RESUMEN
Obesity poses significant challenges, necessitating comprehensive strategies for effective intervention. Bariatric Surgery (BS) has emerged as a crucial therapeutic approach, demonstrating success in weight loss and comorbidity improvement. This study aimed to evaluate the outcomes of BS in a cohort of 48 Uruguayan patients and investigate the interplay between BS and clinical and metabolic features, with a specific focus on FSTL1, an emerging biomarker associated with obesity and inflammation. We quantitatively analyzed BS outcomes and constructed linear models to identify variables impacting BS success. The study revealed the effectiveness of BS in improving metabolic and clinical parameters. Importantly, variables correlating with BS success were identified, with higher pre-surgical FSTL1 levels associated with an increased effect of BS on BMI reduction. FSTL1 levels were measured from patient plasma using an ELISA kit pre-surgery and six months after. This research, despite limitations of a small sample size and limited follow-up time, contributes valuable insights into understanding and predicting the success of BS, highlighting the potential role of FSTL1 as a useful biomarker in obesity.

Long-term postoperative complications of metabolic and bariatric surgery (MBS) are more frequent than those of primary surgery. Robotic-assisted procedures offer several advantages over traditional laparoscopy, but there are limited data. A retrospective study of 29 patients who underwent a revisional robotic-assisted Roux-en-Y gastric bypass (RRYGB) in a Tertiary Level Hospital. Variables included were demographics, causes for revision, operative details, complications, and weight loss outcomes up to 54 month post-RRYGB. Causes for conversion were weight loss failure (WLF), weight regain (WR), Gastroesophageal Reflux Disease (GERD), or Joint Pain (JP). We assessed 29 patients. Causes for conversion included WLF (34%), WR (15%), WR with GERD (20%), GERD (24%), and JP (3%). Initial BMI was 53.43 kg/m2 ± 8.75. Mean length of hospital stay (LOS) was 2 days. Total operative time was 126 min. ± 43.45. Excess weight loss at 1 year post-surgery was 82.66% (p < 0.0001), with mean BMI of 30.93 kg/m2 (p < 0.001). At 3 years, mean %EWL was 71.26% and a mean BMI 33.81 kg/m2 (p < 0.0001). At 4.5 years, mean %EWL was 59.29% and mean BMI 37.27 kg/m2 (p < 0.0001). One complication (8%) was found (jejunojejunal stenosis). There was no mortality. The initial experience with RRYGB shows acceptable outcomes, including low morbidity, no mortality, excellent weight loss after the revisional surgery, and promising reduction in operative times, with important implications on reduction of the total cost of the procedure.

Obesity is a highly prevalent disease with numerous complications. Both intensive medical treatment with the use of pharmacological drugs and bariatric surgery are current options. The objective of this meta-analysis was to compare, in the long-term, intensive medical treatment and surgery based on twelve parameters related to weight loss, cardiovascular and endocrine changes. A review of the literature was conducted in accordance with the PRISMA guidelines (PROSPERO: CRD42021265637). The literature screening was done from inception to October 2023 through PubMed, EMBASE and Web of Science databases. We included randomized clinical trials that had separate groups for medical treatment and bariatric surgery as an intervention for obesity. The risk of bias was assessed through RoB2. A meta-analysis was performed with measures of heterogeneity and publication bias. Subgroup analysis for each surgery type was performed. Data is presented as forest-plots. Reviewers independently identified 6719 articles and 6 papers with a total 427 patients were included. All studies were randomized controlled trials, three had a follow up of 5 years and two had a follow up of 10 years. Both groups demonstrated statistical significance for most parameters studied. Surgery was superior for weight loss (- 22.05 kg [- 28.86; - 15.23), total cholesterol (- 0.88 [- 1.59; - 0.17]), triglycerides (- 0.70 [- 0.82; - 0.59]), HDL (0.12 [0.02; 0.23]), systolic pressure (- 4.49 [- 7.65; - 1.33]), diastolic pressure (- 2.28 [- 4.25; - 0.31]), Hb glycated (- 0.97 [- 1.31; - 0.62]), HOMA IR (- 2.94; [- 3.52; - 2.35]) and cardiovascular risk (- 0.08; [- 0.10; - 0.05]). Patient in the surgical treatment group had better long term outcomes when compared to the non-surgical group for most clinical parameters.

