MOG), left middle temporal gyrus (MTG) in FAP patients. TBSS analysis showed decreased fractional anisotropy (FA) in the superior longitudinal fasciculus (SLF), anterior thalamic radiation (ATR), and forceps minor in the FAP patients. Additionally, increased ALFF in the right cerebellum and increased ReHo in the right MFG were observed in the FAP patients.

CONCLUSIONS AND INFERENCES

These findings showed a worse psychological condition and suggested neuroanatomical and neurofunctional alterations associated with pain processing, emotion regulation, and cognitive control in FAP patients.

Clinical application of repetitive transcranial magnetic stimulation in the treatment of chronic pelvic pain syndrome: a scoping review

Introduction

Chronic pelvic pain syndrome is a common condition characterized by persistent symptoms that are difficult to treat. Repetitive transcranial magnetic stimulation (rTMS) is considered a safe treatment option for alleviating chronic pelvic pain, but different stimulation protocols can affect pain relief outcomes. Establishing an optimal stimulation protocol can enhance the uniformity and consistency of rTMS to provide a potentially effective therapeutic intervention. This review sought to systematically review and assess the existing literature on transcranial magnetic stimulation in patients experiencing chronic pelvic pain syndrome, evaluate the therapeutic efficacy, and determine the most effective stimulation protocol.

Methods

A comprehensive search was conducted across three databases, supplemented by manual searches. Two researchers independently reviewed and extracted relevant studies and subsequently performed a thorough analysis of all available clinical data.

Results

A total of eight studies were ultimately incorporated into the analysis. These comprised two randomized controlled trials, one self-controlled trial, two case reports, and three prospective studies. All studies demonstrated a notable reduction in pain scores post-treatment.

Conclusion

rTMS has demonstrated efficacy in alleviating pain in individuals suffering from chronic pelvic pain syndrome. It is regarded as a safe intervention with minimal adverse effects. Nonetheless, the variability observed across studies hindered our ability to conclusively determine the most effective stimulation sites and parameters. Additional research is essential to reduce bias, enhance methodological rigor, and ascertain the optimal conditions and indications for brain stimulation to optimize the therapeutic effectiveness of rTMS.

Chronic Primary Pelvic Pain Syndromes in Women: A Comprehensive Review

Chronic pelvic pain (CPP) in women is a multifactorial and complex condition. It often remains undiagnosed or inadequately treated. Despite its high prevalence, CPP continues to be a taboo subject, leading to delays in seeking medical care. Chronic primary pelvic pain syndromes (CPPPS) are pain conditions without an obvious underlying diagnosis, including painful bladder syndrome, vulvodynia, genito-pelvic pain/penetration disorder, levator ani syndrome, proctalgia fugax, myofascial syndrome, pudendal neuralgia, and coccyx pain syndrome. A comprehensive review of the literature was conducted to understand the most common forms of CPPPS in women, focusing on diagnostic criteria, pathophysiology, and treatment options. Due to the complexity of CPPPS and varied treatment responses, management requires a multidisciplinary approach. Although various treatment modalities exist, no single strategy is universally effective, emphasizing the need for individualized care. Future research should prioritize refining diagnostic criteria and investigating new therapeutic strategies.

The role of TRPV1 in chronic prostatitis: a review

Chronic prostatitis is a prevalent male urinary system disorder characterized by pelvic discomfort or pain, bladder dysfunction, sexual dysfunction, and infertility. Pain and lower urinary tract symptoms (LUTS) are the most common symptoms, significantly impacting patients' quality of life and driving them to seek medical attention. Transient receptor potential vanilloid subtype 1 (TRPV1) is a non-selective calcium ion-dependent cation channel in the TRPV channel family that is widely distributed in neural tissue and plays a role in signal transmission. In this review, we provide a comprehensive overview of the current understanding of the role of TRPV1 in chronic prostatitis. The discussion focuses on the connection between TRPV1 and prostatitis pain and LUTS, and highlights the potential for targeting this channel in the development of novel treatment strategies.

Thickness of the abdominal wall and pelvic floor dysfunctions in men who practice crossfit vs no crossfit: An observational study

INTRODUCTION

The objective of this study is to compare the thickness of the transverse abdominis, internal oblique, external oblique, rectus abdominis, and rectus abdominis distance, the quality of life (SF-36), the presence of chronic pelvic pain (CPPQ-Mohedo), and sexual dysfunction (IIEF) in men who practice CrossFit® versus men who do not.

DESIGN, SETTING, PARTICIPANTS, AND MAIN OUTCOME MEASURES

Sixty-four healthy men with an average age of 37.19 were recruited at a private sports club and divided into two groups for this cross-sectional observational study. Additionally, participants completed the CPPQ-M, IIEF, and SF-36 questionnaires.

RESULTS

Significant differences were found in the thickness of the internal oblique at rest (p = 0.018, d = 0.61), which was greater in the CrossFit® group. In the SF-36 quality of life questionnaire (p = 0.05, d = 0.50), the CrossFit® group also obtained a higher score.

CONCLUSION

CrossFit® improves the quality of life and self-esteem of the participants, in addition to increasing the thickness of the internal oblique. Neither more chronic pelvic pain nor more erectile dysfunction was observed in the CrossFit® group.

Evaluation and management of chronic anorectal and pelvic pain syndromes: Italian Society of Colorectal Surgery (SICCR) position statement

Chronic pelvic pain is a hidden issue which needs to involve many different usually uncoordinated specialists. For this reason there is a risk that treatments, in the absence of well-defined pathways, common goals, and terminology, may be poorly effective. The aim of the present paper is to summarize the evidence on anorectal pelvic pain, offering useful evidence-based practice parameters for colorectal surgeons' daily activity. Analysis of chronic anorectal and pelvic pain syndromes, the diagnostic and clinical optimal needs for evaluation, and the innumerable low evidence treatments and therapeutic options currently available suggests that a multimodal individualized management of pain may be the most promising approach. The limited availability of dedicated centers still negatively affects the applicability of these principles.

Acupuncture Versus Biofeedback for Treatment of Functional Anorectal Pain

BACKGROUND/AIMS

Functional anorectal pain is one of several types of functional anorectal disorders. In this study, we compared the effectiveness of acupuncture (intervention) and biofeedback (control) as treatment for patients with functional anorectal pain.

