Abstract
BACKGROUND Our aim was to determine the efficacy and safety of intragastric balloon (IGB) application and the factors affecting its success by evaluating the results of patients who underwent IGB. MATERIALS AND METHODS A total of 277 consecutive patients that underwent IGB between January 2019-September 2020 in our clinic were evaluated. Patients' demographic data, height and weight before the IGB procedure, weight at 6 and 12 months after the procedure, follow-up period, complication status, and whether they received dietician's assistance during the follow-up were recorded. RESULTS In 5 (1.8%) patients, IGB was removed for various reasons before the standard period of 6 months. The mean age of the patients was 35.6±9.5 years, the mean baseline weight and body mass index (BMI) was 92.6±14 kg and 33.5±5.4 kg/m 2 respectively. The mean follow-up time was 13±4.9 months, whereas in 146(53.6%) patients the follow-up was≥12 months. In the 6-month follow-up, the mean %excess weight loss and %body weight loss were 65.65±25.19% and 14.69±6.96%, respectively, whereas at the 12-month follow-up they were 32.38±24.79% and 6.56±5.31%, respectively. High BMI (odds ratio=1.2, 95% CI=1.0-1.2) and not receiving dietitian's assistance (odds ratio=8.5, 95% CI=3.1-23.7) were independent risk factors for unsuccessful IGB application at both 6-month and 12-month follow-ups. CONCLUSION IGB application is a relatively effective and safe weight loss treatment for overweight and obese individuals. High BMI and not getting help from a dietician are risk factors for failure of IGB. To increase compliance with dieticians and therefore success of IGB application, patients should undergo psychiatric evaluation before IGB procedure, and receive psychiatric support, if necessary.

Fluid-filled intragastric balloons are an effective and safe weight loss option across BMI and age ranges. Surg Endosc 2021; 36:5160-5166. [PMID: 34845556 DOI: 10.1007/s00464-021-08892-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2021] [Accepted: 11/16/2021] [Indexed: 02/07/2023]
Abstract
INTRODUCTION Obesity is an expanding public health problem, resulting in more than half a billion adults worldwide. Intragastric balloon (IGB) placement is a weight loss alternative for obese patients with an inadequate weight loss response to diet and exercise. The aim of this study is to examine the efficacy and safety of the single-chamber fluid-filled IGB for weight loss and compare its results across different age groups. METHODS We performed a database review of 239 consecutive patients from two outpatient GI clinics who underwent placement of an IGB. Our final analysis composed of 239 IGB placements in 232 patients (mean age, 44.5 ± 10.3 years; 67% female; baseline BMI 42.0 ± 9.0). Efficacy outcomes included the percentage of the total (%TWL) and excess weight loss (%EWL). Safety outcomes were measured as the number of patients who required early IGB removal (before 6 months). RESULTS %TWL at 3 months was 10.1% and 14.4% at 6 months. Overall, 92%, 74%, and 47% of patients lost 5%, 10%, and 15% of total weight at 6 months, respectively. %EWL was 22.1% and 30.7% at 3 and 6 months post-IGB placement, respectively. The balloon was safely removed at six months after placement in most patients, whereas in 13.0% of cases early removal was performed at an average of 12.0 weeks after placement (range, 2 days-23 weeks). CONCLUSION The use of a single-chamber fluid-filled IGB is successful in inducing a significant amount of weight loss in almost three-fourths of patients six months after its placement. This beneficial effect is seen across different BMI ranges and age groups at a similar level. IGBs should be considered an effective and safe alternative for obese patients who fail lifestyle interventions and conservative measures, fulfilling the unmet needs of many who are unwilling or unable to undergo bariatric surgery.

