- Effectiveness of intragastric balloon for obesity: A systematic review and meta-analysis based on randomized control trials(2016) MOURA, Diogo; OLIVEIRA, Joel; MOURA, Eduardo G. H. De; BERNARDO, Wanderlei; GALVAO NETO, Manuel; CAMPOS, Josemberg; POPOV, Violeta B.; THOMPSON, CristopherBackground: Obesity has become a worldwide epidemic, and many methods are currently used to reduce obesity. This systematic review shows the effectiveness of the intragastric balloon (IGB) method compared to the sham/diet (s/d) method. Objective: To demonstrate the effectiveness of the IGB method compared to the s/d method. Setting: Hospital das Clinicas da Universidade de Sao Paulo, Brazil, Public Hospital. Methods: After searching MEDLINE, Embase, Cochrane, Lilacs, Scopus, and CINAHL, only enrolled randomized control trials comparing IGB/diet with s/d were analyzed. For qualitative analysis, 12 studies were selected, and 9 of these were acceptable for quantitative analysis. Results: The IGB/diet is more effective than s/d when comparing body mass index (BMI) loss with a mean difference of 1.1 kg/m(2) by the Student's t test and 1.41 kg/m(2) by the meta-analysis, with significant differences in both. It is also more effective in weight loss (WL), with a mean difference of 2 kg by the Student's t test and 3.55 kg by the meta-analysis. In the qualitative analysis of % excess WL (%EWL), the mean %EWL is 14.0% in favor of the IGB group compared to the s/d group by the Student's t test; however, no significant difference was found between these groups by quantitative analysis. Conclusion: Based on randomized control trial data alone, IGB >400 mL is more effective than sham/diet in achieving BMI loss, WL, and %EWL.

conferenceObject INTRALESIONAL STEROID INJECTION VERSUS ORAL PREDNISOLONE FOR THE PREVENTION OF ESOPHAGEAL STRICTUTE AFTER ENDOSCOPIC SUBMUCOSAL DISSECTION: A RANDOMIZED CLINICAL TRIAL(2023) OLIVEIRA, Joel; MARTINS, Bruno Da Costa; NOBRE, Renata; PAULO, Gustavo De; LENZ, Luciano; LIMA, Marcelo De; SAFATLE-RIBEIRO, Adriana; MALUF-FILHO, Fauze- Validation of classic and expanded criteria for endo-scopic submucosal dissection of early gastric cancer: 7 years of experience in a Western tertiary cancer center(2018) MENDONCA, Ernesto Quaresma; PESSORRUSSO, Fernanda Cristina Simoes; RAMOS, Marcus Fernando Kodama Pertille; JACOB, Carlos Eduardo; OLIVEIRA, Joel Fernandez de; RIBEIRO, Maria Sylvia; SAFATLE-RIBEIRO, Adriana; ZILBERSTEIN, Bruno; RIBEIRO JUNIOR, Ulysses; MALUF-FILHO, FauzeOBJECTIVE: Our aim was to evaluate the Japan Gastroenterological Endoscopy Society criteria for endoscopic submucosal resection of early gastric cancer (EGC) based on the experience in a Brazilian cancer center. METHODS: We included all patients who underwent endoscopic submucosal resection for gastric lesions between February 2009 and October 2016. Demographic data and information regarding the endoscopic resection, pathological report and follow-up were obtained. Statistical calculations were performed with Fisher's exact test and chi-square tests, with 95% confidence intervals. RESULTS: In total, 76% of the 51 lesions were adenocarcinomas, 16% were adenomas, and 8% had other diagnoses. The average size was 19.9 mm (+/- 11.7). The average procedure length was 113.9 minutes (+/- 71.4). The complication rate was 21.3%, with only one patient who needed surgical treatment (transmural perforation). Among the adenocarcinomas, 39.5% met the classic criteria for curability, 31.6% met the expanded criteria and 28.9% met the criteria for noncurative resection. Analysis of the indication criteria and curability revealed differences among cases with ""only-by-size"" expanded criteria (64.28%), other expanded criteria (40%) and classic criteria (89.47%), with a p-value of 0.049. During follow-up (15.8 months; +/- 14.3), 86.1% of the EGC patients had no recurrence. When well-differentiated and poorly differentiated lesions or lesions included in the classic and expanded criteria were compared, there were no differences in recurrence. The noncurative group presented a higher recurrence rate than the classic group (p=0.014). CONCLUSION: These results suggest that the Japanese endoscopic submucosal resection criteria might be useful for endoscopic treatment of EGC in Western countries.
