Chronic pelvic pain affects 15% of women. Our objective was to evaluate empiric laparoscopic inguinal exploration and mesh placement in this population.
Retrospective cohort with follow-up questionnaire of women with lateralizing chronic pelvic pain (right or left), ipsilateral inguinal tenderness on pelvic examination, no clinical hernia on abdominal examination, and ipsilateral empiric laparoscopic inguinal exploration with mesh placement (2003-2009). Primary outcome was pain level at the last postoperative visit. Secondary outcomes were pain level and SF-36 scores from the follow-up questionnaire.
Forty-eight cases met the study criteria. Surgery was done empirically for all patients, with only 7 patients (15%) found to have an ipsilateral patent processus vaginalis (shallow peritoneal dimple or a deeper defect (occult hernia)). Of 43 cases informative for the primary outcome, there was pain improvement in 15 patients (35%); pain improvement then return of the pain in 18 patients (42%); and pain unchanged in 9 patients (21%) and worse in 1 patient (2%). Improvement in pain was associated with a positive Carnett's test in the ipsilateral abdominal lower quadrant (P = .024). Thirteen patients returned the questionnaire (27%), and the pain was now described as improved in 9 patients (69%), unchanged in 4 patients (31%), and worse in none. Three SF-36 subscales showed improvement (physical functioning, social functioning, and pain).
In select women with chronic pelvic pain, empiric laparoscopic inguinal exploration and mesh placement results in moderate improvement in outcome. A positive Carnett's test in the ipsilateral abdominal lower quadrant is a predictor of better outcome.

To characterize differences between individuals with and without mid-cycle pain in a registry cohort with endometriosis. Prospective analysis of data from the Endometriosis Pelvic Pain Interdisciplinary Cohort Data Registry (Clinicaltrials.gov #NCT02911090) at a tertiary referral center in Western Canada. Three hundred forty-five individuals aged 18-49 years who: (1) had at least one episode of menstrual bleeding in the last 3 months, (2) attended a baseline initial visit, and (3) subsequently had surgery with histological confirmation of endometriosis between January 2018 and December 2023. Exclusion criteria included (1) previous hysterectomy; (2) hormonal suppressive therapy use in the last 3 months; and (3) missing data on mid-cycle pain, history of hormonal therapy use, or menstrual cycle regularity. N/A. Mid-cycle pain in the last month versus No mid-cycle pain in the last month. Of the 345 participants, 67% (n = 232) reported mid-cycle pain in the last month. Mid-cycle pain in the last month was significantly associated with higher mean Central Sensitization Inventory score (48 ± 17 versus 36 ± 16, p < 0.001) and more months of prior hormonal suppressive therapy use (58 [14-120] versus 26 [0-109], p = 0.012). Abnormal anatomy at the time of surgery (e.g., endometrioma, ovarian adhesions) was not associated with mid-cycle pain in the last month. In this endometriosis cohort at a tertiary referral center, most participants reported mid-cycle pain in the last month, which was associated with central sensitization but was not clearly related to endometriosis anatomical distortion.

Do quantitative urinary hormone measurements on the Mira monitor predict and confirm ovulation accurately compared with ultrasound in women with regular menstrual cycles? Do Mira urine hormones correlate with serum hormones? This was a prospective, single-centre, blinded diagnostic accuracy study with 52 women aged 19-44 years with regular cycles (24-38 days) who tracked 153 cycles over 18 months. Daily first-morning urine was tested with the Mira monitor for follicle stimulating hormone (FSH), oestrone-3-glucuronide (E13G), luteinizing hormone (LH) and pregnanediol glucuronide (PDG). Serial transvaginal ultrasounds (890 scans) confirmed the day of ovulation. Serum hormones were measured twice per cycle. The 121 ovulatory cycles from 49 participants with sufficient index test and reference standard data were included in the final analysis. The Mira LH peak day strongly predicted ultrasound-confirmed ovulation (R² = 0.96, P < 0.001; intraclass correlation coefficient = 0.971), with 96% of ovulations occurring within ±1 day. The Mira PDG increase was also strongly associated with ultrasound-confirmed day of ovulation (R² = 0.87, P < 0.001). First-morning urine hormones were significantly associated with serum hormones when collected within 90 min (LH: R² = 0.92; E13G: R² = 0.73; R² = 0.61; R² = 0.75). Anovulatory cycles were identified in 11% of regularly cycling participants. Quantitative urinary hormone monitoring with the Mira monitor provides accurate prediction and confirmation of ovulation, with strong urine-serum associations supporting reduced reliance on serial serum draws in select patients. These findings support clinical adoption of quantitative urinary fertility monitoring.