Preoperative management of patients living with severe obesity can be challenging; in this context, the preoperative weight loss may help to obtain better outcomes and less morbidity for bariatric surgery. Therefore, we evaluated the effectiveness of GLP-1 analogue Liraglutide in preoperative weight loss. We performed a single-center, quasi-experimental prospective study. Eligible participants were adults in preoperative management for bariatric-metabolic surgery with body-mass index ≥ 48 kg/m2. All patients were assigned liraglutide treatment, with an initial dose of 0.6 mg subcutaneous per day, the dose was increased each week until reaching 3.0 mg for 12 weeks. Weight loss and body composition were evaluated monthly using bioelectric impedance (BIA) (InBody 770 Scale®). We analyzed data using descriptive statistics, central tendency measures and dispersion for quantitative variables and absolute and relative frequencies for qualitative variables. A total of 37 individuals were included in this study, 28 (76%) were female and 9 (24%) were males, with an average age of 44 years. About the BMI, 19 patients (51%) had a BMI > 50 kg/m2, 10 (27%) > 40 kg/m2 and 8 (22%) > 60 kg/m2; with a total average BMI of 56.04 kg/m2. The initial weight was 147.4 ± 14.9 kg which decreased to 139.3 ± 16.8 kg; after 3 months of liraglutide administration. A total of 35 patients had some degree of weight loss (94.6%), while 2 (5.40%) had no weight changes. The total weight loss was 5.50% at 3 months of liraglutide treatment. Liraglutide could be an effective adjuvant therapy for preoperative weight loss in patients living with severe obesity.

La obesidad en la infancia y adolescencia es un problema de salud mundial que ha ido en aumento, esto es preocupante no sólo por el riesgo de comorbilidades cardiovasculares, sino que también las psicosociales. La cirugía bariátrica se ha convertido en una alternativa para los casos de obesidad severa en adolescentes. Se trata de un método invasivo que requiere evaluación cuidadosa, no sólo en el aspecto físico, sino que también en el psicológico y social. El objetivo de este trabajo es conocer la evidencia disponible sobre las consecuencias que conlleva la cirugía bariátrica en adolescentes. Se realizó una búsqueda en la literatura en base de datos como PubMed, ScienceDirect y Scopus, utilizando palabras clave como "cirugía bariátrica", "obesidad en adolescentes", "efectos psicosociales" y "salud mental". Se han identificado diversos efectos negativos, entre los cuales destacan las deficiencias nutricionales que afectan al sistema nervioso central, los impactos en la salud mental y el riesgo de psicopatología. Sin embargo, la mayor cantidad de información e investigación se centra en los efectos positivos de la cirugía bariátrica. Aún faltan estudios en población adolescente, especialmente de carácter prospectivo y documentación de los posibles efectos negativos en la salud.
Obesity in childhood and adolescence is a global health problem that has been on the rise, and it is highly concerning due to the risk of cardiovascular and psychosocial comorbidities. Bariatric surgery has become an alternative for cases of severe obesity in adolescents. It is an invasive method that requires careful evaluation, not only in the physical aspect but also in the psychological and social aspects. The aim of this study is to understand the available evidence regarding the consequences of bariatric surgery in adolescents. A literature search was conducted in databases such as PubMed, ScienceDirect, and Scopus, using keywords such as "bariatric surgery," "obesity in adolescents", "psychosocial effects," and "mental health." Among the negative effects found, complications related to nutritional deficiencies affecting the central nervous system, effects on mental health, and the risk of psychopathology are evident. However, most of the information and research focus on the positive effects of bariatric surgery. There is a lack of studies in the adolescent population, especially those of a prospective nature, and documentation of potential negative health effects.

