RESUMO
Objective:To explore the effects of multi-disciplinary team (MDT) participation for residency training in bariatric and metabolic surgery.Methods:A questionnaire was designed considering patient benefits, doctor benefits, and interviewees' background and recognition of MDT. The questionnaire was used to survey 48 residents who rotated to the department of gastrointestinal surgery and participated in the management of patients undergoing bariatric and metabolic surgery in Peking University Third Hospital from February to October 2023. According to the frequency of MDT participation, the residents were divided into two groups (<5 times and ≥5 times). They were evaluated by five superior surgeons, and the scores of the two groups were compared using the independent samples t test. Results:All the 48 residents completed the questionnaire survey. Only 16 residents (33.33%) had been exposed to the knowledge of bariatric and metabolic surgery, and most of the respondents believed that participating in MDT could improve their professional competence ( n=42, 87.50%) and special English proficiency ( n=30, 62.50%). The group of MDT participation ≥5 times had significantly higher scores of knowledge of internal medicine [(7.42±1.09) vs. (5.16±1.28)], knowledge of anesthesia and critical care medicine [(7.11±0.85) vs. (4.93±0.99)], perioperative management [(7.08±0.67) vs. (4.97±1.21)], laparoscopic skills [(6.43±0.83) vs. (4.99±0.65)], and professional knowledge of general surgery [(6.46±0.86) vs. (5.87±0.51)] compared with the group of MDT participation <5 times (all P<0.05). Conclusions:MDT participation in bariatric and metabolic surgery can help residents quickly understand and master relevant knowledge, which is of great significance for increasing the personnel reserve of bariatric and metabolic surgery.
RESUMO
Obesity is a global epidemic. According to the World Health Organization (WHO), it is an abnormal or excessive accumulation of fat that can harm health. Its incidence is increasing alarmingly in developing countries. It is also a significant risk factor for developing chronic diseases such as type 2 diabetes mellitus, arterial hypertension, coronary disease, non-alcoholic fatty liver disease, and musculoskeletal disorders such as osteoarthritis. Furthermore, associations have been found between obesity and the development of prostate, liver, gallbladder, kidney, colon, endometrial, breast, and ovarian cancer. Bariatric and metabolic surgery is the most effective treatment for morbid obesity and its comorbidities. This surgery can reduce general mortality by 40% at ten years due to cardiovascular outcomes, diabetes, or cancer and improve metabolic diseases such as type 2 diabetes.
La obesidad es una epidemia global, según la Organización Mundial de la Salud (OMS) se define como una acumulación anormal o excesiva de grasa que puede ser perjudicial para la salud, su incidencia está aumentando de forma alarmante en los países en desarrollo. Asimismo, es un factor de riesgo importante para el desarrollo de enfermedades crónicas como la diabetes mellitus tipo 2, hipertensión arterial, enfermedad coronaria, enfermedad del hígado graso no alcohólico y trastornos musculoesqueléticos como la osteoartritis; además, se han encontrado asociaciones entre la obesidad y el desarrollo del cáncer de próstata, hígado, vesícula biliar, riñón, colon, endometrio, mama y ovarios. La cirugía bariátrica y metabólica es el tratamiento más eficaz para la obesidad mórbida y sus comorbilidades, esta cirugía puede reducir la mortalidad general en un 40% a los diez años por desenlaces cardiovasculares, diabetes o cáncer, como también mejorar enfermedades metabólicas como la diabetes tipo 2.
