    Managing adverse events after endoscopic ultrasound-guided drainage of the biliary tract and pancreatic fluid collections: Narrative review (with video)
    (2022) FUNARI, Mateus Pereira; RIBEIRO, Igor Braga; SANTOS, Marcos Eduardo Lera dos; MATUGUMA, Sergio Eiji; MOURA, Eduardo Guimaraes Hourneaux de
    Endoscopic ultrasound (EUS)-guided therapeutic procedures have become increasingly common in clinical practice. The development of EUS-guided fine needle aspiration cytology led to the concept of interventional EUS. However, it carries a considerable risk of adverse events (AEs), which occur in approximately 23% of the procedures performed for the drainage of pancreatic fluid collections and 2.5-37.0% of those performed for drainage of the biliary tract. Although the vast majority of AEs occurring after EUS-guided drainage are mild, a deep understanding of such events is necessary for their appropriate management. Because EUS-guided drainage is a novel procedure, there have been few studies of the topic. To our knowledge, this is the first narrative review that focuses on the management and resolution of AEs occurring after EUS-guided drainage of pancreatic fluid collections or the biliary tract. We also include an explanatory video.

    DIAGNOSTIC ACCURACY OF GASTROPANEL® FOR ATROPHIC GASTRITIS IN BRAZILIAN SUBJECTS AND THE EFFECT OF PROTON PUMP INHIBITORS
    (2020) MATTAR, Rejane; MARQUES, Sergio Barbosa; RIBEIRO, Igor Braga; VISCONTI, Thiago Arantes de Carvalho; FUNARI, Mateus; DE MOURA, Eduardo Guimarães Hourneaux
    ABSTRACT BACKGROUND: It has been proposed that the combination of gastrin-17 (G-17), pepsinogens I and II (PGI and PGII), and anti-Helicobacter pylori (H. pylori) antibodies (GastroPanel®, BIOHIT HealthCare, Helsinki, Finland) could serve as biomarkers of atrophic gastritis. OBJECTIVE: This study aimed to ensure the diagnostic accuracy of GastroPanel® and evaluate the effect of proton pump inhibitors (PPIs) on these biomarkers. METHODS: Dyspeptic patients who underwent gastrointestinal endoscopy were enrolled in the present study. Histological findings, which were the gold standard to stratify groups, were as follows: no atrophy (controls); antrum atrophy; corpus atrophy; multifocal atrophy; and neoplasia. G-17, PGI, PGII, and anti-H. pylori immunoglobulin (Ig)G antibodies were assayed using commercially available kits. The ratio of PGI/PGII was calculated. RESULTS: Among 308 patients, 159 (51.6%) were PPI users. The overall prevalence of atrophy was 43.8% (n=135). Ninety-two (29.9%) patients were H. pylori positive according to anti-H. pylori IgG levels. G-17 levels were not low in those with antrum atrophy but were high in those with corpus and multifocal atrophies. PGI levels were significantly lower in those with corpus and multifocal atrophies. The sensitivity of PGI <30 µg/L to detect corpus atrophy was 50% (95% CI 27.8-72.1%), with a specificity of 93.2% (95% CI 84.3-97.5%), a positive likelihood ratio of 7.4 (95% CI 2.9-19.2), and a negative likelihood ratio of 0.5 (95% CI 0.3-0.8). A small number of subjects (n=6) exhibited moderate to intense atrophy (4%), among whom 66.7% exhibited decreased PGI levels. PPI significantly increased the levels of G-17 and PGI, except in those with corpus and multifocal atrophies, in whom PGI levels were not increased by PPIs. CONCLUSION: GastroPanel® (Gastrin-17, PGI, and PGI/PGII ratio) did not demonstrate high sensitivity for detecting gastric atrophy.

