Managing Low and Moderate Risk Obesity: Insights from a Colombian Reference Center's Experience with Liquid-Filled Intragastric Balloons

Introduction: Liquid-filled intragastric balloons (IGBs) have emerged as a safe and effective option for managing overweight and obesity. However, there is limited information available regarding the implementation of liquid IGBs in individuals with low- and moderate-risk obesity. Objective: The objective of this study was to assess the implementation of liquid IGBs in low- and moderate-risk obese individuals in terms of weight loss, safety, and tolerance at four, six, and twelve months of treatment. Materials and methods: This prospective, descriptive observational study included 109 subjects with low- and moderate-risk obesity (body mass index [BMI] of 30-40 kg/m2), who underwent endoscopic implantation of liquid-filled IGBs. The variables analyzed included sex, age, initial and final weight, percentage of weight loss, and side effects. Results: Out of the 109 subjects, 75.22% were women. The average weight at baseline was 87.22 kg, with an average BMI of 31.59 kg/m2. Three different brands of IGBs were used: Orbera (n=103), Spatz3 (n=3), and Elipse (n=3). The average weight loss showed significant differences when analyzed by months and brands-Ellipse: four months (-4.6 kg), Spatz3: three months (-7 kg), Orbera: six months (15.2 kg), Orbera: twelve months (19.7 kg). The average reduction in BMI achieved was 27.71 kg/m2. The complication rate was 2.75%, with two cases (1.83%) attributed to intolerance (abdominal pain) and one case due to acute appendicitis (0.91%). Conclusions: The findings of this study indicate that liquid-filled IGBs are a safe and effective procedure for managing low- and moderate-risk obesity. A minimum duration of twelve months with an IGB implantation is considered optimal for individuals with low- and moderate-risk obesity.

Introducción: los balones intragástricos (BIG) de llenado líquido han surgido como una opción segura y eficaz para el manejo de sobrepeso y obesidad. En nuestro medio hay poca información acerca de su implementación en obesidad de riesgo bajo y moderado. Objetivo: evaluar la implementación del BIG de contenido líquido en individuos con obesidad de riesgo bajo y moderado en términos de pérdida de peso, seguridad y tolerancia a 4, 6 y 12 meses de tratamiento. Materiales y métodos: estudio observacional prospectivo y descriptivo, se incluyeron a 109 sujetos con obesidad de riesgo bajo y moderado (índice de masa corporal [IMC] de 30 a 40 kg/m2), a quienes se les implantó por vía endoscópica un BIG de llenado líquido. Se analizaron las variables de sexo, edad, peso inicial y final, porcentaje de pérdida de peso y efectos secundarios. Resultados: 109 sujetos, 75,22% correspondieron a mujeres, el peso promedio fue de 87,22 kg, con IMC promedio de 31,59 kg/m2. Se usaron tres marcas (Orbera, n: 103; Spatz, 3, n: 3; y Elipse, n: 3). La pérdida de peso promedio presentó diferencias importantes al analizar por meses y marcas: Elipse: 4 meses (-4,6 kg), Spatz 3: 3 meses (-7 kg), Orbera: 6 meses (15,2 kg), Orbera: 12 meses (19,7 kg). Se logró la reducción del IMC promedio a 27,71 kg/m2. La tasa de complicaciones fue del 2,75%, 2 (1,83%) por intolerancia (dolor abdominal) y una por apendicitis aguda (0,91%). Conclusiones: El BIG de llenado líquido es un procedimiento seguro y eficaz. Un período de implantación del BIG de al menos 12 meses se considera óptimo para obesidad de riesgo bajo y moderado.

