Abstract
Laparoscopic Roux-en-Y gastric bypass (LRYGB) is classic bariatric procedure with long-term safety and efficacy. However, no studies have focused on predicting long-term weight loss after LRYGB in Chinese patients with body mass index (BMI) ≥ 32.5 kg/m2. To explore the relationship between initial and long-term weight loss after LRYGB in patients with BMI ≥ 32.5 kg/m2. All patients were followed-up to evaluate BMI, percentage of excess weight loss (%EWL), and comorbidities. Linear and logistic regression were performed to assess the relationship between initial and long-term weight loss. Receiver operating characteristic curve was used to determine optimal cutoff value. We enrolled 104 patients. The median preoperative BMI was 41.44 (37.92-47.53) kg/m2. %EWL ≥ 50% at 5 years was considered as successful weight loss, and 75.00% of the patients successfully lost weight. The cure rates of hypertension, hyperlipidemia, and type 2 diabetes mellitus at 1 year were 84.38%, 33.93%, and 60.82%, respectively. %EWL at 6 months and 5 years were positively correlated and its relationship could be described by following linear equation: %EWL5 years = 43.934 + 0.356 × %EWL6 months (P < .001; r2 = 0.166). The best cutoff %EWL at 6 months after LRYGB to predict 5-year successful weight loss was 63.93% (sensitivity, 53.85%; specificity, 84.62%; area under the curve (AUC) = 0.671). In Chinese patients with BMI ≥ 32.5 kg/m2, %EWL at 6 months and 5 years were positively correlated and %EWL at 5 years could be calculated by following linear equation: %EWL5 years = 43.934 + 0.356 × %EWL6 months.

An Assessment of the Effect of Bariatric Surgery on Cardiovascular Disease Risk in the Chinese Population Using Multiple Cardiovascular Risk Models. Diabetes Metab Syndr Obes 2023; 16:1029-1042. [PMID: 37077577 PMCID: PMC10106329 DOI: 10.2147/dmso.s389346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Accepted: 03/31/2023] [Indexed: 04/20/2023] Open
Abstract
BACKGROUND Many studies have reported that bariatric surgery may reduce postoperative cardiovascular risk in patient with obesity, but few have addressed this risk in the Chinese population. OBJECTIVE To assess the impact of bariatric surgery on cardiovascular disease (CVD) risk in the Chinese population using the World Health Organization (WHO) risk model, the Global risk model, and the Framingham Risk Score. METHODS We retrospectively analyzed data collected on patient with obesity who underwent bariatric surgery at our institution between March 2009 and January 2021. Their demographic characteristics, anthropometric variables, and glucolipid metabolic parameters were assessed preoperatively and at their 1-year postoperative follow-up. Subgroup analysis compared body mass index (BMI) < 35 kg/m2 and BMI ≥ 35 kg/m2, as well as gender. We used the 3 models to calculate their CVD risk. RESULTS We evaluated 61 patients, of whom 26 (42.62%) had undergone sleeve gastrectomy (SG) surgery and 35 (57.38%) Roux-en-Y gastric bypass (RYGB) surgery. Of the patients with BMI ≥ 35 kg/m2, 66.67% underwent SG, while 72.97% with BMI < 35 kg/m2 underwent RYGB. HDL levels were significantly higher at 12 months postoperatively relative to baseline. When the models were applied to calculate CVD risk in Chinese patients with obesity, the 1-year CVD risk after surgery were reduced lot compared with the preoperative period. CONCLUSION Patient with obesity had significantly lower CVD risks after bariatric surgery. This study also demonstrates that the models are reliable clinical tools for assessing the impact of bariatric surgery on CVD risk in the Chinese population.

[PMID: 35201570 PMCID: PMC8867692 DOI: 10.1007/s11695-022-05958-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Revised: 01/24/2022] [Accepted: 02/02/2022] [Indexed: 11/02/2022]
Abstract
PURPOSE Patients with mild obesity especially in absence of associated medical problems (OAMP) are commonly managed by non-surgical approaches. Laparoscopic sleeve gastrectomy (LSG) has proved itself to be effective and it is now the most performed weight loss procedure. We aimed to study the effectiveness and safety of LSG for weight loss in mild obesity. METHODS A prospective cohort study. Group A; BMI (30-34.9 kg/m2), and group B; BMI ≥ 40 or BMI ≥ 35 with OAMP. Demographic data, perioperative complications, % excess weight loss (EWL), % total weight loss (TWL), nutritional profile, and evolution of OAMP were recorded and statistically analyzed. RESULTS A total of 250 patients, with 80 patients (32%) in group A, and 170 (68%) in group B. The majority were female. The mean preoperative weight, BMI, and excess weight were 90.1 ± 9.52, 32.7 ± 1.4, and 21.5 ± 4.9 in group A, and 129.88 ± 26.12, 47.8 ± 8.2, and 62.3 ± 23.6 kg in group B respectively. The low BMI group had significantly lower OAMP, with higher pre-LSG non-surgical procedures rate. Overall post-operative morbidity rate was significantly higher in group B. %TWL was significantly lower in low BMI group. Nutritional profile was within the normal range in both groups at 3-year follow-up. CONCLUSION Laparoscopic sleeve gastrectomy is a safe and effective weight loss solution for mild obesity with better outcome than for higher BMI. Further studies are warranted to reconsider NIH's statement for medicolegal aspects, and for matching the current changes in bariatric surgery practice, safety evidence, and patients' demand.

