RESUMEN
Non-alcoholic fatty liver disease (NAFLD) is the most common cause of liver disease worldwide. Endoscopic sleeve gastroplasty (ESG) has proven to be feasible, safe, and effective in the management of obesity. We performed the first systematic review and meta-analysis evaluating NAFLD and other metabolic parameters 12 months post-ESG. Four observational studies with a total of 175 patients were included. The results showed a significant (p < 0.05) reduction of 4.85 in hepatic steatosis index (95% CI - 6.02, - 3.67), 0.5 in NAFLD fibrosis score (95% CI - 0.80, - 0.19), 6.32 U/l in ALT (95% CI - 9.52, - 3.11), 17.28% in TWL (95% CI - 18.24, - 16.31), 6.31 kg/m2 in BMI (95% CI - 8.11, - 4.52), 47.97% in EWL (95% CI - 49.10, - 46.84), and 0.51% in HbA1c (95% CI - 0.90, - 0.12). ESG improves liver parameters, provides weight loss, and reduces HbA1c levels in patients suffering from NAFLD.

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.

ABSTRACT Background: Bariatric surgery is currently the most effective method to ameliorate co-morbidities as consequence of morbidly obese patients with BMI over 35 kg/m2. Endoscopic techniques have been developed to treat patients with mild obesity and ameliorate comorbidities, but endoscopic skills are needed, beside the costs of the devices. Aim: To report a new technique for internal gastric plication using an intragastric single port device in an experimental swine model. Methods: Twenty experiments using fresh pig cadaver stomachs in a laparoscopic trainer were performed. The procedure was performed as follow in ten pigs: 1) volume measure; 2) insufflation of the stomach with CO2; 3) extroversion of the stomach through the simulator and installation of the single port device (Gelpoint Applied Mini) through a gastrotomy close to the pylorus; 4) performance of four intragastric handsewn 4-point sutures with Prolene 2-0, from the gastric fundus to the antrum; 5) after the performance, the residual volume was measured. Sleeve gastrectomy was also performed in further ten pigs and pre- and post-procedure gastric volume were measured. Results: The internal gastric plication technique was performed successfully in the ten swine experiments. The mean procedure time was 27±4 min. It produced a reduction of gastric volume of a mean of 51%, and sleeve gastrectomy, a mean of 90% in this swine model. Conclusion: The internal gastric plication technique using an intragastric single port device required few skills to perform, had low operative time and achieved good reduction (51%) of gastric volume in an in vitro experimental model.
RESUMO Racional: A cirurgia bariátrica é atualmente o método mais efetivo para melhorar as co-morbidades decorrentes da obesidade mórbida com IMC acima de 35 kg/m2. Técnicas endoscópicas foram desenvolvidas para tratar pacientes com obesidade leve e melhorar as comorbidades, mas habilidades endoscópicas são necessárias, além dos custos. Objetivo: Relatar uma nova técnica para a plicatura gástrica interna utilizando um dispositivo intragástrico de portal único em modelo experimental de suínos. Métodos: Foram realizados 20 experimentos utilizando estômagos de cadáver de porco fresco em um instrutor laparoscópico. O procedimento foi realizado da seguinte forma em dez porcos: 1) medida de volume; 2) insuflação do estômago com CO2; 3) extroversão do estômago através do simulador e instalação do dispositivo de uma única via (Gelpoint Applied Mini) através de uma gastrotomia próxima ao piloro; 4) realização de quatro suturas de quatro pontos intra-gástricas com Prolene 2-0, desde o fundo gástrico até o antro; 5) medição do volume residual. A gastrectomia vertical foi também realizada em mais dez suínos e o volume gástrico pré e pós-procedimento foi medido. Resultados: A técnica de plicatura gástrica interna foi realizada com sucesso nos dez experimentos com suínos. O tempo médio do procedimento foi de 27±4 min. Produziu redução do volume gástrico em média de 51%, e a gastrectomia vertical em média de 90% neste modelo suíno. Conclusão: A técnica de plicatura gástrica interna, utilizando um dispositivo intragástrico de uma única via, exigiu poucas habilidades para ser realizada, teve baixo tempo operatório e obteve boa redução (51%) do volume gástrico em um modelo experimental in vitro.

BACKGROUND: Attempts are being made in recent years to replace open surgery with endoscopic techniques in some obese patients when medical treatment fails, as they are considered to be less-invasive procedures. To date, there is little scientific evidence regarding their effectiveness. CLINICAL CASES: The cases are reported of 2 patients who attended our surgery looking for an effective bariatric surgical treatment after failed endoscopic sleeve gastroplasty. CONCLUSIONS: Laparoscopic sleeve gastrectomy after failure of an endoscopic technique does not offer great variation from the standard technique.

ABSTRACT Background: Less invasive and complex procedures have been developed to treat obesity. The successful use of Endoscopic Sleeve Gastroplasty using OverStitch(r) (Apollo Endosurgery, Austin, Texas, USA) has been reported in the literature. Aim: Present technical details of the procedure and its surgical/ endoscopic preliminary outcome. Method: The device was used to perform plications along the greater curvature of the stomach, creating a tubulization similar to a sleeve gastrectomy. Result: A male patient with a BMI of 35.17 kg/m2 underwent the procedure, with successful achievement of four plications, and preservation of gastric fundus. The procedure was successfully performed in 50 minutes, time without bleeding or other complications. The patient presented mild abdominal pain and good acceptance of liquid diet. Conclusions: The endoscopic gastroplasty procedure was safe, with acceptable technical viability, short in duration and without early complications.
RESUMO Racional: Procedimentos menos invasivos e complexos têm sido desenvolvidos para o tratamento da obesidade. A gastroplastia vertical endoscópica com uso de OverStitch(r) (Apollo Endosurgery, Austin, TX, EUA) já foi relatada com sucesso na literatura. Objetivo: Apresentar detalhes técnicos do procedimento e seu resultado cirúrgico/endoscópico preliminar. Método: O equipamento foi utilizado para realizar plicaturas ao longo da grande curvatura gástrica, objetivando tubulização do estômago semelhante a gastrectomia vertical. Resultado: O método foi aplicado em paciente com IMC 35,17 kg/m2, sendo realizadas quatro plicaturas, preservando o fundo gástrico. O procedimento foi realizado com sucesso em 50 min, sem sangramento ou outras complicações. O paciente evoluiu com dor abdominal leve, e teve boa aceitação de dieta líquida. Conclusão: A realização da gastroplastia endoscópica foi segura, com viabilidade técnica aceitável e reprodutível, com curto tempo de procedimento, sem complicações precoces.