INTRODUCTION: Bariatric surgery is an effective intervention to reduce obesity and improve associated comorbidities. However, its effects on cognitive function are still the subject of debate. Given that the bioavailability of circulating metabolites can influence brain metabolism and cognitive performance, we aimed to assess the effects of bariatric surgery on plasma metabolic profiles and cognitive performance. METHODS: We recruited 26 women undergoing gastric bypass surgery. We conducted anthropometric assessments and collected plasma samples for metabolomic analysis. A set of 4 cognitive tests were used to evaluate cognitive performance. Participants were reevaluated 1 year post-surgery. RESULTS: After surgery, attention capacity and executive function were improved, while immediate memory had deteriorated. Regarding metabolic profile, reduction of beta-tocopherol and increase of serine, glutamic acid, butanoic acid, and glycolic acid were observed. To better understand the relationship between cognitive function and metabolites, a cluster analysis was conducted to identify more homogeneous subgroups based on the cognitive performance. We identified cluster 1, which did not show changes in cognitive performance after surgery, and cluster 2, which showed improved attention and executive function, but reduced performance in the immediate memory test. Thus, cluster 2 was more homogeneous group that replicated the results of non-clustered subjects. Analysis of the metabolic profile of cluster 2 confirmed serine, glutamic acid, and glycolic acid as potential metabolites associated with cognitive performance. CONCLUSIONS: Metabolites identified in this study have potential for biomarkers and alternative therapeutic target to prevent obesity-related cognitive decline. KEY POINTS: ⢠Attention capacity and executive function were improved 12 months post bariatric surgery. ⢠Immediate memory was worsened 12 months post bariatric surgery. ⢠Serine, glutamic acid, and glycolic acid are potential metabolites linked to the alteration of cognitive performance.

INTRODUCCIÓN: Más de 600 mil personas en Chile viven con obesidad mórbida. La incorporación de intervenciones terapéuticas eficaces, seguras y costo-efectivas es crítica para los sistemas de salud y esquemas de aseguramiento. En el año 2022 se incorporaron al arancel de modalidad de libre elección del Fondo Nacional de Salud dos códigos de pago asociado a diagnóstico para cirugía bariátrica: gástrico y manga gástrica. El objetivo fue caracterizar la ejecución del programa de mecanismo de pago tipo pago asociado a diagnóstico de cirugía bariátrica en su primer año de implementación. MÉTODOS: Estudio descriptivo y observacional de abordaje pragmático de la ejecución nacional del pago asociado a diagnóstico en cirugía bariátrica. Se examinaron variables de caracterización sociodemográfica (sexo, tramos etarios y tramos del Fondo nacional de Salud) y caracterización de cirugías según código desagregadas por prestador público o privado, periodo de emisión, gasto unitario, copago, y préstamos médicos, entre marzo y diciembre de 2022. RESULTADOS: Se registraron n = 13 118 cirugías (45,81% versus 54,19% manga), de las cuales n = 2424 (18,48%) emplearon préstamos médicos. Un 85,01% (p = 0,01) de los procedimientos fueron en mujeres; en personas entre 35 y 39 años (20,15%); y 45,12% en beneficiarios del tramo B. El 99,21% de las cirugías se realizó en prestadores privados. Diez de estos concentraron el 50% de la actividad (rango n = 1200 a 426 cirugías anuales; n = 4,8 a 1,7 cirugías por día hábil). El gasto total del programa fue $71 626 948 350 CLP, explicando un 5,04% de la actividad total del Programa nacional de Pago Asociado a Diagnóstico. CONCLUSIONES: La implementación de este bono para cirugía bariátrica benefició a más de 13 mil personas que viven con obesidad, mayormente mujeres, en edades productivas, y con capacidad de compra. Como estrategia de equidad, independientemente de la vía de acceso mediante el bono, será importante cautelar la actividad en la red pública.
INTRODUCTION: More than 600 thousand people in Chile live with morbid obesity. Effective, safe, cost-effective therapeutic interventions are critical for healthcare systems and insurance schemes. In 2022, two bundled payment codes for bariatric surgery (gastric bypass and gastric sleeve) were incorporated into the National Health Fund's free-choice modality fee scheme. The objective was to characterize the execution of this payment mechanism program associated with bariatric surgery diagnosis in its first year of implementation.More than six hundred thousand people in Chile are estimated to live with morbid obesity. Effective, safe, cost-effective therapeutic interventions are critical for health systems and insurance schemes. In 2022, FONASA incorporated two Bariatric Surgery codes into the Free Choice Modality: Gastric Bypass and Sleeve Gastrectomy. Our objective was to characterize the execution of the Bariatric Surgery Bundled Payment Program in its first year of implementation. METHODS: Descriptive and observational study of the pragmatic approach of the national execution of the payment associated with diagnosis in bariatric surgery. We examined sociodemographic variables (sex, age brackets, and National Health Fund tranches) and characterization of surgeries by code broken down by public or private provider, period of issue, unit cost, co-payment, and medical loans between March and December 2022. RESULTS: We recorded n = 13 118 surgeries (45.81% bypass versus 54.19% sleeve), of which n = 2424 (18.48%) used medical loans. A total of 85.01% (p = 0.01) of the procedures were in women, in people between 35 and 39 years of age (20.15%), and 45.12% in beneficiaries of tranche B. Private providers performed a total of 99.21% of the surgeries. Ten accounted for 50% of the activity (range n = 1200 to 426 surgeries per year; n = 4.8 to 1.7 surgeries per working day). Total program expenditure was $71 626 948 350 CLP, accounting for 5.04% of the total activity of the national Diagnosis Associated Payment Program. CONCLUSIONS: The implementation of this bariatric surgery voucher benefited more than 13 thousand people living with obesity, mostly women of productive ages and with purchasing capacity. As an equity strategy, regardless of the access route through the voucher, it will be important to safeguard the activity in the public network.

