Rates of Sling Procedures and Revisions-A National Surgical Quality Improvement Program Database Study

Comparison of perioperative adverse events following suburethral sling placement using synthetic mesh, autologous rectus fascia, and autologous fascia lata in a national surgical registry

AIMS

To assess and compare 30-day perioperative adverse events following suburethral sling surgery using synthetic mesh, autologous rectus fascia, and autologous fascia lata in women.

METHODS

This was a retrospective cohort study of patients who underwent fascial or synthetic sling placement for stress urinary incontinence between 2008 and 2021 using the American College of Surgeons' National Surgical Quality Improvement Program database. Current Procedural Terminology codes were used to identify patients undergoing each type of sling procedure. Multivariable regression analysis with stepwise regression was used to assess the odds of composite adverse events (e.g., urinary tract infection, surgical site infection, pulmonary embolism, and other reportable events) between cohorts.

RESULTS

Of the 41 533 female patients who underwent isolated suburethral sling placement without concurrent procedures, 41 292 (99.4%) received a synthetic mesh sling, and 241 (0.6%) received an autologous facial sling. In the fascial sling cohort, 160 (66.4%) underwent rectus fascia harvest and 81 (33.6%) underwent fascia lata harvest. Sling surgeries involving autologous fascia were associated with increased odds of adverse events compared to those involving synthetic mesh, even after adjusting for confounders (adjusted odds ratio [aOR]: 3.63, 95% confidence interval [CI]: 2.56-5.15). Compared to fascial slings from rectus fascia, slings from fascia lata were associated with increased odds of composite adverse events (aOR: 2.11, 95% CI: 1.03-4.04). However, with the exclusion of urinary tract infections, the adverse event rate was similar between slings using the two fascial harvest techniques (aOR: 1.93, 95% CI: 0.81-4.63).

CONCLUSIONS

In this retrospective database study, suburethral sling surgeries using autologous fascia were independently associated with a 3.6-fold increase in odds of 30-day perioperative adverse events compared to sling surgeries using synthetic mesh.

Complications of Synthetic Midurethral Slings: Is There a Relevant Discrepancy Between Observational Data and Clinical Trials?

CONTEXT

The complications of synthetic midurethral slings (MUSs) in women with stress urinary incontinence (SUI) have become a globally debated issue.

OBJECTIVE

To systematically review the short- and long-term complications of mesh slings reported in observational data compared with clinical trial data, to determine whether the complication rates from clinical trials reflects "real-world" observational data.

EVIDENCE ACQUISITION

PubMed and Cochrane Library were searched. Methods as detailed in Preferred Reporting Items for Systematic Reviews and Meta-analyses and Cochrane Handbook for Systematic Reviews of Interventions were followed.

EVIDENCE SYNTHESIS

Thirty registries/databases including 709 335 MUS procedures (1-22 yr of follow-up) were identified. MUS procedures were associated with intraoperative bladder perforation in 0.86-3.6%, urethral perforation in 0-0.1%, vascular injury in 0.04-0.1%, voiding lower urinary tract symptoms (LUTS) in 1.47-3.5%, vaginal exposure in 0.2-1.9%, and reoperation in up to 9% of cases. Forty-three randomised clinical trials were identified, including 6284 women who underwent MUS procedures and 2177 women who underwent other interventions (1-10 yr of follow-up). MUS procedures were associated with urinary tract perforation in 2.58%, vaginal injury in 1.43%, de novo voiding LUTS in 4.37%, de novo storage LUTS in 5.41%, mesh extrusion/exposure (vaginal/urinary tract) in 2.54%, dyspareunia in 2.26%, pain (pelvic/suprapubic/perineal) in 2.83%, and reoperation for complications required in 1.82% of cases. Meta-analyses of the randomised controlled trials revealed that retropubic MUSs were associated with more events of urinary tract perforation (risk ratio [RR] 9.81, 95% confidence interval [CI] 5.05-19.04, high certainty of evidence [COE]) and voiding LUTS (RR 1.57, 95% CI 1.19-2.07, high COE) than transobturator MUSs. MUSs were associated with more events of pain than mini-slings (RR 1.72, 95% CI 1.04-2.87, moderate COE).