To assess the impact of the COVID-19 pandemic on reproductive outcomes in patients with recurrent pregnancy loss (RPL) and the influence of material and social deprivation on these outcomes. This retrospective cohort study included RPL patients seen at a specialized clinic between March 1, 2018, and February 28, 2022. Patients were categorized into two groups based on care period: pre-pandemic (March 1, 2018-February 29, 2020) and pandemic (March 1, 2020-February 28, 2022). Cumulative probabilities of birth were estimated using the cumulative incidence function within a competing risk framework, treating pregnancy loss as a competing event. Fine and Gray regression models calculated sub-distribution hazard ratio (sHR) of birth. 544 patients were included in the study, with 255 in the pre-pandemic group and 289 in the pandemic group. Individuals in the pandemic group were less likely to achieve pregnancy than those in the pre-pandemic group (relative risk = 0.50, 95% confidence interval [CI] 0.39 - 0.66). Among those who conceived, the cumulative probability of live birth was 0.77 in both groups. Relative to individuals residing in high-social deprivation neighborhoods, those living in moderately deprived areas had higher sub-distribution hazards of live birth (adjusted sHR = 1.97, 95% CI 1.25 - 3.10; P = 0.003). Within specialized RPL care and a universal maternity care system, pregnancy rates were lower during the first two years of the COVID-19 pandemic. However, among those who conceived, the probability of achieving a live birth remained similar between the pre-pandemic and pandemic periods.

Does formation of the corpus luteum help to identify the day of ovulation on ultrasound when follicular collapse is missed, and how reliable are sonographers versus a review panel in identifying the day of ovulation on ultrasound? Sonographers in a clinic in Canada performed serial endovaginal ultrasound scans (six to eight per cycle) to identify the day of ovulation in regularly cycling women (n = 40) who were followed for one to five cycles (n = 85). The day of ovulation was identified by: (i) identification of the dominant follicle; (ii) disappearance of the dominant follicle; and (iii) identification and dating of the corpus luteum. The main outcome measures were inter-rater reliability between two sonographers, and Bland-Altman agreement between the supervising sonographer and a panel that reviewed each scan to identify the day of ovulation. Of the 85 menstrual cycles reviewed, two cycles did not have sufficient data to date ovulation, one cycle showed an incidental dermoid cyst, and 11 cycles showed anovulatory patterns. This left a total of 71 cycles (84%) for which intra-rater reliability between two sonographers for identifying the day of ovulation was high (intraclass correlation coefficient = 0.99, P < 0.0001), and Bland-Altman agreement showed no significant difference in the estimated day of ovulation between the supervising sonographer and the panel (t = -0.28, P = 0.78). Corpus luteum criteria were necessary to help identify the day of ovulation in 14 of 71 cycles (20%). The estimated day of ovulation can be determined reliably on ultrasound by trained sonographers using collapse of the dominant follicle and formation of the corpus luteum based on six to eight scans per cycle.

Published studies relating to the usefulness of diagnostic and operative laparoscopy in women with chronic pelvic pain (CPP) were reviewed. This revealed that approximately 40 per cent of all laparoscopies were done for CPP. However, the definition of CPP was found to be nebulous and inconsistent, and that muddled definitive conclusions about patient diagnoses and treatments. The following definition of CPP was proposed: nonmenstrual pain of 3 or more months duration that localizes to the anatomic pelvis and is severe enough to cause functional disability and require medical or surgical treatment. A survey of published reports showed laparoscopically diagnosable abnormalities in 61 per cent of patients, compared with abnormalities in 28 per cent of women without CPP. Studies in adolescents were also reviewed and showed that adolescents with CPP also had significant laparoscopically diagnosed abnormalities, with 78 per cent showing some pathology, especially endometriosis (40 per cent). Endometriosis, pelvic adhesions, chronic pelvic inflammatory disease, and ovarian cysts were the diagnoses most commonly made via laparoscopy in CPP patients. The potential roles of each of these abnormalities in CPP were discussed, as well as the results of laparoscopic treatment of each disease. Laparoscopy was also found to have a limited role in women with CPP after hysterectomy or bilateral salpingo-oophorectomy, with usefulness in diagnosing and treating adhesions and residual ovary syndrome, although its role in ovarian remnant syndrome was uncertain. Overall, the data showed that less than 50 per cent of women with CPP were helped by diagnostic and operative laparoscopy, stressing the need for both physicians and patients to recognize that laparoscopy is neither the ultimate evaluation nor the panacea for CPP.