The efficacy of liraglutide combined with intragastric balloon on weight loss

SUMMARY OBJECTIVE: Intragastric balloon placement is an effective method for weight reduction. The aim of this study was to evaluate the efficacy of combining liraglutide with intragastric balloon. METHODS: Initially, demographic data of patients such as age, gender, comorbid diseases, adverse events, initial weight, height, body mass index, percent body fat, and waist-hip ratio were collected. Weight, body mass index, percent body fat, and waist-hip ratio were measured in the second, third, fourth, fifth, and sixth months. Then, intragastric balloon was removed and liraglutide was stopped. RESULTS: A total of 50 patients were included in the study, of whom 28 (56%) were in Group A (intragastric balloon) and 22 (44%) were in Group B (plus liraglutide). Weight change at the time of balloon removal was higher in Group B [median weight change 13.8 (7.8 min to 16.8 max) versus 7.9 (4.8 min to 11.8 max); p<0.01]. When the weight, percent body fat, body mass index, and waist-hip ratio changes were compared according to gender, no significant difference was observed in the groups. Comorbid diseases were hypertension in 7 patients (4 in Group A and 3 in Group B) and diabetes in 9 patients (5 in Group A and 4 in Group B). No statistical significance was found. CONCLUSION: Liraglutide has benefits in terms of weight, percent body fat, and body mass index reduction when administered with intragastric balloon.

Pancreatitis aguda asociada a balón intragástrico

Presentamos el caso de una mujer joven con el hábito de dormir en posición decúbito ventral, quien refiere que, tras la colocación de balón intragástrico, inició cuadros repetitivos de dolor abdominal en epigastrio, de aparición nocturna. El más reciente se caracterizó por dolor abdominal súbito e intenso, elevación de enzimas pancreáticas y hallazgos imagenológicos compatibles con pancreatitis aguda. Tras realizar un estudio etiológico sistemático, se descartan otras causas, retirándose el balón intragástrico con inmediato cese de los dolores nocturnos. Se atribuyó la etiología a fenómenos de compresión mecánica provocados por el balón sobre el cuerpo pancreático durante el descanso en decúbito prono. Hacemos notar que el hábito de reposo en la posición decúbito ventral constituiría un potencial factor de riesgo para pancreatitis post-colocación de balón intragástrico, por lo que este factor debe ser tomado en cuenta en la orientación de los candidatos a esta técnica.

We present a clinical case of a young woman with the habit of sleeping in the prone position. She reports that after intragastric balloon placement, she begins with nocturnal episodes of epigastric abdominal pain. The most recent episode was characterized by sudden and intense abdominal pain, elevation of pancreatic enzymes, and imaging findings compatible with acute pancreatitis. After carrying out a systematic approach, other potential causes were ruled out. After removing the intragastric balloon, immediate cessation of the nocturnal episodes of pain was obtained. The etiology was attributed to the mechanical compression phenomena caused by the balloon on the pancreatic body during rest in the prone position. We note that the habit of resting in the prone position would constitute a potential risk factor for acute pancreatitis after intragastric balloon placement, so this factor should be considered when counselling candidates for this technique.

Short term clinical efficacy of intra-gastric balloon on obesity patients with different body mass index / 中华消化外科杂志

