Alterations of Prostanoid Expression and Intestinal Epithelial Barrier Functions in Ileus.

INTRODUCTION: Intestinal manipulation (IM)-induced inflammation could contribute to postoperative ileus (POI) pathophysiology via the modulation of prostanoid pathways. To identify the prostanoids involved, we aimed to characterize the profile of prostanoids and their synthesis enzyme expression in a murine model of POI and to determine whether the altered prostanoids could contribute to POI. METHODS: Four or 14 h after IM in mice, gastrointestinal (GI) motility and intestinal epithelial barrier (IEB) permeability were assessed in vivo and ex vivo in Ussing chambers. Using high sensitivity liquid chromatography-tandem mass spectrometry, we characterized the tissue profile of polyunsaturated fatty acid metabolites in our experimental model. Finally, we evaluated in vivo the effects of the prostanoids studied upon IM-induced gut dysfunctions. RESULTS: We first showed that 14 h after IM was significantly faster than jejunal transit at 4 h post-IM, although it remained significantly increased compared to the control. In contrast, we showed that IM-induced inflammation increase in jejunum permeability was similar after four and 14 h. We next showed that expression of prostacyclin synthase and hemopoietic prostaglandin-D synthase mRNA and their products were significantly reduced 14 h after IM as compared to controls. Furthermore, 15-deoxy-delta 12,14-Prostaglandin J2 reduced the IM-induced inflammation increase in IEB permeability but had no effect on GI motility. In contrast, PGI2 increased IM-induced IEB permeability and motility dysfunctions. CONCLUSIONS: Arachidonic acid derivative contributes differentially to GI dysfunction in POI. The decrease of 15-deoxy-delta 12,14-Prostaglandin J2 levels induced by IM could contribute to impaired GI dysfunctions in POI and could be considered as putative therapeutic targets to restore barrier dysfunctions associated with POI.

Evaluation of a scoring system for the detection of central sensitization among women with chronic pelvic pain.

BACKGROUND: Central sensitization is frequently associated with chronic pelvic pain and requires specific management. The pain is described as hypersensitivity to an innocuous stimulus that is both widespread and persistent. However, no study has evaluated if central sensitization can be measured objectively with neurophysiological tests in the pelvic and perineal area to prove this concept in women with chronic pelvic pain. OBJECTIVE: This study aimed to evaluate nociceptive thresholds (primary objective) and spatial and temporal diffusion of pain among women with chronic pelvic pain and high or low scores of central sensitization. STUDY DESIGN: This prospective, assessor-blinded, comparative study compared a cohort of women with chronic pelvic pain and a high (>5/10; n=29) vs low (<5/10; n=24) score of sensitization according to the Convergences PP criteria. Participants underwent a noninvasive bladder sensory test, a rectal barostat test, and a muscular (algometer) and a vulvar (vulvagesiometer) sensory test. Poststimulation pain (minutes), quality of life (Medical Outcomes Study 36-Item Short Form Survey), and psychological state, comprising anxiety (State-Trait Anxiety Inventory), depression (Beck Depression Inventory Short Form), and catastrophizing (Pain Catastrophizing Scale), were assessed. RESULTS: The participants mostly suffered from endometriosis (35.8%), irritable bowel syndrome (35.8%), bladder pain syndrome (32.1%), and vestibulodynia (28.3%). Baseline characteristics were similar. Women with a high sensitization score had more painful diseases diagnosed (2.7±1.3 vs 1.6±0.8; P=.002) and suffered for longer (11±8 vs 6±5 years; P=.028) than participants with a low score. The bladder maximum capacity was equivalent between participants (399±168 vs 465±164 mL; P=.18). However, the pain felt at each cystometric threshold was significantly increased in women with a high sensitization score. No difference was identified for the rectal pain pressure step (29.3±5.5 vs 30.7±6.5 mm Hg; P=.38). Rectal compliance was decreased in women with a high sensitization score with a considerable increase in pain felt. The average of pain pressure thresholds at the 5 vulvar sites tested was decreased in these participants (162.5±90.5 vs 358.7±196.5 g; P=.0003). Similar results were found for the average of the pain pressure thresholds at 6 muscles tested (1.34±0.41 vs 2.63±1.52 kg/m2; P=.0002). A longer period was needed for patients with high sensitization score to obtain a VAS <3 out of 10 after the stimulation of the bladder (4.52±5.26 vs 1.27±2.96 minutes; P=.01), the rectum (3.75±3.81 vs 1.19±1.23 minutes; P=.009), and the muscles (1.46±1.69 vs 0.64±0.40 minutes; P=.002). The psychological state was equivalent between groups. No association was found between the sensory thresholds and the psychological state results. The physical component of the quality of life score was reduced in women with high sensitization score (P=.0005), with no difference in the mental component. CONCLUSION: Using neurophysiological tests, this study showed that there are objective elements to assess for the presence of central sensitization, independently of psychological factors.

