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.
- Pure Cut or Endocut for Biliary Sphincterotomy? A Multicenter Randomized Clinical Trial(2023) FUNARI, Mateus Pereira; BRUNALDI, Vitor Ottoboni; PROENCA, Igor Mendonca; GOMES, Pedro Victor Aniz; QUEIROZ, Lucas Tobias Almeida; VIEIRA, Yuri Zamban; MATUGUMA, Sergio Eiji; IDE, Edson; FRANZINI, Tomazo Antonio Prince; SANTOS, Marcos Eduardo Lera dos; CHENG, Spencer; MINATA, Mauricio Kazuyoshi; SANTOS, Jose Sebastio dos; MOURA, Diogo Turiani Hourneaux de; KEMP, Rafael; MOURA, Eduardo Guimares Hourneaux deINTRODUCTION: Adverse events (AE) after endoscopic retrograde cholangiopancreatography (ERCP) are not uncommon and post-ERCP acute pancreatitis (PEP) is the most important one. Thermal injury from biliary sphincterotomy may play an important role and trigger PEP or bleeding. Therefore, this study evaluated the outcomes of 2 electric current modes used during biliary sphincterotomy. METHODS: From October 2019 to August 2021, consecutive patients with native papilla undergoing ERCP with biliary sphincterotomy were randomized to either the pure cut or endocut after cannulation. The primary outcome was PEP incidence. Secondary outcomes included intraprocedural and delayed bleeding, infection, and perforation. RESULTS: A total of 550 patients were randomized (272 pure cut and 278 endocut). The overall PEP rate was 4.0% and significantly higher in the endocut group (5.8% vs 2.2%, P = 0.034). Univariate analysis revealed >5 attempts (P = 0.004) and endocut mode (P = 0.034) as risk factors for PEP. Multivariate analysis revealed >5 attempts (P = 0.005) and a trend for endocut mode as risk factors for PEP (P = 0.052). Intraprocedural bleeding occurred more often with pure cut (P = 0.018), but all cases were controlled endoscopically during the ERCP. Delayed bleeding was more frequent with endocut (P = 0.047). There was no difference in perforation (P = 1.0) or infection (P = 0.4999) between the groups. DISCUSSION: Endocut mode may increase thermal injury leading to higher rates of PEP and delayed bleeding, whereas pure cut is associated with increased intraprocedural bleeding without clinical repercussion. The electric current mode is not related to perforation or infection. Further RCT assessing the impact of electric current on AE with overlapping preventive measures such as rectal nonsteroidal anti-inflammatory drugs and hyperhydration are needed. The study was submitted to the Brazilian Clinical Trials Platform (http://www.ensaiosclinicos.gov.br) under the registry number RBR-5d27tn.

Pre-examination measures, during the examination and after the examination are the key to technical and clinical success with a decrease in adverse events. Several studies have debated on the subject, however, numerous topics remain controversial, such as the effectiveness of prophylactic medications and the amylase dosage time. This review was designed to provide an update on the current scientific evidence regarding PEP available in the literature.