BACKGROUND: Metabolic and bariatric surgery (MBS) is the preferred method to achieve significant weight loss in patients with Obesity Class V (BMI > 60 kg/m2). However, there is no consensus regarding the best procedure(s) for this population. Additionally, these patients will likely have a higher risk of complications and mortality. The aim of this study was to achieve a consensus among a global panel of expert bariatric surgeons using a modified Delphi methodology. METHODS: A total of 36 recognized opinion-makers and highly experienced metabolic and bariatric surgeons participated in the present Delphi consensus. 81 statements on preoperative management, selection of the procedure, perioperative management, weight loss parameters, follow-up, and metabolic outcomes were voted on in two rounds. A consensus was considered reached when an agreement of ≥ 70% of experts' votes was achieved. RESULTS: A total of 54 out of 81 statements reached consensus. Remarkably, more than 90% of the experts agreed that patients should be notified of the greater risk of complications, the possibility of modifications to the surgical procedure, and the early start of chemical thromboprophylaxis. Regarding the choice of the procedure, SADI-S, RYGB, and OAGB were the top 3 preferred operations. However, no consensus was reached on the limb length in these operations. CONCLUSION: This study represents the first attempt to reach consensus on the choice of procedures as well as perioperative management in patients with obesity class V. Although overall consensus was reached in different areas, more research is needed to better serve this high-risk population.

BACKGROUND: To evaluate the feasibility of an abbreviated focus-assessed transthoracic echocardiography protocol in morbidly obese patients. The purpose of this study was to evaluate whether good images could be obtained from this particularly difficult group of patients for whom acoustic imaging is often poor. Heart imaging could be helpful for cardiopulmonary screening and real-time monitoring. METHODS: The study included 186 morbidly obese patients, who underwent laparoscopic bariatric surgery. The mean patient age was 32 years (range 21-52), and there were 95 males. The parasternal long and short axes and apical 4 and 5 chambers were evaluated. RESULTS: In 95% of the patients, at least one view was obtained. In 78%, two views were obtained, and in 31% of the patients, all views and measurements could be performed. CONCLUSION: In obese patients, a modified focused echocardiography examination performed by anesthesiologists in the intraoperative period of morbid obese patients is feasible. The image quality was sufficient to undergo interpretation.

