    Narrow band imaging versus lugol chromoendoscopy to diagnose squamous cell carcinoma of the esophagus: a systematic review and meta-analysis
    (2017) MORITA, Flavio Hiroshi Ananias; BERNARDO, Wanderley Marques; IDE, Edson; ROCHA, Rodrigo Silva Paula; AQUINO, Julio Cesar Martins; MINATA, Mauricio Kazuyoshi; YAMAZAKI, Kendi; MARQUES, Sergio Barbosa; SAKAI, Paulo; MOURA, Eduardo Guimaraes Hourneaux de
    Background: In the early stage esophageal cancer, changes in the mucosa are subtle and pass unnoticed in endoscopic examinations using white light. To increase sensitivity, chromoscopy with Lugol's solution has been used. Technological advancements have led to the emergence of virtual methods of endoscopic chromoscopy, including narrow band imaging (NBI). NBI enhances the relief of the mucosa and the underlying vascular pattern, providing greater convenience without the risks inherent to the use of vital dye. The purpose of this systematic review and meta-analysis was to evaluate the ability of NBI to diagnose squamous cell carcinoma of the esophagus and to compare it to chromoscopy with Lugol's solution. Methods: This systematic review included all studies comparing the diagnostic accuracy of NBI and Lugol chromoendoscopy performed to identify high-grade dysplasia and/or squamous cell carcinoma in the esophagus. In the meta-analysis, we calculated and demonstrated sensitivity, specificity, and positive and negative likelihood values in forest plots. We also determined summary receiver operating characteristic (sROC) curves and estimates of the areas under the curves for both per-patient and per-lesion analysis. Results: The initial search identified 7079 articles. Of these, 18 studies were included in the systematic review and 12 were used in the meta-analysis, for a total of 1911 patients. In per-patient and per-lesion analysis, the sensitivity, specificity, and positive and negative likelihood values for Lugol chromoendoscopy were 92% and 98, 82 and 37%, 5.42 and 1.4, and 0.13 and 0.39, respectively, and for NBI were 88 and 94%, 88 and 65%, 8.32 and 2.62, and 0.16 and 0.12, respectively. There was a statistically significant difference in only specificity values, in which case NBI was superior to Lugol chromoendoscopy in both analyses. In the per-patient analysis, the area under the sROC curve for Lugol chromoendoscopy was 0.9559. In the case of NBI, this value was 0.9611; in the per-lesion analysis, this number was 0.9685 and 0.9587, respectively. Conclusions: NBI was adequate in evaluating the esophagus in order to diagnose high-grade dysplasia and squamous cell carcinoma. In the differentiation of those disorders from other esophageal mucosa alterations, the NBI was shown to be superior than Lugol.

    Comparison between Enteroscopy-Based and Laparoscopy-Assisted ERCP for Accessing the Biliary Tree in Patients with Roux-en-Y Gastric Bypass: Systematic Review and Meta-analysis
    (2018) PONTE-NETO, Alberto Machado da; BERNARDO, Wanderley M.; COUTINHO, Lara M. de A.; JOSINO, Iatagan Rocha; BRUNALDI, Vitor Ottoboni; MOURA, Diogo T. H.; SAKAI, Paulo; KUGA, Rogerio; MOURA, Eduardo G. H. de
    Although balloon-assisted enteroscopy-endoscopic retrograde cholangiopancreatography (BAE-ERCP) is a well-described means of accessing the duodenal papilla in patients with Roux-en-Y gastric bypass (RYGB), it is associated with modest clinical success rates. Laparoscopy-assisted ERCP (LA-ERCP)performed by advancing a standard duodenoscope through a gastrostomy into the excluded stomach and duodenumhas emerged as a viable alternative to BAE-ERCP, with apparently higher success rates. In this systematic review, we compare LA-ERCP with enteroscopy-based techniques in post-RYGB patients, including 22 case series that provided data on papilla identification, papilla cannulation, and complications. We found that LA-ERCP was superior to the enteroscopy-based techniques in its capacity to reach the duodenal papilla, although complication rates were lower for the latter. Comparative studies are needed in order to corroborate our findings.

