Tracing the Scientific Legacy: Bibliometric Analysis of LATAM Research in Bariatric Surgery for 33 Years.

INTRODUCTION: Metabolic and bariatric surgery (MBS) has experienced considerable growth, addressing the challenges of obesity and its complications. The lack of a comprehensive bibliometric analysis in Latin America motivates this study, highlighting the need to understand the evolution of research in this area and its impact on clinical decision-making and health policies. METHODOLOGY: A cross-sectional bibliometric study was carried out using the Scopus database. A structured search strategy was designed to identify articles related to bariatric surgery with authors affiliated with Latin American countries. Inclusion and exclusion criteria were applied, followed by a descriptive and bibliometric analysis of the scientific production found. RESULTS: A total of 3553 documents published between 1991 and 2024 were included. There was an annual growth of 11%, with an average age of documents of 7.5 years. A concentration was observed in some countries, notably Brazil, Mexico, and Chile. Although scientific output increased, the average number of citations per article showed a downward trend since 2003. DISCUSSION: Despite the growth in scientific production, the quality and relevance of research is questioned, especially given the decrease in the impact received. It highlights the lack of meaningful regional collaboration, which could limit the sharing of knowledge and resources. Questions are raised about gaps in research capacity and the economic and development implications are discussed. CONCLUSIONS: This study provides valuable information to strengthen future research in bariatric surgery in Latin America. It highlights the importance of promoting regional and international collaboration and improving research training in countries with less participation. Clinical intervention strategies can benefit from better understanding research trends and adopting evidence-based practices in a more informed manner.

Condutas na ritidoplastia e apontamentos histológicos na pele da face do paciente pós-bariátrica / Rhytidoplasty practices and histological notes for the facial skin of post-bariatric patients

Introdução: O número de pacientes classificados com sobrepeso ou obesos e, com isso, dos pacientes pós-bariátricas vem aumentando, gerando uma demanda por ritidoplastias neste perfil de público. O objetivo é expor a rotina e táticas cirúrgicas em um hospital de ensino, o perfil destes pacientes, além de um comparativo superficial histológico da pele, tecido celular subcutâneo e SMAS, entre os pacientes pós e não pós-bariátrica. Métodos: Foi realizado revisão de dados do centro cirúrgico e de prontuário entre os anos de 2012 e 2016 em um hospital público na cidade de Goiânia-GO, com levantamento de 32 casos. Resultados: A tática de ritidoplastia utilizada nos pacientes pós-bariátrica não apresenta grandes diferenças entre a utilizada nos pacientes não pós-bariátrica. A análise histopatológica das amostras colhidas evidenciou diferenças marcantes entre os pacientes pós e não pós-bariátrica. Conclusão: Percebeu-se que a técnica operatória na ritidoplastia do paciente pós-bariátrica sustentou detalhes específicos, com resultado cirúrgico pós-operatório satisfatório, uma pele de pior qualidade histológica, com complicações perioperatórias dentro do esperado e com necessidade de maiores estudos para avaliar durabilidade do procedimento.

Introduction: The number of patients classified as overweight or obese has resulted in an increased number of post-bariatric patients, generating a demand for rhytidoplasty in this public profile. The objective is to expose the routine and surgical tactics in a teaching hospital, patient profiles, subcutaneous cellular tissue, and the superficial musculoaponeurotic system are compared between post-bariatric and non-post-bariatric patients, as well as histological superficial comparison of the skin. Methods: A review of the data of 32 cases treated in 2012­2016 was conducted in a public hospital in Goiânia-GO. Results: The tactics of rhytidoplasty used in post-bariatric patients do not differ significantly from those used in nonpost- bariatric patients. A histopathological analysis of the collected samples showed marked differences between post-bariatric and non-post-bariatric patients. Conclusion: The surgical technique of rhytidoplasty of post-bariatric patients sustained specific details with satisfactory postoperative surgical results, skin with worse histological quality, perioperative complications within the expected range, and the need for further studies to assess the procedure's durability

Improvement of Body Composition and Quality of Life Following Intragastric Balloon.