RESUMO
Objective:To identify latent classes of impulsivity among metabolic surgery patients based on latent class model and determine the relationship between the latent classes of impulsivity and anxiety and depression symptoms.Methods:The 272 obese patients (97 males and 175 females) undergoing metabolic surgery in the Department of Weight Loss and Metabolic of Qilu Hospital of Shandong University from October 2021 to August 2022 were included. The average age was (30.50±6.70) years old and the average body mass index (BMI) was (42.54±6.97) kg/m 2. The survey contents included: demographic and sociological data; impulsivity; anxiety symptoms; depression symptoms. The latent profile analysis (LPA) of impulsivity among metabolic surgery patients was conducted using Mplus 8.3. The comparison of anxiety and depression between different latent classes was analyzed by the binary logistic regression analysis using SPSS 25.0. Results:The research subjects in terms of impulsivity were divided into 3 latent classes: "low impulsivity group" accounted for 32.7%; "high impulsivity group" accounted for 51.8%; "high sensation seeking/positive urgency/negative urgency group" accounted for 15.4%. The binary logistic regression analysis results showed that taking "low impulsivity group" for reference, the risk of positive anxiety and depression was 2.06 ( OR=2.06, 95% CI: 1.08-3.93) and 4.13 ( OR=4.13, 95% CI: 2.17-7.87) times higher for "high impulsivity group" patients than for "low impulsivity group" patients; the risk of positive anxiety and depression was 3.25 ( OR=3.25, 95% CI: 1.42-7.44) and 4.16 ( OR=4.16, 95% CI: 1.82-9.50) times higher for "high sensation seeking/positive urgency/negative urgency group" patients than for "low impulsivity group" patients. Conclusions:The impulsivity of metabolic surgery patients showed obvious heterogeneity and could be divided into 3 types: "low impulsivity group" , "high impulsivity group" , and "high sensation seeking/positive urgency/negative urgency group" . Compared with "low impulsivity group" , "high impulsivity group" and "high sensation seeking/positive urgency/negative urgency group" metabolic surgery patients are most likely to develop anxiety and depressive symptoms.
RESUMO
Obesity has emerged as a significant public health concern with profound implications for human well-being. Bariatric metabolic surgery can significantly reduce the weight of patients with severe obesity and improve the related complications, and has been widely used in clinical practice. With the growth of surgical amount, the occurrence of postoperative hypoglycemia, in addition to surgery-related adverse events, has gradually attracted clinical attention. Post-bariatric hypoglycemia (PBH) occurs 6-12 months after bariatric metabolic surgery. It is characterized by blood glucose levels ≤2.8~3.3 mmol/L within 1-3 hours after a meal, accompanied by symptoms of sympathetic nervous system activation and even neuroglycopenic symptoms. Limited epidemiological investigations suggest that the prevalence of PBH ranges from 0.2% to 44.2%. Notably, severe and recurrent hypoglycemic events have deleterious implications for patients, significantly compromising their quality of life and posing a potential threat to their life safety. Consequently, the management of PBH warrants comprehensive clinical attention.
RESUMO
Bariatric surgery is the most effective treatment for patients with severe obesity, which can significantly improve the metabolic disorders, especially type 2 diabetes mellitus. Bariatric and metabolic surgery is the latest and fastest-growing branch of surgery, with the types of procedure and other novel treatment modalities are still evolving and in progress. The authors summarize the recent advancement related to novel bariatric and metabolic surgery in the treat-ment of morbid obesity and type 2 diabetes mellitus in recent years through literature search, which can be divided into the following three parts: (1) novel surgical procedures and new guideline of indication. Sleeve gastrectomy and Roux-en-Y gastric bypass are the most performed bariatric surgery. Duodenal switch or the variant of one anastomosis duodenal ileostomy are also accredited procedures but been less performed. One anastomosis gastric bypass is the most recently accredited bariatric surgical procedures with better safety profile and weight loss efficacy than most of the procedures. For other novel procedures, bipartition procedure may be the next accredited proce-dure. A new worldwide guideline is recently launched and the indication for bariatric surgery is lowered BMI 27.5 kg/m 2 for Asian. (2) The effect and mechanism of bariatric surgery. Bariatric surgery can significantly reduce the incidence of cardiovascular disease and mortality in obese patients. The main beneficiary group is patients with diabetes mellitus. Along with the recent basic research and the success of new gut hormone related drugs, the mechanism of bariatric surgery can be mostly attributed to gut hormonal effect, however, gastric volume still play an important role. (3) Novel obesity treatment modalities. Endoscopic obesity treatment has a major progress in the success of endoscopic gastroplasty by endoscopic suturing designs. More noteworthy is the development of new intestinal hormone drug therapy, which can achieve a weight loss of 14% in one year by injec-ting once a week glucagon-like peptide-1 preparation, and then combining two or three intestinal hormone drugs can achieve a weight loss of 24% in one year, which is close to the effectiveness of bariatric surgery. Pharmacologic treatment of obesity is very promising and expected. With the increasing severity of obesity and diabetes mellitus in the world, in addition to the explosive develo-pment of bariatric and metabolic surgery in recent years, many new surgical methods and new treatments, especially new and effective intestinal hormone related therapeutic drugs, have been developed. The success of bariatric and metabolic surgery depends on a multidisciplinary team with rich clinical experience: precise preoperative planning and comprehensive postoperative manage-ment, as well as patient understanding and cooperation, in order to achieve the best results.
