Resultados cardiometabólicos de largo plazo tras cirugía bariátrica: control de comorbilidades, pérdida y reganancia de peso a los 5 años de seguimiento / Long-term cardiometabolic results after bariatric surgery: Control of comorbidities, weight loss and regain at 5 years of follow-up

Introducción. La cirugía bariátrica y metabólica (CBM) es efectiva en lograr pérdida de peso a corto plazo. Sin embargo, existe evidencia limitada en desenlaces clínicos y metabólicos a largo plazo. Métodos. Estudio longitudinal retrospectivo con pacientes llevados a baipás gástrico en Y de Roux (BGYR) o gastrectomía en manga (MG) por laparoscopia en Bogotá, D.C., Colombia, entre 2013 y 2021. El cambio de peso, control de comorbilidades y resultados metabólicos se recopilaron al inicio del estudio, 3, 6 y 12 meses después de cirugía, y anualmente hasta el quinto año. Las tasas de control de comorbilidades se evaluaron mediante la prueba Kaplan-Meier. Se utilizó un modelo de riesgos proporcionales de Cox para evaluar el efecto de covariables en la reganancia de peso. Resultados. De 1092 pacientes con CBM (71,4 % MG y 28,6 % BGYR), 67 % eran mujeres, con mediana de edad 48 años e índice de masa corporal de 35,5 Kg/m2. Después de cinco años de seguimiento, la tasa de control en diabetes mellitus fue 65,5 %, en hipertensión 56,6 % y en dislipidemia 43,6 %. La tasa de reganancia de peso fue 28 %, sin diferencias entre MG vs BGYR (p=0,482). El tiempo promedio hasta peso nadir fue 14 meses. La edad al momento de CBM fue el mejor predictor independiente de reganancia (HR=1,02, IC95% 1,01-1,04), pero con efecto clínico modesto. Conclusión. La CBM es segura y muestra beneficios a largo plazo en la pérdida de peso y control de comorbilidades en población colombiana.

Introduction. Bariatric and metabolic surgery (BMS) has shown its efficacy in achieving short-term weight loss. However, there is limited evidence regarding long-term clinical and metabolic outcomes. Methods. Retrospective longitudinal study with patients who underwent laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) interventions in Bogotá, Colombia, between 2013 and 2021. Weight change, comorbidity control, and metabolic outcomes were collected at the onset, 3-, 6-, and 12-month post-surgery, and annually up to the fifth year. Comorbidity control rates were assessed using the Kaplan-Meier test. A Cox proportional hazards model was used to evaluate the effect of covariates on weight regain. Results. Of 1092 patients with BMS (71.4% SG and 28.6% RYGB), 67% were women, with a median age of 48 years, BMI 35.5 kg/m2. After five years of follow-up, the control rate in diabetes mellitus was 65.5%, in hypertension 56.6%, and dyslipidemia 43.6%. The weight regain rate was 28% with no differences between SG vs RYGB (p=0.482). The mean time to nadir weight was 14 months. Age at the time of BMS was the best independent predictor of weight regain (HR=1.02, 95%CI: 1.01-1.04), but with a modest clinical effect. Conclusion. BMS is safe and shows long-term benefits in weight loss and control of comorbidities in Colombian population.

Cirugía bariátrica: resultados clínicos en términos de pérdida de peso y resolución de comorbilidades / Bariatric surgery: Clinical outcomes in terms of weight loss and resolution of comorbidities

Introducción. La cirugía bariátrica es una estrategia válida de tratamiento en obesidad severa.

Estudio descriptivo de tipo analítico que incluyó pacientes con obesidad grados II y III. Se analizaron variables demográficas y perioperatorias, y las comorbilidades asociadas a la obesidad. La reducción del peso se evaluó con el porcentaje de pérdida del exceso de peso. Se realizó un análisis descriptivo univariado, usando medianas, rangos intercuartílicos, frecuencias y proporciones. Se usaron las pruebas de U de Mann-Whitney y Chi cuadrado para el análisis de grupos. Un valor de p<0,05 fue considerado estadísticamente significativo. Resultados. Fueron incluidos 201 pacientes. La mediana del porcentaje de pérdida del exceso de peso a 18 meses fue de 77,4 % para el grupo de baipás gástrico en Y de Roux vs 69,5 % para el grupo de manga gástrica (p=0,14). La mayoría de los pacientes presentaron resolución o mejoría de la hipertensión arterial (76 %), diabetes mellitus (80 %), dislipidemia (73 %), apnea del sueño (79 %) y artropatías (94 %), sin diferencia significativa según la técnica quirúrgica empleada. La tasa de complicaciones mayores fue del 1,9 %. No se presentó mortalidad. La mediana de seguimiento fue 28 meses. Conclusión. El baipás gástrico en Y de Roux y la manga gástrica son procedimientos muy seguros y efectivos para la reducción del exceso de peso y la resolución de las comorbilidades asociadas a la obesidad