    Percutaneous endoscopic versus surgical gastrostomy in patients with benign and malignant diseases: a systematic review and meta-analysis
    (2016) BRAVO, Jose Goncalves Pereira; IDE, Edson; KONDO, Andre; MOURA, Diogo Turiani Hourneaux de; MOURA, Eduardo Turiani Hourneaux de; SAKAI, Paulo; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux de
    To compare the complications and mortality related to gastrostomy procedures performed using surgical and percutaneous endoscopic gastrostomy techniques, this review covered seven studies. Five of these were retrospective and two were randomized prospective studies. In total, 406 patients were involved, 232 of whom had undergone percutaneous endoscopic gastrostomy and 174 of whom had undergone surgical gastrostomy. The analysis was performed using Review Manager. Risk differences were computed using a fixed-effects model and forest and funnel plots. Data on risk differences and 95% confidence intervals were obtained using the Mantel-Haenszel test. There was no difference in major complications in retrospective (95% CI (-0.11 to 0.10)) or randomized (95% CI (-0.07 to 0.05)) studies. Regarding minor complications, no difference was found in retrospective studies (95% CI (-00.17 to 0.09)), whereas a difference was observed in randomized studies (95% CI (-0.25 to -0.02)). Separate analyses of retrospective and randomized studies revealed no differences between the methods in relation to mortality and major complications. Moreover, low levels of minor complications were observed among endoscopic procedures in randomized studies, with no difference observed compared with retrospective studies.

    Nonsteroidal anti-inflammatory drugs versus placebo for post-endoscopic retrograde cholangiopancreatography pancreatitis: a systematic review and meta-analysis
    (2019) SERRANO, Juan Pablo Roman; MOURA, Diogoturiani Hourneaux de; BERNARDO, Wanderley Marques; RIBEIRO, Igor Braga; FRANZINI, Tomazo Prince; MOURA, Eduardo Turiani Hourneaux de; BRUNALDI, Vitor Ottoboni; SALESSE, Marianne Torrezan; SAKAI, Paulo; MOURA, Eduardo Guimaraes Hourneaux De
    Background and study aims Endoscopic retrograde cholangiopancreatography (ERCP) is the primary therapeutic procedure for treatment of diseases that affect the biliary tree and pancreatic duct. While the therapeutic success rate of ERCP is high, the procedure can cause complications, such as acute pancreatitis (PEP), bleeding, and perforation. This meta-analysis aimed to assess the efficacy of nonsteroidal anti-inflammatory drugs (NSAIDs) in preventing PEP following (ERCP). Materials and methods We searched databases, such as MEDLINE, Embase, and Cochrane Central Library. Only randomized controlled trials (RCTs) that compared the efficacy of NSAIDs and placebo for the prevention of PEP were included. Outcomes assessed included incidence of PEP, severity of pancreatitis, route of administration, and type of NSAIDs. Results Twenty-one RCTs were considered eligible with a total of 6854 patients analyzed. Overall, 3427 patients used NSAIDs before ERCP and 3427 did not use the drugs (control group). In the end, 250 cases of acute pancreatitis post-ERCP were diagnosed in the NSAIDs group and 407 cases in the placebo group. Risk for PEP was lower in the NSAID group (risk difference (RD): -0.05; 95% confidence interval (CI): -0.07 to -0.03; number need to treat (NNT), 20; P<0.05). Use of NSAIDs effectively prevented mild pancreatitis compared with use of placebo (2.5% vs. 4.1%; 95% CI, -0.05 to -0.01; NNT, 33; P<0.05), but the information on moderate and severe PEP could not be completely elucidated. Only rectal administration reduced incidence of PEP (6.8% vs. 13 %; 95% CI, -0.10 to -0.04; NNT, 20; P<0.05). Furthermore, only diclofenac or indomethacin use was effective in preventing PEP. Conclusions Rectal administration of diclofenac and indomethacin significantly reduced risk of developing mild PEP. Further RCTs are needed to compare efficacy between NSAID administration pathways in prevention of PEP after ERCP.

