    The Effectiveness and Safety of the Duodenal-Jejunal Bypass Liner (DJBL) for the Management of Obesity and Glycaemic Control: a Systematic Review and Meta-Analysis of Randomized Controlled Trials
    (2023) YVAMOTO, Erika Yuki; MOURA, Diogo Turiani Hourneaux de; PROENCA, Igor Mendonca; MONTE JUNIOR, Epifanio Silvino do; RIBEIRO, Igor Braga; RIBAS, Pedro Henrique Boraschi Vieira; HEMERLY, Matheus Candido; OLIVEIRA, Victor Lira de; SANCHEZ-LUNA, Sergio A.; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux de
    Introduction The duodenal-jejunal bypass liner (DJBL) is a less-invasive treatment of obesity and type 2 diabetes mellitus (T2DM). Methods This is a systematic review and meta-analysis including randomized clinical trials (RCTs) comparing DJBL versus sham or pharmacotherapies aiming to evaluate the effectiveness and safety of DJBL. Results Ten RCTs (681 patients) were included. The DJBL group showed superior excess weight loss (+ 11.4% [+ 7.75 to + 15.03%], p < 0.00001) and higher decrease in HbA1c compared to the control group (- 2.73 +/- 0.5 vs. - 1.73 +/- 0.4, p = 0.0001). Severe adverse events (SAEs) occurred in 19.7%. Conclusion The DJBL did not reach the ASGE/ASMBS thresholds for the treatment of obesity. However, it is important to state that many SAEs were not really severe. Therefore, we believe this therapy plays an important role in the management obesity and T2DM.

    (2020) GUACHO, John Alexander Lata; MOURA, Diogo Turiani Hourneaux de; RIBEIRO, Igor Braga; PONTE NETO, Alberto Machado da; SINGH, Shailendra; TUCCI, Marina Gammaro Baldavira; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux de
    BACKGROUND Patients with cirrhosis frequently require sedation for elective endoscopic procedures. Several sedation protocols are available, but choosing an appropriate sedative in patients with cirrhosis is challenging. AIM To conduct a systematic review and meta-analysis to compare propofol and midazolam for sedation in patients with cirrhosis during elective endoscopic procedures in an attempt to understand the best approach. METHODS This systematic review and meta-analysis was conducted using the PRISMA guidelines. Electronic searches were performed using MEDLINE, EMBASE, Central Cochrane, LILACS databases. Only randomized control trials (RCTs) were included. The outcomes studied were procedure time, recovery time, discharge time, and adverse events (bradycardia, hypotension, and hypoxemia). The risk of bias assessment was performed using the Revised Cochrane Risk-of-Bias tool for randomized trials (RoB-2). Quality of evidence was evaluated by GRADEpro. The meta-analysis was performed using Review Manager. RESULTS The search yielded 3,576 records. Out of these, 8 RCTs with a total of 596 patients (302 in the propofol group and 294 in the midazolam group) were included for the final analysis. Procedure time was similar between midazolam and propofol groups (MD: 0.25, 95%CI: -0.64 to 1.13,P= 0.59). Recovery time (MD: -8.19, 95%CI: -10.59 to -5.79,P< 0.00001). and discharge time were significantly less in the propofol group (MD: -12.98, 95%CI: -18.46 to -7.50,P< 0.00001). Adverse events were similar in both groups (RD: 0.02, 95%CI: 0-0.04,P= 0.58). Moreover, no significant difference was found for bradycardia (RD: 0.03, 95%CI: -0.01 to 0.07,P= 0.16), hypotension (RD: 0.03, 95%CI: -0.01 to 0.07,P= 0.17), and hypoxemia (RD: 0.00, 95%CI: -0.04 to 0.04,P= 0.93). Five studies had low risk of bias, two demonstrated some concerns, and one presented high risk. The quality of the evidence was very low for procedure time, recovery time, and adverse events; while low for discharge time. CONCLUSION This systematic review and meta-analysis based on RCTs show that propofol has shorter recovery and patient discharge time as compared to midazolam with a similar rate of adverse events. These results suggest that propofol should be the preferred agent for sedation in patients with cirrhosis.