Introduction. Bariatric surgery is a valid strategy of treatment for severe obesity. The aim of this study is to evaluate weight loss and resolution of comorbidities comparing two procedures, Roux-en-Y gastric bypass and sleeve gastrectomy. Methods. Descriptive study of analytical type that included patients with obesity grades II and III. Demographic and perioperative variables were analyzed. The weight reduction was evaluated among others with the percentage of excess of body weight loss. Comorbidities associated with obesity were also analyzed. A univariate descriptive analysis was performed, using medians, interquartile ranges, frequencies, and proportions. The Mann-Whitney U and Chi squared tests were used for analysis of groups. A value of p <0.05 was considered statistically significant. Median follow-up was 28 months. Results. A total of 201 patients were included in the analysis. The median percentage of excess of body weight loss at 18 months was 77.4% for Roux-en-Y gastric bypass group vs 69.5% for sleeve gastrectomy group (p=0.14). The majority of patients presented resolution or improvement of hypertension (76%), diabetes mellitus (80%), dyslipidemia (73%), sleep apnea (79%), and arthropathy (94%), without significant differences according to the surgical technique used. Major complication rate was 1.9%. There was not mortality. The median follow-up was 28 months. Conclusion. Roux-en-Y gastric bypass and sleeve gastrectomy are both very safe and effective procedures for excess weight reduction and resolution of comorbidities associated with obesity

Factores de riesgo asociados a la pérdida insuficiente o ganancia significativa de peso en pacientes sometidos a cirugía bariátrica / Risk factors associated with insufficient weight loss or significant weight gain in patients undergone bariatric surgery

Introducción. La cirugía bariátrica es efectiva para inducir una rápida pérdida del exceso de peso, pero existen dudas sobre la duración de este efecto a largo plazo. Este estudio buscaba identificar la proporción de pacientes operados que presentaron una pérdida insuficiente o una ganancia significativa de peso y los posibles factores relacionados. Métodos. Estudio de cohorte retrospectivo en pacientes adultos sometidos a cirugía bariátrica. Se describieron variables demográficas y clínicas. Se realizó un análisis multivariado para identificar factores relacionados con un peso fuera de metas posterior a la cirugía. Resultados. Se incluyeron 187 pacientes, 117 con baipás gástrico y 70 con manga gástrica. La mediana de índice de masa corporal preoperatorio fue 41,3 kg/m2 y postoperatorio de 28,8 kg/m2. El 94,7 % de los pacientes en ambos grupos logró una adecuada pérdida del exceso de peso. La ganancia de peso mayor del 20 % se presentó en el 43,5 % de los pacientes, siendo mayor en el grupo de manga gástrica (p<0,004). Los factores independientes para ganancia de peso fueron el sexo masculino (OR 5,5), cirugía tipo manga gástrica (OR 3,4), síndrome de apnea del sueño (OR 2,9) y enfermedad mental medicada (OR 2,8). Conclusión. La cirugía bariátrica produce una pérdida del exceso de peso suficiente en casi la totalidad de los pacientes, pero un buen número recuperan peso luego de 3 años. Los principales factores asociados a ganancia de peso son el sexo masculino y la cirugía tipo manga gástrica

Introduction. Bariatric surgery is highly effective in inducing rapid excess body weight loss but there are doubts about its effect on long-term. This study seeks to identify the number of patients that underwent bariatric surgery who present insufficient weight loss or significant weight gain and the possible related factors. Methods. Retrospective cohort study of adult patients who underwent bariatric surgery. Demographic and clinical variables are described. A multivariate analysis was performed to identify factors related to patient weight outside the set goals postoperatively. Results. 187 patients were included (117 gastric bypass, 70 gastric sleeve). The median preoperative body mass index was 41m/kg2 and 28.8m/kg2 postoperatively. 94.7% of the patients in both groups achieved adequate excess body weight loss. Weight gain (>20%) occurred in 43.5% of the patients, with the probability being higher in the gastric sleeve group (p<0.004). Independent factors for weight gain were male gender (OR 5.5), gastric sleeve surgery (OR 3.4), sleep apnea syndrome (OR 2.9), and mental illness under treatment (OR 2.8). Conclusions. Bariatric surgery produces sufficient loss of excess weight in almost all patients, but a good number of them regain weight after 3 years. The main factors associated with weight gain are male gender and gastric sleeve surgery