Introduction: Sleeve gastrectomy with jejunal bypass (SGJB) has been used as a bariatric/metabolic procedure since 2003, in the search for a simpler than other standard techniques and as effective as them. The jejunal-ileal anastomosis can deliver food directly to the hindgut where incretins are secreted. This procedure has gained popularity around the globe and has been studied in rat models as in humans, especially in South America and Asia. In this review, we present the details of the original surgical technique SGJB, summarized all the publications of the procedure, discuss possible advantages and disadvantages, and provide scientific information to look for the real place between bariatric/metabolic procedures. Methods: With 20 years of experience performing the original SGJB, the authors present the details of the procedure. Results: The SGJB consists of a traditional sleeve with the addition of a jejunal bypass. The jejunum is transected 20-30 cm distally to the ligament of Treitz. Then, the biliopancreatic limb is anastomosed to restore transit 250-300 cm distal to the jejunum transection. This way, the ileum gets in contact with partially digested food with the subsequent production of incretins. Conclusion: In this article, we describe the original Alamo technique of SGJB. It is important to clarify the technical details since many publications have presented different lengths of the defunctionalized jejunal limb. Also, the SGJB has been categorized in the "sleeve plus" procedures and its promising outcomes should rapidly position it as an alternative metabolic surgery.

BACKGROUND: Obesity is a chronic disease associated with adverse outcomes and its prevalence is increasing, which makes it a concern. One of the obesity treatment options is bariatric surgery, which effectively reduces calorie absorption and total body mass, but its effects on physical activity (PA) levels need to be clarified, considering the protective effect of the PA against cardiovascular disease, independently of the weight loss alone. OBJECTIVES: To carry out a systematic review and meta-analysis of observational studies that evaluated PA in pre- and post-bariatric surgery periods through objective evaluation. METHODS: A systematic search was carried out following the PRISMA criteria of studies with adult individuals who underwent bariatric surgery and were objectively evaluated for PA pre- and post-surgery. Studies with interventions were excluded. RESULTS: A total of 419 records were found, and after excluding duplicates and applying the eligibility criteria, 10 studies remained. This meta-analysis found a significant increase in the steps by day (MD = 1340; 95% CI = 933.90; 1745.35, p < 0.001) and the light physical activity level (MD = 16.8 min/day; 95% CI = 2.60; 30.98, p = 0.02), but not in moderate to vigorous physical activity (MD = 0.24; 95% CI = -0.08; 1.57, p = 0.92). CONCLUSIONS: Patients undergoing bariatric surgery increased their steps by day and light physical activity but did not increase moderate to vigorous physical activity.

Sleeve gastrectomy (SG) is the most common bariatric surgery worldwide and has shown to cause de novo or worsen symptoms of gastroesophageal reflux disease (GERD). Esophageal motility and physiology studies are mandatory in bariatric and foregut centers. The predisposing factors in post-SG patients are disruption of His angle, resection of gastric fold and gastric fundus, increased gastric pressure, resection of the gastric antrum, cutting of the sling fibers and pyloric spasm. There are symptomatic complications due to sleeve morphology as torsion, incisura angularis stenosis, kinking and dilated fundus. In this article, we present recommendations, surgical technique and patient selection flow diagram for SG and avoid de novo or worsening GERD.