    (2020) MIRANDA NETO, Antonio Afonso de; MOURA, Diogo Turiani Hourneaux de; RIBEIRO, Igor Braga; KHAN, Ahmad; SINGH, Shailendra; PONTE NETO, Alberto Machado da; MADRUGA NETO, Antonio Coutinho; MONTE JUNIOR, Epifanio Silvino do; TUSTUMI, Francisco; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux de
    Background Endoscopic sleeve gastroplasty (ESG) has emerged as a promising technique in endoscopic bariatric and metabolic therapies (EBMTs). We aimed to perform a systematic review and meta-analysis to provide an update on its efficacy and safety. Methods This is a systematic review and meta-analysis was performed following the PRISMA guidelines. MEDLINE, Cochrane, EMBASE, and LILACS were searched to identify the studies related to ESG. Results Eleven studies with a total of 2170 patients were included. The average BMI pre-ESG was 35.78 kg/m(2). Pooled mean %TWL observed at 6, 12, and 18 months was 15.3%, 16.1%, and 16.8% respectively. Pooled mean %EWL at 6, 12, and 18 months was 55.8%, 60%, and 73% respectively. No procedure-related mortality was reported. Conclusion ESG is a safe and effective procedure for primary obesity therapy with promising short- and mid-term results.

    Role of endoscopic vacuum therapy in the management of gastrointestinal transmural defects
    (2019) MOURA, Diogo Turiani Hourneaux de; MOURA, Bruna Furia Buzetti Hourneaux de; MANFREDI, Michael A.; HATHORN, Kelly E.; BAZARBASHI, Ahmad N.; RIBEIRO, Igor Braga; MOURA, Eduardo Guimaraes Hourneaux de; THOMPSON, Christopher C.
    A gastrointestinal (GI) transmural defect is defined as total rupture of the GI wall, and these defects can be divided into three categories: perforations, leaks, and fistulas. Surgical management of these defects is usually challenging and may be associated with high morbidity and mortality rates. Recently, several novel endoscopic techniques have been developed, and endoscopy has become a first-line approach for therapy of these conditions. The use of endoscopic vacuum therapy (EVT) is increasing with favorable results. This technique involves endoscopic placement of a sponge connected to a nasogastric tube into the defect cavity or lumen. This promotes healing via five mechanisms, including macrodeformation, microdeformation, changes in perfusion, exudate control, and bacterial clearance, which is similar to the mechanisms in which skin wounds are treated with commonly employed wound vacuums. EVT can be used in the upper GI tract, small bowel, biliopancreatic regions, and lower GI tract, with variable success rates and a satisfactory safety profile. In this article, we review and discuss the mechanism of action, materials, techniques, efficacy, and safety of EVT in the management of patients with GI transmural defects.

    Pain relief in chronic pancreatitis: endoscopic or surgical treatment? a systematic review with meta-analysis
    (2021) MENDIETA, Pastor Joaquin Ortiz; SAGAE, Vitor Massaro Takamatsu; RIBEIRO, Igor Braga; MOURA, Diogo Turiani Hourneaux de; SCATIMBURGO, Maria Vitoria Cury Vieira; HIRSCH, Bruno Salomao; ROCHA, Rodrigo Silva de Paula; VISCONTI, Thiago Arantes de Carvalho; SANCHEZ-LUNA, Sergio A.; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux de
    Background and aims Pain is one of the consequences of chronic pancreatitis (CP) that has the greatest impact on the quality of life of patients. Endoscopic and surgical interventions, by producing a decrease in intraductal pancreatic pressure, can provide pain relief. This is the first systematic review that includes only randomized clinical trials (RTCs) comparing outcomes in the short-term (less than 2 years) and long-term (more than 2 years) between these two types of interventions. Material and methods A comprehensive search of multiple electronic databases to identify RTCs comparing short and long-term pain relief, procedural complications, and days of hospitalization between endoscopic and surgical interventions was performed following the PRISMA guidelines. Results Three RCTs evaluating a total of 199 patients (99 in the endoscopy group and 100 in the surgery group) were included in this study. Surgical interventions provided complete pain relief, with statistical difference, in the long-term (16,4% vs 35.7%; RD 0.19; 95% CI 0.03-0.35; p = 0.02; I2 = 0%), without significant difference in short-term (17.5% vs 31.2%; RD 0.14; 95% CI -0.01-0.28; p = 0.07; I2 = 0%) when compared to endoscopy. There was no statistical difference in short-term (17.5% vs 28.1%; RD 0.11; 95% CI -0.04-0.25; p = 0.15; I2 = 0%) and long-term (34% vs 41.1%; RD 0.07; 95% CI -0.10-0.24; p = 0.42; I2 0%) in partial relief of pain between both interventions. In the short-term, both complications (34.9% vs 29.7%; RD 0.05; 95% CI -0.10-0.21; p = 0.50; I2 = 48%) and days of hospitalization (MD -1.02; 95% CI -2.61-0.58; p = 0.21; I2 = 0%) showed no significant differences. Conclusion Surgical interventions showed superior results when compared to endoscopy in terms of complete long-term pain relief. The number of complications and length of hospitalization in both groups were similar.