Baipás gástrico versus manga gástrica para el controlde diabetes tipo 2 en pacientes obesos / Gastric bypass versus gastric sleeve for the management of type 2 diabetes in obese patients

Introducción. La diabetes mellitus tipo 2 y la obesidad son enfermedades con alta prevalencia, gran morbi-mortalidad y elevados costos en salud. La cirugía bariátrica ha demostrado efectividad para inducir pérdida de peso y un control adecuado de la glicemia. Métodos. Estudio observacional analítico retrospectivo, realizado entre 2014 y 2019 en una institución de alta complejidad. Se incluyeron pacientes prediabéticos y diabéticos sometidos a cirugía bariátrica tipo baipás gástrico en Y-de-Roux o manga gástrica. Se analizaron la mejoría o resolución de la diabetes y la pérdida del exceso de peso a los 6, 12, 24 y 36 meses luego de la cirugía. Resultados. Se incluyeron 103 pacientes en el estudio, 45 pacientes diabéticos y 58 pacientes prediabéticos. La única variable perioperatoria con diferencia estadísticamente significativa fue el tiempo quirúrgico mayor en el baipás (70 vs. 47,5 minutos; p<0,001). La pérdida de exceso de peso fue mayor en el baipás. Los pacientes diabéticos sometidos a baipás tuvieron un mayor porcentaje de resolución o control comparados con los sometidos a manga gástrica. En los pacientes prediabéticos hubo resolución en ambos grupos luego de 24 meses de seguimiento. Conclusión. El baipás gástrico y la manga gástrica presentan excelentes resultados en cuanto a pérdida de peso y control metabólico en pacientes con diabetes mellitus tipo 2 y prediabetes, pero en nuestros pacientes se lograron resultados superiores en ambos aspectos con el baipás gástrico

Introduction. Type 2 diabetes mellitus and obesity are diseases with high prevalence, high morbidity and mortality and high health costs. Bariatric surgery has proven effective in inducing weight loss and adequate glycemic control. Methods. Retrospective analytical observational study conducted between 2014 and 2019 in a high-complex institution. Prediabetic and diabetic patients undergoing Roux-en-Y gastric bypass or gastric sleeve were included; analyzing the improvement or resolution of diabetes and the loss of excess weight at 6, 12, 24 and 36 months after surgery. Results. One-hundred and three patients were included in the study, 45 diabetic patients and 58 pre-diabetic patients. The only perioperative variable with a statistically significant difference was the longer surgical time in the bypass (70 vs. 47.5 min; p<0.001). Loss of excess weight was always greater in bypass. Diabetic patients who underwent bypass had a higher percentage of resolution or control compared to those who underwent the sleeve procedure. In pre-diabetic patients, there was 100% resolution in both groups after 24 months of follow-up. Conclusion. Gastric bypass and gastric sleeve present excellent results in terms of weight loss and metabolic control in patients with type 2 diabetes mellitus and pre-diabetes, but superior results in both aspects were achieved with the first technique in our patients

Abstract Introduction. Obesity is defined as the excess of adipose tissue that deteriorates quality of life and is harmful to health. Its treatment is performed in a multidisciplinary way that ensures weight loss. The high worldwide prevalence and incidence in adolescent patients requires therapeutic interventions that are effective and safe. Bariatric surgery, as a set of surgical procedures, guarantees these characteristics, which is why it has become a valid and effective therapeutic option in patients who do not respond to conventional treatments. Objective. To determine the behavior of weight loss in patients undergoing bariatric surgery at the Hernando Moncaleano Perdomo University Hospital in Neiva, Colombia, in the years 2013 to 2016. Materials and methods. Observational, cross-sectional, retrospective study including a group of patients managed with bariatric surgery in the years 2013 to 2016 at a third level of care hospital. Results. There were 86 patients intervened with bariatric surgery, where 74.4% (64) received laparoscopic gastric bypass (LGB) and 25.6 % (22) laparoscopic gastric sleeve (LGS); 80.2 % were women with an average age of 36 years, all belonging to the subsidized Colombian health regime (64%). The most common comorbidities were osteoarticular disease (82%), arterial hypertension(36%) and type 2 diabetes (29%). There were significant differences (p = 0.003) for the initial and final BMI between two groups. It was determined that the group with the best "optimal" result in terms of %EWL (percentage of excess weight loss) equal or greater than 50% per year, was the LGB (p = 0.026). Finally it was determined that the greatest weight loss was achieved in the group of patients undergoing LGB, with a statistically significant difference; however it is necessary to carry out analytic studies that confirm these results Conclusions: A progressive decrease in weight was evidenced in both groups in the follow-up year; however the LGBgroup achieved better statistically significant results in terms of %EWL per year compared to the LGS group, data that correlates with the global trend in terms of this type of interventions.