RESUMO
At present, obesity and overweight patients are increasing year by year in the world. Bariatric surgery is the most effective method for treating obesity at present. Due to its high risk, large trauma, irreversible operation, high cost and patient preference, the overall acceptance degree is not high at present. With the development of endoscopic technology and materials and equipment, various surgical methods emerge one after another. They are less invasive, reversible and similar to traditional bariatric surgery in weight loss effect. They are more and more widely used in obesity and metabolism. Depending on the site of the endoscopic intervention: The authors review the advances in endoscopic bariatric surgery for obesity, including the different principles of surgery and the effects of bariatric surgery on different sites.
RESUMO
The rapid development of bariatric and metabolic surgery in China in the past 20 years is due to the economic development and needs of lifestyle changes, as well as the unremit-ting exploration of surgeons. Although bariatric and metabolic surgery is facing good development opportunities, its specialized development is far from enough, non-standard surgery still exists in clinical work, specialist training and standardization are in the initial stage, and follow-up is also a serious challenge for bariatric and metabolic surgery. The authors believe that on the basis of solid progress in normalization and standardization, bariatric and metabolic surgery will welcome a bright future.
RESUMO
The effect of bariatric and metabolic surgery on obesity with type 2 diabetes mellitus has been widely recognized, so the guidelines for the treatment and management of diabetes mellitus are constantly revised. In order to balance the effect and safety of surgery, innovative surgical methods continue to emerge. But for the effect on diabetes mellitus, high-level clinical researches are still needed to provide more evidence. For postoperative remission and the mechanism of bariatric and metabolic surgery to alleviate diabetes, and the application of bariatric and metabolic surgery in the treatment of type 1 diabetes mellitus, new researches have emerged constantly. Based on the clinical practices and domestic and foreign literatures, the authors discuss the application of bariatric and metabolic surgery in the treatment of diabetes mellitus.
RESUMO
Objective:To investigate the application value of 3D printed model in hemostasis training for laparoscopic sleeve gastrectomy.Methods:The retrospective and descriptive study was conducted. Data were collected from six surgeons who participated in hemostasis training for laparoscopic sleeve gastrectomy using 3D printed model at Zhejiang Provincial People′s Hospital in July 2023. All participants were male, aged (33.5±9.9)years. A 3D printed model simulating bleeding during laparoscopic sleeve gastrectomy was created using hydrogel. Videos were recorded to document the surgeons′ hemostasis techniques and outcomes during laparoscopic sleeve gastrectomy. Two external expert reviewers blindly assessed the training videos using the objective structured assess-ment of technical skills (OSATS) scoring system to evaluate mesentery mobilization, vessel exposure, vessel clipping and bleeding after vessel clipping. Observation indicators: (1) face validity and content validity of the 3D printed model; (2) validity verification of the 3D printed model. Measurement data with normal distribution were represented as Mean± SD. Comparison between groups was conducted using the t test. Results:(1) Face validity and content validity of the 3D printed model. The surgeons′ scores for overall impression, fidelity, texture, appearance, workspace and tactile similarity of the 3D printed model were 4.5±0.6, 4.0±0.6, 3.7±0.5, 4.2±0.8, 3.8±0.8 and 4.2±0.4, respectively. The surgeons′ scores for similarity to real scenarios, operation convenience, learning curve shortening and operation skills improving, patient risk reduction, trainee′s interest enhancing, confidence increasing and recommendation for promotion were 4.0±0.6, 4.2±0.8, 4.3±0.8, 4.3±0.5, 4.3±0.5, 4.0±0.6 and 4.8±0.4, respectively. (2) Validity verification of the 3D printed model. The OSATS scores and operation time to treat bleeding during laparoscopic sleeve gastrectomy for expert surgeons were 18.7±0.6 and (125±12)seconds, respectively, versus 13.7±1.5 and (212±51)seconds for junior doctors, showing significant differences between the two groups ( t=5.30, -2.89, P<0.05). Conclusion:The 3D printed model effectively simulates bleeding scenarios during laparoscopic sleeve gastrectomy and distinguishes between different technical levels of expertise.