MATERIALS AND METHODS

This prospective, single-center, randomized, and comparative study examined 68 patients with functional anorectal pain who were recruited from June 2017 to January 2019 at the Nanjing Hospital of Chinese Medicine Affiliated to Nanjing University of Chinese Medicine. Patients were randomly assigned to receive acupuncture or biofeedback. Patients in the acupuncture group received acupuncture at Zhongliao (BL33), Xialiao (BL34), Ganshu (BL18), Shenshu (BL23), and Dachangshu (BL25). Patients in the biofeedback group received pelvic floor biofeedback therapy, consisting of Kegel pelvic floor muscle training and electrical stimulation. Patients in both groups received 20 treatments over 4 weeks. The primary outcome was pain score on a visual analog scale, and the secondary outcomes were results from the MOS 36-item short-form health survey (SF-36) quality of life questionnaire, the self-rating depression scale, and the self-rating anxiety scale.

RESULTS

Visual analog scale pain scores significantly decreased in both of the groups with treatment (both P < .01). The final visual analog scale score was significantly lower in patients with pelvic floor dyssynergia who were treated with biofeedback (1.40 ± 0.97 vs. 5.30 ± 1.70) (P < .05). The 2 groups had similar decreases in self-rating depression scale and self-rating anxiety scale scores. Intriguingly, the acupuncture group had better mental health outcomes (P <.05).

CONCLUSION

Both acupuncture and biofeedback therapy reduced the pain of patients with functional anorectal pain. Biofeedback provided more relief in patients with pelvic floor dyssynergia, and acupuncture provided greater improvements in mental health status.

Psychological status of patients with functional anorectal pain and treatment efficacy of paroxetine in alleviating the symptoms: a retrospective study

The aim of this study was to investigate the clinical characteristics, psychological status, sleep quality, and quality of life of patients with functional anorectal pain (FAP). The study also assessed the treatment efficacy of paroxetine in alleviating FAP symptoms. A retrospective comparative study of forty-three patients with FAP who were first treated with an anal plug compound glycolate suppository versus paroxetine combined with anal plug compound glycolate suppository between November 2021 and August 2022. Pain, quality of life, depression, anxiety and sleep quality were assessed before and after treatment by the Chinese version of the Short-Form McGill Pain Questionnaire-2 (SF-MPQ-2), Health-related quality of life scale (The 12-Item Short-Form Health Survey, SF-12), 17-item Hamilton Depression Rating Scale (HDRS), 14-item Hamilton Anxiety Scale (HAMA), and Pittsburgh Sleep Quality Index (PSQI). A total of 46.5% of patients with FAP were found to have anxiety symptoms (HAMA ≥ 7), 37.2% of patients with FAP were found to have depressive symptoms (HDRS ≥ 8). A total of 32.6% of patients with FAP had sleep disorders (PSQI > 10). Within 1 week after drug withdrawal, the short-term efficacy rate of oral paroxetine was 95.5%. After treatment, the symptom pain score (VAS) and sleep score were lower than those before treatment (P < 0.01). In the areas of vitality (VT), Social Functioning (SF), and Mental Health (MH), the difference between the pre-treatment and 8 weeks posttreatment scores of the study group and the control group was statistically significant (P < 0.05). FAP patients have obvious symptoms of anxiety and depression, and the incidence of sleep disturbance is prevalent. Paroxetine, a typical serotonin reuptake inhibitor (SSRI), was able to alleviate depression, anxiety, and pain symptoms in FAP, which might have clinical application prospects.

Erectile dysfunction, depression, and anxiety in patients with functional anorectal pain: a case-control study

BACKGROUND

Men with functional anorectal pain (FARP) report having erectile dysfunction (ED) and significant changes in psychological status.

AIM

The study sought to investigate the risk factors associated with FARP among male Chinese outpatients, alongside the impact of FARP on patients' ED, depression, and anxiety.

METHODS

This case-control study included 406 male participants, divided into FARP (n = 323) and healthy control (n = 73) groups. Demographic and disease characteristics were collected from the patients, and the 5-item International Index of Erectile Function, Patient Health Questionnaire-9, and Generalized Anxiety Disorder 7 were used to assess erectile function, depression, and anxiety symptoms. Baseline characteristics were described using descriptive statistics, logistic regression analysis identified factors influencing FARP, and its association with ED, depression, and anxiety were analyzed using linear and ordinal logistic regression analyses. Validity was ensured through subgroup and sensitivity analyses.

OUTCOMES

The primary outcome was the association between FARP and ED, depression, and anxiety; the secondary outcome was the influencing factors of FARP such as lifestyle and work habits.

RESULTS

Men with FARP were likely to have more serious ED (59.8% vs 32.9%), depression (20.7% vs 4.1%), and anxiety(31.5% vs 12.3%); have lower 5-item International Index of Erectile Function scores; or have higher Patient Health Questionnaire-9 and Generalized Anxiety Disorder 7 scores compared with unaffected participants. Alcohol intake, family relationship, high work pressure, and prolonged bowel movements were significantly associated with FARP severity. The association between FARP with ED, depression, and anxiety was statistically significant in both crude and adjusted models. FARP was associated with 2.47, 2.73, and 2.67 times higher risk for ED, depression, and anxiety, respectively. An increase pain severity increased the incidence of ED (moderate pain: 4.80 times, P < .000; severe pain: 3.49 times, P < .004), depression (moderate pain: 1.85 times, P < .017; severe pain: 2.04 times, P < .037), and anxiety (moderate pain: 1.86 times, P < .014).Clinical Implications: Changes in lifestyle and work habits can help prevent pain symptom exacerbation. Attention to erection and psychological issues in patients with FARP and interdisciplinary comprehensive treatment may improve the efficacy.

STRENGTHS AND LIMITATIONS

The study highlights a correlation between FARP and ED, depression, and anxiety, with pain severity being a contributing factor. However, the study's limitations include a small sample size and potential recall bias, and other sexual functions were not thoroughly explored.

CONCLUSION

Patients with FARP have a higher prevalence of ED, depression, and anxiety, which increase with pain severity. Factors such as alcohol intake, work pressure, prolonged sitting, and longer defecation times are significantly correlated with FARP pain severity.

Prevalence and Correlates of Depression and Anxiety in Patients with Functional Anorectal Pain

Purpose

Patients with functional anorectal pain (FAP) often experience psychological distress, impaired quality of life, increased healthcare utilisation, and even suicidal tendencies. However, limited data exists on the psychological correlates of FAP in Chinese patients. Therefore, this study aimed to examine the prevalence of depression, anxiety, and related psychosocial factors in Chinese patients with FAP.