New technique for obesity surgery: internal gastric plication technique using intragastric single-port (igs-igp) in experimental model / Nova técnica para a cirurgia da obesidade: plicatura intragástrica single port intragástrico (igs-igp) reduz em média 51% do volume gástrico em modelo experimental

ABSTRACT Background: Bariatric surgery is currently the most effective method to ameliorate co-morbidities as consequence of morbidly obese patients with BMI over 35 kg/m2. Endoscopic techniques have been developed to treat patients with mild obesity and ameliorate comorbidities, but endoscopic skills are needed, beside the costs of the devices. Aim: To report a new technique for internal gastric plication using an intragastric single port device in an experimental swine model. Methods: Twenty experiments using fresh pig cadaver stomachs in a laparoscopic trainer were performed. The procedure was performed as follow in ten pigs: 1) volume measure; 2) insufflation of the stomach with CO2; 3) extroversion of the stomach through the simulator and installation of the single port device (Gelpoint Applied Mini) through a gastrotomy close to the pylorus; 4) performance of four intragastric handsewn 4-point sutures with Prolene 2-0, from the gastric fundus to the antrum; 5) after the performance, the residual volume was measured. Sleeve gastrectomy was also performed in further ten pigs and pre- and post-procedure gastric volume were measured. Results: The internal gastric plication technique was performed successfully in the ten swine experiments. The mean procedure time was 27±4 min. It produced a reduction of gastric volume of a mean of 51%, and sleeve gastrectomy, a mean of 90% in this swine model. Conclusion: The internal gastric plication technique using an intragastric single port device required few skills to perform, had low operative time and achieved good reduction (51%) of gastric volume in an in vitro experimental model.

RESUMO Racional: A cirurgia bariátrica é atualmente o método mais efetivo para melhorar as co-morbidades decorrentes da obesidade mórbida com IMC acima de 35 kg/m2. Técnicas endoscópicas foram desenvolvidas para tratar pacientes com obesidade leve e melhorar as comorbidades, mas habilidades endoscópicas são necessárias, além dos custos. Objetivo: Relatar uma nova técnica para a plicatura gástrica interna utilizando um dispositivo intragástrico de portal único em modelo experimental de suínos. Métodos: Foram realizados 20 experimentos utilizando estômagos de cadáver de porco fresco em um instrutor laparoscópico. O procedimento foi realizado da seguinte forma em dez porcos: 1) medida de volume; 2) insuflação do estômago com CO2; 3) extroversão do estômago através do simulador e instalação do dispositivo de uma única via (Gelpoint Applied Mini) através de uma gastrotomia próxima ao piloro; 4) realização de quatro suturas de quatro pontos intra-gástricas com Prolene 2-0, desde o fundo gástrico até o antro; 5) medição do volume residual. A gastrectomia vertical foi também realizada em mais dez suínos e o volume gástrico pré e pós-procedimento foi medido. Resultados: A técnica de plicatura gástrica interna foi realizada com sucesso nos dez experimentos com suínos. O tempo médio do procedimento foi de 27±4 min. Produziu redução do volume gástrico em média de 51%, e a gastrectomia vertical em média de 90% neste modelo suíno. Conclusão: A técnica de plicatura gástrica interna, utilizando um dispositivo intragástrico de uma única via, exigiu poucas habilidades para ser realizada, teve baixo tempo operatório e obteve boa redução (51%) do volume gástrico em um modelo experimental in vitro.

