    A comparison of the efficiency of 22G versus 25G needles in EUS-FNA for solid pancreatic mass assessment: A systematic review and meta-analysis
    (2018) GUEDES, Hugo Goncalo; MOURA, Diogo Turiani Hourneaux de; DUARTE, Ralph Braga; CORDERO, Martin Andres Coronel; SANTOS, Marcos Eduardo Lera dos; CHENG, Spencer; MATUGUMA, Sergio Eiji; CHAVES, Dalton Marques; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux de
    Our aim in this study was to compare the efficiency of 25G versus 22G needles in diagnosing solid pancreatic lesions by EUS-FNA. We performed a systematic review and meta-analysis. Studies were identified in five databases using an extensive search strategy. Only randomized trials comparing 22G and 25G needles were included. The results were analyzed by fixed and random effects. A total of 504 studies were found in the search, among which 4 randomized studies were selected for inclusion in the analysis. A total of 462 patients were evaluated (233: 25G needle/229: 22G needle). The diagnostic sensitivity was 93% for the 25G needle and 91% for the 22G needle. The specificity of the 25G needle was 87%, and that of the 22G needle was 83%. The positive likelihood ratio was 4.57 for the 25G needle and 4.26 for the 22G needle. The area under the sROC curve for the 25G needle was 0.9705, and it was 0.9795 for the 22G needle, with no statistically significant difference between them (p=0.497). Based on randomized studies, this meta-analysis did not demonstrate a significant difference between the 22G and 25G needles used during EUS-FNA in the diagnosis of solid pancreatic lesions.

    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 de
    INTRODUCTION: 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.

    Homemade endoscopic vacuum therapy device for the management of transmural gastrointestinal defects
    (2023) MOURA, Diogo Turiani Hourneaux de; HIRSCH, Bruno Salomao; MCCARTY, Thomas R.; SANTOS, Marcos Eduardo dos; GUEDES, Hugo Goncalo; GOMES, Guilherme Francisco; MEDEIROS, Flaubert Sena de; MOURA, Eduardo Guimaraes Hourneaux de
    ObjectivesEndoscopic vacuum therapy (EVT) possesses a unique mechanism of action providing a less invasive alternative for the management of transmural gastrointestinal defects (TGID). This study evaluates the efficacy and safety of a novel homemade EVT (H-EVT) for the treatment of TGID. MethodsRetrospective multicenter study including patients who underwent H-EVT for TGID between January 2019 and January 2022. Main outcomes included technical and clinical success as well as safety outcomes. Subgroup analyses were included by defect location and classification. Logistic regression analyses were performed to determine predictors for successful closure. ResultsA total of 144 patients were included. Technical success was achieved in all patients, with clinical success achieved in 88.89% after a mean of 3.49 H-EVT exchanges over an average of 23.51 days. After excluding 10 cases wherein it was not possible to achieve negative pressure, successful closure occurred in 95.52% of patients. Time to clinical success was less for defects caused by endoscopic (hazard ratio [HR] 0.63; 95% confidence interval [CI] 0.33-1.20) compared to surgical procedures and for patients with simultaneous intracavitary and intraluminal H-EVT placement (HR 0.70; 95% CI 0.55-0.91). Location and classification of defect did not impact clinical success rate. Simultaneous placement of both an intraluminal and intracavitary H-EVT (odds ratio 3.08; 95% CI 1.19-7.95) was a significant predictor of clinical success. Three device-related adverse events (2.08%) occurred. ConclusionsThe use of the H-EVT is feasible, safe, and effective for the management of TGID.

