Abstract
INTRODUCTION AND HYPOTHESIS We aimed to investigate whether the Manchester procedure affects the risk and prognosis of endometrial cancer. METHODS All Danish residents have a personal number permitting linkage of nationwide registers on the individual level enabling epidemiological studies with lifelong follow-up. We performed a nationwide historical cohort study including Danish women born before 2000 undergoing the Manchester procedure (N = 23,935) during 1977-2018. We included women undergoing anterior colporrhaphy as a reference group (N = 51,008) because of comparable inclination to consult a doctor and clinical similarities. Main outcomes were the number of women diagnosed with endometrial cancer, the stage of endometrial cancer at time of diagnosis, and cancer-specific and overall mortality. We followed the cohort until endometrial cancer/death/emigration/hysterectomy/31 December 2018. We performed chi-square test for trend to compare the diagnostic stage and Cox regressions to analyze the risk of endometrial cancer and mortality. The models were adjusted for age, calendar year, income level, and parity. RESULTS During follow-up (median 13 years), 271 (1.13%) women were diagnosed with endometrial cancer after the Manchester procedure and 520 (1.05%) after anterior colporrhaphy. The adjusted hazard ratio (HR) for endometrial cancer was 1.00 [95% confidence interval (CI) 0.86-1.16]. No difference in stage of cancer was found (p = 0.18) nor when stratifying for calendar year. The HR for cancer-specific mortality and overall mortality after the Manchester procedure was 0.87 (95% CI 0.65-1.16) and 0.93 (95% CI 0.77-1.12), respectively. CONCLUSIONS The Manchester procedure does not affect the risk or prognosis of endometrial cancer.

Abstract
Polypropylene (PPL) mesh is widely used in pelvic floor reconstructive surgery for prolapse and stress urinary incontinence. However, some women, particularly those treated using transvaginal PPL mesh placement for prolapse, experience intractable pain and mesh exposure or extrusion. Explanted tissue from patients with complications following transvaginal implantation of mesh is typified by a dense fibrous capsule with an immune cell-rich infiltrate, suggesting that the host immune response has a role in transvaginal PPL mesh complications through the separate contributions of the host (patient), the biological niche within which the material is implanted and biomaterial properties of the mesh. This immune response might be strongly influenced by both the baseline inflammatory status of the patient, surgical technique and experience, and the unique hormonal, immune and microbial tissue niche of the vagina. Mesh porosity, surface area and stiffness also might have an effect on the immune and tissue response to transvaginal mesh placement. Thus, a regulatory pathway is needed for mesh development that recognizes the roles of host and biological factors in driving the immune response to mesh, as well as mandatory mesh registries and the longitudinal surveillance of patients.

Surgical repair of vaginal vault prolapse; a comparison between ipsilateral uterosacral ligament suspension and sacrospinous ligament fixation-a nationwide cohort study. Int Urogynecol J 2020; 32:1441-1449. [PMID: 32897459 DOI: 10.1007/s00192-020-04515-x] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2020] [Accepted: 08/21/2020] [Indexed: 02/07/2023]
Abstract
INTRODUCTION AND HYPOTHESIS Hysterectomy is frequently performed and associated with increased risk of subsequent genital prolapse including vaginal vault prolapse. Ipsilateral uterosacral ligament suspension (IUSLS) and sacrospinous ligament fixation (SSLF) are two commonly performed surgical techniques to treat vaginal vault prolapse. There is no consensus on the ideal operation technique. The aim of this study was to compare IUSLS and SSLF to treat vaginal vault prolapse based on the number of repeat surgeries. METHODS Previously hysterectomized patients operated on with IUSLS or SSLF in Denmark in 2010-2016 were included in this nationwide register-based cohort study and followed until June 2017. Data were obtained from Danish National Databases, to which reporting is mandatory by law, entailing high validity and completeness of data. Data were analyzed using Cox proportional hazard regression analysis adjusted for age, preoperative prolapse stage, smoking, BMI, and previous prolapse surgery. RESULTS In total, 744 patients were included; 384 underwent IUSLS while 360 underwent SSLF. After 5 years, 6.5% of patients operated on with IUSLS and 21.8% operated on with SSLF had a repeat surgery in the apical compartment and 12.4% and 30.6% in any compartment, respectively. The risk of repeat surgery was 4.8 times higher after SSLF compared to IUSLS [confidence interval (CI): 2.7-8.4] in the apical compartment and 2.4 times higher (CI: 1.2-5.1) in the anterior compartment. No difference was seen in the posterior compartment. CONCLUSIONS This study finds significantly higher numbers of repeat surgeries after SSLF compared to after IUSLS in a Danish nationwide cohort.