Abstract
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/m2 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/m2. %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: (%EWL5 years = 29.193 + 0.526 × %EWL6 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/m2 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.

Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) is considered the gold standard procedure for bariatric surgery that leads to sustained weight loss and amelioration of obesity-related comorbidities. OBJECTIVES To verify long-term efficacy and safety and to investigate the influence of early weight loss on post-RYGB long-term weight maintenance in obese Chinese with body mass index (BMI) < 35 kg/m2. METHODS All patients were followed up for evaluating the variations in their BMI, percentage of excess weight loss (%EWL), and total body percentage weight loss (%TWL). Linear regression models were applied to evaluate the effects of early weight loss on successful weight maintenance. Optimal cutoff values were analyzed via plotting the receiver operative characteristic (ROC) curve. RESULTS In the current study, 143 patients were recruited. Preoperative BMI and weight were recorded as 32.24 (29.39-33.12) kg/m2, and 88.90 ± 9.52 kg, respectively. At 1, 3, and 5 years, successful weight loss i.e., greater than 25% TWL was attained by 46.85%, 37.76%, and 37.06% of patients, respectively. The obtained data revealed that %TWL at 0.5 years was considerably associated with %TWL for up to 5 years (P-value <0.001). Based on the ROC curve, %TWL of 24.39% at 0.5 years best predicted effective weight loss at 5 years (sensitivity 71.70%, specificity 82.22%). CONCLUSION RYGB is a safe and effective approach for weight loss and %TWL at 6 months might be used for predicting weight maintenance up to 5 years post-RYGB in obese Chinese with a BMI <35 kg/m2.

Abstract
BACKGROUND As a modification of the duodenal switch (DS), single-anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) has recently become very popular and is successful for weight loss and T2DM remission. However, current studies have been mostly aimed at patients with severe obesity. OBJECTIVES In this study, we firstly compare primary SADI-S to the Roux-en-Y gastric bypass (RYGB) in Chinese with diabetes and BMI< 35 kg/m2. METHODS Using a propensity score (PS) matching analysis, we analyzed all patients with diabetes and BMI< 35 kg/m2 who underwent primary SADI-S or RYGB. All surgeries were conducted by a single surgeon at a Chinese center from June 2017 to January 2019. RESULTS Twenty-six patients who underwent SADI-S and 65 patients who underwent RYGB were included in our analysis. Of these, 26 (100%) of patients in the SADI-S group and 43 (66%) of patients in the RYGB group completed the 24-month follow-up. No severe perioperative complication was observed in either group. There was a statistically higher percentage of total weight loss with SADI-S at the 2-year follow-up when compared to RYGB (p = 0.017 after PS correction). After PS adjustment, 76.5% of patients in the SADI-S group and 82.4% of patients in the RYGB group achieved complete remission of T2DM (p = 1.000). Nutritional outcomes were similar in the two groups. CONCLUSION In Chinese with diabetes and BMI< 35 kg/m2, with comparable T2DM remission and nutritional outcomes, primary SADI-S allows for better weight loss than RYGB. Compared with RYGB, SADI-S is also a safe, effective, and feasible treatment for these patients.

Abstract
To evaluate whether the learning curve for sleeve gastrectomy could be completed after 50 cases. First 100 patients undergoing LSG under a newly trained laparoscopic surgeon were included in this study and divided into two groups of 50 consecutive patients each. Perioperative outcomes were compared to recently introduced global benchmarks. Short-term weight loss was calculated as Total Weight Loss Percent (%TWL) and complications were classified in accordance with the Clavien–Dindo classification. CUSUM analysis was performed for operative time and hospital stay. Mean preoperative age and BMI were 41.8 ± 10.3 years and 42.9 ± 5.4 kg/m2, respectively. Demographics and rate of patients with previous surgery were comparable preoperatively in the two groups. Mean operative time was 92.1 ± 19.3 min and hospital stay was 3.4 ± 0.6 days as per our standard protocol of discharge. Uneventful postoperative course was recorded in 93% of patients and only one case of staple line leak was registered in the first 50 cases (group 1). No statistical difference in BMI and %TWL was found between the two groups at any time of follow-up. Comparison between two groups showed a significant reduction in hospital stay and operative time after the first 50 LSGs (p < 0.05). LSG can be performed by newly trained surgeons proctored by senior tutors. At least 50 cases are needed to meet global benchmark cut-offs and few more cases may be required to reach the plateau of the learning curve.

Abstract
BACKGROUND Single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) is a bariatric procedure based on the standard duodenal switch surgery. It was first introduced in 2007 as a procedure for individuals with clinically severe obesity. Till date, primary SADI-S has not been used on Chinese with diabetes and body mass index (BMI) < 35 kg/m2. OBJECTIVES Here, we account the use of this novel surgery in Chinese with diabetes and BMI < 35 kg/m2. METHODS All relevant medical information, involving patients with diabetes and BMI < 35 kg/m2, who received primary SADI-S at Beijing Shijitan Hospital from June 2017 to December 2018, was retrospectively assessed. RESULTS Twenty-six patients were selected for evaluation, and all of them completed a 2-year follow-up. The age, diabetic duration, and preoperative BMI were 35.5 (range 20-63) years, 3.5 (range 0.5-18) years, and 34.40 (range 28.74-34.96) kg/m2, respectively.