Methods

We used a cross-sectional research design and recruited 100 patients with FAP from SuBei Hospital's multidisciplinary clinic for pelvic floor disorders between January and December 2021. Information on patients' demographic and disease characteristics was also collected. Depressive and anxiety symptoms were assessed using the Patient Health Questionnaire Depression (PHQ-9) and the Generalised Anxiety Disorder Questionnaire (GAD-7). Multiple logistic regression analysis was used to examine factors associated with depression and anxiety.

Results

The prevalence of depressive and anxiety symptoms among patients with FAP was 55% and 46%, respectively. Being a woman, specific marital status (single, divorced, separated, or widowed), longer FAP duration, and sleep disturbance were significantly associated with an increased risk of depressive symptoms. Additionally, specific marital status (single, divorced, separated, or widowed), sleep disturbance, and high Visual Analogue Scale scores were associated with anxiety symptoms.

Conclusion

Depressive and anxiety symptoms are prevalent in patients with FAP. Several socio-demographic and clinical predictors have been identified. There is a need for psychologists to be involved in the treatment of patients with FAP. Thus, multidisciplinary treatment may be the optimal treatment strategy.

Pelvic pain is a common prolapse symptom and improvement after ventral mesh rectopexy is more frequent than deterioration or de novo pain

AIM

The aim of this work was to assess the relationship between pelvic pain and rectal prolapse both before prolapse surgery and in the long term after ventral mesh rectopexy (VMR).

METHOD

Patients undergoing VMR between 2004 and 2017 were contacted. Outcomes including the severity of pelvic pain were recorded using a numeric rating scale.

RESULTS

Four hundred and seventy eight of the 749 patients (64%) were successfully contacted. Of these, 39% reported pre-existing pelvic pain prior to VMR (group A) and 61% were pain free (group B). The median follow-up time was 8.0 years (interquartile range 5.0-10.0 years). Symptoms of obstructed defaecation were significantly more common (p = 0.002) in group A (91/187, 49%) than in group B (101/291, 35%). In contrast, faecal incontinence was more common (p = 0.007) in group B (75/291, 26%) than in group A (29/187, 15%). In group A, 76% showed improvement in pelvic pain after VMR: 61% were pain free and 39% had partial improvement in their pre-existing pelvic pain. Patients with persistent pelvic pain were younger (p = 0.01) and more likely to have revisional surgery after VMR (p = 0.0003), but there was no relation to the indication for surgery (p = 0.59). In group B, 15% reported de novo pelvic pain after VMR, and this was more common in women under 50 years old (p = 0.001), when obstructed defaecation was the indication (p = 0.03), in mesh erosion (p = <0.05) and when associated with revisional surgery (p = 0.005).

CONCLUSION

Pelvic pain is common (39%) in patients undergoing prolapse surgery, and VMR improves this pain in most patients (76%). However, a significant number of patients fail to improve (12%), experience worsening of pain (12%) or develop de novo pelvic pain (15%).

Myofascial Pain Syndrome in Women with Primary Dysmenorrhea: A Case-Control Study

There is limited information on myofascial trigger points (MTrPs) and specific symptoms of chronic pelvic pain and, more specifically, dysmenorrhea. The objective of this study was to determine whether patients suffering from primary dysmenorrhea present alterations in mechanosensitivity and pain patterns, and greater presence of MTrPs in the abdominal and pelvic floor muscles. A case-control study was carried out with a total sample of 84 participants distributed based on primary dysmenorrhea and contraceptive treatment. The sample was divided into four groups each comprising 21 women. Data on pain, quality of life, and productivity and work absenteeism were collected; three assessments were made in different phases of the menstrual cycle, to report data on pressure pain threshold, MTrP presence, and referred pain areas. One-way ANOVA tests showed statistically significant differences (p < 0.01) between the groups, for the Physical Health domain and the total score of the SF-12 questionnaire, and for all the domains of the McGill questionnaire; but no significant differences were found in the data from the WPAI-GH questionnaire. Statistically significant data (p < 0.01) were found for mechanosensitivity in the abdominal area and limbs, but not for the lumbar assessment, within the group, with very few significant intergroup differences. The frequency of active MTrPs is higher in the groups of women with primary dysmenorrhea and during the menstrual phase, with the prevalence of myofascial trigger points of the iliococcygeus muscle being especially high in all examination groups (>50%) and higher than 70% in women with primary dysmenorrhea, in the menstrual phase, and the internal obturator muscle (100%) in the menstrual phase. Referred pain areas of the pelvic floor muscles increase in women with primary dysmenorrhea.

Benign Anorectal Disorder Management in Low-Resource Settings

There are many benign anorectal disorders, which can make patients seek care. In low-resource settings, the incidence of those pathologies is not different from the industrialized and western world. However, an interesting difference colorectal surgeons and gastroenterologists can face is the fact that many patients do not seek help or are not aware and have little opportunities to be helped. Latin America population is estimated to be around 8% of the world population, with Brazil having the largest percentage. Infectious diseases, which were previously under control or were steadily declining, have emerged. For example, we have seen resurgence of dengue, malaria, and syphilis in pregnancy, as well as other sexually transmitted diseases that can affect the anorectal region. In this article, we will address the most common benign anorectal disorders.

Proposal of an algorithm for the management of rectally inserted foreign bodies: a surgical single-center experience with review of the literature

BACKGROUND

Retained rectal foreign bodies (RFBs) are uncommon clinical findings. Although the management of RFBs is rarely reported in the literature, clinicians regularly face this issue. To date, there is no standardized management of RFBs. The aim of the present study was to evaluate our own data and subsequently develop a treatment algorithm.

METHODS

All consecutive patients who presented between January 2006 and December 2019 with rectally inserted RFBs at the emergency department of the Klinikum Stuttgart, Germany, were retrospectively identified. Clinicopathologic features, management, complications, and outcomes were assessed. Based on this experience, a treatment algorithm was developed.

RESULTS

A total of 69 presentations with rectally inserted RFBs were documented in 57 patients. In 23/69 cases (33.3%), the RFB was removed transanally by the emergency physician either digitally (n = 14) or with the help of a rigid rectoscope (n = 8) or a colonoscope (n = 1). In 46/69 cases (66.7%), the RFB was removed in the operation theater under general anesthesia with muscle relaxation. Among these, 11/46 patients (23.9%) underwent abdominal surgery, either for manual extraction of the RFB (n = 9) or to exclude a bowel perforation (n = 2). Surgical complications occurred in 3/11 patients. One patient with rectal perforation developed pelvic sepsis and underwent abdominoperineal extirpation in the further clinical course.