    Early Endoscopic Retrograde Cholangiopancreatography Versus Conservative Treatment in Patients With Acute Biliary Pancreatitis: Systematic Review and Meta-analysis of Randomized Controlled Trials
    (2018) COUTINHO, Lara M. de A.; BERNARDO, Wanderley M.; ROCHA, Rodrigo S.; MARINHO, Fabio R.; DELGADO, Aureo; MOURA, Eduardo T. H.; MATUGUMA, Sergio E.; CHAVES, Dalton; FRANZINI, Tomazo A. P.; SAKAI, Paulo; MOURA, Eduardo G. H. de
    Objectives The aim of the study was to evaluate the role of early endoscopic retrograde cholangiopancreatography (ERCP) in the treatment of acute biliary pancreatitis, in comparison with conservative treatment. Methods Systematic review via databases (MEDLINE [PubMed], Latin-American and Caribbean Health Sciences Literature database, Embase, Cochrane Central, and the [Brazilian] Regional Library of Medicine) is conducted. We analyzed 10 randomized controlled trials (1091 patients). Outcomes were the following: local and systemic adverse events; acute cholangitis; death; length of hospital stay; cost; abdominal pain; and time to a reduction in body temperature. For the meta-analysis, we used risk difference (RD) and mean with standard deviation as measures of variability. Results There was a statistically significant difference between the patients submitted to ERCP in terms of the following: local adverse events (RD, 0.74; 95% confidence interval [CI], 0.55-0.99), time to pain relief and time to a reduction in axillary temperature (RD, -5.01; 95% CI, -6.98 to -3.04, and RD, -1.70; 95 CI%, -2.33 to -1.08, respectively). Patients undergoing ERCP spent less time in hospital (RD, -11.04; 95% CI, -15.15 to -6.93). Cost was lower in the group treated with ERCP. Conclusions Early ERCP decreases local adverse events, shortening the time to pain relief, to a reduction in axillary temperature, hospital stays, and cost in patients with acute biliary pancreatitis.

    Surveillance in inflammatory bowel disease: is chromoendoscopy the only way to go? A systematic review and meta-analysis of randomized clinical trials
    (2020) RESENDE, Ricardo Hannum; RIBEIRO, Igor Braga; MOURA, Diogo Turiani Hourneaux de; GALETTI, Facundo; ROCHA, Rodrigo Silva de Paula; BERNARDO, Wanderley Marques; SAKAI, Paulo; MOURA, Eduardo Guimaraes Hourneaux de
    Background and study aims Ulcerative colitis (UC) and Crohn's disease (CD) have higher risk of colorectal cancer (CRC). Guidelines recommend dysplasia surveillance with dye-spraying chromoendoscopy (DCE). The aim of this systematic review and meta-analysis was to review all randomized clinical trials (RCTs) available and compare the efficacy of different endoscopic methods of surveillance for dysplasia in patients with UC and CD. Methods Databases searched were Medline, EMBASE, Cochrane and SCIELO/LILACS. It was estimated the risk difference (RD) for dichotomous outcomes (number of patients diagnosed with one or more dysplastic lesions, total number of dysplastic lesions diagnosed and number of dysplastic lesions detected by targeted biopsies) and mean difference for continuous outcomes (procedure time). Results This study included 17 RCTs totaling 2,457 patients. There was superiority of DCE when compared to standard-definiton white light endoscopy (SD-WLE). When compared with high-definition (HD) WLE, no difference was observed in all outcomes (number of patients with dysplasia (RD 0.06; 95 % CI [-0.01, 0.13])). Comparing other techniques, no difference was observed between DCE and virtual chromoendoscopy (VCE - including narrow-band imaging [NBI], i-SCAN and flexible spectral imaging color enhancement), in all outcomes except procedure time (mean difference, 6.33 min; 95 % CI, 1.29, 11.33). DCE required a significantly longer procedure time compared with WLE (mean difference, 7.81 min; 95 % CI, 2.76, 12.86). Conclusions We found that dye-spraying chromoendoscopy detected more patients and dysplastic lesions than SD-WLE. Although no difference was observed between DCE and HD-WLE or narrow-band imaging, the main outcomes favored numerically dye-spraying chromoendoscopy, except procedure time. Regarding i-SCAN, FICE and auto-fluorescence imaging, there is still not enough evidence to support or not their recommendation.