    EUS-FNA versus ERCP for tissue diagnosis of suspect malignant biliary strictures: a prospective comparative study
    (2018) MOURA, Diogo Turiani Hourneaux; GUIDAMARAES, Eduardo; MOURA, Hourneaux de; MATUGUMA, Sergio Eiji; SANTOS, Marcos Eduardo dos; MOURA, Eduardo Turiani Hourneaux; BARACAT, Felipe Iankelevich; ARTIFON, Everson L. A.; CHENG, Spencer; BERNARDO, Wanderley Marque; CHACON, Danielle; TANIGAWA, Ryan; JUKEMURA, Jose
    Background and study aims Biliary strictures are frequently a challenging clinical scenario and the anatomopathological diagnosis is essential in the therapeutic management, whether for curative or palliative purposes. The acquisition of specimens is necessary since many benign diseases mimic biliopancreatic neoplasms. Endscopic retrograde cholangiopancreatography (ERCP) is the traditionally used method despite the low sensitivity of biliary brush cytology and forceps biopsy. On the other hand, several studies reported good accuracy rates using endoscopic ultrasound- guided fine-needle aspiration (EUS-FNA). The aim of this prospective study was to compare, the accuracy of EUS-FNA and ERCP for tissue sampling of biliary strictures. Patients and methods After performing the sample size calculation, 50 consecutive patients with indeterminate biliary strictures were included to undergo ERCP and EUS on the same sedation. The gold-standard was surgery or 6 months' follow-up. Evaluation of the diagnostic indices (sensitivity, specificity, positive and negative predictive value, positive and negative likelihood ratio), concordance and adverse events among the methods were performed. Also, subtype analyses of the techniques, anatomical localization and size of the lesion were included. Results The final diagnoses reported in 50 patients were 47 malignant, 1 suspicious and 2 benign lesions. 31 lesions were extraductal and 19 intraductal, 35 were distal and 15 proximal strictures. In the intention-to-treat analysis, the sensitivity and accuracy of EUS-FNA were superior than ERCP tissue sampling (93,8%, 94% vs. 60,4%, 62%, respectively) (P = 0.034), with similar adverse events. There was no concordance between the methods and combining both methods improved the sensitivity and accuracy for 97.9% and 98%, respectively. In the subtype analyses, the EUS-FNA was superior, with a higher accuracy than ERCP tissue sampling in evaluating extraductal lesions (100% vs. 54.8 %, P = 0.019) and in those larger than 1.5 cm (95.8% vs. 61.9%, P = 0.031), but were similar in evaluating intraductal lesions and lesions smaller than 1.5 cm. There was no significant difference between the methods in the analyzes of proximal, distal and pancreatic lesions. Conclusion EUS-FNA is better than ERCP with brush cytology and intraductal forceps biopsy in diagnosing malignant biliary strictures, mainly in the assessment of extraductal lesions and in those larger than 1.5 cm. Combining ERCP with tissue sampling and EUS-FNA is feasible, the techniques have similar complication rates, and the combination greatly improves diagnostic accuracy.

    Pancreatitis after endoscopic retrograde cholangiopancreatography: A narrative review
    (2021) RIBEIRO, Igor Braga; MONTE JUNIOR, Epifanio Silvino do; MIRANDA NETO, Antonio Afonso; PROENCA, Igor Mendonca; MOURA, Diogo Turiani Hourneaux de; MINATA, Mauricio Kazuyoshi; IDE, Edson; SANTOS, Marcos Eduardo Lera dos; LUZ, Gustavo de Oliveira; MATUGUMA, Sergio Eiji; CHENG, Spencer; BARACAT, Renato; MOURA, Eduardo Guimaraes Hourneaux de
    Acute post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) is a feared and potentially fatal complication that can be as high as up to 30% in high-risk patients. 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.

    Efficacy of digital single-operator cholangioscopy in the visual interpretation of indeterminate biliary strictures: a systematic review and meta-analysis
    (2020) OLIVEIRA, Pedro Victor Aniz Gomes de; MOURA, Diogo Turiani Hourneaux de; RIBEIRO, Igor Braga; BAZARBASHI, Ahmad Najdat; FRANZINI, Tomazo Antonio Prince; SANTOS, Marcos Eduardo Lera dos; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux de
    Objective Indeterminate biliary strictures remain a significant diagnostic challenge. Digital single-operator cholangioscopy (D-SOC) incorporates digital imaging which enables higher resolution for better visualization and diagnosis of biliary pathology. We aimed to conduct a systematic review and meta-analysis of available literature in an attempt to determine the efficacy of D-SOC in the visual interpretation of indeterminate biliary strictures. Material and methods Electronic searches were performed using Medline (PubMed), EMBASE, and Cochrane Library. All D-SOC studies that reported the diagnostic performance in visual interpretation of indeterminate biliary strictures and biliary malignancies were included. The Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2 was used to evaluate the quality of the included studies. All data were extracted and pooled to construct a 2 x 2 table. The visual interpretation of D-SOC was compared to resected surgical specimens or clinical follow-up in the included patients. Pooled sensitivity, specificity, positive predictive value, negative predictive value, prevalence, positive likelihood ratio (+LR), negative likelihood ratio (-LR), and diagnostic odds ratio (OR) were calculated. The summarized receiver operating characteristic (SROC) curve corresponding with the area under the curve (AUC) was also analyzed. Results The search yielded 465 citations. Of these, only six studies with a total of 283 procedures met inclusion criteria and were included in the meta-analysis. The overall pooled sensitivity and specificity of D-SOC in the visual interpretation of biliary malignancies was 94% (95% CI 89-97) and 95% (95%CI 90-98), respectively, while +LR, -LR, diagnostic OR, and AUC were 15.20 (95%CI 5.21-44.33), 0.08 (95%CI 0.04-0.14), 308.83 (95%CI 106.46-872.82), and 0.983, respectively. The heterogeneity among 6 included studies was moderate for specificity (I-2 = 0.51) and low for sensitivity (I-2 = 0.17) and diagnostic OR (I-2 = 0.00). Conclusion D-SOC is associated with high sensitivity and specificity in the visual interpretation of indeterminate biliary strictures and malignancies. D-SOC should be considered routinely in the diagnostic workup of indeterminate biliary lesions.