CONCLUSION

The management of RFBs can be challenging and includes a wide range of options from removal without further intervention to abdominoperineal extirpation in cases of pelvic sepsis. Whenever possible, RFBs should obligatorily be managed in specialized colorectal centers following a clear treatment algorithm.

Pelvic floor physical therapy in patients with chronic anal fissure: a randomized controlled trial

Background

A chronic anal fissure is a common, painful condition with great impact on daily life. The exact pathogenesis has not been fully elucidated and treatment varies. A large percentage of patients experience pelvic floor dysfunction (dyssynergia and increased pelvic floor muscle tone). The aim of our study was to investigate the effect of pelvic floor physical therapy in patients with chronic anal fissure.

Methods

Between December 2018 and July 2021, at the Proctos Clinic in the Netherlands, patients with chronic anal fissure and pelvic floor dysfunction were randomly assigned to an intervention group, receiving 8 weeks of pelvic floor physical therapy including electromyographic biofeedback or assigned to a control group receiving postponed pelvic floor physical therapy. The primary outcome was muscle tone at rest during electromyographic registration of the pelvic floor before and after pelvic floor physical therapy. Secondary outcomes contained healing of the fissure, pain ratings, improvement of pelvic floor function, and complaint reduction measured with a proctology-specific patient-reported outcome measurement. Endpoints were measured at 8- and 20-week follow-up.

Results

One hundred forty patients were included in the study, 68 men (48.6%) and 72 women (51.4%) with a mean age of 44.5 ± 11.1 (range 19–79) years. Mean resting electromyographic values of the pelvic floor in the intervention group significantly improved from pre- to post-treatment (p < 0.001) and relative to controls (mean estimated difference between groups − 1.88 µV; 95% CI, − 2.49 to − 1.27 (p < 0.001) at first follow-up and remained significant from baseline at 20-week follow-up (p < 0.001). The intervention group performed better compared to the control group on all secondary outcomes, i.e., healing of the fissure (55.7% of the patients vs 21.4% in control, pain ratings (p < 0.001), diminished dyssynergia (p < 0.001), complaint reduction (p < 0.001), and decrease of pelvic floor muscle tone (p < 0.05) at first follow-up.

Conclusions

The findings of this study provide strong evidence that pelvic floor physical therapy is effective in patients with chronic anal fissure and pelvic floor dysfunction and supports its recommendation as adjuvant treatment besides regular conservative treatment.

Dyssynergic Defecation and Other Evacuation Disorders

Constipated patients are frequently referred to gastroenterologists for symptoms refractory to lifestyle modifications and laxatives. Dyssynergic defecation, the dyscoordination of rectoanal, abdominal, and pelvic floor muscles to facilitate defecation, is a major cause of refractory primary constipation. Understanding of the diagnosis, evaluation, and management of dyssynergic defecation and other evacuation disorders will allow providers to effectively manage these patients. This review focuses on the definition, pathophysiology, evaluation, and treatment of dyssynergic defecation and other evacuation disorders. Emerging treatments for these disorders include home biofeedback therapy for dyssynergic defecation and translumbosacral neuromodulation therapy for levator ani syndrome.

A Pain in the Butt: Hemorrhoids, Fissures, Fistulas, and Other Anorectal Syndromes

Painful and bothersome anorectal syndromes can be a diagnostic and therapeutic challenge for clinicians because structural and functional abnormalities may often coexist and require a multidisciplinary approach to management. Although it is often difficult to attribute all of a patient's anorectal symptoms to a singular disorder with definitive intervention and cure, improving quality of life, treating coexistent conditions such as functional constipation and/or defecation disorders, addressing psychological comorbidities if present, and confirming there is no evidence of inflammatory or malignant conditions are top priorities.

Management of chronic anal fissure: results of a national survey among gastrointestinal surgeons in the Netherlands

BACKGROUND

Chronic anal fissure (CAF) is a common, bothersome condition frequently accompanied by pelvic floor complaints. Despite current guidelines, optimal management is challenging. The aim of this study is to evaluate current management of CAF among gastrointestinal surgeons in the Netherlands.

METHODS

Dutch gastrointestinal surgeons and residents were sent a survey invitation by email, which was available online between June 2021 and September 2021. The questionnaire consisted of 21 questions concerning work experience, physical examination, diagnostic and surgical techniques, and follow-up.

RESULTS

Overall, 106 (33%) respondents completed the survey. Most respondents (59%) had at least 10 years of experience in treating CAF. Only 23% always addressed pelvic floor complaints. Fifty-one percent performed digital rectal examination and 22% always, or almost always, examined the pelvic floor muscles. Most respondents started treatment with fibers and/or laxatives and ointment (96%). Diltiazem was in 90% the preferred ointment. Twenty-two percent referred patients for pelvic floor physical therapy. Botulinum toxin was in 54% performed under general or spinal anesthesia or sedation. The surgical procedure of choice was fissurectomy (71%) followed by lateral internal sphincterotomy (27%). Fissurectomy was in 51% always combined with botulinum toxin. Fifty-seven percent of the respondents preferred a physical follow-up appointment.

CONCLUSION

Guideline recommendations are largely followed in the Netherlands, starting with conservative measures followed by surgical procedures. Surgeons do not consistently assess pelvic floor complaints, nor do they routinely examine the pelvic floor muscles. Awareness of pelvic floor dysfunctions is important to refer patients for pelvic floor physical therapy.

Urodynamic autonomic bladder dysfunction in women with complex chronic pelvic pain is associated with small fiber polyneuropathy

AIMS

Small fiber neuropathy/polyneuropathy (SFN) has been found to be present in 64% of complex (refractory or multisystem) chronic pelvic pain (CPP) patients. The small fiber dysfunction seen in SFN can negatively impact autonomic control of micturition in addition to pain. This study investigated the clinical association of autonomic dysfunction (detrusor underactivity and primary bladder neck obstruction [BNO]) on video urodynamics (VUDS) with SFN in patients with CPP.

METHODS

This was a retrospective observational study, querying data from patients with complex CPP. Inclusion criteria were: the presence of complex (refractory or multisystem) CPP, and completion of both (1) subspecialty autonomic neurology evaluation for SFN and (2) high-quality VUDS performed according to ICS standards. Autonomic bladder dysfunction (BNO or detrusor underactivity) on VUDS was compared to the presence of SFN.