How much abdominal fat do obese patients lose short term after laparoscopic sleeve gastrectomy? A quantitative study evaluated with MRI. Quant Imaging Med Surg 2021; 11:4569-4582. [PMID: 34737924 DOI: 10.21037/qims-20-1380] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2020] [Accepted: 05/28/2021] [Indexed: 11/06/2022]
Abstract
Background This study aimed to elucidate the changes in the amount of abdominal adipose tissue after laparoscopic sleeve gastrectomy in obese Chinese patients over a relatively short follow-up period and to analyze the differences in the effects of surgery between genders. Methods Ninety-one patients were enrolled in the study, including 18 males and 73 females. These patients underwent laparoscopic sleeve gastrectomy between November 2017 and November 2019. Before and short term after surgery, the areas of subcutaneous/visceral adipose tissue and the liver proton density fat fraction were calculated with upper abdominal magnetic resonance (MR) examinations. Results Approximately 100 days after surgery, the median values of weight loss and body mass index reduction were 23.1 kg and 8.1 kg/m2, respectively. The patients achieved a greater absolute loss of subcutaneous adipose tissue index than of visceral adipose tissue index (3.2×10-3 vs. 1.6×10-3, P<0.001). The amount of weight loss, body mass index loss and absolute/relative reduction in visceral adipose tissue index were much greater in males than in females (31.7 vs. 21.7 kg, P<0.001; 9.8 vs. 7.9 kg/m2, P=0.016; 2.5×10-3 vs. 1.3×10-3, P=0.007; 28.2% vs. 20.9%, P=0.029). There was a correlation between decreased amounts in subcutaneous and visceral adipose tissue in sum and weight loss (r=0.282, P=0.032). The absolute/relative reduction in visceral adipose tissue index was also correlated with absolute/relative reduction in liver proton density fat fraction (r=0.283, P=0.013; r=0.372, P=0.001). Conclusions The reductions in body weight and visceral fat were more significant in male patients. The sum of absolute reduction in subcutaneous and visceral fat deposits was correlated with weight loss, in all patients enrolled. For severely obese patients, an upper abdominal MR examination could assess the body tissue composition and how it changes after bariatric surgery.

Development and validation of a scoring system for pre-surgical and early post-surgical prediction of bariatric surgery unsuccess at 2 years. Sci Rep 2021; 11:21067. [PMID: 34702864 PMCID: PMC8548411 DOI: 10.1038/s41598-021-00475-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Accepted: 10/11/2021] [Indexed: 12/13/2022] Open
Abstract
Bariatric surgery (BS) is an effective treatment for morbid obesity. However, a simple and easy-to-use tool for the prediction of BS unsuccess is still lacking. Baseline and follow-up data from 300 consecutive patients who underwent BS were retrospectively collected. Supervised regression and machine-learning techniques were used for model development, in which BS unsuccess at 2 years was defined as a percentage of excess-weight-loss (%EWL) < 50%. Model performances were also assessed considering the percentage of total-weight-loss (%TWL) as the reference parameter. Two scoring systems (NAG-score and ENAG-score) were developed. NAG-score, comprising only pre-surgical data, was structured on a 4.5-point-scale (2 points for neck circumference ≥ 44 cm, 1.5 for age ≥ 50 years, and 1 for fasting glucose ≥ 118 mg/dL). ENAG-score, including also early post-operative data, was structured on a 7-point-scale (3 points for %EWL at 6 months ≤ 45%, 1.5 for neck circumference ≥ 44 cm, 1 for age ≥ 50 years, and 1.5 for fasting glucose ≥ 118 mg/dL). A 3-class-clustering was proposed for clinical application. In conclusion, our study proposed two scoring systems for pre-surgical and early post-surgical prediction of 2-year BS weight-loss, which may be useful to guide the pre-operative assessment, the appropriate balance of patients' expectations, and the post-operative care.

Abstract
BACKGROUND AND AIMS Nonalcoholic fatty liver disease, now renamed metabolic dysfunction-associated fatty liver disease (MAFLD), is common in obese patients. Intragastric balloon (IGB), an obesity management tool with low complication risk, might be used in MAFLD treatment but there is still unexplained heterogeneity in results across studies. METHODS We conducted a systematic search of 152 citations published up to September 2020. Meta-analyses, stratified analyses, and meta-regression were performed to evaluate the efficacy of IGB on homeostasis model assessment of insulin resistance (HOMA-IR), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and gamma-glutamyl transpeptidase (GGT), and to identify patients most appropriate for IGB therapy. RESULTS Thirteen observational studies and one randomized controlled trial met the inclusion criteria (624 participants in total). In the overall estimate, IGB therapy significantly improved the serum markers change from baseline to follow-up [HOMA-IR: 1.56, 95% confidence interval (CI)=1.16-1.95; ALT: 11.53 U/L, 95% CI=7.10-15.96; AST: 6.79 U/L, 95% CI=1.69-11.90; GGT: 10.54 U/L, 95% CI=6.32-14.75]. In the stratified analysis, there were trends among participants with advanced age having less change in HOMA-IR (1.07 vs. 1.82). The improvement of insulin resistance and liver biochemistries with swallowable IGB therapy was no worse than that with endoscopic IGB. Multivariate meta-regression analyses showed that greater HOMA-IR loss was predicted by younger age (p=0.0107). Furthermore, effectiveness on ALT and GGT was predicted by basal ALT (p=0.0004) and GGT (p=0.0026), respectively. CONCLUSIONS IGB is effective among the serum markers of MAFLD. Younger patients had a greater decrease of HOMA-IR after IGB therapy.