To track the severity and location of pelvic pain associated with endometriosis throughout the reproductive-age years and to evaluate the association between these pain parameters and the stage of disease. Historical prospective study. Tertiary care center. PATIENT(S): Forty-eight women with endoscopically staged endometriosis and chronic pelvic pain who had undergone medical and/or conservative surgical therapy. INTERVENTION(S): Each participant was administered a questionnaire that included a determination of the severity and location of her pain. MAIN OUTCOME MEASURE(S): The stage of disease, the area of the pelvis that contained the bulk of disease, the severity of pain, and the location of the most severe pain were recorded. RESULT(S): The mean duration from the initial diagnosis until follow-up was 15.7 +/- 3.1 years, Twenty-one (43.8%) subjects denied any symptoms of pain on follow-up evaluation. Of the 27 patients with persistent pain, 21 (78%) identified the location of their most severe pain as being the same as at initial diagnosis. The stage of disease at initial diagnosis was significantly associated with a higher degree of pain at follow-up. CONCLUSION(S): These data suggest that endometriosis-associated chronic pelvic pain commonly persists throughout the reproductive years and that endometriosis stage is directly related to the persistence of pelvic pain.

Chronic pelvic pain affects ∼15% of women, and presents a challenging problem for gynecologists due to its complex etiology involving multiple comorbidities. Thus, an interdisciplinary approach has been proposed for chronic pelvic pain, where these multifactorial comorbidities can be addressed by different interventions at a single integrated center. Moreover, while cross-sectional studies can provide some insight into the association between these comorbidities and chronic pelvic pain severity, prospective longitudinal cohorts can identify comorbidities associated with changes in chronic pelvic pain severity over time. We sought to describe trends and factors associated with chronic pelvic pain severity over a 1-year prospective cohort at an interdisciplinary center, with a focus on the role of comorbidities and controlling for baseline pain, demographic factors, and treatment effects. This was a prospective 1-year cohort study at an interdisciplinary tertiary referral center for pelvic pain and endometriosis, which provides minimally invasive surgery, medical management, pain education, physiotherapy, and psychological therapies. Exclusion criteria included menopause or age >50 years. Sample size was 296 (57% response rate at 1 year; 296/525). Primary outcome was chronic pelvic pain severity at 1 year on an 11-point numeric rating scale (0-10), which was categorized for ordinal regression (none-mild 0-3, moderate 4-6, severe 7-10). Secondary outcomes included functional quality of life and health utilization. Baseline comorbidities were endometriosis, irritable bowel syndrome, painful bladder syndrome, abdominal wall pain, pelvic floor myalgia, and validated questionnaires for depression, anxiety, and catastrophizing. Multivariable ordinal regression was used to identify baseline comorbidities associated with the primary outcome at 1 year. Chronic pelvic pain severity decreased by a median 2 points from baseline to 1 year (6/10-4/10, P < .001). There was also an improvement in functional quality of life (42-29% on the pain subscale of the Endometriosis Health Profile-30, P < .001), and a reduction in subjects requiring a physician visit (73-36%, P < .001) or emergency visit (24-11%, P < .001) in the last 3 months. On multivariable ordinal regression for the primary outcome, chronic pelvic pain severity at 1 year was independently associated with a higher score on the Pain Catastrophizing Scale at baseline (odds ratio, 1.10; 95% confidence interval, 1.00-1.21, P = .04), controlling for baseline pain, treatment effects (surgery), age, and referral status. Improvements in chronic pelvic pain severity, quality of life, and health care utilization were observed in a 1-year cohort in an interdisciplinary setting. Higher pain catastrophizing at baseline was associated with greater chronic pelvic pain severity at 1 year. Consideration should be given to stratifying pelvic pain patients by catastrophizing level (rumination, magnification, helplessness) in research studies and in clinical practice.

To document the abnormal findings at hysteroscopy and laparoscopy in patients with chromic pelvic pain. Prospective evaluation at surgery of women treated consecutively between January 1, 1991, and December 30, 1992. A private practice. One hundred forty-one women with pelvic pain (average age 35 yrs). Laparoscopy was performed in all patients, and hysteroscopy in all but one, who had had a hysterectomy. Endometrial and endocervical biopsies were performed. MAIN In 42 (30%) of 140 patients with a primary diagnosis of chronic pelvic pain hysteroscopic evaluation with endometrial and endocervical biopsies revealed an abnormality. Findings at hysteroscopy included leiomyomas in 25 patients (18%), intrauterine polyps in 9 (6.4%), and cervical stenosis in 4 (2.9%). Three women (2.1%) had intrauterine scarring and one (0.7%) had a bicornuate uterus. Endometrial biopsies showed adenomatous hyperplasia with atypia, and cystic hyperplasia in one patient each. Endocervical biopsies revealed cervical dysplasia in four women (2. 89%). An abnormal finding was documented on laparoscopic examination in all 141 patients. These included endometriosis in 113 patients (80%), adhesions in 67 (48%), leiomyomas in 59 (42%), and enlarged globular uterus in 34 (24%). In addition, appendiceal abnormalities were present in three women (2.1%) and hernia in two (1.4%). Hysteroscopic abnormalities were found in 30% and laparoscopic abnormalities in 100% of patients who had a primary diagnosis of chronic pelvic pain.