RESUMO
In more than half a century of the development of bariatric metabolic surgery, a variety of classic surgical methods have been formulated. However, the improvement and innovation of bariatric metabolic surgery has never stopped. The replacement of new and old surgical methods in clinical application and development reflects the vitality and progress in the field of bariatric metabolic surgery, and also promotes the development of bariatric metabolic surgery to the best balance between benefits and risks. In the early stages, studies in metabolic surgery are more inclined to confirm the efficacy, safety and mechanism of classical procedures. In recent years, metabolic surgeons around the world have become more inclined to focus on the exploration and innovation of new procedures. In addition, the improvement of biliopancreatic diversion with duodenal switch and the sleeve gastrectomy plus procedures have gradually become hot spots for surgical innovation. However, the new techniques are diverse, scattered and partially overlapping. The authors make a comment on this content, in order to provide assistance to clinical and scientific research.

RESUMO
Objective:To investigate the application value of right minimal invasive three-port technique of laparoscopic sleeve gastrectomy (RMIT-LSG) for the treatment of obesity.Methods:The retrospective and descriptive study was conducted. The clinical data of 66 obesity patients who underwent RMIT-LSG in the Sir Run Run Shaw Hospital of Zhejiang University School of Medicine from January to October 2021 were collected. There were 15 males and 51 females, aged 28.5(range, 16.0?54.0)years. The body mass index (BMI) of the 66 patients was (36.9±4.3)kg/m 2. There were 20 of the 66 patients combined with type 2 diabetes. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted using outpatient examination or the WeChat to detect postoperative recovery of patients including body mass changing, BMI and complications 6 months after operation. The follow-up was up to December 2021. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1) Surgical situations. All the 66 patients underwent RMIT-LSG successfully, without conversion to laparotomy or changing surgical method. The operation time and the volume of intraoperative blood loss of the 66 patients were (132±22)minutes and (14±8)mL, respectively. (2) Postoperative situations. The time to postoperative initial out-of-bed activities, time to postoperative first flatus, time to postoperative initial water intake, time to postoperative initial liquid food intake and duration of postoperative hospital stay of the 66 patients were (15±6)hours, (1.80±0.60)days, (1.00±0.20)days, (2.00±0.20)days and (3.40±0.60)days, respectively. Of the 66 patients, one case underwent post-operative abdominal hemorrhage at postoperative day 1 and received a second surgery for hemostasis. The patient with postoperative abdominal hemorrhage and other 65 patients recovered well without gastroparesis, gastric fistula, abdominal infection and other complication. (3) Follow-up. All the 66 patients were followed up for 6(range, 1?11)months. All the 66 patients completed the postoperative scar photography at postoperative 1 month, and results of scar photography showed concealed scar with good cosmetic effects. Twenty-seven of the 66 patients were followed up for 6 months after operation, with the weight loss, percentage of weight loss and decrease of BMI were (42±7)kg, 34.8%±2.9%, (14.2±1.9)kg/m 2, respectively. None of the 66 patient had innutrition during the follow-up. Conclusion:The RMIT-LSG is safe and feasible for the treatment of obesity, with a good cosmetic effect of the wound.
RESUMO
Objective:By comparing the changes of metabolic parameters before and after laparoscopic sleeve gastectomy (LSG) in patients with type 2 diabetes mellitus (T2DM) and obesity, the insulin resistance index (HOMA-IR) and atherogenic index of plasma (AIP) were calculated to evaluate the effect of metabolic surgery on insulin resistance and atherosclerosis in patients with type 2 diabetes mellitus (T2DM) and obesity.Methods:LSG treatment were retrospectively analyzed in 54 patients with type 2 diabetes mellitus and obesity, detection of preoperative and postoperative 1 month, 6 month of fasting plasma glucose (FPG), fasting insulin (FINS), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), measuring blood pressure, body weight, calculating body mass index, and according to the steady state evaluation model and the formula for calculating HOMA-IR and AIP. Before and after surgery, paired t test was used, and Pearson correlation analysis and multiple stepwise regression analysis.Results:FPG, FINS, TG, HOMA-IR and AIP were (6.38±2.03) mmol/L and (5.36±1.33) mmol/L, (20.42±25.77) uU/mLand (11.22±3.62) uU/mL, (1.94±2.81) mmol/Land (1.70±2.33) mmol/L, (5.60±7.52) and (2.58±0.80), (0.15±0.27) and (0.08±0.25) ,which were significantly lower than those before surgery ( P<0.05) ,HDL-C was (1.04±0.20) mmol/L and (1.10±0.18) mmol/L at 1 and 6 months after operation, respectively, which was higher than that before operation ( P<0.05) .Preoperative correlation analysis showed that AIP was positively correlated with FPG, TG and HOMA-IR ( P<0.05), and negatively correlated with HDL-C ( P<0.05) .The results of multiple stepwise regression analysis showed that FPG, TG and HDL-C were independent influencing factors of AIP ( P<0.05) . Conclusion:LSG surgery can effectively reduce the blood glucose and lipid levels in patients with type 2 diabetes complicated with obesity, improve insulin resistance and reduce the plasma atherosclerosis index.
