conferenceObject Extreme Endoscopic Treatment for Gastric Bypass Anastomosis Disconnection(2017) MOURA, Eduardo G. de; MINATA, Mauricio K.; SANTOS, Marcos E. dos; MOURA, Diogo T. de; CLEMENTE JUNIOR, Cesar C. de; MATUGUMA, Sergio E.; SANTO, Marco Aurelio- Suction versus slow-pull for endoscopic ultrasound-guided fine-needle aspiration of pancreatic tumors: a prospective randomized trial(2020) CHENG, Spencer; BRUNALDI, Vitor O.; MINATA, Mauricio K.; CHACON, Danielle A.; SILVEIRA, Eduardo B.; MOURA, Diogo T. H. de; SANTOS, Marcos E. L. Dos; MATUGUMA, Sergio E.; CHAVES, Dalton M.; FRANCA, Raony F.; JACOMO, Alfredo L.; ARTIFON, Everson L. A.Background: Suction (S) is commonly used to improve cell acquisition during endoscopic ultrasoundguided fine-needle aspiration (EUS-FNA). Slow-pull (SP) sampling is another technique that might procure good quality specimens with less bloodiness. We aimed to determine if SP improves the diagnostic yield of EUS-FNA of pancreatic masses. Methods: Patients with pancreatic solid masses were randomized to four needle passes with both techniques in an alternate fashion. Sensitivity, specificity, positive, and negative predictive values were calculated. Cellularity and bloodiness of cytological samples were assessed and compared according to the technique. Results: Sensitivity, specificity, and accuracy of suction vs. SP were 95.2% vs. 92.3%; 100% vs. 100; 95.7% vs. 93%, respectively. As to the association of methods, they were 95.6, 100 and 96%, respectively. Positive predictive values for S and SP were 100%. There was no difference in diagnostic yield between S and SP (p = 0.344). Cellularity of samples obtained with SP and Suction were equivalent in both smear evaluation (p = 0.119) and cell-block (0.980). Bloodiness of SP and suction techniques were similar as well. Conclusions: S and SP techniques provide equivalent sensitivity, specificity, and accuracy. Association of methods seems to improve diagnostic yield. Suction does not increase the bloodiness of samples compared to slow-pull.
conferenceObject Carbon Dioxide Insufflation Versus Air Insufflation in Enteroscopy: A Systematic Review(2017) AQUINO, Julio Cesar M.; MOURA, Eduardo G. de; BERNARDO, Wanderlei M.; MINATA, Mauricio K.; ROCHA, Rodrigo S.; MORITA, Flavio Hiroshi A.; IDE, Edson; KUGA, Rogerio; ISHIDA, Robson K.- Efficacy and Safety of Stents in the Treatment of Fistula After Bariatric Surgery: a Systematic Review and Meta-analysis(2018) OKAZAKI, Ossamu; BERNARDO, Wanderley M.; BRUNALDI, Vitor O.; CLEMENTE JUNIOR, Cesar C. de; MINATA, Mauricio K.; MOURA, Diogo T. H. de; SOUZA, Thiago F. de; CAMPOS, Josemberg Marins; SANTO, Marco Aurelio; MOURA, Eduardo G. H. deFistula development is a serious complication after bariatric surgery. We performed a systematic review and meta-analysis to assess the efficacy of fistula closure and complications associated with endoscopic stent treatment of fistulas, developed after bariatric surgeries, particularly Roux-en-Y gastric bypass (RYGB) and gastric sleeve (GS). Studies involving patients with fistula after RYGB or GS and those who received stent treatment only were selected. The analyzed outcomes were overall success rate of fistula closure, mean number of stents per patient, mean stent dwelling time, and procedure-associated complications. Current evidence from identified studies demonstrates that, in selected patients, endoscopic stent treatment of fistulas after GS or RYGB can be safe and effective.