RESULTS

Thirty-two female patients with complex CPP met criteria. Of the 32, 23 (72%) were found to have SFN. Patient with autonomic bladder dysfunction (BNO or detrusor underactivity) were more likely to have SFN (OR = 9.5 [95% CI: 1.641, 55.00], p = 0.007). Post-void residual volume was higher in the SFN group (p = 0.011 [95% CI: 13.12, 94.0]) and symptoms of urge urinary incontinence were more likely to be present (p = 0.000 [95% CI: -3.4, -1.25]).

CONCLUSIONS

Patients with complex CPP with autonomic bladder dysfunction are more likely to have SFN. This suggests patients with complex CPP should be considered for diagnosis and treatment of SFN, particularly if BNO or detrusor underactivity is noted on VUDS evaluation.

Pelvic floor physical therapy in the treatment of chronic anal fissure (PAF-study): Study protocol for a randomized controlled trial

BACKGROUND

Chronic anal fissure (CAF) is a common cause of severe anorectal pain with a high incidence rate. Currently, a wide range of treatment options are available with recurrence rates varying between 7 and 42%. Pelvic floor physical therapy (PFPT) is a treatment option for increased pelvic floor muscle tone and dyssynergia which often accompanies CAF. However, literature on this subject is scarce. The Pelvic Floor Anal Fissure (PAF)-study aims to determine the efficacy and effectiveness of PFPT on improvement on pelvic floor muscle tone and function, pain, healing of the fissure, quality of life and complaint reduction in patients with CAF.

METHODS

The PAF-study is a single-centre, two armed, randomized controlled trial. Patients with CAF and pelvic floor dysfunction are eligible for inclusion. Exclusion criteria include abscess, fistula, Crohn's disease, ulcerative colitis, anorectal malignancy, prior rectal radiation, and pregnancy. A total of 140 patients will be randomized for either PFPT or postponed treatment of PFPT.The primary outcome is tone at rest during electromyographic registration of the pelvic floor before and after therapy. Secondary outcomes consist of healing of the fissure, pain ratings, improvement of pelvic floor function, complaint reduction and quality of life. Primary and secondary endpoints are measured at 8 and 20 weeks and at 1-year follow-up.

DISCUSSION

Currently, there is a gap in treatment modalities between conservative management and surgery. This manuscript prescribes the rationale, design, and methodology of a randomized controlled trial investigating PFPT as a treatment option for patients with CAF.

Opioid use among patients with pain syndromes commonly seeking surgical consultation: A retrospective cohort

BACKGROUND

Surgeons often see patients with pain to exclude organic pathology and consider surgical treatment. We examined factors associated with long-term opioid therapy among patients with foot/ankle, anorectal, and temporomandibular joint pain to aid clinical decision making.

METHODS

Using the IBM MarketScan® Research Database, we conducted a retrospective cohort analysis of patients aged 18-64 with a clinical encounter for foot/ankle, anorectal, or temporomandibular joint pain (January 2007-September 2015). Multivariable logistic regression was used to estimate adjusted odds ratios for factors associated with long-term opioid therapy, including age, sex, geographic region, pain condition, psychiatric diagnoses, and surgical procedures in the previous year.

RESULTS

The majority of the cohort of 1,500,392 patients were women (61%). Within the year prior to the first clinical encounter for a pain diagnosis, 14% had an encounter for a psychiatric diagnosis, and 11% had undergone a surgical procedure. Long-term opioid therapy was received by 2.7%. After multivariable adjustment, older age (age 50-64 vs. 18-29: aOR 4.47, 95% CI 4.24-4.72, p < 0.001), region (South vs. Northeast, aOR 1.76, 95% CI 1.70-1.81, p < 0.001), recent surgical procedure (aOR 1.83, 95% CI 1.78-1.87, p < 0.001), male sex (aOR 1.14, 95% CI 1.12-1.16, p < 0.001) and recent psychiatric diagnosis (aOR 2.49, 95% CI 2.43-2.54, p < 0.001) were independently associated with long-term opioid therapy.

CONCLUSION

Among patients with foot/ankle, anorectal, or temporomandibular joint pain, the risk of long-term opioid therapy significantly increased with older age, recent psychiatric diagnoses and surgical history. Surgeons should be aware of these risk factors in order to make high quality clinical decisions in consultations with these patients.

Using the UPOINT system to manage men with chronic pelvic pain syndrome

OBJECTIVE

: To outline our approach for the evaluation and management of patients with chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS) based on our interpretation and application of currently available evidence.

METHODS

: CP/CPPS in men is a medical condition that plagues both the patient and the practitioner, as it is widely believed to be poorly understood and difficult to treat. While pelvic pain is typically the predominant symptom, many men may exhibit voiding symptoms, sexual dysfunction and psychiatric complaints. Still, most studies of CP/CPPS management have evaluated singular treatments, without focussing on individual patients' clinical phenotypes. This is a clinically practical mini-review based on the authors' interpretation and application of currently available evidence related to management of CP/CPPS.

RESULTS

: Patient evaluation should consist of history and physical examination (with focus on the genitourinary and digital rectal examination), laboratory tests (including urine analysis and urine culture with consideration of pre- and post-prostate massage urine cultures), post-void residual, and questionnaires including the National Institutes of Health Chronic Prostatitis Symptoms Index, which helps assess symptom severity and treatment response. Once CP/CPPS is diagnosed, the UPOINT phenotype system, which classifies patients into six domains: Urinary, Psychosocial, Organ Specific, Infectious, Neurological/systemic and Tenderness of skeletal muscles, is used to guide treatment. Each domain is characterised by specific complaints and thus is responsive to distinct treatments. As patients may be grouped into multiple domains, each patient's overall multimodal treatment can vary.

CONCLUSION

: Using the UPOINT phenotype system is a holistic approach that can yield significant benefits for patients with CP/CPPS.