RESUMO
Objective:To explore the association of weight loss with diabetes remission after metabolic surgery in patients with type 2 diabetes mellitus(T2DM) for 10 years and more.Methods:Data of T2DM patients with obesity who underwent metabolic surgery in the General Surgery Department & Obesity and Metabolic Disease Center of China-Japan Friendship Hospital from November 2017 to June 2021 were retrospectively collected and analyzed. Remission of diabetes was defined as glycated hemoglobin (HbA1c) < 6.5% or fasting blood glucose < 7.0 mmol/L after discontinuing anti-diabetic medication for more than 3 months. The patients were followed up and divided into two groups according to whether the percentage total weight loss (%TWL) was ≥ 20% or not. The age, sex, body mass index (BMI), fasting C-peptide, and HBA1c were compared between the two groups.Results:Among 65 (28 males and 37 females) patients with T2DM for ≥ 10 years , 50 (76.9%) achieved diabetes remission after a median of 12-month follow-up. 6.2%, 41.5% , 38.5% and 13.8% of the patients achieved %TWL < 10%, 10~20%, 20~30% and ≥ 30% , respectively. The diabetes remission rates were 50%, 63.0%, 92.0% and 88.9%, respectively. Compared with the %TWL < 20% group, the preoperative weight [(95.5±18.8) kg vs (85.5±11.0) kg, P = 0.012] and BMI [(34.4±6.0) vs (30.9±3.3) , P = 0.006] were significantly higher in the %TWL ≥ 20% group, and diabetes remission rates was aslo significantly higher in the %TWL ≥ 20% group (91.2% vs 61.3%, P = 0.010) . After adjusting for age, preoperative BMI, fasting C-peptide and duration of T2DM, Cox multivariate regression analysis showed that %TWL ≥ 20% was independently associated with diabetic remission after metabolic surgery in patients with T2DM for ≥ 10 years (HR = 1.99, 95% CI: 1.03 to 3.83, P = 0.04). Conclusions:More than 70% of patients with T2DM for ≥ 10 years could achieve diabetes remission after metabolic surgery. %TWL ≥ 20% may be one independent factor of diabetes remission in patients with long-duration T2DM.
RESUMO
Objective:To investigate the postoperative changes in levels of 25-hydroxy vitamin D (25-[OH]D], parathyroid hormone (PTH) and other relevant biomarkers in obese patients receiving metabolic surgery and analyze the dynamic changes in relevant biomarkers in the short term (after 3-6 months) and the long term (after 12-24 months).Methods:A total of 96 obese patients who underwent metabolic surgery and received follow-up examinations from January 2018 to January 2020 were included. Baseline and postoperative data were collected, including anthropometric data (height, weight, neck circumference, waistline and hipline) and laboratory test results (fasting glucose, glycated hemoglobin, 25-[OH)D, PTH, serum calcium and serum phosphorus). Body mass index (BMI) and waist-hip ratio were calculated. The anthropometric data were analyzed by repeated measures analysis of variance and laboratory data were compared between groups using t test and Kruskal-Wallis test. Results:96 patients (33 males and 63 females) were included, of whom 49 were complicated with diabetes. Prior to surgery, 79 (79.17%) of the patients had 25-(OH)D deficiency (< 20 μg/L), 16 (16.67%) had 25-(OH)D insufficiency (≥ 20 μg/L and < 30 μg/L) and 23 (23.96%) had high PTH levels (> 70 ng/L). After the surgery, 25-(OH)D level was transiently increased in the short term ( P = 0.01) but declined thereafter in the long term ( P < 0.01) to levels lower than baseline ( P = 0.023). Long-term PTH level was higher than baseline ( P = 0.012), with 11 patients showing PTH levels higher than normal (> 70 ng/L). Serum phosphorus level was increased in both the short term and the long term ( P < 0.01). Conclusions:Obese patients have 25-(OH)D deficiency/insufficiency before metabolic surgery and experience further decrease in the long term after surgery, despite a transient increase. Secondary increase in PTH level occurs in some of the patients after surgery. Long-term nutritional supplements and comprehensive nutritional management play important roles in postoperative management of obese patient.
