Endoscopic Sleeve Gastroplasty in Those With a Body Mass Index of 27-30.

INTRODUCTION: Endoscopic sleeve gastroplasty (ESG) is safe and effective in patients with a body mass index (BMI) more than 30, with few cases reported in patients with overweight (BMI 27-30). However, evidence is lacking in the overweight group because the procedure is not currently performed routinely for such patients. In this study, we aim to evaluate the safety and efficacy of ESG in patients with a BMI between 27 and 30 who failed other weight loss modalities and/or had weight-related comorbidities. METHODS: This was a subgroup analysis of data pertaining to adults with a BMI between 27 and 30 who underwent ESG as a primary weight loss intervention. Data were abstracted from our longitudinal, prospective single-center registry. We analyzed weight loss, comorbidity resolution, adverse events, revisions, and quality of life using the Bariatric Analysis and Reporting Outcome System. RESULTS: Of 3,797 ESG procedures, 656 patients (17%) had a BMI of 27-30. The mean age was 33 ± 9 years and women comprised 94% (n = 616) of the sample. The mean % total weight loss at 6, 12, 24, and 36 months after ESG was 11.0 ± 7.2, 15.5 ± 6.3, 15.1 ± 8.3%, and 13.3 ± 9.9%, respectively. Eight of 22 patients with diabetes (36%) and 9 of 51 patients (18%) with hypertension experienced complete remission. Two patients were hospitalized with bleeding. Twenty-three patients (3.5%) underwent revision to laparoscopic sleeve gastrectomy or repeat ESG. Six more patients underwent suture removal. A total of 214 of 261 patients (82%) rated quality of life after ESG as good or better. DISCUSSION: ESG seems to be well tolerated, safe, and effective in patients with a BMI of 27-30.

Long-term outcomes of laparoscopic sleeve gastrectomy in those with class I obesity: safety, efficacy, and quality of life.

BACKGROUND: Class I obesity carries significant morbidity and mortality risk similar to higher grades of obesity, and persons with class I obesity have a high risk of progression to class II and III obesity. While bariatric surgery has made strides in safety and efficacy, it remains inaccessible for persons with class I obesity (body mass index [BMI] of 30-35 kg/m2). OBJECTIVES: To assess safety, weight loss durability, co-morbidity resolution, and quality of life after laparoscopic sleeve gastrectomy (LSG) in persons with class I obesity. SETTING: Multidisciplinary medical center that specializes in obesity management. METHODS: A longitudinal prospective single-surgeon registry was queried for data pertaining to persons with class I obesity who underwent primary LSG. Primary endpoint was weight loss. Secondary endpoints included change in obesity-related co-morbidities, adverse events, and post hoc analysis of symptoms of gastroesophageal reflux disease (GERD) and Bariatric Analysis and Reporting Outcome System results. Follow-up was divided into short- (1-3 yr), intermediate- (4-7 yr), and long-term (8-12 yr). We evaluated percent excess weight loss (%EWL) using linear mixed models adjusting for age, sex, years since operation, and baseline BMI. Least-squares means estimates and 95% confidence intervals (CI) were generated. RESULTS: Of 13,863 bariatric procedures, a total of 1851 patients were included. Mean baseline BMI, age, and male:female ratio were 32.6 ± 2.1 kg/m2, 33.7 ± 9.2 years, and 1:5, respectively. Adjusted mean %EWL (95% CI) at short-, intermediate-, and long-term follow-up were 111% (95% CI, 91%-131%), 110% (95% CI, 89%-131%), and 141% (95% CI, 57%-225%), respectively. Of 195 patients with type 2 diabetes, 59% experienced complete remission, and of 168 patients with hypertension, 43% experienced complete remission. Being on oral antidiabetes medication was a significant predictor of sustained remission compared with being on insulin or combination therapy (P < .001). Sixty-nine patients had symptoms of GERD before surgery, which improved in 55 (79.7%). Thirty-three patients developed de novo symptoms of GERD. The average Bariatric Analysis and Reporting Outcome System score was 4.5 ± 1.7, with 83% of participants rating their quality of life after surgery as good, very good, or excellent. CONCLUSION: Those with class I obesity who undergo LSG experience normalization of weight, sustained remission of co-morbidity, and good quality of life without significant risk of morbidity or mortality.

Endoscopic gastroplasty versus laparoscopic sleeve gastrectomy: a noninferiority propensity score-matched comparative study.

BACKGROUND AND AIMS: Endoscopic bariatric therapies are less-invasive alternatives to bariatric surgery, and endoscopic gastroplasty (ESG) represents the latest evolution. This study aims to compare weight loss, safety, and comorbidity resolution of ESG compared with laparoscopic sleeve gastrectomy (LSG). METHODS: This was a propensity score-matched study of patients who underwent ESG or LSG. Primary outcome was weight loss at 6, 12, 24, and 36 months. A noninferiority margin of 10% total weight loss (%TWL) was used. Secondary outcomes were safety and comorbidity resolution. RESULTS: A 1:1 propensity score match yielded 3018 patient pairs. Average age and body mass index (BMI) were 34 ± 10 years and 33 ± 3 kg/m2, respectively, and 89% were women. Mean percentage of excess weight loss at 1, 2, and 3 years after ESG was 77.1% ± 24.6%, 75.2% ± 47.9%, and 59.7% ± 57.1%, respectively. Mean percentage of excess weight loss at 1, 2, and 3 years after LSG was 95.1% ± 20.5%, 93.6% ± 31.3%, and 74.3% ± 35.2%, respectively. The mean difference in %TWL was 9.7% (95% confidence interval [CI], 6.9-11.8; P < .001), 6.0% (95% CI, -2.0 to 9.4; P < .001), and 4.8% (95% CI, -1.5 to 8.7; P < .001) at 1, 2, and 3 years, respectively. Noninferiority was demonstrated at all follow-up visits. Fourteen ESG patients developed adverse events (.5%) versus 10 LSG patients (.3%). Comorbidity remission rates after ESG versus LSG were 64% versus 82% for diabetes, 66% versus 64% for dyslipidemia, and 51% versus 46% for hypertension, respectively. Eighty ESG patients (2.7%) underwent revision to LSG for insufficient weight loss or weight regain, and 28 had resuturing after primary ESG (.9%). CONCLUSIONS: ESG induces noninferior weight loss to LSG with similar comorbidity resolution and safety profiles.