Preoperative Mechanical Bowel Preparation for Gynecologic Surgeries: A Systematic Review with Meta-analysis.

OBJECTIVE: To assess the efficacy and safety of mechanical bowel preparation (MBP) before benign laparoscopic or vaginal gynecologic surgeries. DATA SOURCES: Database searches of MEDLINE (PubMed), Embase (OVID), Cochrane Central Register of Controlled Trials, and Web of Sciences and citations and reference lists published up to December 2021. METHODS OF STUDY SELECTION: Randomized clinical trials in any language comparing MBP with no preparation were included. Two reviewers independently screened 925 records and extracted data from 12 selected articles and assessed the risk of bias with the Cochrane risk-of-bias tool for randomized trials tool. A random-effects model was used for the analysis. Surgeon findings (surgical field view, quality of bowel handling and bowel preparation), operative outcomes (blood loss, operative time, length of stay, surgical site infection), and patient's preoperative symptoms and satisfaction were collected. TABULATION, INTEGRATION, AND RESULTS: Thirteen studies (1715 patients) assessing oral and rectal preparations before laparoscopic and vaginal gynecologic surgeries were included. No significant differences were observed with or without MBP on surgical field view (primary outcome, risk ratio [RR] 1.01, 95% confidence interval [CI] 0.97-1.05, p = .66, I2 = 0%), bowel handling (RR 1.01, 95% CI 0.95-1.08, p = .78, I2 = 67%), or bowel preparation. In addition, there were no statistically significant differences in perioperative findings. MBP was associated with increased pain (mean difference [MD] 11.62[2.80-20.44], I2 = 76, p = .01), weakness (MD 10.73[0.60-20.87], I2 = 94, p = .04), hunger (MD 17.52 [8.04-27.00], I2 = 83, p = .0003), insomnia (MD 10.13[0.57-19.68], I2 = 82, p = .04), and lower satisfaction (RR 0.68, 95% CI 0.53-0.87, I2 = 76%, p = .002) compared with controls. CONCLUSIONS: MBP has not been associated with improved surgical field view, bowel handling, or operative outcome. However, in view of the adverse effects induced, its routine use before benign gynecologic surgeries should be abandoned.

[Pelvic exam in gynecology and obstetrics: Guidelines for clinical practice]. / Examen pelvien en gynécologie et obstétrique : recommandations pour la pratique clinique.

OBJECTIVE: To provide guidelines for the pelvic clinical exam in gynecology and obstetrics. MATERIAL AND METHODS: A multidisciplinary experts consensus committee of 45 experts was formed, including representatives of patients' associations and users of the health system. The entire guidelines process was conducted independently of any funding. The authors were advised to follow the rules of the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) system to guide assessment of quality of evidence. The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasized. METHODS: The committee studied 40 questions within 4 fields for symptomatic or asymptomatic women (emergency conditions, gynecological consultation, gynecological diseases, obstetrics, and pregnancy). Each question was formulated in a PICO (Patients, Intervention, Comparison, Outcome) format and the evidence profiles were produced. The literature review and recommendations were made according to the GRADE® methodology. RESULTS: The experts' synthesis work and the application of the GRADE method resulted in 27 recommendations. Among the formalized recommendations, 17 present a strong agreement, 7 a weak agreement and 3 an expert consensus agreement. Thirteen questions resulted in an absence of recommendation due to lack of evidence in the literature. CONCLUSIONS: The need to perform clinical examination in gynecological and obstetrics patients was specified in 27 pre-defined situations based on scientific evidence. More research is required to investigate the benefit in other cases.

Robot-assisted laparoscopy repair of uterine isthmocele: A two-center observational study.