Int Urogynecol J 2020; 32:801-808. [PMID: 32780173 DOI: 10.1007/s00192-020-04482-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2020] [Accepted: 07/28/2020] [Indexed: 02/04/2023]
Abstract
INTRODUCTION AND HYPOTHESIS The aims of this study were to evaluate the impact of body mass index (BMI) on the risk of reoperation for pelvic organ prolapse (POP) up to 5 years after first-time surgery. MATERIALS AND METHODS This nationwide register-based study includes first-time POP surgery in 2010 through 2016. The cumulative incidence proportions of reoperation were analyzed in a Cox regression model and described using Kaplan-Meier plots stratified in BMI categories. RESULTS A total of 28,533 first-time procedures were performed in 22,624 women; 76.6% had single-compartment repair. The 1- and 5-year reoperation rate within the same compartment was 2.6% and 6.1% respectively for women with BMI < 25, and for women with BMI > 35 it was 3.7% and 11.2 respectively. In the anterior compartment there was a significantly increased adjusted hazard ratio for reoperation in the same compartment with increasing BMI (reference group BMI < 25), BMI 30-34.9 with an aHR = 1.34 (CI 95% 1.04-1.71) and BMI ≥ 35 aHR = 1.77 (CI 95% 1.17-2.67). The 1- and 5-year reoperation rate in an adjacent compartment was 0.6% and 1.6% respectively for women with BMI < 25, and for women with BMI > 35 it was 1.0% and 4.4 respectively. For reoperation in an adjacent compartment the adjusted results were BMI 30-34.9 aHR = 1.64 (95% CI 1.05-2.56) and BMI > 35 aHR = 2.64 (95% CI 1.36-5.14) when the first-time operation was in the anterior compartment. CONCLUSIONS If the woman had BMI > 35 and first-time surgery was in the anterior compartment, she had an almost doubled risk of reoperation within 5 years both in the same compartment and in an adjacent compartment compared to women with BMI < 35. In the apical and posterior compartment there was a trend towards increasing risk of reoperation with increasing BMI, although with a broad confidence interval.

The effect of advisory documents on mid-urethral sling case acquisition to the British Society Urogynaecology (BSUG) database in England. Int Urogynecol J 2020; 32:135-140. [PMID: 32556850 DOI: 10.1007/s00192-020-04388-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Accepted: 06/08/2020] [Indexed: 10/24/2022]
Abstract
INTRODUCTION AND HYPOTHESIS Many advisory documents have recommended uploading of all mid-urethral sling (MUS) cases onto the British Society of Urogynaecology (BSUG) or British Association of Urological Surgeons (BAUS) database. The aim of this study was to determine whether these documents have resulted in an increase in database case acquisition for MUS surgery. METHOD We determined the number of cases uploaded onto the BSUG and BAUS databases and cases acquired by Hospital Episode Statistics (HES) over the period January 2011-March 2017 for the 6 months prior to each document and 6 months afterwards. RESULTS There was an upsurge in data acquisition in 2013, which then declined after year end. There was a significant upsurge in case acquisition associated with the following documents: NHS Medical Director letter (p < 0.00001), the Healthcare Quality Improvement Partnership (HQIP) audit (p < 0.00001). There was a significant drop in case acquisition following the end of the HQIP audit (p < 0.00001) and the Mesh Working Group Interim report (p = 0.00325). CONCLUSION There was a significant increase in case acquisition with the HQIP audit and decline after it. The significant increase in case acquisition seen after the NHS MD letter in November 2012 may have been due to an overlap in the data capture between it and the HQIP audit. The levels of case acquisition do not compare to registries that are essentially compulsory and therefore we believe that voluntary databases are not effective for device post-market surveillance.