    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.

    Endoscopic ultrasound (EUS)-guided cholecystostomy versus percutaneous cholecystostomy (PTC) in the management of acute cholecystitis in patients unfit for surgery: a systematic review and meta-analysis
    (2023) HEMERLY, Matheus Candido; MOURA, Diogo Turiani Hourneaux de; MONTE JUNIOR, Epifanio Silvino do; PROENCA, Igor Mendonca; RIBEIRO, Igor Braga; YVAMOTO, Erika Yuki; RIBAS, Pedro Henrique Boraschi Vieira; SANCHEZ-LUNA, Sergio A.; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux de
    Background and aim Surgical cholecystectomy is the gold standard strategy for the management of acute cholecystitis (AC). However, some patients are considered unfit for surgery due to certain comorbid conditions. As such, we aimed to compare less invasive treatment strategies such as endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) and percutaneous gallbladder drainage (PT-GBD) for the management of patients with AC who are suboptimal candidates for surgical cholecystectomy. Methods A comprehensive search of multiple electronic databases was performed to identify all the studies comparing EUS-GBD versus PT-GBD for patients with AC who were unfit for surgery. A subgroup analysis was also performed for comparison of the group undergoing drainage via cautery-enhanced lumen-apposing metal stents (LAMS) versus PT-GBD. The outcomes included technical and clinical success, adverse events (AEs), recurrent cholecystitis, reintervention, and hospital readmission. Results Eleven studies including 1155 patients were included in the statistical analysis. There was no difference between PT-GBD and EUS-GBD in all the evaluated outcomes. On the subgroup analysis, the endoscopic approach with cautery-enhanced LAMS was associated with lower rates of adverse events (RD = - 0.33 (95% CI - 0.52 to - 0.14; p = 0.0006), recurrent cholecystitis (- 0.05 RD (95% CI - 0.09 to - 0.02; p = 0.02), and hospital readmission (- 0.36 RD (95% CI-0.70 to - 0.03; p = 0.03) when compared to PT-GBD. All other outcomes were similar in the subgroup analyses. Conclusions EUS-GBD using cautery-enhanced LAMS is superior to PT-GBD in terms of safety profile, recurrent cholecystitis, and hospital readmission rates in the management of patients with acute cholecystitis who are suboptimal candidates for cholecystectomy. However, when cautery-enhanced LAMS are not used, the outcomes of EUS-GBD and PT-GBD are similar. Thus, EUS-GBD with cautery-enhanced LAMS should be considered the preferable approach for gallbladder drainage for this challenging population.