OBJECTIVE: To analyze outcomes and postoperative complications in patients undergoing robot-assisted isthmocele repair. METHOD: This retrospective cohort study included 33 patients who had robot-assisted laparoscopic surgical management of an isthmocele between September 2013 and August 2020 in two French university hospitals. All charts were reviewed to identify patient characteristics, preoperative and postoperative anatomical findings, complications, and postoperative fertility and symptoms. Patients who had undergone this procedure were asked to complete a telephone questionnaire about their treatment satisfaction and symptoms. RESULTS: The isthmocele was discovered most often as a result of subfertility (57.6%), but also ectopic pregnancy (18.2%), pelvic pain (15.2%), and postmenstrual bleeding (9.1%). Robot-assisted repair of the isthmocele significantly improved myometrial thickness (from 1.55 mm before surgery to 4.26 mm after surgery [mean difference 2.71; 95% confidence interval, 1.91-3.51], P = 0.0005). Among 20 patients who still desired a child after surgery, 15 became pregnant and 14 had full-term live births. Among the nine patients who had surgery for disabling symptoms, five had no persistent symptoms, three reported global improvement, and one had the same gynecologic discomfort. Seventeen patients agreed to complete the questionnaires (51.5%), and all stated that they would choose to have this surgery again. CONCLUSION: Robot-assisted repair of an isthmocele is a viable minimally invasive procedure.

Ropivacaine perineal infiltration for postpartum pain management in episiotomy repair: a double-blind, randomised, placebo-controlled trial.

OBJECTIVE: To investigate whether perineal infiltration of ropivacaine after episiotomy would decrease the incidence of postpartum pain compared with placebo. DESIGN: Two-centre, double-blind, randomised, controlled trial. SETTING: Two French maternity units, October 2017 to April 2020. POPULATION: 272 women undergoing epidural analgesia with vaginal singleton delivery and mediolateral episiotomy at term (≥37 weeks) were randomly allocated perineal infiltration of ropivacaine (n = 135) or placebo (n = 137) in a 1:1 ratio before episiotomy repair. METHODS: Patients were followed at short term (12, 24, 48 h), mid-term (day 7) and long-term (3 and 6 months). MAIN OUTCOME MEASURES: The primary outcome was the rate of perineal pain, defined by a Numerical Pain Rating Scale (NPRS) exceeding 3/10, in the mid-term (day 7) postpartum period. Secondary outcomes were perineal pain (NPRS) and analgesic intake, quality of life (SF-36), postpartum depression (EPDS), pain neuropathic component (DN4) and sexual health (FSFI). RESULTS: Perineal pain occurred to an equal extent in the ropivacaine and placebo groups at day 7 (34.2% versus 30.4%, odds ratio 1.1, 95% confidence interval 0.7-1.8, p = 0.63). Similar results were recorded in the short and long term. High rates of dyspareunia and postpartum depression were documented in both groups. No differences were highlighted between the groups in terms of analgesic intake, adverse events, pain neuropathic component and postpartum quality of life. CONCLUSIONS: This study did not demonstrate any benefit of ropivacaine infiltration over placebo.

Translation and Cultural Validation of the WERF EPHect Endometriosis Patient Questionnaire into Canadian French.

OBJECTIVE: To produce a culturally validated Canadian French version of the Standard EPHect Endometriosis Patient Questionnaire (EPQ-S) from the World Endometriosis Research Foundation (WERF). METHODS: We studied 17 premenopausal women who were seen for pelvic pain symptoms or suspicion of endometriosis at the gynaecology clinic of the CHU de Québec - Université Laval (Québec City, Canada). Participants completed the French language version of the questionnaire at their first visit, and the validation took place about 1 week later. RESULTS: All 22 of the invited women agreed to participate, of whom 17 were reached for the validation. The mean age of participants was 38.9 years, and 15 (88%) had a confirmed diagnosis of endometriosis. Fourteen participants (82%) found the questionnaire clear and relevant. The average length of time to complete the questionnaire was 36.25 ± 10.8 minutes. The validation process resulted in the addition of lines at the end of each section to allow space for specific comments and some clarifications with respect to timelines. CONCLUSION: This study validated a Canadian French version of the EPHect questionnaire. With such validation studies, differences in language and culture will no longer be a barrier to large national and international studies on endometriosis, leading to high-quality research and breakthroughs for millions of individuals living with this disease.

National survey of surgical practices: Sacropexy in France in 2019.