RESUMO
Analysis of the layout and proportion of classic and innovative surgical procedures of bariatric and metabolic surgery throughout the world, the sleeve gastrectomy is beco-ming the most accepted and respected surgical procedure with its increasingly prominent advan-tages, and its operation number has even exceeded the "gold standard" surgery of the roux-en-Y gastric bypass. This trend is even more pronounced in China. With a small number of physicians lacking experience in gastrointestinal surgery and more and more young physicians joining in the field of bariatric and metabolic surgery, operation related complications and the consequences of insufficient perioperative management experience have occurred successively in clinical practice, such as gastrointestinal leakage, bleeding, lumen and anastomotic stenosis, internal hernia and obstruction, venous thromboembolism, etc. Bariatric and metabolic surgery is a branch of gastro-intestinal surgery, and physicians in the field should have the ability to prevent, predict and manage short- and long-term complications after surgery. The authors believe that through the comprehen-sive evaluation of laboratory indexes, patient signs and related examinations, physicians should have the basic qualities of decisively choosing the surgical timing, choosing the right decision-making, and taking effective measures.
RESUMO
La prevalencia de obesidad y diabetes mellitus se asocia al desarrollo de enfermedad renal crónica y estadios terminales de la misma. En individuos con obesidad se produce un mecanismo de hiperfiltración, probablemente compensatorio para satisfacer la alta demanda metabólica asociada al aumento del peso corporal, con la presencia de proteinuria en individuos sin enfermedad renal. La histopatología muestra una glomeruloesclerosis focal y segmentaria relacionada con la obesidad en un marco de glomerulomegalia. La cirugía metabólica es el medio más efectivo para obtener una pérdida de peso sustancial y persistente. Se ha demostrado la superioridad de la cirugía sobre el tratamiento médico no solo para lograr un mejor control glucémico, sino también para la reducción de los factores de riesgo cardiovascular. Los mecanismos parecen extenderse más allá de la magnitud de la pérdida de peso e incluyen mejoras tanto en los perfiles de incretinas como en la secreción y la sensibilidad a la insulina. El Comité de Nefropatía de la Sociedad Argentina de Diabetes realizó esta revisión sobre los mecanismos involucrados en la obesidad como causa de enfermedad renal o empeoramiento de la misma por diabetes, y los mecanismos a través de los cuales la cirugía bariátrica beneficiaría a los pacientes con diabetes y enfermedad renal crónica en todos los estadios de la misma, así como los controles pre y posquirúrgicos en este tipo de cirugías.
The prevalence of obesity and diabetes mellitus are associated with the development of chronic kidney disease and its terminal stages. In individuals affected by obesity, a probably compensatory hyperfiltration mechanism occurs to satisfy the high metabolic demand associated with increased body weight; it is also associated with the presence and development of proteinuria in individuals without kidney disease. Histopathology shows obesity-related focal and segmental glomerulosclerosis in a setting of glomerulomegaly. Metabolic surgery is the most effective means of obtaining substantial and lasting weight loss. The superiority of surgery over medical treatment has been demonstrated only to achieve better glycemic control, as well as a reduction in cardiovascular risk factors. The mechanisms appear to extend beyond the magnitude of weight loss and include improvements in incretin profiles, insulin secretion, and insulin sensitivity. The Nephropathy Committee of the Argentine Diabetes Society carried out this review on mechanisms involved in obesity as a cause of kidney disease or worsening of kidney disease due to diabetes, the mechanisms by which bariatric surgery would benefit patients with diabetes and kidney disease chronic and its terminal stages, the pre and post-surgical controls that should be performed by patients undergoing this type of surgery
