INTRAGASTRIC BALLOON AND IMPACT ON WEIGHT LOSS: EXPERIENCE IN QUITO, EQUADOR

BALÃO INTRAGÁSTRICO E IMPACTO NA PERDA DE PESO: EXPERIÊNCIA EM QUITO, EQUADOR

ABSTRACT

BACKGROUND:

Obesity is associated with different medical conditions, such as cardiologic, respiratory, gastrointestinal, and genitourinary, and constitutes a severe health problem.

AIMS:

This study aimed to evaluate the use of intragastric fluid-filled balloon in the reduction of weight and other measurements related to body composition.

METHODS:

This is a retrospective, monocentric study involving all patients who opted for the intragastric balloon Spatz® placement from January 2018 to July 2019, with fulfillment of inclusion and exclusion criteria. The patients were analyzed after 6 and 12 months after the intragastric fluid-filled balloon placed.

RESULTS:

A total of 121 subjects were included in this study, with 83 (68.6%) females and 38 (31.4%) males. The mean age was 36 years and height was 1.64±0.09. Weight mean and standard deviation was 89.85±14.65 kg, and body mass index was 33.05±4.03; body mass index decreased to 29.4 kg/m2 with a mean weight of 79.83 kg, after 12 months of follow-up. There were statistical differences between body mass index and the 12 months in fat percentage, fat-free mass (kg), visceral fat area, and basal metabolic rate. There was a significant variation according to gender, with males having highest reduction. The percentage of excess weight loss was 46.19, and the total weight loss was 9.24 at the end of the study.

CONCLUSIONS:

The study demonstrated a benefit of intragastric fluid-filled balloon on weight loss after 12 months. At the end of treatment, body mass index and the measurements of body composition were significantly lower. Men benefited more than women from the treatment.

INTRODUCTION

Overweight and obesity remain a big public health issue, affecting over one-third of the world's population today2525 Ng M, Fleming T, Robinson M, Thomson B, Graetz N, Margono C, et al. Global, regional, and national prevalence of overweight and obesity in children and adults during 1980-2013: a systematic analysis for the Global Burden of Disease Study 2013. Lancet. 2014;384(9945):766-81.. According to the World Health Organization (WHO), obesity is “a condition in which percentage body fat (PBF) is increased to an extent in which health and well-being are impaired”, and, due to the alarming prevalence increase, it was declared as a “global epidemic”2727 Obesity: preventing and managing the global epidemic. Report of a WHO consultation. World Health Organ Tech Rep Ser. 2000;894:i-253. PMID: 11234459.

In 2016, 1.3 billion adults were overweight worldwide and the number of adults with obesity increased by sixfold from 100 to 671 million (69–390 million women and 31–281 million men) between 1975 and 20162424 NCD Risk Factor Collaboration (NCD-RisC).

. One of the main challenges in addressing overweight and obesity lies in adopting a common public health measure of these conditions2828 Office of the Surgeon General (US); Office of Disease Prevention and Health Promotion (US); Centers for Disease Control and Prevention (US); National Institutes of Health (US). The surgeon general's call to action to prevent and decrease overweight and obesity. Rockville (MD): Office of the Surgeon General (US); 2001. PMID: 20669513. As a result, body mass index (BMI) is adopted as an indicator for defining overweight and obesity2323 Clinical guidelines on the identification, evaluation, and treatment of overweight and obesity in adults--the evidence report. National Institutes of Health. Obes Res. 1998;6(Suppl 2):51S-209. PMID: 9813653,3535 Wendler G, Nassif PAN, Malafaia O, Wendler E, Wendler IBT, Cirpiani LM.

In Ecuador, according to data published in the National Health and Nutrition Survey Ecuador (ENSANUT-ECU 2011–2013)2222 Equador. Ministerio de Salud Pública. Encuesta Nacional de Salud y Nutrición – ENSANUT, 2012-2013. 2018 Available at: https://www.salud.gob.ec/encuesta-nacional-de-salud-y-nutricion-ensanut/. Accessed: Out. 6, 2021.
https://www.salud.gob.ec/encuesta-nacion...
, the prevalence of overweight and obesity at a national level in people older than 19 years is approximately 62.8%, with rate being greater in women (65.5%) than in men (60%).

