Abstract
PURPOSE: To evaluate whether preoperative visceral fat-related indexes, such as visceral adiposity index (VAI), lipid accumulation product (LAP), Chinese visceral adiposity index (CVAI), and metabolic score for visceral fat (METS-VF), are useful for predicting diabetes remission in Chinese patients with a BMI < 35 kg/m2 after bariatric surgery. MATERIALS AND METHODS: A retrospective, multicenter cohort study enrolled 177 patients. Binary logistic regression and receiver operating characteristic (ROC) curves were used to identify predictors and clinically useful cutoff values, respectively. The correlation between the visceral fat-related index and body fat percentage was assessed. RESULTS: Complete remission of type 2 diabetes (T2DM) was observed in 66 patients (37.29%) 1 year after surgery. The VAI, LAP, CVAI, and METS-VF showed downward trends postsurgery. Patients with complete remission had a significantly shorter duration of diabetes and higher CVAI, VAI, LAP, and BMI values than those without complete remission. Binary logistic regression and ROC analysis confirmed that diabetes duration and LAP can predict diabetes remission after bariatric surgery, and a LAP of 67.725 is a useful threshold for predicting surgical efficacy. LAP was significantly positively correlated with VAT/total (%) (p < 0.05). CONCLUSION: Preoperative LAP is a feasible tool for predicting T2DM remission in patients with a BMI < 35 kg/m2 after bariatric surgery, and a LAP of 67.725 is a useful threshold for predicting surgical outcomes. LAP was significantly positively correlated with VAT content.