Objective:To investigate the short term clinical efficacy of intra-gastric balloon (IGB) on obesity patients with different body mass index (BMI).Methods:The retrospective and descriptive study was conducted. The clinical data of 62 obesity patients with different BMI who were admitted to three medical centers, including 56 cases in the Hurstville Private Hospital, 4 cases in the St George Private Hospital of University of New South Wales and 2 cases in the East Sydney Private Hospital, from January 2017 to December 2021 were collected. There were 15 males and 47 females, aged 45.1(range, 18.0 to 67.0)years, with the BMI of 35.1(range, 27.8 to 48.4)kg/m 2. Of the 62 patients, there were 33 cases with 27 kg/m 2≤BMI<35 kg/m 2 and 29 cases with BMI≥35 kg/m 2. Observation indicators: (1) first operation and postoperative complications; (2) follow-up after first IGB; (3) recurrent IGB and postoperative complications; (4) follow up after recurrent IGB. Follow-up was conducted using outpatient examinations to detect postoperative complications and weight loss effects. Patients were followed up at postoperative 1, 3, 6 month. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M (range). Count data were described as absolute numbers. Results:(1) First opera-tion and postoperative complications. All 62 obesity patients underwent the first IGB successfully. Of the 62 patients, 45 cases had postoperative complications, including 38 cases with gastroesophageal reflux, 12 cases with dysphagia or burping, 9 cases with epigastric pain and 4 cases with nausea. One patient may have multiple complications. Cases with above complications in the 33 cases with 27 kg/m 2≤BMI<35 kg/m 2 and 29 cases with BMI≥35 kg/m 2 were 21, 8, 7, 2 and 17, 4, 2, 2, respectively. (2) Follow-up after first IGB. Of the 62 obesity patients, there were 52, 46 and 38 cases completing followed up at postoperative 1, 3 and 6 month, respectively, including 30, 25,20 cases in patients with 27 kg/m 2≤BMI<35 kg/m 2 and 22, 21, 18 cases in patients with BMI≥35 kg/m 2. Of the 62 obesity patients, there were 15 cases requiring early balloon extraction due to intractable symptoms, inclu-ding 7 cases with ongoing dysphagia or burping, 6 cases with complaining of ineffective weight loss, 1 case with acute right-sided abdominal pain and 1 case with a serendipitous discovery of pregnant. The cumulative weight loss of the 30 cases with 27 kg/m 2≤BMI<35 kg/m 2 and 22 cases with BMI≥35 kg/m 2 at postoperative 1 month was (4.8±3.0)kg and (6.6±2.8)kg, respectively. The above indicator was (6.7±4.4)kg and (10.6±4.8)kg at postoperative 3 month for the 25 cases with 27 kg/m 2≤BMI<35 kg/m 2 and 21 cases with BMI≥35 kg/m 2, and (8.5±4.8)kg and (9.8±3.9)kg at postoperative 6 month for the 20 cases with 27 kg/m 2≤BMI<35 kg/m 2 and 18 cases with BMI≥35 kg/m 2. The percentage of excess weight loss was 53%±26% and 29%±15% at postoperative 6 month and the percentage of total weight loss was 14%±5% and 10%±5% at postoperative 6 month for the 20 cases with 27 kg/m 2≤BMI<35 kg/m 2 and 18 cases with BMI≥35 kg/m 2, respectively. (3) Recurrent IGB and postoperative complications. Of the 38 cases completing the postoperative 6 month followed up after the first IGB, 9 cases with 27 kg/m 2≤BMI<35 kg/m 2 and 7 cases with BMI≥35 kg/m 2 choosing a second IGB immediately after the removal of the first balloon. Cases with postoperative compli-cations, including gastroesophageal reflux, dysphagia or burping, epigastric pain, nausea were 4, 3, 0, 0 in patients with 27 kg/m 2≤BMI<35 kg/m 2 and 4, 0, 2, 1 in patients with BMI≥35 kg/m 2. (4) Follow up after recurrent IGB. All the 16 patients who chosen a second IGB completed the postoperative 6 month followed up, with the cumulative weight loss of (8.8±8.5)kg and (18.9±9.7)kg and the percentage of excess weight loss of 44%±38% and 41%±15% in the 9 cases with 27 kg/m 2≤BMI<35 kg/m 2 and 7 cases with BMI≥35 kg/m 2, respectively. Conclusions:IGB can achieve a good short-term weight loss effects in obesity patients with BMI≥27 kg/m 2. Gastroesophageal reflux, dysphagia or burping, epigastric pain and nausea are common postoperative complications.

Avaliação de perda de peso após o uso de balão intragástrico não ajustável e ajustável / Assessment of weight loss after non-adjustable and adjustable intragastric balloon use

