    Factors influencing the outcome of surgery for pelvic organ prolapse2018In: International Urogynecology Journal, ISSN 0937-3462, E-ISSN 1433-3023, Vol. 29, no 1, p. 81-89Article in journal (Refereed)
    Abstract [en]

    Pelvic organ prolapse (POP) surgery is a common gynecological procedure. Our aim was to assess the influence of obesity and other risk factors on the outcome of anterior and posterior colporrhaphy with and without mesh. Data were retrieved from the Swedish National Register for Gynecological Surgery on 18,554 women undergoing primary and repeat POP surgery without concomitant urinary incontinence (UI) surgery between 2006 and 2015. Multivariate logistic regression analyses were used to identify independent risk factors for a sensation of a vaginal bulge, de novo UI, and residual UI 1 year after surgery. The overall subjective cure rate 1 year after surgery was 80% (with mesh 86.4% vs 77.3% without mesh, p < 0.001). The complication rate was low, but was more frequent in repeat surgery that were mainly mesh related. The use of mesh was also associated with more frequent de novo UI, but patient satisfaction and cure rates were higher compared with surgery without mesh. Preoperative sensation of a vaginal bulge, severe postoperative complications, anterior colporrhaphy, prior hysterectomy, postoperative infections, local anesthesia, and body mass index (BMI) 30 were risk factors for sensation of a vaginal bulge 1 year postsurgery. Obesity had no effect on complication rates but was associated increased urinary incontinence (UI) after primary surgery. Obesity had no influence on cure or voiding status in women undergoing repeat surgery. Obesity had an impact on the sensation of a vaginal bulge and the presence of UI after primary surgery but not on complications.

    Patient-reported outcomes after sacrospinous fixation of vault prolapse with a suturing device: a retrospective national cohort study2018In: International Urogynecology Journal, ISSN 0937-3462, E-ISSN 1433-3023, Vol. 29, no 6, p. 821-829Article in journal (Refereed)
    Abstract [en]

    Introduction and hypothesis: Innovations in suturing devices have facilitated sacrospinous ligament fixation (SSF) for the correction of vaginal vault prolapse. It is uncertain if outcomes using suturing devices differ from those using a traditional suturing technique. We hypothesize that no difference exists in the efficacy and safety 1 year after SSF for vault prolapse performed with suturing devices or using a traditional technique. The objective was to compare SSF using a suturing device with traditional SSF for the treatment of vault prolapse, regarding symptoms of prolapse recurrence, patient satisfaction, incidence of re-operation, and complications 1 year postoperatively.

    Methods: We carried out a retrospective cohort study using register-based national data from 2006 to 2013. The Swedish Quality Register of Gynecological Surgery includes assessments pre-operatively, at hospital admittance, surgery, discharge, and questionnaires at 8 weeks and 1 year after surgery. Demographic variables and surgical methods were included in multivariate logistic regression analyses.

    Results: In the suturing device group (SDG, n = 353), 71.5% were asymptomatic of recurrence after 1 year compared with 78.7% in the traditional SSF group (TSG, n = 195); risk difference - 7.3% (95%CI -15.2%; 0.7%). Adjusted odds ratio (aOR) for being asymptomatic 1 year postoperatively was 0.56 (95%CI 0.31; 1.02, p = 0.057). Patient satisfaction was similar in SDG and TSG (78.1% vs 78.4%). Reoperation occurred in 7.4% in the SDG compared with 3.6% in the TSG, risk difference 3.8% (95%CI 0.0%; 7.5%), aOR 3.55 (95%CI 1.10; 11.44, p = 0.03).

    Conclusions: Patient satisfaction was similar 1 year after SSF, despite symptoms of recurrence being more likely and reoperation more common after using a suturing device compared with a traditional technique. The methods did not differ with regard to surgical complications.