INTRODUCTION AND HYPOTHESIS: Sacropexy is a reference surgical treatment for pelvic organ prolapse in women. The great variability in surgical techniques for this procedure is a source of bias that complicates analysis of the results of trials assessing it. Using the French guidelines issued in 2016 by the SCGP, AFU, SIFUD-PP, and CNGOF as a reference, we sought to inventory the surgical practices of the surgeons who perform these procedures. METHODS: In November 2018, a questionnaire about the technical aspects of this procedure was distributed by email to the French physicians performing it. It was distributed to members of several professional societies (CNGOF, SCGP, and SIFUD) and to gynecologists practicing in clinics owned by the ELSAN group. RESULTS: Of the 273 responders, 92% reported that they perform most operations laparoscopically. Overall, 83% of gynecologic surgeons used polypropylene prostheses (mesh); 38% routinely placed a posterior mesh, while the rest did so only in cases of clinical rectocele with anorectal symptoms. A concomitant hysterectomy was performed by 51% of respondents when the uterus was bulky and/or associated with substantial uterine prolapse. Finally, half the surgeons suggested the placement of a suburethral sling for women with stress urinary incontinence. CONCLUSIONS: Although practices are largely consistent with the most recent guidelines, surgical techniques vary widely between surgeons, both in France and internationally.

Diastasis of the rectus abdominis muscles in postpartum: Concordance of patient and clinician evaluations, prevalence, associated pelvic floor symptoms and quality of life.

OBJECTIVES: The main objective was to assess the reliability of the patient's measurement of diastasis. The secondary aims were the estimation postpartum diastasis prevalence, of diastasis-associated pelvic floor symptoms and quality of life immediately after childbirth and at 3-6 months postpartum. STUDY DESIGN: Using a prospective observational design, women who gave birth in a French university hospital were eligible. After a learning phase, both clinician and patient conducted a clinical evaluation of diastasis. Then, patients were asked to complete the HerQLes, the FPFQ and a general questionnaire. Three to 6 months later, patients completed the same questionnaires online and performed a clinical evaluation of diastasis at home, as learned previously. RESULTS: Of 253 patients included in the study, 139 (54.9 %) completed the questionnaires at 3-6 months of follow-up. There was good correlation between clinician and patient evaluations of diastasis (kappa coefficient 0.76 [95 % CI, 0.5-0.7]). Immediately after childbirth, 210 (83 %) of the women presented diastasis including 116/210 (55 %) cases of severe diastasis and 51 (42 %) of those had persistent diastasis at 3-6 months of follow-up. Cesarean section (p = 0.05) and multiparity (p = 0.04) were factors of persistent diastasis. Severe diastasis had a significant impact on quality of life (HerQLes score) at birth (p = 0.001) and at 3-6 months (p = 0.01), but no effect on pelvic floor symptoms according the FPFQ. The occurrence and severity of diastasis did not significantly impact lumbar or pubic symphysis pain. Furthermore, the aesthetic discomfort felt by patients was significantly increased by the presence of diastasis on a numerical scale at 3-6 months (p = 0.03). CONCLUSION: Good agreement between clinician and patient evaluations of postpartum diastasis indicated that the evaluation method is reliable. Persistent diastasis was associated with impaired quality of life.

Ropivacaine 75 mg versus placebo in perineal infiltration for analgesic efficacy at mid- and long-term for episiotomy repair in postpartum women - the ROPISIO study: a two-center, randomized, double-blind, placebo-controlled trials.

BACKGROUND: Perineal pain due to episiotomy is commonly reported and can be severe enough to disturb the mother-infant dyad during the postpartum period. Its incidence at day 7 postpartum varies from 63% to 74%. Recent studies have investigated the analgesic efficacy of perineal infiltration of ropivacaine after episiotomy but have only focused on the immediate postpartum period (at 24 and 48 h after birth). Large, adequately powered, multicenter, randomized controlled trials are required to evaluate the impact of ropivacaine infiltration on perineal pain and mid- and long-term quality of life before the widespread use of ropivacaine to prevent perineal pain after episiotomy can be recommended. METHODS/DESIGN: The ROPISIO study is a two-center, randomized, double-blind, placebo-controlled trial being conducted in La Roche sur Yon and Nantes, France. It will involve 272 women with vaginal singleton delivery and mediolateral episiotomy at term (≥ 37 weeks). Perineal infiltration (ropivacaine 75 mg or placebo) will be administrated just after vaginal birth and before episiotomy repair. The primary outcome will be the analgesic efficacy at day 7 postpartum (midterm), defined by the Numeric Pain Rating Scale (NPRS) strictly superior to 3/10 on the perineal repair area. Secondary outcomes will be the analgesic efficacy (NPRS) and the impact of pain on daily behavior, on the quality of life (36-item Short Form Health Survey), on the occurrence of symptoms of postpartum depression (Edinburgh Postnatal Depression Scale), and on sexual health (Female Sexual Function Index) at 3 and 6 months (long-term) using validated online questionnaires. This study will have 90% power to show approximately 30% relative risk reduction in the incidence of perineal pain at day 7, from 70.0% to 50.0%. DISCUSSION: Ropivacaine is a promising candidate drug, inexpensive, and easy to administer, and it would be suitable to include in the routine management of deliveries in labor ward. This study will investigate if perineal ropivacaine infiltration just after birth can reduce mid- and long-term postpartum pain and increase quality of life in women with mediolateral episiotomy. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03084549. Registered on 14 April 2017.