ABSTRACT BACKGROUND: Intragastric balloon (IGB) use is indicated for patients whose BMI precludes the option of bariatric surgery or who need to lose weight prior to undergoing surgery. It is a minimally invasive procedure and currently there are two main models of IGBs in use, the non-adjustable intragastric balloon (NIB), implanted for six months, and the adjustable intragastric balloon (AIB), implanted for up to 12 months. OBJECTIVE: Analyze clinical characteristics between patients receiving non-adjustable gastric balloon and the adjustable (prolonged implantation) intragastric balloon. METHODS: This was a cross-sectional study of 470 patients diagnosed as obese or overweight who had balloon implantation from October 2011 to July 2018. The associations between percentage excess weight loss versus clinical and demographic variables were calculated using the chi-squared test. Independent samples were submitted to the Student's t test to determine the quantitative variables, with a confidence interval of 95%. Calculation of excess weight was based on an estimated ideal weight that would correspond to a BMI of 24.99 kg/m2. RESULTS: A total of 414 patients completed the treatment achieving an average total body weight loss (%TBWL) of 15.4±7 with the NIB and 15.5±9.6 with the AIB. Overweight patients achieved higher excess weight loss (%EWL) values using AIBs (157.2±82.5) and obese patients did so with NIB use (56±29.7). Women achieved higher %EWL values (65.6±62.2) than men (48±27.1). Individuals who attended >4 consultations with a nutritionist (60.8%) achieved TBWL >18%. All of those P-values were <0.001. CONCLUSION: Obese individuals and women registered the greatest weight losses. Overweight patients achieved greater losses using AIB and obese patients did so using NIBs. NIB use was associated with higher EWL percentages. Nutritional accompaniment had a positive impact on the %TBWL.

RESUMO CONTEXTO: O uso do balão intragástrico (BIG) é indicado para pacientes cujo IMC contraindica a cirurgia bariátrica ou que necessitam perder peso antes da cirurgia. É um procedimento minimamente invasivo e atualmente existem dois modelos principais de BIG - o balão intragástrico não ajustável (BINA), implantado por seis meses, e o balão intragástrico ajustável (BIA), por até 12 meses. OBJETIVO: Analisar os fatores associados aos resultados clínicos comparando o uso de balão intragástrico não ajustável com o uso de balão intragástrico ajustável. MÉTODOS: Estudo transversal em 470 pacientes, com sobrepeso ou obesidade, submetidos ao tratamento entre outubro 2011 e julho de 2018. A associação entre as porcentagens da perda de excesso de peso (%PEP) e da perda do peso total (%PPT) com as variáveis demográficas e clínicas foram calculados com o teste qui-quadrado (P<0,05). Foi utilizado o teste t de Student para amostras independentes para comparar variáveis quantitativas, com IC 95%. O cálculo do excesso de peso foi estimado em peso ideal correspondente a um IMC de 24.99 kg/m2. RESULTADOS: Um total de 414 pacientes realizaram o tratamento até o final, com %PPT média de 15,4±7 no BINA e 15,5±9,6 no BIA. Os com sobrepeso apresentaram maiores %PEP no BIA (157,2±82,5) e os obesos maiores %PEP no BINA (56±29,7), com P<0,001. Mulheres (65,6±62,2) apresentaram maiores %PEP do que homens (48±27,1), com P<0,001. Os indivíduos que atenderam a >4 consultas com nutricionista obtiveram %PPT >18% (60,8%), com P<0,001. CONCLUSÃO: Obesos e mulheres tiveram maiores perdas ponderais. Maior perda de peso foi identificada em pacientes com sobrepeso que utilizaram BIA e em obesos os quais utilizaram BINA. O BINA esteve associado com maiores taxas de %PEP. O acompanhamento nutricional impactou positivamente na %PPT.

Esophageal intramural pseudodiverticulosis in a patient with food bolus impaction / Pseudodiverticulosis intramural esofágica en un paciente con impactación de bolo alimentario

Esophageal intramural pseudodiverticulosis is an uncommon esophageal benign disease. The typical finding during endoscopy is the presence of numerous pinhead-sized outpouchings along the esophageal wall. We reported a case of food bolus impaction secondary to esophageal intramural pseudodiverticulosis. A 67-year-old man presented with sudden-onset dysphagia. Multiple tiny orifices were revealed during upper endoscopy. In addition, there were an impacted food bolus and an esophageal web. The patient was treated with balloon dilatation and proton pump inhibitors. As a result the symptoms disappeared completely. Esophageal intramural pseudodiverticulosis is a rare cause of food bolus impaction and its treatment is directed towards the underlying associated conditions as well as the resolution of complications.