    Endoscopic Band Ligation Versus Argon Plasma Coagulation in the Treatment of Gastric Antral Vascular Ectasia: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
    (2021) HIRSCH, Bruno Salomao; RIBEIRO, Igor Braga; FUNARI, Mateus Pereira; MOURA, Diogo Turiani Hourneaux de; MATUGUMA, Sergio Eiji; SANCHEZ-LUNA, Sergio A.; MANCINI, Fabio Catache; OLIVEIRA, Guilherme Henrique Peixoto de; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux de
    Background/Aims: Argon plasma coagulation (APC) is the most commonly used endoscopic treatment for gastric antral vascular ectasia (GAVE). Endoscopic band ligation (EBL) has emerged as an alternative therapy. Our goal was to evaluate the feasibility, efficacy, and safety of APC and EBL for the treatment of GAVE. This is the first systematic review that included only randomized controlled trials (RCTs) on this topic. Methods: A comprehensive search was performed using electronic databases to identify RCTs comparing APC and EBL for the treatment of GAVE following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Results: Four RCTs were included, with a total of 204 patients. EBL was related to higher endoscopic eradication rates risk difference [RD], 0.29; 95% confidence interval [CI] [0.14, 0.44]; I-2=0%) and less bleeding recurrence than APC (RD, 0.29; 95% CI [0.15, 0.44]; I-2=0%). Patients treated with EBL required fewer blood transfusions (mean difference [MD], 1.49; 95% CI [0.28, 2.71]; I-2=96%) and hospitalizations (MD, 0.29; 95% CI [0.19, 0.39]; I-2=0%). The number of sessions required for the obliteration of lesions was higher with APC. There was no difference in the incidence of adverse events. Conclusions: EBL is superior to APC in the treatment of GAVE in terms of endoscopic eradication rates, recurrence of bleeding, and transfusion requirements.

    Rare and Fatal Gastrointestinal Mucormycosis (Zygomycosis) in COVID-19 Patient: A Case Report
    (2020) MONTE JUNIOR, Epifanio Silvino do; SANTOS, Marcos Eduardo Lera dos; RIBEIRO, Igor Braga; LUZ, Gustavo de Oliveira; BABA, Elisa Ryoka; HIRSCH, Bruno Salomao; FUNARI, Mateus Pereira; MOURA, Eduardo Guimaraes Hourneaux de
    The novel coronavirus disease (COVID-19) quickly spread to all continents. However, data regarding all the signs and symptoms of COVID-19 are insufficient. Patients with COVID-19 might present higher susceptibility to fungal coinfections. Mucormycosis is a rare and often life-threatening fungal disease characterized by vascular invasion by hyphae, resulting in thrombosis and necrosis. This is the first case report of mucormycosis in a COVID-19 patient. An 86-year-old male patient was admitted to the emergency room with acute diarrhea, cough, dyspnea, and fever from 5 days prior. Blood tests revealed a hemoglobin level of 14.3 mg/dL. Five days following the admission, the patient presented with melena and a hemoglobin level of 5.6 mg/dL. A transfusion of three units of red blood cells was required. Esophagogastroduodenoscopy revealed two giant gastric ulcers with necrotic debris and a deep hemorrhagic base without active bleeding. Furthermore, biopsies confirmed mucormycosis. Despite intensive care, the patient died 36 hours after the esophagogastroduodenoscopy.

    Endoscopic submucosal dissection versus transanal endoscopic surgery for the treatment of early rectal tumor: a systematic review and meta-analysis
    (2020) SAGAE, Vitor Massaro Takamatsu; RIBEIRO, Igor Braga; MOURA, Diogo Turiani Hourneaux de; BRUNALDI, Vitor Ottoboni; LOGIUDICE, Fernanda Prado; FUNARI, Mateus Pereira; BABA, Elisa Ryoka; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux de
    Background Minimally invasive treatment of early-stage rectal lesion has presented good results, with lower morbidity than surgical resection. Transanal endoscopic microsurgery (TEM) and transanal minimally invasive surgery (TAMIS) are the main methods of transanal surgery. However, endoscopic submucosal dissection (ESD) has been gaining ground because it allows en bloc resections with low recurrence rates. The aim of this study was to analyze ESD in comparison with transanal endoscopic surgery. Methods We searched MEDLINE, EMBASE, SciELO, Cochrane CENTRAL, and Lilacs/Bireme with no restrictions on the date or language of publication. The outcomes evaluated were recurrence rate, complete (R0) resection rate, en bloc resection rate, length of hospital stay, duration of the procedure, and complication rate. Results Six retrospective cohort studies involving a collective total of 326 patients-191 in the ESD group and 135 in the transanal endoscopic surgery group were conducted. There were no statistically significant differences between the groups for any of the outcomes evaluated. Conclusions For the minimally invasive treatment of early rectal tumor, ESD and surgical techniques do not differ in terms of local recurrence, en bloc resection rate, R0 resection rate, duration of the procedure, length of hospital stay, or complication rate, however, evidence is very low.