Abstract
Denmark has a large network of population-based medical databases, which routinely collect high-quality data as a by-product of health care provision. The Danish medical databases include administrative, health, and clinical quality databases. Understanding the full research potential of these data sources requires insight into the underlying health care system. This review describes key elements of the Danish health care system from planning and delivery to record generation. First, it presents the history of the health care system, its overall organization and financing. Second, it details delivery of primary, hospital, psychiatric, and elderly care. Third, the path from a health care contact to a database record is followed. Finally, an overview of the available data sources is presented. This review discusses the data quality of each type of medical database and describes the relative technical ease and cost-effectiveness of exact individual-level linkage among them. It is shown, from an epidemiological point of view, how Denmark’s population represents an open dynamic cohort with complete long-term follow-up, censored only at emigration or death. It is concluded that Denmark’s constellation of universal health care, long-standing routine registration of most health and life events, and the possibility of exact individual-level data linkage provides unlimited possibilities for epidemiological research.

Abstract
INTRODUCTION The risk of perioperative cardiovascular complications following operations for urinary incontinence and pelvic organ prolapse (POP) must be taken into consideration during surgical planning. The literature on the cardiovascular risk following urinary incontinence and POP operations shows conflicting results. Our aims were to provide an estimate of the mortality and the risk of cardiovascular complications following urinary incontinence and POP operations considering women's preoperative cardiovascular comorbidity. MATERIAL AND METHODS This nationwide register-based study includes a total of 13 992 operations for urinary incontinence and 35 765 for POP from 2007 to 2017. The risk was estimated as an incidence/rate ratio for women with and without former cardiovascular comorbidity adjusted for relevant confounders by using a case-crossover study design. RESULTS A total of 7677 patients were at high risk, with a cardiovascular comorbidity prior to the operation, and 42 076 patients were at low risk, with no cardiovascular comorbidity. Overall, 11 patients died within 30 days following an operation, of whom five were in the high-risk group and six in the low-risk group. Of the women at high risk, 0.59% had cardiovascular complications from 0 to 6 days following an operation, corresponding to an incidence/rate ratio of 3.64 (95% CI; 2.67-4.97), compared with women at low risk where no complications were registered in the first week. CONCLUSIONS We found an increased risk of cardiovascular complications following urogynecological operations in women with preoperative cardiovascular comorbidity, and no increased risk in women without prior cardiovascular comorbidity. In general, the risk of cardiovascular complications was lower than that found in previous studies.

Abstract
INTRODUCTION AND HYPOTHESIS The objective was to evaluate the impact of body mass index (BMI) on the subjective improvement and risk of reoperation after first-time mid-urethral sling surgery. METHODS Data were retrieved from the national Danish Urogynaecological Database, including women with first-time surgery with mid-urethral polypropylene slings from 2011 to 2016. The subjective improvement was assessed by the difference in symptoms based on the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) completed pre- and 3 months postoperatively. A reoperation was defined as any new surgical procedure for stress urinary incontinence performed within the study period. RESULTS During the study period, 6,414 mid-urethral sling procedures were performed; 80.0% of these women filled out both pre- and post-surgical International Consultation on Incontinence Questionnaire (ICI-Q) forms. 42.4% had a BMI < 25, 34.6% had BMI 25-30, 16.9% had BMI 30-35, and 6.0% BMI >35. The subjective improvement after surgery was high in all BMI categories and there were no differences between the categories. The overall cumulative hazard proportion at 2 years of follow-up was 1.9% (CI 95%: 1.6-2.3) and after 5 years 2.4% (CI 95%: 2.0-2.9). Adjusted for age, smoking, and use of alcohol, the cumulative hazard proportion after 2 years of follow-up was 3.2% (CI 95%: 1.6-6.2) for women with BMI >35 and after 5 years 4.0% (CI 95%: 2.0-7.7), which was the highest proportion of reoperation in the study. The crude hazard ratio was 1.84 (CI 95%: 0.89-3.83) women with BMI >35 and the adjusted hazard ratio was 1.94 (CI 95%: 0.92-4.09). CONCLUSIONS We found high subjective improvement after the first-time surgery unrelated to BMI. Women with a BMI over 35 had the highest proportion of reoperations, although this was not statistically significant.
