RESUMO

INTRODUCTION: Argon plasma coagulation (APC) alone is effective and safe at treating weight regain following Roux-en-Y gastric bypass (RYGB). However, technical details of the treatment vary widely among studies. Therefore, we aimed to create good clinical practice guidelines through a modified Delphi consensus, including experts from the collaborative Bariatric Endoscopy Brazilian group. METHODS: Forty-one locally renowned experts were invited to the consensus by email. Experiences of > 150 APC-treated cases or authorship of relevant articles were the eligibility criteria. An initial questionnaire with short-answer questions was distributed to the experts. The organizing committee converted the responses into statements for an online 2-day voting webinar. Consensus was defined as more than 67% of positive answers. Three consecutive voting rounds were planned with discussion and statement refinements between rounds. RESULTS: Thirty-seven experts fulfilled eligibility criteria and attended the live webinar voting. The total number of patients treated by the panel was 12,349. By the third round, all 79 statements reached consensus. The recommendations include the definition of dilated gastrojejunal anastomosis as ≥ 15 mm, minimum regain of 20% of the lost weight to indicate the APC therapy, 6 to 8 weeks as the ideal interval between ablation sessions, and stopping treatment when the stoma reaches < 12 mm of breadth. CONCLUSIONS: This consensus provides several recommendations based on a highly experienced panel of endoscopists. Although it covers most aspects of the treatment, the level of evidence is low for the majority of the statements. Therefore, bariatric endoscopists should be constantly attentive to new evidence on APC treatment.

RESUMO

PURPOSE: Bariatric endoscopy is a less invasive approach for obesity management, with better efficacy than pharmacological treatment and low morbidity. Endoscopic sleeve gastroplasty (ESG) is the remodeling of the stomach using a suturing device showing technical feasibility, safety, and sustained weight loss. With growing numbers of procedures worldwide, there is a need to standardize the procedure. MATERIALS AND METHODS: A consensus meeting was held in São Caetano do Sul-SP, Brazil, in June 2019, bringing together 47 Brazilian endoscopists with experience in ESG from all regions of the country. Topics on indications and contraindications of the procedure, pre-procedure evaluation and multidisciplinary follow-up, technique and post-procedure follow-up, and training requirements were discussed. An electronic voting was carried, and a consensus was defined as ≥ 70% agreement. RESULTS: The panel's experience consisted of 1828 procedures, with a mean percentage total body weight loss (TBWL) of 18.2% in 1 year. Adverse events happened in 0.8% of the cases, the most common being hematemesis. The selected experts discussed and reached a consensus on several questions concerning patient selection, contraindications for the procedure, technical details such as patient preparation, procedure technique, and patient follow-up. CONCLUSIONS: This consensus establishes practical guidelines for performance of ESG. The experience of 1828 procedures shows the expertise of the selected specialists participating in this consensus statement. The group's experience has a satisfactory weight loss with low adverse events rate. The main points discussed in this paper may serve as a guide for endoscopists performing ESG. Practical recommendations and technique standardization are described.

RESUMO

BACKGROUND: Endoscopic sleeve gastroplasty (ESG) is an option for patients with Class I and II obesity or patients who refuse to undergo a laparoscopic bariatric surgery. The aims of this study are as follows: (1) to demonstrate a short-term outcome after primary ESG and (2) to compare the effectiveness of weight loss between Class I and Class II obesity patients. METHODS: Patients undergoing ESG at four bariatric centers in Brazil between April 1, 2017 and December 31, 2018 were prospectively enrolled in the study (BMI 30.0-39.9 kg/m2). ESG was performed using Overstitch (Apollo Endosurgery, Austin, TX). Descriptive analysis, t test, Chi-square test, and Mann-Whitney test were used to present the results. RESULTS: A total of 233 patients underwent primary ESG. The mean age and BMI of the patients were 41.1 years and 34.7 kg/m2, respectively. Following ESG, the mean percentage of total weight loss (TWL) was 17.1% at 6 months and 19.7% at 12 months. Percentage of excess BMI loss (EBMIL) was 47.3% at 6 months and 54.8% at 12 months after ESG. The mean EBMIL was significantly greater among patients with Class I obesity than those with Class II obesity at 6 (51.1% vs. 43.7%) and 12 months (60.2% vs. 49.2%). One patient experienced bleeding during the procedure that was managed with sclerotherapy. CONCLUSION: Short-term results suggest that ESG is a safe and effective option for patients with Class I and II obesity.
