    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.

    Endoscopic polymer injection and endoluminal plication in treatment of gastroesophageal reflux disease: evaluation of long-term results
    (2018) MOURA, Eduardo Guimaraes Hourneaux De; SAIIUM, Rubens A. A.; NASI, Ary; CORONEL, Martin; MOURA, Diogo Turiani Hourneaux De; MOURA, Eduardo Turiani Hourneaux De; MINATA, Mauricio Kazuyoshi; CURY, Marcelo; FALCAO, Angela; CECCONELLO, Ivan; SAKAI, Paulo
    Background and study aims Us of proton pump inhibitors (PPIs) has made endoscopic treatment of gastroesophageal reflux disease (GERD) more efficient, with reduction in morbidity and complications. However, some patients persist with symptoms despite medical treatment and some are not compliant with it or cannot afford it for financial reasons, and thus they require non-pharmacological therapeutic options such as surgical fundoplication. Surgery may be effective in the short term, but there is related morbidity and concern about its long-term efficacy. The possibility of minimally invasive endoluminal surgeries has resulted in interest in and development of newly endoscopic devices. Good short-term results with surgical fundoplication lack of studies of is with long follow-up justify our interest in this study. The aim of this study was to investigate the efficacy of endoscopic polymer injection and endoluminal full-thickness plication in the long-term control of GERD. Patients and methods Forty-seven patients with GERD who underwent an endoscopic procedure were followed up for 60 months and evaluated for total response (RT), partial response (RP) and no response (SR) to endoscopic treatment with reintroduction of PPIs. Results Twenty-one patients received polymer injection (G0) and 26 endoluminal plication (G1). The number of patients with no response to endoscopic treatment with reintroduction of PPIs increased in time for both techniques (G0 P = 0.006; G1 P < 0.001). There was symptomatic improvement up to 12 months, with progressive loss of this trending up to 60 months in G0 and G1 (P < 0.001). Health-related quality of life score (GERD-HRQL) demonstrated TR in G0 and G1 at 1, 3, 6 and 12 months. The 60-month analysis showed an increased number of patients with SR in both groups. The quality of life assessment (SF-36) showed benefit in G0 up to 3 months. G0 showed a higher rate of complications. There were no deaths. There was healing of esophagitis at 3 months in 45 % of patients in G0 and 40 % in G1. There was no improvement in manometric or pH findings. Conclusion Endoscopic therapies were ineffective in controlling GERD in the long term.

    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.