Percutaneous Tibial Nerve Stimulation in Chronic Post-Surgical Anorectal Pain: A Case Report

<b><i>Introduction:</i></b> Anorectal pain is a symptom with a negative impact on quality of life and it can sometimes develop into a chronic pain syndrome. Structural anorectal pain is treated according to the underlying pathology. In situations of chronic post-surgical pain that is refractory to conventional therapeutic approaches, percutaneous tibial nerve stimulation (PTNS) is an option. PTNS is a neurostimulation technique used in the treatment of lower urinary tract dysfunction. There has been increasing evidence of its benefits for improving other conditions, such as chronic pelvic pain (CPP) and faecal incontinence (FI). <b><i>Case Presentation:</i></b> We report a case of a 45-year-old woman with chronic post-surgical anorectal pain (CPAP) treated with PTNS. The patient reported a consistent and dramatic decrease in both the frequency and intensity of pain, assessed by the Brief Pain Inventory (BPI). A decrease in the pain interference with mood, normal work, and walking/mobility was also noted, as evaluated by BPI and EQ-5D-3L questionnaires. <b><i>Discussion:</i></b> Neuromodulation treatments have been reported as effective for anorectal pain, but reports on the use of PTNS are rare. The tibial nerve is easily accessible and provides an optimal site for neurostimulation without the need of an operating room or anaesthesia. The overall improvement observed in this case of chronic anorectal pain suggests a potential new area of research for PTNS.

Sex- and Gender-Related Differences in Common Functional Gastroenterologic Disorders

Functional gastrointestinal (GI) disorders (FGIDs) result from central and peripheral mechanisms, cause chronic remitting-relapsing symptoms, and are associated with comorbid conditions and impaired quality of life. This article reviews sex- and gender-based differences in the prevalence, pathophysiologic factors, clinical characteristics, and management of functional dyspepsia (FD) and irritable bowel syndrome (IBS) that together affect approximately 1 in 4 people in the United States. These conditions are more common in women. Among patients with IBS, women are more likely to have severe symptoms and coexistent anxiety or depression; constipation or bloating and diarrhea are more common in women and men, respectively, perhaps partly because defecatory disorders, which cause constipation, are more common in women. Current concepts suggest that biological disturbances (eg, persistent mucosal inflammation after acute gastroenteritis) interact with other environmental factors (eg, abuse) and psychological stressors, which influence the brain and gut to alter GI tract motility or sensation, thereby causing symptoms. By comparison to a considerable understanding of sex-based differences in the pathogenesis of visceral hypersensitivity in animal models, we know less about the contribution of these differences to FGID in humans. Slow gastric emptying and colon transit are more common in healthy women than in men, but effects of gonadal hormones on colon transit are less important than in rodents. Although increased visceral sensation partly explains symptoms, the effects of sex on visceral sensation, colonic permeability, and the gut microbiome are less prominent in humans than rodents. Whether sex or gender affects response to medications or behavioral therapy in FD or IBS is unclear because most patients in these studies are women.

Efficacy of radial extracorporeal shock wave therapy for chronic prostatitis/chronic pelvic pain syndrome: A protocol for systematic review

BACKGROUND

Prostatitis is a common urogenital system disease in men which affects 5% to 9% of adult men worldwide and accounts for approximately 8% of visits to urologists. In the past years, its pathogenesis is complicated and the classification of it is not clear, so the effect of treatment measures is not significant. Recently, the treatment of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) includes nonsteroidal anti-inflammatory drugs, phytotherapy, hormonal therapy, alpha-blockers, anti-anxiolytic, and acupuncture, which provide more choice for the urologist. But there still are some limitations. scholars. Many studies suggest radial extracorporeal shock wave therapy may be the better option in the treatment of CP/CPPS. However, the efficacy and safety of it still lack solid evidence.

METHODS AND ANALYSIS

The electronic databases of MEDLINE, PubMed, Web of Science, EMBASE, Cochrane Library, Clinicaltrials.org, China National Knowledge Infrastructure Database, Wan fang Database, China Biology Medicine Database, VIP Science Technology Periodical Database, Chinese Clinical Trial Registry will be retrieved. All the randomized controlled trials of radial extracorporeal shock wave therapy (rESWT) for patients with CP/CPPS will be included. We will evaluate the outcomes including National Institutes of Health Chronic Prostatitis Symptom Index, visual analog scale, international prostate symptom score, international index of erectile function-5, and conduct this study strictly according to the Cochrane Handbook for Systematic Reviews of Interventions.

RESULTS

The current study is a protocol for systematic review and meta-analysis without results, and data analysis will be carried out after the protocol. We will share our findings on October 31st of 2021.

CONCLUSION

rESWT as a noninvasive treatment with no pain, which will be accepted more easily. Although some studies have suggested that rESWT can relieve the symptoms of patients, the efficacy and safety of it still lack solid evidence. To address this limitation scientifically and systematically, this study will inspect the efficacy and safety of the rESWT treatment in patients with CP/CPPS by integrating various studies.

ETHICS AND DISSEMINATION

Formal ethical approval is not required in this protocol. We will collect and analyze data based on published studies, and since there are no patients involved in this study, individual privacy will not be under concerns. The results of this review will be disseminated to peer-reviewed journals or submit to related conferences.

Anorectal Disorders: An Update

Anorectal disorders encompass structural, neuromuscular, and functional disorders. They are common, often distressing, and in some cases debilitating, and significantly add to the health care burden. They present with multiple, overlapping symptoms that can often obscure the underlying pathology and can pose significant diagnostic and management dilemmas. A meticulous history and comprehensive digital rectal examination can provide clarity on the diagnosis, appropriate testing, and management of these conditions. Today, with the development of sophisticated diagnostic tools such as high-resolution and high-definition (3-D) anorectal manometry, 3-D anal ultrasonography, magnetic resonance defecography and imaging, and neurophysiological tests such as translumbosacral anorectal magnetic stimulation, it is possible to more accurately define and characterize the underlying structural and functional abnormalities. In this review, we present a succinct update on the latest knowledge with regards to the pathophysiology, diagnosis and management of anal fissure, hemorrhoids, rectal prolapse, intussusception, rectocele, solitary rectal ulcer syndrome, levator ani syndrome, dyssynergic defecation and fecal incontinence.

Clinical presentation and characteristics of pelvic floor myofascial pain in patients presenting with constipation

BACKGROUND

Patients with pelvic floor myofascial pain (PFMP) have puborectalis tenderness on digital rectal examination (DRE). Little is known about its significance to anorectal function in patients presenting with constipation.

AIM

To characterize demographics, clinical characteristics, findings on anorectal manometry (ARM), diagnosis of rectal evacuation disorder (RED), colonic transit [normal (NTC) or slow (STC)], and imaging in constipated patients with PFMP and compare these features to constipation without PFMP.

