    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.

    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. de
    Fistula 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.

    Choledochoduodenostomy: Outcomes and limitations
    (2019) ARTIFON, Everson Luiz De Almeida; VISCONTI, Thiago A. C.; BRUNALDI, Vitor O.
    The EUS-guided biliary drainage (EUS-BD) has gained broad acceptance as the preferred approach after failed ERCP for malignant biliary obstruction. Despite the drainage route, namely, transhepatic or transduodenal, the technical and clinical success rates are high. Because of such good outcomes with tolerable adverse events (AEs) rate, the EUS-BD might soon even replace the ERCP for primary biliary decompression in patients at high risk of failed biliary cannulation. Among the EUS-BD techniques, the choledochoduodenostomy seems to carry the lower risk of AEs and should be considered the first-line EUS approach for biliary decompression.