    Propofol vs traditional sedatives for sedation in endoscopy: A systematic review and meta-analysis
    (2019) DELGADO, Aureo Augusto de Almeida; MOURA, Diogo Turiani Hourneaux de; RIBEIRO, Igor Braga; BAZARBASHI, Ahmad Najdat; SANTOS, Marcos Eduardo Lera dos; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux de
    BACKGROUND Propofol is commonly used for sedation during endoscopic procedures. Data suggests its superiority to traditional sedatives used in endoscopy including benzodiazepines and opioids with more rapid onset of action and improved post-procedure recovery times for patients. However, Propofol requires administration by trained healthcare providers, has a narrow therapeutic index, lacks an antidote and increases risks of cardio-pulmonary complications. AIM To compare, through a systematic review of the literature and meta-analysis, sedation with propofol to traditional sedatives with or without propofol during endoscopic procedures. METHODS A literature search was performed using MEDLINE, Scopus, EMBASE, the Cochrane Library, Scopus, LILACS, BVS, Cochrane Central Register of Controlled Trials, and The Cumulative Index to Nursing and Allied Health Literature databases. The last search in the literature was performed on March, 2019 with no restriction regarding the idiom or the year of publication. Only randomized clinical trials with full texts published were included. We divided sedation therapies to the following groups: (1) Propofol versus benzodiazepines and/or opiate sedatives; (2) Propofol versus Propofol with benzodiazepine and/or opioids; and (3) Propofol with adjunctive benzodiazepine and opioid versus benzodiazepine and opioid. The following outcomes were addressed: Adverse events, patient satisfaction with type of sedation, endoscopists satisfaction with sedation administered, dose of propofol administered and time to recovery post procedure. Meta-analysis was performed using RevMan5 software version 5.39. RESULTS A total of 23 clinical trials were included (n = 3854) from the initial search of 6410 articles. For Group I (Propofol vs benzodiazepine and/or opioids): The incidence of bradycardia was not statistically different between both sedation arms (RD: -0.01, 95%CI: -0.03-+0.01, I-2: 22%). In 10 studies, the incidence of hypotension was not statistically difference between sedation arms (RD: 0.01, 95%CI: -0.02-+0.04, I-2: 0%). Oxygen desaturation was higher in the propofol group but not statistically different between groups (RD: -0.03, 95%CI: -0.06-+0.00, I-2: 25%). Patients were more satisfied with their sedation in the benzodiazepine + opioid group compared to those with monotherapy propofol sedation (MD: +0.89, 95%CI: +0.62-+1.17, I-2: 39%). The recovery time after the procedure showed high heterogeneity even after outlier withdrawal, there was no statistical difference between both arms (MD: -15.15, 95%CI: -31.85-+1.56, I-2: 99%). For Group II (Propofol vs propofol with benzodiazepine and/or opioids): Bradycardia had a tendency to occur in the Propofol group with benzodiazepine and/or opioid-associated (RD: -0.08, 95%CI: -0.13--0.02, I-2: 59%). There was no statistical difference in the incidence of bradycardia (RD: -0.00, 95%CI: -0.08-+0.08, I-2: 85%), desaturation (RD: -0.00, 95%CI: -0.03-+0.02, I-2: 44%) or recovery time (MD: -2.04, 95%CI: -6.96-+2.88, I-2: 97%) between sedation arms. The total dose of propofol was higher in the propofol group with benzodiazepine and/or opiates but with high heterogeneity. (MD: 70.36, 95%CI: +53.11-+87.60, I-2: 61%). For Group III (Propofol with benzodiazepine and opioid vs benzodiazepine and opioid): Bradycardia and hypotension was not statistically significant between groups (RD: -0.00, 95%CI: -0.002-+0.02, I-2: 3%; RD: 0.04, 95%CI: -0.05-+0.13, I-2: 77%). Desaturation was evaluated in two articles and was higher in the propofol + benzodiazepine + opioid group, but with high heterogeneity (RD: 0.15, 95%CI: 0.08-+0.22, I-2: 95%). CONCLUSION This meta-analysis suggests that the use of propofol alone or in combination with traditional adjunctive sedatives is safe and does not result in an increase in negative outcomes in patients undergoing endoscopic procedures.