CONCLUSIONS

Short- and long-term data on complications of polypropylene mesh used for female SUI are fairly comparable when using outcome data from well-designed clinical trials or from less structured prospective or retrospective registries. Comparisons have to be made with caution since the two systems of data collection are inherently incomparable. This knowledge should be incorporated in the discussion on how to implement polypropylene mesh for female stress incontinence.

PATIENT SUMMARY

In order to know whether mesh tapes used for treating stress incontinence work well and are safe, high-quality information is important. It appears that well-designed clinical studies give similar results to large registration databases. These data should be interpreted with caution in view of the different ways the information was collected. These results will help physicians and patients understand the risks of mesh tapes.

Changing Practices in the Surgical Management of Adnexal Torsion: An Analysis of the National Surgical Quality Improvement Program Database

OBJECTIVE

To evaluate trends in the surgical management of adnexal torsion and to evaluate these trends with respect to the updated American College of Obstetricians and Gynecologists (ACOG) guidelines.

METHODS

We performed a retrospective cohort study using the National Surgical Quality Improvement Program database. Women who underwent surgery for adnexal torsion between 2008 and 2020 were identified on the basis of International Classification of Diseases codes. Surgeries were grouped as either ovarian conservation or oophorectomy with the use of Current Procedural Terminology codes. Patients were also grouped into year cohorts with respect to the publication of the updated ACOG guidelines (2008-2016 compared with 2017-2020). Multivariable logistic regression, weighted by cases per year, was used to assess differences between groups.

RESULTS

Of the 1,791 surgeries performed for adnexal torsion, 542 (30.3%) involved ovarian conservation and 1,249 (69.7%) involved oophorectomy. Older age, higher body mass index, higher American Society of Anesthesiologists classification, anemia, and diagnosis of hypertension were significantly associated with oophorectomy. There was no significant difference in the proportion of oophorectomies performed before 2017 compared with after 2017 (71.9% vs 69.1%, odds ratio [OR] 0.89, 95% CI 0.69-1.16; adjusted OR 0.94, 95% CI 0.71-1.25). A significant decrease in proportion of oophorectomies performed each year was identified over the entire study period (-1.6%/y, P=.02, 95% CI -3.0% to -0.22%); however, the rates did not differ before and after 2017 (interaction P=.16).

CONCLUSION

There was a modest decrease in the proportion of oophorectomies for adnexal torsion performed per year over the study period. However, oophorectomy is still commonly performed for adnexal torsion, despite updated guidelines from ACOG recommending ovarian conservation.

Trends in Performance of Anti-Incontinence Treatment at the Time of Pelvic Organ Prolapse Repair From 2011 to 2019

IMPORTANCE

There are no publications on national trends in performance of concomitant stress urinary incontinence (SUI) treatment with pelvic organ prolapse surgery over the past decade.

OBJECTIVES

The objective of this study was to describe trends in the performance and type of concomitant SUI treatment from 2011 to 2019.

STUDY DESIGN

Surgical procedures for pelvic organ prolapse and coding for prolapse repair were identified from the American College of Surgeons National Surgical Quality Improvement Program database. An autoregressive interrupted time series model estimated temporal trends in concomitant SUI treatment associated with 3 consequential events: U.S. Food and Drug Administration's (FDA) requirement for postmarketing studies from mesh manufacturers (January 2012), publication of the Outcomes following Vaginal Prolapse Repair and Midurethral Sling (OPUS) trial (June 2012), and the FDA's reclassification of vaginal mesh as a high-risk device (January 2016).

RESULTS

There were 43,370 cases identified. The rate of concomitant SUI treatment decreased from 46.1% to 35.7% across the analysis period. No significant trend before postmarketing studies (-0.2%; 95% confidence interval [CI], -0.8 to 1.1) was observed. After postmarketing studies, there was a downward deflection of -2.0% per quarter (95% CI, -3.6 to -0.4). After OPUS, we observed a flattening of the trend to -0.2% (95% CI, -0.8 to 0.4) that persisted after FDA reclassification. Sling procedures remained predominant (96.2% of SUI procedures) and performance of urethropexy decreased across the analysis period (-0.1%; 95% CI, -0.08 to -0.2).

CONCLUSIONS

After the FDA's order for postmarketing studies, rates of concomitant SUI treatment significantly decreased. Rates stabilized after the OPUS trial at around 35% and did not subsequently change. Rates of nonmesh concomitant SUI treatment decreased during the analysis period.