    Endoscopic Vacuum Therapy (EVT) for the Treatment of Post-Bariatric Surgery Leaks and Fistulas: a Systematic Review and Meta-analysis
    (2022) INTRIAGO, Josselyn Mariana Vera; MOURA, Diogo Turiani Hourneaux de; MONTE JUNIOR, Epifanio Silvino do; PROENCA, Igor Mendonca; RIBEIRO, Igor Braga; SANCHEZ-LUNA, Sergio A.; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux de
    Bariatric surgery remains the most effective treatment for morbid obesity and its comorbidities. However, post-surgical leaks and fistulas can occur in about 1-5% of patients, with challenging treatment approaches. Endoscopic vacuum therapy (EVT) has emerged as a promising tool due to its satisfactory results and accessibility. In this first systematic review and meta-analysis on the subject, EVT revealed rates of 87.2% clinical success, 6% moderate adverse events, and 12.5% system dislodgements, requiring 6.47 EVT system exchanges every 4.39 days, with a dwell time of 25.67 days and a total length of hospitalization of 44.43 days. Although our results show that EVT is a safe and effective therapy for post-surgical leaks and fistulas, they should be interpreted with caution due to the paucity of available data.

    Endoscopic Ultrasound-Guided Fine Needle Aspiration and Endoscopic Retrograde Cholangiopancreatography-Based Tissue Sampling in Suspected Malignant Biliary Strictures: A Meta-Analysis of Same-Session Procedures
    (2020) MOURA, Diogo Turiani Hourneax de; RYOU, Marvin; MOURA, Eduardo Guimaraes Hourneaux de; RIBEIRO, Igor Braga; BERNARDO, Wanderlei Marques; THOMPSON, Christopher C.
    Background/Aims: The diagnosis of biliary strictures can be challenging. There are no systematic reviews studying same-session endoscopic retrograde cholangiopancreatography (ERCP)-based tissue sampling and endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for the diagnosis of biliary strictures. Methods: A systematic review was conducted on studies analyzing same-session EUS and ERCP for tissue diagnosis of suspected malignant biliary strictures. The primary outcome was the accuracy of each method individually compared to the two methods combined. The secondary outcome was the accuracy of each method in pancreatic and biliary etiologies. In the meta-analysis, we used Forest plots, summary receiver operating characteristic curves, and estimates of the area under the curve for intention-to-treat analysis. Results: Of the 12,132 articles identified, six were included, resulting in a total of 497 patients analyzed. The sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and accuracy of the association between the two methods were: 86%, 98%, 12.50, 0.17, and 96.5%, respectively. For the individual analysis, the sensitivity, specificity and accuracy of EUS-FNA were 76%, 100%, and 94.5%, respectively; for ERCP-based tissue sampling, the sensitivity, specificity, and accuracy were 58%, 98%, and 78.1%, respectively. For pancreatic lesions, EUS-FNA was superior to ERCP-based tissue sampling. However, for biliary lesions, both methods had similar sensitivities. Conclusions: Same-session EUS-FNA and ERCP-based tissue sampling is superior to either method alone in the diagnosis of suspected malignant biliary strictures. Considering these results, combination sampling should be performed when possible.

    Use of omental patch and endoscopic closure technique as an alternative to surgery after endoscopic full thickness resection of gastric intestinal stromal tumors: A series of cases
    (2020) SACHDEV, Amit H.; IQBAL, Shahzad; RIBEIRO, Igor Braga; MOURA, Diogo Turiani Hourneaux de
    BACKGROUND Gastrointestinal stromal tumors (GISTs) originate from interstitial cells of Cajal. GISTs can occur anywhere along the gastrointestinal tract. Large lesions have traditionally been removed surgically. However, with recent innovations in advanced endoscopy, GISTs located within the stomach are now removed endoscopically. We describe a new innovative endoscopic technique to close large and hard to access defects after endoscopic full-thickness resection of gastric GISTs. CASE SUMMARY We present a series of three patients who were diagnosed with a gastric GIST. All patients underwent full-thickness endoscopic resection. In all cases, for closure of the surgical bed, conventional endoscopic techniques including hemoclips, endoloop and suturing were unsuccessful. We performed a new technique in which we pulled omental fat into the gastric lumen and completely closed the defect using endoscopic devices. All patients performed well post-procedure and computed tomography was carried out one day after the procedures which showed no extravasation of contrast. CONCLUSION The omental plug technique may be used as an alternative to surgery in selected cases of gastric perforation.