Currently, there are many treatments available for adults with overweight and obesity, including reduced calorie diet, exercises, behavior modification, and use of specific treatments; however, some of these approaches do not achieve very good results. The intragastric balloon (IGB) is a reversible, endoscopically placed device approved for limited-term use in overweight and obese patients. Since bariatric surgery is of high cost, with complication risks and invasiveness, the use of IGB treatment is a good alternative as it is safer and of lower costs. Some studies have shown moderate weight loss of 15 kg or more with the use of the IGB2121 Mui WL, Ng EK, Tsung BY, Lam CH, Yung MY.

This technique has been the most frequently used in practice and the most studied for this medical condition and may be performed in patients with mild obesity (BMI=30 kg/m2). Body weight loss achieved with intragastric balloon placement is associated with improvements in obesity-related metabolic illness1818 Kim SH, Chun HJ, Choi HS, Kim ES, Keum B, Jeen YT.

A meta-analysis showed that endoscopic obesity treatment could be effective and of substantial value if combined with a multidisciplinary and comprehensive treatment plan55 ASGE Bariatric Endoscopy Task Force and ASGE Technology Committee; Abu Dayyeh BK, Kumar N, Edmundowicz SA, Jonnalagadda S, Larsen M, et al.

.

The objective of this study was to contribute to the experience in the country in the evaluation of the use of IGB for achieving weight loss and its impact on body composition measurements.

METHODS

This is a retrospective, monocentric study, which included all patients who opted for the intragastric balloon Spatz® placement from January 2018 to July 2019, with fulfillment of inclusion and exclusion criteria.

The inclusion criteria for this study were as follows: patients who opted for the Spatz® intragastric balloon whose clinical history contained complete data for 12 months in the period between January 2018 and July 2019. A total of 121 patients were selected. Patients who do not complete 12 months of treatments were excluded.

The patients were analyzed after 6 and 12 months of the IGB placement, based on the parameters such as body weight (kg), BMI (kg/m2), musculoskeletal mass, percentage fat mass (%), fat-free mass (kg), basal metabolic rate (kcal), visceral fat area (cm2). and phase angle (°).

Statistical analysis

Qualitative variables are presented as proportions and percentages and continuous variables as mean and standard deviation. The normal distribution of continuous variables was explored using the Shapiro-Wilk test and found that most of them were non-normally distributed.

For body composition variables, statistical differences between gender were calculated with Mann-Whitney U test. Changes of body composition variables were calculated by each variable at last visit (12 months) minus variables at baseline. Comparisons among means of continuous variables were made using Friedman test and non-parametric alternative to the one-way ANOVA with repeated measures when data are non-normal. Post-hoc Dunn's test was performed. The significance was set at 0.05 (p<0.05). Mann-Whitney U test was used to compare the means of 2 independent samples, and the Wilcoxon test to compare the means of paired samples. Paired t-tests were used to compare mean of angle phase at 6 and 12 months. The relationship between body composition indexes and gender was analyzed using Pearson's chi-square test. Spearman's correlation coefficient was used to determine the correlations between variations in weight and body composition parameters. The data were analyzed by SPSS (version 24.0; SPSS Inc., Chicago, Illinois, USA).

Ethical aspects

The participants were informed about the purpose of the procedure. They first read over and sign a consent form informing them of their rights and the benefits and risks associated with the placement of intragastric balloon. All procedures performed were in accordance with the ethical standards of the institutional and with Helsinki Declaration. This report followed STROBE guidelines for observational studies. The study was approved by Ethics Committee SOM-2017-003.

RESULTS

A total number of 121 patients were selected for analysis, with 83 (68.6%) females and 38 (31.4%) males. Patients had a mean age of 36 years and height of 1.6 m±1 cm. Weight mean and standard deviation was 89.8±14.6 kg, and the BMI was 33.0±4.0 at pretreatment. At the end of the treatment, the BMI decreased to 29.4 kg/m2 with a mean weight of 79.8 kg. Compared to baseline values, the patients experienced significant reductions in weight, BMI, fat-free mass (FFM) (kg), basal metabolic rate (BMR) (kcal), visceral fat area (VFA), and phase angle (p<0.00) (Table 1).

The post-hoc comparison with Dunn's test showed a significant mean difference in indicators, before the IGB placement and after 6 and 12 months. In addition, a non-significant statistical difference is found between 6 and 12 months (Table 2).