    Risk factors for gastroesophageal reflux after POEM for achalasia: a systematic review and meta-analysis
    (2021) MOTA, Raquel Cristina Lins; MOURA, Eduardo Guimaraes Hourneaux de; MOURA, Diogo Turiani Hourneaux de; BERNARDO, Wanderlei Marques; MOURA, Eduardo Turiani Hourneaux de; BRUNALDI, Vitor O.; SAKAI, Paulo; THOMPSON, Christopher C.
    Introduction Peroral endoscopic myotomy (POEM) demonstrated similar efficacy to surgical myotomy in the management of achalasia. However, gastroesophageal reflux disease (GERD) is common after POEM. The aim of this study is to identify factors associated with GERD after POEM. Method After searching electronic databases, randomized trials and observational studies including patients with achalasia or other spastic esophageal disorders, treated by POEM, and providing GERD data were selected. GERD was evaluated by 3 methods: pH monitoring, endoscopic findings, and symptoms. For each method, an analysis was performed comparing the outcomes related to the following independent variables: full-thickness (FT) vs circular myotomy, anterior vs posterior, long myotomy vs short myotomy, naive vs previous treatment failure, previous Heller myotomy (HM) vs non-previous-HM, Type I vs II, Type I vs III, and Type II vs III. Results 2869 publications were identified, and 25 studies met criteria for inclusion in the qualitative analysis. Of these, 18 were included in the meta-analysis. According to the endoscopic findings, circular and anterior myotomy demonstrated a lower trend of GERD with borderline significance (p = 0.06; p = 0.07, respectively). In the pH monitoring and symptom analyses, circular myotomy, anterior myotomy, treatment naive, and non-HM patients were associated with a lower occurrence of GERD; however, no statistically significant difference was found. When comparing achalasia subtypes, no statistical difference was found in all analyses. Conclusion This systematic review and meta-analysis suggest that a circular anterior approach may limit post-POEM GERD and should be considered in appropriate patients.

    Systematic review and meta-analysis of colon capsule endoscopy accuracy for colorectal cancer screening. An alternative during the Covid-19 pandemic?
    (2022) SULBARAN, Marianny; BUSTAMANTE-LOPEZ, Leonardo; BERNARDO, Wanderley; SAKAI, Christiano M.; SAKAI, Paulo; NAHAS, Sergio; MOURA, Eduardo G. H. de
    Aim To determine the diagnostic accuracy of colon capsule endoscopy for colorectal cancer screening. Methods Studies that compared the diagnostic performance of colonoscopy and second-generation colon capsule endoscopy (CCE-2) for screening of asymptomatic patients aged 50-75 years were included. The primary outcomes were sensitivity, specificity, and positive and negative likelihood ratios for polyps and adenomas measuring at least 6 mm or 10 mm. Results Eight full-text studies that evaluated 1602 patients were included for systematic review. Of these, 840 (52.43%) patients participated in an opportunistic screening program. The pooled outcomes of CCE-2 for polyps at least 6 mm / 10 mm were (CI = confidence interval): sensitivity: 88% (95% CI: 0.84-0.91) / 88% (95% CI: 0.82-0.93), specificity: 94% (95% CI: 0.92-0.95) / 95.5% (95% CI: 0.94-0.97); positive likelihood ratio: 11.86 (95% CI: 5.53-25.46) / 23.07 (95% CI: 6.163-86.36); negative likelihood ratio: 0.14 (95% CI: 0.1-0.21) / 0.14 (95% CI: 0.09-0.21). The area under the summary receiver operating characteristic curve for polyps at least 6 and 10 mm was 96.3% and 96.7%, respectively. The only cancer missed by complete CCE-2 was shown at multiple frames in the unblinded review. In total, 125 (7.8%) patients presented mild adverse events mostly related to bowel preparation. Conclusion CCE-2 is demonstrated to be an effective and safe alternative method for colorectal cancer screening. Diagnostic performance of CCE-2 for polyps of at least 6 and 10 mm was similar. Completion rates still need to be improved.