Description and classification of postpartum chronic pain: A multicentric prospective study.

INTRODUCTION: To classify persistent perineal and pelvic postpartum pain using the classification usually employed in chronic pelvic pain. MATERIAL AND METHOD: Prospective observational study including all women who have consulted an algologist or gynecologist at one of the six French centers for a chronic pain (superior or equal to 3 months) spontaneous linked by the mother with her childbirth were included. During semi-directed interviews, a questionnaire regarding sociodemographic factors and detailed questions about pain were collected. Then, pelvic and perineal pain were classified into 7 pain syndromes: pelvic sensitization (Convergences PP criteria), complex regional pain syndrome (Budapest criteria), pudendal or cluneal neuralgia (Nantes criteria), neuroma, thoraco-lumbar junction syndrome, myofascial pain (muscle trigger zone), fibromyalgia (American College of Rheumatology criteria). The principal objective of this study is to assess the prevalence of each painful disorder. The secondary aims were the description of socio-demographic factors and clinical characteristics of this population, identify the related symptoms and the impact on daily function associated with the chronic pelvic or perineal postpartum pain. RESULTS: 40 women with chronic pelvic or perineal pain spontaneously linked with childbirth were included. 78 % experienced pain for more than 12 months. A large majority had a vaginal birth (95 %) with perineal suture (90 %) and severe acute pain within the first week postpartum (62 %). Postpartum pain impacted participant's sexual activity (80 %), micturition (28 %) and defecation (38 %). In the sample, 17 cases of neuroma, 6 patients with pudendal or cluneal neuralgia, 13 patients with pelvic sensitization and 2 cases of fibromyalgia were identified. Complex regional pain syndrome was diagnosed in 8 patients, and myofascial pain in 11 women, and only 1 patient had thoraco-lumbar junction syndrome. Neuropathic pain was found in 31 participants (77.5 %) according to DN4 criteria. DISCUSSION: The classification scheme proposed in this study may be a very useful tool to investigate postpartum pelvic and perineal pain and to propose a treatment.

Hospital care pathway of women treated for Bartholin's gland abscess and budget impact analysis of outpatient management: A national hospital database analysis.

INTRODUCTION: Bartholin's gland abscesses cause severe pain and are a source of frequent emergency room visits. The most widespread treatment in France is incision-drainage during hospitalisation. A Word catheter, whose efficiency and safety would be identical, could be used without the need for hospitalisation, thus reducing the costs of Bartholin's gland abscess management. DESIGN: Retrospective cohort study. SETTING: French hospital (PMSI) database 2016-2017. POPULATION: 3539 women with Bartholin's gland abscess. METHOD: From the PMSI database, we identified the population that was treated for incision-drainage of a Bartholin's gland abscess in 2016. We also looked for secondary hospitalisations occurring within 12 months of initial treatment of Bartholin's gland abscess using 2016 and 2017 PMSI database data. MAIN OUTCOME(S): The identified population was described in terms of age, hospitalisation, length of stay and readmissions within 12 months and provided a 5-year budget impact analysis of the use of the Word catheter in France from a National Health Insurance perspective. RESULTS: In 2016, 3539 women (36 +/- 11.8 years) were hospitalised for 3646 incisions of the major vestibular gland linked to a Bartholin's gland abscess. 11.38 % (403/3,539) underwent at least one new Bartholin's gland procedure during the following year. The use of the Word catheter would allow potential savings over 5 years of €7.4 million. CONCLUSION: The use of the Word catheter could be cost-saving. These results must be validated by a clinical research step evaluating efficiency in the French context, comparing the Word catheter and incision-drainage side-by-side.

[Impact of the diastasis of the rectus abdominis muscles on the pelvic-perineal symptoms: Review of the literature]. / Impact du diastasis des muscles droits de l'abdomen sur les symptômes pelvi-périnéaux : revue de la littérature.