Table 2
Post-hoc analysis of mean differences.

Average weight loss in the male group was 14.7±20.7 kg, which was higher than that in the female group. After 6–12 months of follow-up, our patients showed a mean BMI of 3.4 kg in men and 3.1 kg in women, but we could not demonstrate a significant difference between gender. A statistically significant difference was observed only in BW, MME, FFM, and phase angle. Values in men were higher (Table 3).

Table 3
Mean differences according to sex of patients at 12 months of balloon placement.

The mean percentage of total weight loss (TWL) achieved was 9.24±5.71 at 6 months and 9.37±6.51 at 12 months (non-significant difference: p=0.73, p>0.05). The mean percentage of excess weight loss (EWL) was 46.19±38.51 at 6 months and 45.28±38.43 at 12 months (p=0.72, p>0.05). We did not find any statistical differences between gender in these indicators in any of the two times (Table 4).

Table 4
Means of percentage of total weight loss and percentage of excess weight loss according to gender, at 6 and 12 months follow-up.

Regarding weight loss results, a generally accepted criterion to know if the method is successful is if percentage of TWL is >7% and percentage of EWL is >30%. According to this criterion, we compared percentage of EWL at two times. The proportions of patients having successful weight loss (TWL>7%) were 64.0% (n=78) at 6 months and 62.0% (75) at 12 months. The proportions of patients having successful weight loss (EWL>30%) were 62 and 62.8% at 6 and 12 months, respectively. There was a statistically significant difference in both cases. A statistically meaningful linear correlation between a 6-month EWL and TWL and a 12-month EWL or TWL was found (Table 5).

DISCUSSION

This is the first study to document outcomes with the use of IGB therapy in Ecuador. In the current study, 6 months of treatment with IGB was associated with improvements in the indicators measured. At the end of 12 months term, significant reductions were seen in both weight and BMI for most of the cohort. Some studies have reported on the efficacy of IGB in inducing significant weight loss over the short to medium period1616 Genco A, Cipriano M, Bacci V, Cuzzolaro M, Materia A, Raparelli L, et al.

also reported that preoperative intragastric balloon therapy may produce a favorable reduction of the visceral fat area and that the use of IGB for a few weeks may serve as a useful preparation procedure prior to laparoscopic bariatric surgery. We found that initial value of VFA decreased along the period of study.

Our results show a significant decrease in percentage of fat mass and free fat mass, while Donadio et al.1111 Donadio F, Sburlati LF, Masserini B, Lunati EM, Lattuada E, Zappa MA, et al.

found a reduction in percentage of fat mass (-19.5%), but not in fat-free mass.

Regarding FFM, our study demonstrated that men had a reduction of 7% and women 5%, without statistical differences between them. In a study performed in Poland, there was a 5.4% reduction in FFM1515 Gaździńska AP, Mojkowska A, Zieliński P, Gazdzinski SP.

These results were better observed in our patients between pretreatment and 6 months, where the reduction of these indicators was higher. Their means were not different between 6 and 12 months.

The overall TWL and EWL were 9.37±6.51% and 45.28±38.43% at 12 months, respectively. In the current study, approximately 60% of the individuals had very good results at 6 and at 12 months in both indicators, taking into account the criteria of Abu et al.11 Abu Dayyeh BK, Edmundowicz S, Thompson CC.

CONCLUSION

The study demonstrated a benefit of intragastric fluid-filled balloon on weight loss after 12 months. At the end of treatment, BMI and the measurements of body composition were significantly lower. Men benefited more than women from the treatment.

  • Financial source: None
  • Editorial Support: National Council for Scientific and Technological Development (CNPq).
  • Central Message The intragastric balloon is a reversible, endoscopically placed device approved for limited-term use in overweight and obese patients. The use of intragastric balloon treatment is a good alternative, as it is safer and has lower costs, and may be indicated in patients with mild obesity (BMI=30 kg/m2). Some studies have shown moderate weight loss of 15 kg or more with the use of the intragastric balloon.
  • Perspectives The study demonstrated a benefit of intragastric fluid-filled balloon on weight loss after 12 months. At the end of treatment, body mass index and the measurements of body composition were significantly lower. Men benefited more than women from the treatment.