    Prolapse and continence surgery in countries of the Organization for Economic Cooperation and Development in 20122015In: American Journal of Obstetrics and Gynecology, ISSN 0002-9378, E-ISSN 1097-6868, Vol. 212, no 6, article id 755.e1Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: The purpose of this study was to report the rates and types of pelvic organ prolapse (POP) and female continence surgery performed in member countries of the Organization for Economic Co-operation and Development (OECD) in 2012. STUDY DESIGN: The published health outcome data sources of the 34 OECD countries were contacted for data on POP and female continence interventions from 2010-2012. In nonresponding countries, data were sought from national or insurer databases. Extracted data were entered into an age-specific International Classification of Disease, edition 10 (ICD-10)-compliant Excel spreadsheet by 2 authors independently in English-speaking countries and a single author in non-English-speaking countries. Data were collated centrally and discrepancies were resolved by mutual agreement. RESULTS: We report on 684,250 POP and 410,352 continence procedures that were performed in 15 OECD countries in 2012. POP procedures (median rate, 1.38/1000 women; range, 0.51-2.55 prolapse procedures/1000 women) were performed 1.8 times more frequently than continence procedures (median rate, 0.75/1000 women; range, 0.46-1.65 continence procedures/1000 women). Repairs of the anterior vaginal compartment represented 54% of POP procedures; posterior repairs represented 43% of the procedures, and apical compartment repairs represented 20% of POP procedures. Median rate of graft usage was 15.7% of anterior vaginal repairs (range, 3.3-25.6%) and 8.5% (range, 3.2-17%) of posterior vaginal repairs. Apical compartment repairs were repaired vaginally at a median rate of 70% (range, 35-95%). Sacral colpopexy represented a median rate of 17% (range, 5-65%) of apical repairs; 61% of sacral colpopexies were performed minimally invasively. Between 2010 and 2012, there was a 3.7% median reduction in transvaginal grafts, a 4.0% reduction in midurethral slings, and a 25% increase in sacral colpopexies that were performed per 1000 women. Midurethral slings represented 82% of female continence surgeries. CONCLUSION: The 5-fold variation in the rate of prolapse interventions within OECD countries needs further evaluation. The significant heterogeneity (> 10 times) in the rates at which individual POP procedures are performed indicates a lack of uniformity in the delivery of care to women with POP and demands the development of uniform guidelines for the surgical management of prolapse. In contrast, the midurethral slings were the standard female continence surgery performed throughout OECD countries in 2012.

    Native-tissue repair of isolated primary rectocele compared with nonabsorbable mesh: patient-reported outcomes2017In: International Urogynecology Journal, ISSN 0937-3462, E-ISSN 1433-3023, Vol. 28, no 1, p. 49-57Article in journal (Refereed)
    Abstract [en]

    We evaluated patient-reported outcomes and complications after treatment of isolated primary rectocele in routine health-care settings using native-tissue repair or nonabsorbable mesh. We used prospective data from the Swedish National Register for Gynaecological Surgery and included 3988 women with a primary operation for rectocele between 2006 and 2014: 3908 women had native-tissue repair, 80 were operated with nonabsorbable mesh. No concurrent operations were performed. Pre- and perioperative data were collected from doctors and patients. Patient-reported outcomes were evaluated 2 and 12 months after the operation. Only validated questionnaires were used. One year after native-tissue repair, 77.8 % (76.4-79.6) felt they were cured, which was defined as never or hardly ever feeling genital protrusion; 74.0 % (72.2-75.7) were very satisfied or satisfied, and 84 % (82.8-85.9) reported improvement of symptoms. After mesh repair, 89.8 % (77.8-96.6) felt cured, 69.2 % (54.9-81.3) were very satisfied or satisfied, and 86.0 % (72.1-94.7) felt improvement. No significant differences were found between groups. Organ damage was found in 16 (0.4 %) patients in the native-tissue repair group compared with one (1.3 %) patient in the mesh group [odds ratio (OR) 3.08; 95 % confidence interval (CI) 0.07-20.30]. The rate of de novo dyspareunia after native-tissue repair was 33.1 % (30.4-35.8), comparable with that after mesh repair. The reoperation rate was 1.1 % (0.8-1.5) in both groups. Most patients were cured and satisfied after native-tissue repair of the posterior vaginal wall, and the patient-reported outcomes were comparable with results after mesh repair. The risk of serious complications and reoperation were comparable between groups.