METHODS

We performed an electronic medical records review of patients with constipation evaluated by a single gastroenterologist between January 2008 and February 2019. Patients with PFMP were compared to controls with constipation but without PFMP (1:2 ratio).

KEY RESULTS

A total of 98 PFMP cases and 196 controls were identified. Constipated patients with PFMP were more likely to have RED [OR 7.59 (3.82-15.09), P < .01]; controls were more likely to have either NTC [OR 4.25 (1.45-12.42), P < .01] or STC [OR 3.57 (1.45-8.78), P < .01]. RED in patients with PFMP is supported by comparison to controls: On DRE, they had increased resting tone [OR 2.25 (1.33-3.83), P < .01] and paradoxical contraction of the puborectalis upon simulated evacuation [OR 3.41 (1.94-6.00), P < .01]; on ARM, they had higher maximum resting pressure (102.9 mmHg vs 90.7 mmHg, P < .01) and lower rectoanal pressure gradient (-39.4 mmHg vs -24.7 mmHg, P < .01).

CONCLUSIONS/INFERENCES

In constipated patients, PFMP is highly associated with RED. Its presence provides a valuable clue regarding the etiology of a patient's constipation; it should be assessed in all patients with constipation and should also be an additional target for management.

New concept for treating urinary incontinence after radical prostatectomy with radiofrequency: phase 1 clinical trial

To describe the clinical response and side effects of radiofrequency treatment in patients with urinary incontinence after radical prostatectomy. This is a phase 1 clinical trial with 10 men up to 65 years of age who had urinary incontinence after radical prostatectomy, post void residual volume < 50 ml verified by ultrasonography, pad test ≥ 1 g, and PSA < 0.2 ng/ml. pad test and self-administered questionnaires were used to assess clinical response. Scales were used to measure treatment satisfaction and improvement in symptoms. Participants underwent five sessions of 2 min of non-ablative endoanal radiofrequency (41 °C). The evaluated co-primary endpoints were urinary incontinence volume and urinary symptoms, analyzed by the Wilcoxon nonparametric test; residual volume, and self-reports to assess safety. The participants' mean age was 57.5 ± 4.9. The initial pad test score was 6.5 g (1.7-50.0) with a final score of 2.0 g (0.0-9.0) (p < 0.01). Ultrasonography showed no alteration of residual volume. A decrease of urinary loss was found in nine patients, three of them showed a complete resolution of urinary loss. A decrease in irritative micturition symptoms was found as well, but no improvement in the quality of life was shown. Regarding treatment satisfaction, two patients were neutral, six satisfied, and two very satisfied. Limitations included pain while the endoanal electrode was inserted. Four patients indicated pain during treatment, but overall results were positive. The reduction of urinary loss and irritative micturition symptoms increased patients' satisfaction scores, without improving their perception of quality of life.

Chronic Constipation

Constipation is a common symptom that may be primary (idiopathic or functional) or associated with a number of disorders or medications. Although most constipation is self-managed by patients, 22% seek health care, mostly to primary care physicians (>50%) and gastroenterologists (14%), resulting in large expenditures for diagnostic testing and treatments. There is strong evidence that stimulant and osmotic laxatives, intestinal secretagogues, and peripherally restricted μ-opiate antagonists are effective and safe; the lattermost drugs are a major advance for managing opioid-induced constipation. Constipation that is refractory to available laxatives should be evaluated for defecatory disorders and slow-transit constipation using studies of anorectal function and colonic transit. Defecatory disorders are often responsive to biofeedback therapies, whereas slow-transit constipation may require surgical intervention in selected patients. Both efficacy and cost should guide the choice of treatment for functional constipation and opiate-induced constipation. Currently, no studies have compared inexpensive laxatives with newer drugs that work by other mechanisms.

Pelvic pain in patients with complex mullerian anomalies including Mayer-Rokitansky-Kuster-Hauser syndrome (MRKH), obstructed hemi-vagina ipsilateral renal anomaly (OHVIRA), and complex cloaca

Caring for patients with congenital pelvic anomalies can be challenging in many ways but one crucial aspect is providing longitudinal into adulthood. Newborns with urinary, intestinal or vaginal obstruction require urgent operations to relieve obstruction followed by multiple reconstructive procedures involving the perineum. Openings are created in the pelvic floor musculature that did not exist in development. Adolescence presents further challenges for these postoperative patients while other diagnoses present for the first time in the peri-pubertal teenage years. Young adults can have new symptoms when they become sexually active and are faced with reproductive decisions. During all of these time periods, optimization of function is of paramount importance and patients who are suffering are not able to participate in school, sports or work. This study evaluates the prevalence of pelvic pain in newborns and adolescents with complex congenital pelvic anomalies, associated factors and possible treatment options.

Pelvic pain rehabilitation

Chronic pelvic pain is defined as persistent painful condition which lasts for at least six months under umbilicus. Numerous factors are blamed for etiopathogenesis, and quality of life of individuals is adversely affected. Chronic pain as well as functional disorders are accompanied to chronic pelvic pain. The treatment and rehabilitation program should be tailored for specific causes, targeting general pain treatment. Consequently, chronic pelvic pain management can be used to propose personalized treatment options and include patient education, behavioral therapy, and a biopsychosocial approach. Interdisciplinary teamwork and collaboration are essential for facilitating patient-centered rehabilitation.

Botox treatment in patients with chronic functional anorectal pain: experiences of a tertiary referral proctology clinic

BACKGROUND

Anorectal pain is a symptom which may have both structural and functional causes, and can, sometimes, develop into a chronic pain syndrome. Functional causes in particular are challenging to treat when conservative treatment measures fail. Botulinum toxin A (BTX-A) can be applied to relax the anal sphincter and/or levator ani muscle to break the vicious circle of pain and contraction. In our tertiary referral proctology clinic, we evaluated the outcome of patients treated with BTX-A for chronic functional anorectal pain.

METHODS

Our electronic database was searched for patients who had BTX-A treatment for chronic functional anorectal pain from 2011 to 2016. All medical data concerning history, treatments, and clinical outcome were retrieved. The clinical outcome (resolution of pain) was scored as good, temporary, or poor.

RESULTS

A total of 113 patients [47 (42%) males; age 51years, SD 13 years, range 18-88 years] with chronic functional anorectal pain were included. The outcome of BTX-A treatment was good in 53 (47%), temporary in 23 (20%), and poor in 37 (33%). To achieve this outcome, 29 (45%) patients needed a single treatment, 11 (44%) a second treatment, and 13 (54%) ≥ 3 treatments.