INTRODUCTION: The diastasis of the rectus abdominis muscles is common during pregnancy and post-partum. OBJECTIVE: To determine the prevalence of this pathology, methods of diagnosis, association with pelvic-perineal disorders and therapies that may be proposed. METHODS: Review of Pubmed, Medline, Embase and Cochrane literature using the following words and MeSH: diastasis, diastasis and pregnancy, diastasis of the rectus abdominis muscle, increase of the inter-recti distance. RESULTS: Among the 124 articles found, 61 were selected. Ultrasound seems to be the exam of choice both in terms of feasibility and reproducibility for the diagnosis of this pathology (intra-class correlation coefficients (ICC) high 0.81 to 0.94). The risk factors identified vary from one study to another: heavy load bearing (OR=2.18 (95 % CI 1.05 to 4.52) P=0.04), weight gain. Studies are discordant regarding the association between diastasis and low back pain (RR=1.39 (95 % CI 0.91-2.14), P=0.17), urinary incontinence (RR=0.86 (95 % CI 0.55-1.33) P>0.65) and prolapse (OR=2.25 (95 % CI 1.51-3.37) P<0.001), but the diastasis seems to play a role in the alteration of the quality of life for these patients. CONCLUSION: Knowledge about risk factors, consequences of diastasis and management is still limited today. It is therefore necessary to establish prospective studies on larger numbers in order to improve knowledge on the diastasis of the rectus abdominis muscles.

Surgical management of Bartholin cysts and abscesses in French university hospitals.

OBJECTIVES: To assess the methods used to manage Bartholin gland abscesses and cysts in French university hospitals. METHOD: Data for this descriptive, cross-sectional study with self-reported data were collected between January and March 2018 by an online questionnaire. The 11 items of the questionnaire assessed the surgical techniques known and used, the type of hospitalization, and the non-surgical management to treat Bartholin gland abscesses and cysts. RESULTS: Overall, 116 obstetrics-gynecology residents responded to the online questionnaire. The three best-known techniques were incision and drainage, marsupialization, and excision of the Bartholin gland. Only 3% of the physicians knew about other techniques. Most participants reported that their unit treated 2-6 Bartholin gland abscesses monthly and fewer than 2 cysts. The most frequent treatment for abscess was incision-drainage (87%), followed by marsupialization (13%). The most widely used treatment for the cysts was gland excision (68.5%) followed by marsupialization (22.5%). In both cases, management generally took place on an outpatient basis (92.9%). CONCLUSION: This study showed that 87% of the respondents used incision-drainage for Bartholin gland abscesses, although the recurrence and complication rates of this technique have never been evaluated.

Pudendal Neuralgia Due to Pudendal Nerve Entrapment: Warning Signs Observed in Two Cases and Review of the Literature.

Pudendal neuralgia is a chronic neuropathic pelvic pain that is often misdiagnosed and inappropriately treated. The Nantes criteria provide a basis for the diagnosis of pudendal neuralgia due to pudendal nerve entrapment. The 5 essential diagnostic criteria are pain situated in the anatomical territory of the pudendal nerve, worsened by sitting, the patient is not woken at night by the pain, and no objective sensory loss is detected on clinical examination. The fifth criterion is a positive pudendal nerve block. We have also clarified a number of complementary diagnostic criteria and several exclusion criteria that make the diagnosis unlikely. When pudendal neuralgia due to pudendal nerve entrapment is diagnosed according to the Nantes criteria, no further investigation is required and medical or surgical treatment can be proposed. Nevertheless, a number of warning signs suggesting other possible causes of pudendal neuralgia must not be overlooked. These warning signs (red flags) are waking up at night, excessively neuropathic nature of the pain (for example, associated with hypoesthesia), specifically pinpointed pain, which can suggest neuroma and pain associated with neurological deficit. In these atypical presentations, the diagnosis of pain due to pudendal nerve entrapment should be reconsidered and a radiological examination should be performed. The 2 cases described in this report (tumor compression of the pudendal nerve) illustrate the need to recognize atypical pudendal neuralgia and clarify the role of pelvic magnetic resonance imaging (MRI), as MRI provides very valuable information for the evaluation of diseases involving the ischiorectal fossa. The presence of red flags must be investigated in all cases of pudendal neuralgia to avoid missing pudendal neuralgia secondary to a mechanism other than nerve entrapment.