    Vaginal prolapse surgery: an epidemiological perspective : studies of native tissue repair versus implants, surgeons´ practical experiences and five year follow-up in the swedish national quality register for gynecological surgery2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Background: Pelvic organ prolapse (POP) is a common condition that impacts on quality of life for many women. The mean age of Swedish women operated for POP is 60 years, and with a life expectancy of approximately 84 years this means that the average patient will live 24 years subsequent to the operation. Therefore, sustainable long-term results of POP surgery are essential. In an effort to improve long-term outcomes of vaginal prolapse surgery, mesh materials have been developed for this purpose. In Sweden, synthetic mesh is used in 7.4% of all primary operations without any coherent consensus about their use. Prolapse surgery is regarded as a routine procedure performed at almost every hospital in Sweden, but a large proportion of the surgeons are inexperienced. In actuality, 73% of them perform the procedure once a month or less frequently. Simultaneously, surgery for POP has been reported to have a highfailure rate internationally. For most surgeons, the operation is a low-frequency procedure, and outcomes have been reported as unsatisfactory. The specific aims of these thesis were to examine:- Mesh-augmented repairs impact on operative results compared to nativetissue repair.- Surgical experience in performing a specific operation and utilize this knowledge in analysing how it may (or may not) affect operative results.- Long-term (5 year) national follow up of POP operations, regarding both the objective epidemiological data and the patient-reported outcomes.

    Methods: The studies in this thesis are based on data from the Swedish National Quality Register for Gynaecological Surgery (GynOp), which covers approximately 90% of all gynaecological operations in Sweden. The comparative follow-up of POP surgery using non-absorbable polypropylene mesh versus colporrhaphy using native tissue was analysed in two different cohorts, of women with a primary cystocele and women with a relapse after surgery for a rectocele. Both surgeon reported results and patient-reported outcomes (PROMs) were analysed 1 year post-surgery. Information about surgeons’ experience in performing POP operations was extracted from GynOp over 9 years. Inclusion criteria were otherwise healthy patients who underwent anterior or posterior native tissue repair, or both. The operations were divided into four groups according to the operative experience of the surgeon (measured as average number of operations per active year). Both PROM results and surgeon-reported outcomes after 1 year were investigated. For the long-term follow-up 5 years after any operation for a vaginal prolapse, a new questionnaire to capture PROM data was designed, validated and nationally distributed. Information about re-operations was extracted directly from GynOp.

    Results: Mesh-augmented repair of a primary cystocele had a significantly better outcome in terms of absence of symptoms, compared with native tissue repair, OR 1.53(95% CI 1.10-2.13), but also had more complications directly related to the procedure (OR 1.51, RD=6.6%). For recurrent rectocele, mesh was superior to native tissue repair, OR 2.06 (95% CI 1.03-4.35); the number of postoperative complications was equal in the two groups. Among the 1,092 surgeons who were active POP surgeons during the study, 803(73%) participated in POP operations once a month or less frequently in their active years. No differences in patient or surgeon-reported outcomes were seen between the “experience groups”. Kaplan-Meier curves for re-operation after a primary POP operation showed an overall retreatment rate of 11.2% after 5 years. The response rate for the patient questionnaire was 74.9%. Overall, 70% of the patients reported no symptoms, and around 72% and 82% were satisfied with the operative results and felt that their symptoms had improved, respectively.

    Discussion: Mesh use was, after 1 year of follow-up, generally characterized by a high cure rate and varying degrees of complications, such as postoperative pain. However, for recurrent rectocele, we found no immediate drawbacks of the method compared with native tissue repair, with the same high cure rate as seen in other compartments. Surgeon experience had no impact on the native tissue operation, and any inconsistency of outcome is more likely inherent in the method than attributable to a surgeon’s lack of experience.The 5-year results indicate that native tissue repair produces much better results, judging from overall Swedish results, than previously thought. This is backed up both by objective data indicating a minimal number of re-operations within 5 years for the most common cases (i.e. primary rectocele and cystocele) and by the outcomes reported by the patients themselves.

    Conclusions: Mesh-augmented repair is more effective than native tissue repair forrecurrent rectocele, and without increased risk of complications. Drawbacks of mesh repair vary for other compartments, and for primary operations.- Surgeons’ operative experience in routine POP operations using native tissue has no impact on outcome after 1 year.- Long-term results of POP repair with native tissue are excellent, with a low risk of re-operation and a persistent absence of subjective symptoms.

    Impact of surgeon experience on routine prolapse operations2018In: International Urogynecology Journal, ISSN 0937-3462, E-ISSN 1433-3023, Vol. 29, no 2, p. 297-306Article in journal (Refereed)
    Abstract [en]

    Introduction and hypothesis: Surgical work encompasses important aspects of personal and manual skills. In major surgery, there is a positive correlation between surgical experience and results. For pelvic organ prolapse (POP), this relationship has to our knowledge never been examined. In any clinical practice, there is always a certain proportion of inexperienced surgeons. In Sweden, most prolapse surgeons have little experience in performing prolapse operations, 74% conducting the procedure once a month or less. Simultaneously, surgery for POP globally has failure rates of 25-30%. In other words, for most surgeons, the operation is a low-frequency procedure, and outcomes are unsatisfactory. The aim of this study was to clarify the acceptability of having a high proportion of low-volume surgeons in the management of POP.