    Sodium picosulphate or polyethylene glycol before elective colonoscopy in outpatients? A systematic review and meta-analysis
    (2018) ROCHA, Rodrigo Silva de Paula; RIBEIRO, Igor Braga; MOURA, Diogo Turiani Hourneaux de; BERNARDO, Wanderley Marques; MINATA, Mauricio Kazuyoshi; MORITA, Flavio Hiroshi Ananias; AQUINO, Julio Cesar Martins; BABA, Elisa Ryoka; MIYAJIMA, Nelson Tomio; MOURA, Eduardo Guimaraes Hourneaux de
    AIM To determine the best option for bowel preparation [sodium picosulphate or polyethylene glycol (PEG)] for elective colonoscopy in adult outpatients. METHODS A systematic review of the literature following the PRISMA guidelines was performed using Medline, Scopus, EMBASE, Central, Cinahl and Lilacs. No restrictions were placed for country, year of publication or language. The last search in the literature was performed on November 20th, 2017. Only randomized clinical trials with full texts published were included. The subjects included were adult outpatients who underwent bowel cleansing for elective colonoscopy. The included studies compared sodium picosulphate with magnesium citrate (SPMC) and PEG for bowel preparation. Exclusion criteria were the inclusion of inpatients or groups with specific conditions, failure to mention patient status (outpatient or inpatient) or dietary restrictions, and permission to have unrestricted diet on the day prior to the exam. Primary outcomes were bowel cleaning success and/or tolerability of colon preparation. Secondary outcomes were adverse events, polyp and adenoma detection rates. Data on intention-totreat were extracted by two independent authors and risk of bias assessed through the Jadad scale. Funnel plots, Egger's test, Higgins' test (I2) and sensitivity analyses were used to assess reporting bias and heterogeneity. The meta-analysis was performed by computing risk difference (RD) using Mantel-Haenszel (MH) method with fixed-effects (FE) and random-effects (RE) models. Review Manager 5 (RevMan 5) version 6.1 (The Cochrane Collaboration) was the software chosen to perform the meta-analysis. RESULTS 662 records were identified but only 16 trials with 6200 subjects were included for the meta-analysis. High heterogeneity among studies was found and sensitivity analysis was needed and performed to interpret data. In the pooled analysis, SPMC was better for bowel cleaning [MH FE, RD 0.03, IC (0.01, 0.05), P = 0.003, I-2 = 33%, NNT 34], for tolerability [MH RE, RD 0.08, IC (0.03, 0.13), P = 0.002, I-2 = 88%, NNT 13] and for adverse events [MH RE, RD 0.13, IC (0.05, 0.22), P = 0.002, I-2 = 88%, NNT 7]. There was no difference in regard to polyp and adenoma detection rates. Additional analyses were made by subgroups (type of regimen, volume of PEG solution and dietary recommendations). SPMC demonstrated better tolerability levels when compared to PEG in the following subgroups: ""day-before preparation"" [MH FE, RD 0.17, IC (0.13, 0.21), P < 0.0001, I-2 = 0%, NNT 6], "" preparation in accordance with time interval for colonoscopy"" [MH RE, RD 0.08, IC (0.01, 0.15), P = 0.02, I-2 = 54%, NNT 13], when compared to ""high-volume PEG solutions"" [MH RE, RD 0.08, IC (0.01, 0.14), I-2 = 89%, P = 0.02, NNT 13] and in the subgroup "" liquid diet on day before"" [MH RE, RD 0.14, IC (0.06,0.22), P = 0.0006, I-2 = 81%, NNT 8]. SPMC was also found to cause fewer adverse events than PEG in the "" high-volume PEG solutions"" [MH RE, RD -0.18, IC (-0.30, -0.07), P = 0.002, I-2 = 79%, NNT 6] and PEG in the "" low-residue diet"" subgroup [MH RE, RD -0.17, IC (-0.27, 0.07), P = 0.0008, I-2 = 86%, NNT 6]. CONCLUSION SPMC seems to be better than PEG for bowel preparation, with a similar bowel cleaning success rate, better tolerability and lower prevalence of adverse events.

    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.

    Laparoscopic Greater Curvature Plication and Laparoscopic Sleeve Gastrectomy Treatments for Obesity: Systematic Review and Meta-Analysis of Short- and Mid-Term Results
    (2018) BARRICHELLO, Sergio; MINATA, Mauricio Kazuyoshi; GORDEJUELA, Amador Garcia Ruiz de; BERNARDO, Wanderley Marques; SOUZA, Thiago Ferreira de; GALVO NETO, Manoel; MOURA, Diogo Turiani Hourneaux de; SANTO, Marco Aurelio; MOURA, Eduardo Guimares Hourneaux de
    Laparoscopic greater curvature plication (LGP) has recently emerged as a new bariatric procedure. This surgery provides gastric restriction without resection, which could potentially provide a lower risk alternative, with fewer complications. The real benefit of this technique in the short and long term is unknown. This systematic review aims to compare laparoscopic gastric plication and laparoscopic sleeve gastrectomy for obesity treatment. Clinical trials were identified in MEDLINE, Embase, Cochrane, LILACS, BVS, SCOPUS, and CINAHL databases. Comparison of LGP and laparoscopic sleeve gastrectomy (SG) included hospital stay, operative time, loss of hunger feeling, body mass index loss (BMIL), percentage of excess weight loss (%EWL), complications, symptoms in the postoperative period, and comorbidity remission or improvement. This systematic review search included 17,423 records. Eight studies were selected for meta-analysis. There is no difference in operative time, hospital stay, and complications. Patients in the SG group had improved loss of hunger feeling. BMIL was better in the SG group at 12 and 24 months [mean difference (MD) - 2.19, 95% confidence interval (CI) - 3.10 to - 1.28, and MD - 4.59, 95% CI - 5.55 to - 3.63, respectively]. SG showed improved %EWL compared with gastric plication in 3, 6, 12, and 24 months. However, no difference was found in %EWL long-term results (24 and 36 months). Patients who underwent LGP had more sialorrhea. SG showed better results in diabetes remission. SG showed improved weight loss when compared with LGP, with better satiety, fewer symptoms in the postoperative period, and improved diabetes remission.