INTRODUCTION: At the beginning of the pandemic, studies showed a higher risk of severe surgical complications and mortality among patients with perioperative SARS-CoV-2 infection, which led to the suspension of elective surgery. Confinement and lockdown measures were shown to be associated with weight gain and less access to medical and surgical care in patients with obesity, with negative health consequences. To evaluate the safety of bariatric surgery during the pandemic, we compared 30-day complications between patients who underwent bariatric surgery immediately before with those who underwent bariatric surgery during the opening phase of the pandemic. METHODS: Observational analytical study of a non-concurrent cohort of patients who underwent bariatric surgery in 2 periods: pre-pandemic March 1 to December 31, 2019, and pandemic March 1 to December 31, 2020. Surgical complications were defined using the Clavien-Dindo classification. RESULTS: Pre-pandemic and pandemic groups included 256 and 202 patients who underwent primary bariatric surgery, respectively. The mean age was 37.6 + 10.3 years. The overall complication rate during the first 30 days of discharge was 7.42%. No differences between groups were observed in severe complications (pre-pandemic 1.56% vs. pandemic 1.98%, p: 0.58). No mortality was reported. Overall 30-day readmission was 3.28% with no differences between groups. CONCLUSION: The findings of this study did not find a difference in the rate of severe complications, nor also we report severe COVID-19 complications in this high-risk population. During the pandemic, with appropriately implemented protocol, the resumption of bariatric surgery is possible with no increased risk for patients.

BACKGROUND: Vitamin, mineral, and metabolic deficiencies occur in the postoperative period of bariatric surgery, in the short and long term, and are worrisome intercurrences. AIMS: To evaluate the association of serum vitamin D levels with the lipid profile in obese patients undergoing bariatric surgery. METHODS: Case series of patients assisted from 2010 to 2018, in a private hospital of medium and high complexity, who underwent bariatric surgery using sleeve gastrectomy or Roux-en-Y gastric bypass techniques, monitored by the same surgeon. Sociodemographic, clinical, laboratory, and anthropometric data were collected preoperatively and at 6, 12, and 24 months after surgery. RESULTS: A total of 156 individuals, mostly female (75.6%) were monitored. The most frequent comorbidities were hepatic steatosis (76.3%) and hypertension (48.27). Regarding preoperative vitamin D levels, only 18.9% of the population had a satisfactory level (≥30 ng/mL). There was a reduction in weight and an improvement in the lipid profile after surgery. Significant correlations were observed between the lipid profile and vitamin D concentration only in the sample submitted to the Roux-en-Y gastric bypass technique: negative correlation between total cholesterol and vitamin D two years after surgery; positive correlation between triglycerides and vitamin D one year after surgery; and negative correlation between high-density lipoprotein and vitamin D two years post-surgery. CONCLUSIONS: It is essential to routinely monitor vitamin D levels and lipid profile pre- and postoperatively in order to avoid damage associated with this vitamin deficiency.

INTRODUCTION: obesity is one of the most common diseases worldwide, and the most effective treatment to it is the bariatric surgery. One of the negative impacts of this procedure is the body dysmorphia caused by overhanging skin. In Brazil, the national health system - Sistema Único de Sáude (SUS) - provide body contouring surgery to treat post-bariatric patients, since 2007. This article aims to describe the Brazilian public health approach to post bariatric patients and perform an analyze in the Brazilian health care database. METHODS: in Brazilian Health System database, a search for the post-bariatric procedures performed between 2007 to 2021 was done. The variables analyzed were geographic location, year, mean days of hospitalization, death, and mortality rate. Also, we evaluated the number of bariatric procedures done in the same period. Statistical analysis was performed using the Student-t and the chi-square tests and p-value <0.5 was considered significant. RESULTS: a total of 12,717 plastic surgery procedures in post bariatric patients were done, with a national prevalence of 13.8%. Dermolipectomy was the most performed procedure, with 6,719. The years of 2020 and 2021 suffered a decreased of 64.3% and 70.9% in the number of surgeries (p<0,001). Bariatric Procedures had a high rate and a higher percentage of growth comparing to post bariatric surgery (p<0,001), totalizing 93,589 surgeries. CONCLUSIONS: Brazil had a significant number of body contouring surgery, however with a low prevalence. Dermoliepctomy was the most common procedure performed. We could notice a significant impact of COVID pandemic in those procedures .