    Methods: A group of 14,676 exclusively primary anterior or posterior repair patients was assessed. Data were analyzed by logistic regression and as a group analysis.

    Results: Experienced surgeons had shorter operation times and hospital stays. Surgical experience did not affect surgical or patient-reported complication rates, organ damage, reoperation, rehospitalization, or patient satisfaction, nor did it improve patient-reported failure rates 1 year after surgery. Assistant experience, similarly, had no effect on the outcome of the operation.

    Conclusions: A management model for isolated anterior or posterior POP surgery that includes a high proportion of low-volume surgeons does not have a negative impact on the quality or outcome of anterior or posterior colporrhaphy. Consequently, the high recurrence rate was not due to insufficient experience of the surgeons performing the operation.

    Repair of recurrent rectocele with posterior colporrhaphy or non-absorbable polypropylene mesh: patient-reported outcomes at 1-year follow-up.2019In: International Urogynecology Journal, ISSN 0937-3462, E-ISSN 1433-3023, Vol. 30, no 10, p. 1679-1687Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION AND HYPOTHESIS: The aim of this study was to compare the results of repair of isolated, recurrent, posterior vaginal wall prolapse using standard posterior colporrhaphy versus non-absorbable polypropylene mesh in a routine health care setting.

    METHODS: This cohort study was based on prospectively collected data from the Swedish National Register for Gynaecological Surgery. All patients operated for recurrent, posterior vaginal wall prolapse in Sweden between 1 January 2006 and 30 October 2016 were included. A total of 433 women underwent posterior colporrhaphy, and 193 were operated using non-absorbable mesh. Data up to 1 year were collected.

    RESULTS: The 1-year patient-reported cure rate was higher for the mesh group compared with the colporrhaphy group, with an odds ratio (OR) of 2.06 [95% confidence interval (CI) 1.03-4.35], corresponding to a number needed to treat of 9.7. Patient satisfaction (OR = 2.38; CI 1.2-4.97) and improvement (OR = 2.13; CI 1.02-3.82) were higher in the mesh group. However, minor surgeon-reported complications were more frequent with mesh (OR = 2.74; CI 1.51-5.01). Patient-reported complications and re-operations within 12 months were comparable in the two groups.

    CONCLUSIONS: For patients with isolated rectocele relapse, mesh reinforcement enhances the likelihood of success compared with colporrhaphy at 1-year follow-up. Also, in our study, mesh repair was associated with greater patient satisfaction and improvement of symptoms, but an increase in minor complications. Our study indicates that the benefits of mesh reinforcement may outweigh the risks of this procedure for women with isolated recurrent posterior prolapse.

    Decisions to use surgical mesh in operations for pelvic organ prolapse: a question of geography?2019In: International Urogynecology Journal, ISSN 0937-3462, E-ISSN 1433-3023, Vol. 30, no 9, p. 1533-1539Article in journal (Refereed)
    Abstract [en]

    Introduction and hypothesis: Surgical mesh can reinforce damaged biological structures in operations for genital organ prolapse. When a method is new, scientific information is often contradictory. Individual surgeons may accept different observations as useful, resulting in conflicting treatment strategies. Additional scientific information should lead to increasing convergence.

    Methods: Based on data from the Swedish National Quality Register of Gynecological Surgery, all patients who underwent their first recurrent anterior compartment prolapse operation between 2006 and 2017 were included (2758 patients). Surgical mesh was used in 56.5%. We analyzed inter-county disparities in and patterns of mesh use over 12 years. To minimize confounding, we selected a group of highly comparable patients where similar decision patterns could be expected.

    Results: The use of mesh differed between counties by a factor of 11 (8.6-95.3%). Counties with low use of mesh continued with low use and counties with high use continued with high use.

    Conclusions: Decisions regarding how to interpret existing scientific information about mesh implants in the early years of mesh use have led to "communities of practice" highly influenced by geographical factors. For 12 years, these groups have made disparate decisions and upheld them without measurable change toward consensus. The scientific learning process has stopped-despite the abundance of new publications and the steady supply of new types of mesh. Ongoing disparity in surgeons' choices in comparable patients has an adverse effect on clinical care. For the patient, this represents 12 years of a geographical lottery concerning whether mesh is used or not.