CONCLUSIONS

Chronic functional anorectal pain can be treated successfully with BTX-A in 47% of patients who fail conservative management. Repeated injections may be needed to ensure complete cure in a subgroup of patients.

Proctalgia and constipation secondary to hypertrophic polyglucosan inclusion body myopathy of the internal anal sphincter: a case report

Background

Hereditary polyglucosan inclusion body myopathy of the internal anal sphincter is a rare cause of proctalgia fugax and constipation. Treatment options are explored.

Case presentation

A 61 year-old Caucasian woman presented with an 18-year history of severe anal pain and constipation. She had no response to medical treatment which included amitriptyline and topically administered diltiazem. Endoscopy revealed no abnormalities, whereas endoanal ultrasound showed an abnormally thick internal anal sphincter (> 5 mm) and anal manometry showed intermittent episodes of very high resting pressures in excess of 200 mmHg that resolved spontaneously after 2 minutes. She had no relief of her symptoms after receiving an injection of botulinum toxin to the internal anal sphincter. She subsequently underwent a lateral internal anal sphincterotomy which led to complete resolution of her symptoms.

Conclusions

Hereditary polyglucosan inclusion body myopathy of the internal anal sphincter should be considered in the differential diagnosis of a patient presenting with severe anal pain and constipation in the absence of an anal fissure or sepsis. If medical therapy with calcium antagonists fails to provide symptom relief, lateral internal sphincterotomy should be considered rather than botulinum toxin injection.

[Specific clinical signs suggestive of endometriosis (excluding adenomyosis) and questionnaires of symptoms, pain and quality of life: CNGOF-HAS Endometriosis Guidelines]

In case of consultation for chronic pelvic pain or suspicion of endometriosis, it is recommended to evaluate the pain (intensity, resonance) and to search out the evocative and localizing symptoms of endometriosis (Grade B). The main symptoms suggestive of endometriosis are: severe dysmenorrhea (NP2), deep dyspareunia (NP2), painful defecation during menstruation (NP2), urinary tract symptoms during menstruation (NP2) and infertility (NP2). In patients with chronic pelvic pain, it is recommended to search deep infiltrating endometriosis in patients with painful defecation during menstruation or severe deep dyspareunia (Grade B). It is recommended to search symptoms suggestive of sensitization in painful patients with endometriosis (Grade B). When suggestive symptoms of endometriosis are present, a directed gynecological examination is recommended, where possible, including examination of the posterior vaginal cul-de-sac (Grade C). In assessing pain intensity or evaluating analgesic effectiveness of a treatment, it is recommended to use a scale to measure the intensity of pain (Grade A). In the management of symptomatic endometriosis, it is recommended to evaluate the quality of life (Grade C).

Use of botulinum A toxin for proctalgia fugax-a case report of successful treatment

Proctalgia fugax is considered as intermittent anal pain of unknown etiology; a variety of treatments have been used, without, however, permanent results. Injection of botulinum A toxin is recently suggested as an alternative option. We present the case of a woman presenting proctalgia fugax that was untreatable through other current forms of treatment. After two administrations of botulinum A toxin, 80 units and 100 units each, the patient remained asymptomatic on 8-month follow-up control. Botulinum A toxin injection can reduce internal anal sphincter pressure, leading to relief of symptoms, and seems a promising option with minimal morbidity in cases on proctalgia fugax that does not respond to other current treatments.

Chronic Pelvic Pain: Assessment, Evaluation, and Objectivation

Chronic Pelvic Pain (CPP) and Chronic Pelvic Pain Syndrome (CPPS) have a significant impact on men and women of reproductive and nonreproductive age, with a considerable burden on overall quality of life (QoL) and on psychological, functional, and behavioural status. Moreover, diagnostic and therapeutic difficulties are remarkable features in many patients. Therefore evaluation, assessment and objectivation tools are often necessary to properly address each patient and consequently his/her clinical needs. Here we review the different tools for pain assessment, evaluation, and objectivation; specific features regarding CPP/CPPS will be highlighted. Also, recent findings disclosed with neuroimaging investigations will be reviewed as they provide new insights into CPP/CPPS pathophysiology and may serve as a tool for CPP assessment and objectivation.

Immunological Mechanisms Underlying Chronic Pelvic Pain and Prostate Inflammation in Chronic Pelvic Pain Syndrome

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is the most common urologic morbidity in men younger than 50 years and is characterized by a diverse range of pain and inflammatory symptoms, both in type and severity, that involve the region of the pelvis, perineum, scrotum, rectum, testes, penis, and lower back. In most patients, pain is accompanied by inflammation in the absence of an invading infectious agent. Since CP/CPPS etiology is still not well established, available therapeutic options for patients are far from satisfactory for either physicians or patients. During the past two decades, chronic inflammation has been deeply explored as the cause of CP/CPPS. In this review article, we summarize the current knowledge regarding immunological mechanisms underlying chronic pelvic pain and prostate inflammation in CP/CPPS. Cumulative evidence obtained from both human disease and animal models indicate that several factors may trigger chronic inflammation in the form of autoimmunity against prostate, fostering chronic prostate recruitment of Th1 cells, and different other leukocytes, including mast cells, which might be the main actors in the consequent development of chronic pelvic pain. Thus, the local inflammatory milieu and the secretion of inflammatory mediators may induce neural sensitization leading to chronic pelvic pain development. Although scientific advances are encouraging, additional studies are urgently needed to establish the relationship between prostatitis development, mast cell recruitment to the prostate, and the precise mechanisms by which they would induce pelvic pain.

Chronic scrotal pain and microsurgical spermatic cord denervation: tricks of the trade

Every practicing urologist encounters patients complaining of chronic scrotal content pain (CSCP). This condition can be equally frustrating for both patients and clinicians as there are no clear treatment guidelines, or pathways, for urologists to follow. As a result, most patients typically seek out multiple providers without improvements in their symptoms. Fortunately, microsurgical spermatic cord denervation (MSCD) is becoming an accepted, reliable and reproducible technique for definitively addressing CSCP in select patients. This manuscript reviews the background, effectiveness and current practice guidelines for scrotal pain in general, and MSCD in particular. Technical insights into how this technique can be performed both safely, and efficaciously, are provided. Finally, the manuscript presents a simple, yet detailed, easy to follow treatment algorithm to aid all urologists in the management of patients presenting with chronic pain.