La pseudodiverticulosis intramural esofágica es una enfermedad benigna del esófago poco común. El hallazgo típico durante la endoscopia es la presencia de numerosos sáculos del tamaño de una cabeza de alfiler a lo largo de la pared esofágica. Reportamos un caso de impactación de bolo alimentario secundario a pseudodiverticulosis esofágica intramural. Un hombre de 67 años presentó disfagia de aparición repentina. Se encontraron múltiples orificios pequeños en la endoscopia superior. Además, hubo un bolo alimentario impactado y una red esofágica. El paciente fue tratado con dilatación con balón e inhibidores de la bomba de protones. Como resultado, los síntomas desaparecieron por completo. La pseudodiverticulosis intramural esofágica es una causa rara de impactación del bolo alimentario y su tratamiento se dirige a las condiciones asociadas subyacentes, así como a la resolución de complicaciones.

Intragastric balloons in high-risk obese patients in a Brazilian center: initial experience / Balões intragástricos em obesos de alto risco em um centro brasileiro: experiência inicial

ABSTRACT Objective: to assess the short-term efficacy, tolerance and complications in high-risk morbidly obese patients treated with an intragastric balloon as a bridge for surgery. Methods: we conducted a post-hoc analysis study in a Brazilian teaching hospital from 2010 to 2014, with 23 adult patients with a BMI of 48kg/m2, who received a single intragastric air or liquid balloon. We defined efficacy as 10% excess weight loss, and complications, as adverse events consequent to the intragastric balloon diagnosed after the initial accommodative period. We expressed the anthropometric results as means ± standard deviation, comparing the groups with paired T / Student's T tests, when appropriate, with p<0.05 considered statistically significant. Results: the balloons were effective in 91.3% of the patients, remained in situ for an average of 5.5 months and most of them (65.2%) were air-filled, with a mean excess weight loss of 23.7kg±9.7 (excess weight loss 21.7%±8.9) and mean BMI reduction of 8.3kg/m2±3.3. Complications (17.3%) included abdominal discomfort, balloon deflation and late intolerance, without severe cases. Most of the participants (82.7%) did not experience adverse effects. We removed the intragastric balloons in time, without intercurrences, and 52.2% of these patients underwent bariatric surgery within one month. Conclusion: in our center, intragastric balloons can be successfully used as an initial weight loss procedure, with good tolerance and acceptable complications rates.

RESUMO Objetivo: identificar a eficácia em curto prazo, a tolerância e as complicações em obesos mórbidos de alto risco, tratados com balão intragástrico como ponte para cirurgia. Métodos: estudo de análise post-hoc em um hospital acadêmico brasileiro durante o período de 2010 a 2014, de 23 pacientes adultos com IMC de 48kg/m2 que receberam um único balão intragástrico de ar ou líquido. Eficácia foi definida como perda de excesso de peso de 10%, e complicações como eventos adversos consequentes ao balão intragástrico diagnosticados após o período acomodativo inicial. Expressaram-se os resultados antropométricos com média ± desvio padrão, comparando os grupos com testes T Pareado / T de Student, quando apropriado, com p<0,05 considerado estatisticamente significante. Resultados: os balões foram efetivos em 91,3% dos pacientes, permaneceram in situ por em média 5,5 meses e a maioria deles (65,2%) era de ar, com perda média de excesso peso de 23,7kg±9,7 (perda de excesso de peso de 21,7%±8,9) e redução média de IMC de 8,3kg/m2±3,3. As complicações (17,3%) compreenderam desconforto abdominal, deflação do balão e intolerância tardia, sem casos graves. A maioria dos participantes (82,7%) não experimentou efeitos adversos, seus balões intragástricos foram extraídos em tempo, sem intercorrências e 52,2% desses pacientes submeteram-se à cirurgia bariátrica no intervalo de um mês. Conclusão: no nosso centro, balões intragástricos podem ser usados com sucesso como procedimento inicial de perda ponderal, com boa tolerância e taxas aceitáveis de complicações.

