Effect of Bariatric Surgery on Urinary Incontinence in Obese Women: A Meta-analysis and Systematic Review

Perceived Benefits of Bariatric Surgery: Patient Perspectives

BACKGROUND

Obesity is a chronic and complex disease characterized by the excessive accumulation of adipose tissue, which has detrimental effects on health. Evaluating the changes in quality of life (QoL) after bariatric surgery complements the medical benefits which are documented by healthcare professionals.

PURPOSE

To study the perceived health benefits 1 year after substantial weight loss induced by bariatric surgery.

METHODS

This pilot study evaluated patients 1 year after bariatric surgery using 13 questions related to the health domains of the KOSS: airway, body mass, cardiovascular risk, diabetes, economic impact, functional, gonadal impact, health status perceived, image, junction of the gastro-esophagus, kidney, liver, and medication. In addition, the patients were asked to score the most significant benefit as "1," while the least beneficial benefit was scored as "13."

RESULTS

One hundred fourteen consecutive patients were evaluated (men = 37 and women = 77). The responses were divided into functional, metabolic, and mental/social benefits. Patients ranked the functional question, "I became more active, and I can do more things" as the most important (average score of 3.7 ± 0.2), followed by a question related to metabolic status: "I am less worried about my risk of heart disease" (4.5 ± 0.3), and then a social/mental question, "My clothes fit better" (5.4 ± 0.3). The three least valuable benefits for the cohort were sexual life improvements (8.9 ± 0.3), heartburn improvements (9.0 ± 0.3), and urinary incontinence improvements (9.8 ± 0.3).

CONCLUSIONS

Our observational pilot study demonstrated that patients value functional benefits after substantial weight loss the most, but that metabolic benefits and social/mental health benefits are also considered important.

Review: Sex-Specific Aspects in the Bariatric Treatment of Severely Obese Women

This systematic literature review aims to point out sex-specific special features that are important in the bariatric treatment of women suffering from severe obesity. A systematic literature search was carried out according to Cochrane and Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P) guidelines. After the literature selection, the following categories were determined: sexuality and sexual function; contraception; fertility; sex hormones and polycystic ovary syndrome; menopause and osteoporosis; pregnancy and breastfeeding; pelvic floor disorders and urinary incontinence; female-specific cancer; and metabolism, outcome, and quality of life. For each category, the current status of research is illuminated and implications for bariatric treatment are determined. A summary that includes key messages is given for each subsection. An overall result of this paper is an understanding that sex-specific risks that follow or result from bariatric surgery should be considered more in aftercare. In order to increase the evidence, further research focusing on sex-specific differences in the outcome of bariatric surgery and promising treatment approaches to female-specific diseases is needed. Nevertheless, bariatric surgery shows good potential in the treatment of sex-specific aspects for severely obese women that goes far beyond mere weight loss and reduction of metabolic risks.

The Impact of Bariatric Surgery on Pelvic Floor Dysfunction: A Systematic Review

OBJECTIVE

To determine the effect of bariatric surgery (BS) on the prevalence of pelvic floor dysfunctions (PFD), specifically on urinary incontinence (UI), pelvic organ prolapse (POP), and fecal incontinence (FI).

DATA SOURCES

A systematic review (PROSPERO registration no. CRD42017068452) with a literature search was performed using the PubMed, Scopus, and SciELO databases for all publications related to BS and PFD, with no language restrictions, from inception to September 2018.

METHODS OF STUDY SELECTION

Two authors screened for study eligibility and extracted data. Only prospective cohorts assessing women with morbid obesity and the prevalence of PFD before and after BS in multiple academic and private centers were included. UI, POP, and FI were defined according to the International Urogynecological Association/International Continence Society joint consensus, and diagnosis was made based on self-report or questionnaires.

TABULATION, INTEGRATION, AND RESULTS

Our search strategy retrieved 957 results. Of those, 28 studies were included for full analysis, and 20 studies (n = 3684 patients) were selected for final analysis. The main reasons for exclusion were missing data before and after BS (n = 7) and combined data of men and women who underwent BS (n = 1). Laparoscopic Roux-en-Y gastric bypass was the most common surgical technique. Pooled analysis (16 studies) showed that women had a mean body mass index reduction of 12.90 kg/m2 after treatment (95% confidence interval [CI], -14.82 to -10.97; p < .0001). The relative risk reduction was 67% (n = 19; odds ratio [OR], 0.33; 95% CI, 0.26-0.41; p < .0001) for UI, 52% (n = 5; OR, 0.48; 95% CI, 0.22-1.07; p = .07) for POP, and 20% (n = 9; OR, 0.80; 95% CI, 0.53-1.21; p = .29) for FI. Funnel plots for UI and FI did not suggest any publication bias. With regard to the standardized questionnaires for PFD, the International Consultation on Incontinence-Short Form, Pelvic Floor Impact Questionnaire-7 and its subscale Colorectal-Anal Impact Questionnaire-7, Pelvic Floor Distress Inventory-20, and its subscale Urinary Distress Inventory-6 showed statistically significantly lower scores. Sexual function, represented by the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire-12, showed no statistically significant improvement after surgery.

CONCLUSION

BS has a significant impact on reducing UI, but FI and POP, in obese women.
