“… 17–20 Our previous study reported long-term efficacy prediction of LSG for morbid obesity in the Chinese population. 21 , 22 However, it did not verify the predictive effect of the model regarding weight loss success/failure or establish a linear prediction model for long-term %EWL. Chinese guidelines recommend LSG for patients with BMI ≥ 32.5 kg/m 2 .…”

Purpose To evaluate the predictive effect of the initial weight loss on the long-term weight loss in Chinese patients with a body mass index (BMI) ≥ 32.5 kg/m 2 who underwent LSG. Patients and Methods The follow-up was completed via phone or WeChat for outpatients and at the hospital for inpatients. We evaluated the BMI, percentage of excess weight loss (%EWL), and type 2 diabetes mellitus, hypertension, and hyperlipidemia statuses. Linear and logistic regression analyses were performed on the relationship between the initial and long-term weight loss. The optimal cut-off value was determined by receiver operating characteristic (ROC) curve analysis. Results We enrolled 307 patients, with a median preoperative BMI of 39.68 (35.68, 45.47) kg/m 2 . %EWL ≥ 50% was regarded as successful weight loss, and 76.55% of the patients lost their weight successfully. (Reviewer #1, comment #4) %EWL at 6 months and 5 years were positively correlated ( P < 0.001). Further, the following linear equation could express the relationship: (%EWL 5 years = 29.193 + 0.526 × %EWL 6 months ). %EWL ≥ 58.57% at 6 months was the best predictor of successful weight loss at 5 years after LSG (Reviewer #1, comment #5) (sensitivity, 73.62%; specificity, 73.61%; AUC value, 0.780). Internal verification of the prediction model revealed satisfactory results in terms of discrimination and calibration. Conclusion In Chinese patients with BMI ≥ 32.5 kg/m 2 who underwent LSG, %EWL at 6 months and 5 years were correlated. %EWL ≥ 58.57% at 6 months was a predictor of successful long-term weight loss.

“…The proposed nomogram resulted in more accurate nonremission prediction for patients with obesity after metabolic surgery and may provide a reference for the preoperative choice of surgical procedures ( Mao et al, 2021 ). With successful weight loss defined as %EWL >50%, a %EWL value of 56.54% at 6 months was the best predictor of successful weight loss at 5 years (sensitivity = 72.38%, specificity = 82.69%) in Chinese patients with morbidly obesity ( Wang et al, 2021 ).…”

Obesity and its related complications comprise a serious public health problem worldwide, and obesity is increasing in China. Metabolic surgery is a new type of treatment with unique advantages in weight loss and obesity-related metabolic complications. The pathogenesis of obesity is complex and not yet fully understood. Here, we review the current efficacy and safety of metabolic surgery, as well as recent progress in mechanistic studies and surgical procedures in China. The exciting and rapid advances in this field provide new opportunities for patients with obesity and strike a balance between long-term effectiveness and safety.