Gastric Ulceration and Bleeding with Hemodynamic Instability Caused by an Intragastric Balloon for Weight Loss

Obesity in the United States is a medical crisis with many people attempting to lose weight with caloric restriction. Some patients choose minimally invasive weight loss solutions, such as intragastric balloon systems. These balloon systems were approved by the Federal Drug Administration (FDA) in 2015–2016 and have been considered safe, with minimal side effects. We report a patient with a two-day history of melena, abdominal pain, hypotension, and syncope which developed five months after placement of an intragastric balloon. Esophagogastroduodenoscopy with balloon removal revealed a small 8-mm gastric ulcer in the incisura. This gastric ulcer probably developed secondary to mechanical compression of the stomach mucosa by the gastric balloon which contained 900 mL of saline. The FDA is now investigating five deaths since 2016 associated with these second-generation balloons. Clinicians should be aware of these complications when evaluating patients with gastrointestinal complications, such as bleeding.

Utilização de balão intragástrico e perda de peso em pacientes em um centro de referência no Rio Grande do Sul / Use of intragastric balloon and weight loss in patients at a reference center in Rio Grande do Sul

Objetivo: Estudar a relação entre perda de peso e a utilização de balão intragástrico. Método: Estudo transversal prospectivo desenvolvido com 50 usuários de balão intragástrico em um centro de referência em aparelho digestório no Rio Grande do Sul. Foi calculado o índice de massa corporal (IMC), dividindo-se o peso (quilograma) pela altura (metro) elevada ao quadrado e considerado normal IMC<25; como sobrepeso 25-29,9;IMC 30-34,9 como obesidade grau I; IMC 35-39,9 como obesidade grau II e IMC>40 obesidade grau III, conforme Organização Mundial da Saúde (OMS)/2000. Resultados: Foram avaliados 50 pacientes com estado nutricional entre sobrepeso e obesidade grau III, conforme classificação da OMS/2000. Em relação à porcentagem de perda de peso, observou-se que 46% dos pacientes tiveram uma perda entre 10-15 kg, 24% perda menor que 10 kg, 22% perda entre 15-20 kg e 8% perda maior de 20 kg. Conclusão: Embora a perda média fique entre 15 a 20% do peso inicial, esta perda seja extremamente variável e dependa de vários fatores, como peso inicial, adaptação, volume de preenchimento, disposição emocional para mudanças, adesão ao controle clínico e nutricional, grau de atividade física, metabolismo basal, a motivação e a disciplina para implantar as mudanças são os grandes determinantes deste resultado. Contudo, podemos observar, no presente estudo, evidências sobre a eficácia do tratamento com balão intragástrico em pacientes obesos.(AU)

Objective: To study the relationship between weight loss and use intragastric balloon. Methods: A prospective cross-sectional study was carried out with 50 intragastric balloon users at a reference center in a gastrointestinal tract in RS. The body mass index (BMI) was calculated by dividing the weight (kilogram) by the height (meter) elevated squared and considered normal BMI <25; As overweight 25-29.9; BMI 30-34.9 as obesity grade I; BMI 35-39,9 as obesity grade II and BMI> 40 obesity grade III according to World Health Organization (WHO)/ 2000. Results: Fifty patients with nutritional status between overweight and grade III obesity were evaluated, according to WHO / 2000 classification. Regarding the percentage of weight loss, it was observed that 46% of the patients had a loss between 10-15 kg, 24% a loss less than 10 kg, 22% loss between 15-20 kg and 8% loss greater than 20 kg. Conclusion: Although the average loss is between 15 and 20% of the initial weight, this loss be extremely variable and depends on several factors such as initial weight, adaptation, filling volume, emotional disposition for changes, adherence to clinical and nutritional control, degree of physical activity, basal metabolism, motivation and discipline to implant the changes are the major determinants of this result. However, we can observe in the present study evidence on the efficacy of intragastric balloon treatment in obese patients.(AU)