Abstract
PURPOSE Bariatric surgery (BS) has been recognized as an effective treatment for most patients with morbid obesity, but a variable range of patients failed to achieve a successful weight-loss. Controversial data are available about predictors of unsuccess. We aimed to retrospectively assess whether clinical baseline characteristics of patients submitted to sleeve gastrectomy (SL) or gastric bypass (GBP) were associated with unsuccessful weight-loss after 12 and 24-month follow-up. METHODS Three hundred patients who underwent BS from the 1st January 2016, with at least 24-months follow-up, were enrolled. Patients were divided according to their percentage of excess weight-loss (%EWL) either < 50% or ≥ 50% after 12 and 24-month follow-up. RESULTS None of the patients was lost at follow-up; 56 (18.7%) patients showed a %EWL < 50% at 24 months. Age, neck circumference, obstructive sleep apnea (OSA) were significantly higher, while total cholesterol and %EWL 6-months lower in those with %EWL < 50% at 12-months. Age, neck circumference, male and OSA rates were increased, while %EWL at 6-months lower in patients with %EWL < 50% at 24-months. In a multiple regression model, age (OR = 1.076; 95% CI 1.029-1.125; p = 0.001; OR = 1.066; 1.027-1.107; p < 0.001) and %EWL at 6-months (OR = 0.876; 0.840-0.913; p < 0.001; OR = 0.950; 0.928-0.972; p < 0.001) were associated with %EWL < 50% both at 12- and 24-months, respectively, and neck circumference (OR = 1.142; 1.011-1.289; p = 0.032) with %EWL < 50% at 24-months. CONCLUSION Older age, larger neck circumference, and %EWL at 6-months were significantly associated with BS unsuccess, showing almost 90% of those patients an unsuccessful weight-loss early after surgery. Further larger studies with longer follow-up are needed to confirm these results.

Predictors of weight loss in participants with obesity following bariatric surgery - A prospective longitudinal fMRI study. Appetite 2021; 163:105237.

Abstract
Prevalence rates of overweight and obesity are increasing worldwide and are amongst the leading causes of death. Participants with obesity also suffer from poorer mental health with a concomitant reduced quality of life. Bariatric surgery outperforms other existing weight optimization approaches. However, hitherto, it was not possible to identify factors predicting weight loss following surgery. Therefore, we aimed at investigating neural and behavioral predictors of weight loss, as well as the neurological underpinnings of food cue-induced craving before and after bariatric surgery. The total sample consisted of 26 participants with obesity (17 females and 9 males, mean age 41 ± 12 years, mean BMI 46 ± 6 kg/m2, 21 received Roux-en-Y gastric bypass and 5 sleeve gastrectomy). Participants with obesity were prospectively assessed using functional magnetic resonance imaging two weeks before, as well as eight and 24 weeks after surgery. Imaging data were available for 11 individuals; 10 received Roux-en-Y gastric bypass and one sleeve gastrectomy. Subjective cue-induced food craving correlated positively with brain activation in the amygdala, the parahippocampal gyrus, and hippocampus, and negatively with brain activation in frontal brain regions. In the total sample (N = 26), perceived feeling of hunger and YFAS sum score explained 50.6% of the variance (R2 = 0.506, F(1,23) = 10.759, p < 0.001) and in the imaging sample, cue-induced food craving at baseline before surgery explained 49.6% of the variance (R2 = 0.496, F(1,23) = 7.862, p = 0.023) of % total weight loss (%TWL). In other words, with respect to %TWL, bariatric surgery was most efficient in candidates characterized by high cue-induced food craving, high-perceived feeling of hunger and a low YFAS sum score.
