Mammary Volume-to-Body Mass Index Ratio: Preoperative Predictor of Cardiovascular Risk Factor and Indicator of Long-term Postoperative Remission of Comorbidities in Premenopausal Women Undergoing Sleeve Gastrectomy.

Purpose: A correct preoperative selection of candidates to undergo a sleeve gastrectomy (SG) is advisable. However, there is a dearth of available literature addressing outcome predictors after SG, besides surgical factors. To assess the accuracy of the mammary volume-to-body mass index (MV-BMI) ratio as an indicator of cardiovascular disease (CVD) risk in morbidly obese patients and as a preoperative predictor of long-term outcomes after SG.

Materials And Methods: A prospective observational study of 100 consecutive females under 40 years old and planned to undergo a SG was performed. Mammary volume was calculated based on a geometry of the breast model. Correlation of the preoperative MV-BMI ratio with preoperative Framingham risk score (FRS) and triglyceride/HDL-cholesterol ratio was investigated. The correlation of preoperative MV-BMI with 5-year postoperative remission of comorbidities was also assessed.

Results: Preoperative MV-BMI showed an inverse correlation with preoperative FRS and triglyceride/high-density lipoprotein-cholesterol ratio. It also showed a direct correlation with long-term T2D, hypertension, and dyslipidemia remission after SG. A cutoff point of MV-BMI 60 has been established as the most accurate predictive value.

Conclusion: MV-BMI can be used as a predictive factor of long-term outcome after SG in premenopausal women.