ENDOSCOPIC SLEEVE GASTROPLASTY - MINIMALLY INVASIVE THERAPY FOR PRIMARY OBESITY TREATMENT / GASTROPLASTIA VERTICAL ENDOSCÓPICA - TERAPÊUTICA MINIMAMENTE INVASIVA PARA TRATAMENTO PRIMÁRIO DA OBESIDADE

ABSTRACT Background: Less invasive and complex procedures have been developed to treat obesity. The successful use of Endoscopic Sleeve Gastroplasty using OverStitch(r) (Apollo Endosurgery, Austin, Texas, USA) has been reported in the literature. Aim: Present technical details of the procedure and its surgical/ endoscopic preliminary outcome. Method: The device was used to perform plications along the greater curvature of the stomach, creating a tubulization similar to a sleeve gastrectomy. Result: A male patient with a BMI of 35.17 kg/m2 underwent the procedure, with successful achievement of four plications, and preservation of gastric fundus. The procedure was successfully performed in 50 minutes, time without bleeding or other complications. The patient presented mild abdominal pain and good acceptance of liquid diet. Conclusions: The endoscopic gastroplasty procedure was safe, with acceptable technical viability, short in duration and without early complications.

RESUMO Racional: Procedimentos menos invasivos e complexos têm sido desenvolvidos para o tratamento da obesidade. A gastroplastia vertical endoscópica com uso de OverStitch(r) (Apollo Endosurgery, Austin, TX, EUA) já foi relatada com sucesso na literatura. Objetivo: Apresentar detalhes técnicos do procedimento e seu resultado cirúrgico/endoscópico preliminar. Método: O equipamento foi utilizado para realizar plicaturas ao longo da grande curvatura gástrica, objetivando tubulização do estômago semelhante a gastrectomia vertical. Resultado: O método foi aplicado em paciente com IMC 35,17 kg/m2, sendo realizadas quatro plicaturas, preservando o fundo gástrico. O procedimento foi realizado com sucesso em 50 min, sem sangramento ou outras complicações. O paciente evoluiu com dor abdominal leve, e teve boa aceitação de dieta líquida. Conclusão: A realização da gastroplastia endoscópica foi segura, com viabilidade técnica aceitável e reprodutível, com curto tempo de procedimento, sem complicações precoces.

Gastroplastia vertical com desvio jejunoileal: novo procedimento técnico / Vertical gastroplasty with jejunoileal bypass: new technical procedure

INTRODUÇÃO: A gastroplastia vertical é procedimento técnico cada vez mais utilizado no tratamento cirúrgico da obesidade mórbida, sendo empregado isoladamente ou como tempo cirúrgico do duodenal switch ou da bipartição intestinal (técnica de Santoro). Quando empregada isoladamente tem apenas caráter restritivo. MÉTODO: É proposta a associação do desvio jejunoileal à gastroplastia vertical, no sentido de conferir um componente metabólico ao procedimento e eventualmente potencializá-lo a médio e longo prazos. Foram operados oito pacientes com obesidade mórbida após a retirada da banda gástrica ajustável ou como procedimento primário associado à gastroplastia vertical e desvio jejunoileal através de anastomose laterolateral entre o jejuno a 80 cm do ângulo dudeno jejunal e o íleo a 120 cm da válvula ileocecal, por videolaparoscopia. RESULTADOS: Os pacientes evoluíram sem qualquer intercorrência tanto no trans como no pós-operatório imediato, e nos meses que se seguiram. A evolução do IMC médio, mostrou redução expressiva indo de 39,57 kg/m² para 28 kg/m². Nenhum paciente referiu diarréia ou qualquer quadro disabsortivo no período estudado. CONCLUSÃO: Pode-se oferecer nova opção terapêutica, com ação restritiva e metabólica, na qual não existem os inconvenientes do desvio do trânsito duodenal com todas suas consequências.

INTRODUCTION: Vertical gastroplasty is increasingly used in the surgical treatment of morbid obesity, being used alone or as part of the duodenal switch surgery or even in intestinal bipartition (Santoro technique). When used alone has only a restrictive character. METHOD: Is proposed association of jejunoileal bypass to vertical gastroplasty, in order to give a metabolic component to the procedure and eventually empower it to medium and long term. Eight morbidly obese patients were operated after removal of adjustable gastric band or as a primary procedure associated to vertical banded gastroplasty with jejunoileal bypass laterolateral and anastomosis between the jejunum 80 cm from duodenojejunal angle and the ileum at 120 cm from ileocecal valve, by laparoscopy. RESULTS: The patients presented themselves without complications both in trans or in the immediate postoperative period, and also in the months that followed. The evolution BMI showed a significant reduction ranging from 39.57 kg/m² to 28 kg/m². No patient reported diarrhea or malabsorptive disorder in the period. CONCLUSION: It can be offered a new therapeutic option, with restraining and metabolic aspects, in which there are no consequences as the ones founded in procedures with duodenal diversion or intestinal transit alterations.