BACKGROUND: The aim is to evaluate the effects of IGB in overweight or class I obese patients, by analyzing body composition and quality of life (QOL). METHODS: Prospective study including patients with BMI 27-34.9 kg/m2.body composition analysis (BCA) was performed before IGB implantation and its removal, after 6 months of treatment. QOL was assessed by the Short Form 36 (SF-36) Health Survey at baseline and after treatment. RESULTS: Forty patients were included in this study, but four were excluded. The total weight decreased by 12.29 kg after 6 months of use of IGB, which corresponds to loss of 13.69% of the total weight. There was a significant reduction in body fat mass and fat area. QOL improved in all eight sections analyzed (p < 0.001 to 0.041): functional capacity, physical aspects, pain, general health status, vitality, social aspects, emotional aspects, and mental health. CONCLUSIONS: IGB induces not only weight loss but changes in body composition through the reduction of body fat mass and fat area. Furthermore, it improves QOL.

Cirugía bariátrica: generalidades / Bariatric surgery: general

La obesidad es considerada una epidemia en la actualidad. Es definida por la OMS como un índice de masa corporal (IMC) mayor o igual a 30. Se han realizado numerosos esfuerzos para determinar distintos tratamientos que permitan disminuir tanto la prevalencia de dicha enfermedad como las complicaciones asociadas a la misma.La cirugía bariátrica marca el inicio de una nueva era, en la que es posible reducir la morbi-mortalidad asociada a la obesidad. Específicamente se ha demostrado remisión en algunos casos de diabetes, tendencia a la mejoría en pacientes con NAFLD, NASH y reflujo gastroesofágico, así como franca mejoría a nivel cardiovascular. El propósito principal de este artículo es discutir el impacto de la cirugía bariátrica sobre dichas comorbilidades y sobre mortalidad, además las técnicas quirúrgicas, complicaciones y criterios de selección, con el fin de definir cuáles pacientes se benefician de este abordaje.

Obesity is defined as a body mass index greater or equal to 30, nowadays it is considered an epidemic. Numerous efforts have been carried on in order to define treatments that will effectively reduce the prevalence and complications of this condition. Bariatric surgery came to mark the beginning to a new era in this field; it demonstrated a reduction in morbi-mortality in patients with obesity. It has proven to induce remission in patients with diabetes, to improve NAFLD, NASH and GERD, and to be associated to a definite cardiovascular benefit. The main purpose of this article is to discuss the impact that bariatric surgery has over these comorbidities as well as on mortality. Surgical techniques, complications, and selection criteria are also addressed with the objective of defining which patients will benefit from this intervention.

Manga gástrica laparoscópica. Revisión detallada / Laparoscopic sleeve gastrectomy

Resumen La cirugía bariátrica es una rama de la medicina que se dedica al tratamiento de la obesidad y sus posibles comorbilidades a través de procedimientos quirúrgicos. Presentamos la historia y varios aspectos de la manga gástrica laparoscópica a través de 20 años. La reducción de peso se logra aquí por varios mecanismos: uno es la reducción del volumen estomacal y otro es la menor secreción de la hormona ghrelina; lo que promueve una saciedad más rápida y una reducción del apetito. Karamankos S.N. encontraron un mayor porcentaje en la apérdida del exceso de peso con manga gástrica que con bypass gástrico en un seguimiento a 1 año (69,7 ± 14,6% contra 60,5 ± 10,7%). En un metaanálisis publicado en 2011, Padwal R. y cols. concluyeron que existe una mayor disminución de índice de masa corporal en pacientes sometidos a manga gástrica que en bypass gástrico de −10,1 kg/m2 y -9 kg/m2 respectivamente.

Abstract Bariatric surgery is a medical specialty dedicated to the treatment of obesity and its comorbidities through surgical procedures. We present a detailed collection on the history and evolution of laparoscopic sleeve gastrectomy over the course of 20 years. The gastric sleeve induces weight loss by several mechanisms. It significantly reduces gastric chamber size and decreases the secretion of the hormone called ghrelin, thus promoting quicker satiety and decreasing appetite. Karamankos S.N. found a greater percentage of excess-weight loss with gastric sleeve than with bypass in a 1-year follow-up (69,7% ± 14,6% versus 60,5% ± 10,7%). A 2011 meta-analysis by Padwal R. et al. concluded that there is a greater decrease in body mass index in patients undergoing sleeve gastrectomy than with gastric bypass, -10,1 kg/m2 and -9 kg/m2, respectively.