    Cholangioscopy-guided lithotripsy vs. conventional therapy for complex bile duct stones: a systematic review and meta-analysis
    (2020) GALETTI, Facundo; MOURA, Diogo Turiani Hourneaux de; RIBEIRO, Igor Braga; FUNARI, Mateus Pereira; CORONEL, Martin; SACHDE, Amit H.; BRUNALDI, Vitor Ottoboni; FRANZINI, Tomazo Prince; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux de
    Introduction: Endoscopic removal of common bile duct stones has a high success rate ranging from 85% to 95%. Bile duct stones >15 mm are difficult and frequently require lithotripsy. Peroral cholangioscopy (POC) allows lithotripsy with similar success rates. Aim: To determine the efficacy and safety of cholangioscopy-guided lithotripsy used in the treatment of difficult to remove bile duct stones vs. conventional therapy. Methods: Search was based in Medlin, Embase, Cochrane Central, Lilacs/Bireme. Studies enrolling patients referred for the removal of difficult bile duct stones via POC were considered eligible. Two analyses were carried out separately, one included randomized controlled trials (RCTs) and another observational studies. Results: Forty-six studies were selected (3 RTC and 43 observational). In the analysis there was no statistical significant difference between successful endoscopic clearance (RD=-0.02 CI: -0.17, 0.12/I-2-0%), mean fluoroscopy time (MD--0.14 CI -1.60, 1.32/I-2 -21%) and adverse events rates (RD=-0.06 CI: -0.14, 0.02/I-2=0%), by contrast, the mean procedure time favored conventional therapy with statistical significance (MD-27.89 CI: 16.68, 39.10/I-2-096). In observational studies, the successful endoscopic clearance rate was 8829% (CI95: 86.996-90.7%), the first session successful endoscopic clearance rate was 72.7 % (CI95: 69.9%-75.3%), the mean procedure time was 47.50 +/- 6 min for session and the number of sessions to clear bile duct was 15 +/- 0.18. The adverse event rate was 8.7% (C195: 7%-10.9%). Concussions: For complex common bile duct stones, cholangioscopy-guided lithotripsy has a success rate that is similar to traditional ERCP techniques in terms of therapeutic success, adverse event rate and means fluoroscopy time. Conventional ERCP methods have a shorter mean procedure time.

    Use of an electromagnetic-guided device to assist with post-pyloric placement of a nasoenteral feeding tube: A systematic review and meta-analysis
    (2022) MANCINI, Fabio Catache; MOURA, Diogo Turiani Hourneaux de; FUNARI, Mateus Pereira; RIBEIRO, Igor Braga; NETO, Fernando Lopes Ponte; MENDIETA, Pastor Joaquin Ortiz; MCCARTY, Thomas R.; BERNARDO, Wanderley Marques; NAHAS, Sergio Carlos; MOURA, Eduardo Guimaraes Hourneaux de
    Background and study aims While endoscopic-guided placement (EGP) of a post-pyloric nasoenteral feeding tube may improve caloric intake and reduce the risk of bronchoaspiration, an electromagnetic-guided placement (EMGP) method may obviate the need for endoscopic procedures. Therefore, the primary aim of this study was to perform a systematic review and meta-analysis of randomized trials comparing the efficacy and safety of EMGP versus EGP of a post-pyloric feeding tube. Methods Protocolized searches were performed from the inception through January 2021 following PRISMA guidelines. Only randomized controlled trials were included comparing EMGP versus EGP. Study outcomes included: technical success (defined as appropriate post-pyloric positioning), tube and patient associated adverse events (AEs), time to enteral nutrition, procedure-associated cost, and procedure time. Pooled risk difference (RD) and mean difference (MD) were calculated using a fixed-effects model and heterogeneity evaluated using Higgins test (I-2). Results Four randomized trials (n =536) were included. A total of 287 patients were included in the EMGP group and 249 patients in the EGP group. There was no difference between EMGP versus EGP regarding technical success, tube-related AEs, patient-related AEs, procedure time, and time in the right position. Time to enteral nutrition favored EMGP (MD: -134.37 [-162.13, -106.61]; 1 2 =35%); with significantly decreased associated cost (MD: -127.77 (5) [-135.8-119.73]; I-2 =0%). Conclusions Based on this study, EMGP and EGP were associated with similar levels of technical success and safety as well as time to complete the procedure. Despite this, EMGP was associated with reduced cost and time to initiation of nutrition.