    Carbon dioxide versus air insufflation enteroscopy: a systematic review and meta-analysis based on randomized controlled trials
    (2018) AQUINO, Julio Cesar Martins; BERNARDO, Wanderley Marques; MOURA, Diogo Turiani Hourneaux de; MORITA, Flavio Hiroshi Ananias; ROCHA, Rodrigo Silva de Paula; MINATA, Mauricio Kazuyoshi; CORONEL, Martin; RODELA, Gustavo Luis da Silva; ISHIDA, Robson Kiyoshi; KUGA, Rogerio; MOURA, Eduardo Guimaraes Hourneaux de
    Objectives To compare the insufflation of CO2 and ambient air in enteroscopy. Search sources The investigators researched the electronic databases MedLine, Cochrane Library, Central, LILACS, BVS, Scopus and Cinahl. The grey search was conducted in the base of theses of the University of Sao Paulo, books of digestive endoscopy and references of selected articles and in previous systematic revisions. Study eligibility criteria The evaluation of eligibility was performed independently, in a non-blind manner, by two reviewers, firstly by title and abstract, followed by complete text. Disagreements between the reviewers were resolved by consensus. Data collection and analysis method Through the spreadsheet of data extraction, where one author extracted the data and a second author checked the extraction. Disagreements were resolved by debate between the two reviewers. The quality analysis of the studies was performed using the Jadad score. The software RevMan 5 version 5.3 was used for the meta-analysis. Results Four randomized clinical trials were identified, totaling 473 patients submitted to enteroscopy and comparing insufflation of CO2 and ambient air. There was no statistical difference in the intubation depth between the two groups. When CO2 insufflation was reduced, there was a significant difference in pain levels 1 hour after the procedure (95% IC, -2.49 [-4.72, -0.26], P: 0.03, I-2: 20%) and 3 hours after the procedure (95% IC, -3.05 [-5.92, -0.18], P: 0.04, I-2: 0 %). There was a usage of lower propofol dosage in the CO2 insufflation group, with significant difference (95% IC, -67.68 [-115.53, -19.84], P: 0.006, I-2: 0%). There was no significant difference between the groups in relation to the use of pethidine and to the oxygen saturation. Limitations Restricted number of randomized clinical trials and nonuniformity of data were limitations to the analysis of the outcomes. Conclusion The use of CO2 as insufflation gas in enteroscopy reduces the pain levels 1 hour and 3 hours after the procedure, in addition to the reduction of the sedation (propofol) dosage used.

    Exclusively endoscopic approach to treating gastric perforation caused by an intragastric balloon: case series and literature review
    (2018) BARRICHELLO JUNIOR, Sergio Alexandre; RIBEIRO, Igor Braga; FITTIPALDI-FERNANDEZ, Ricardo Jose; HOFF, Ana Carolina; MOURA, Diogo Turiani Hourneaux de; MINATA, Mauricio Kazuyoshi; SOUZA, Thiago Ferreira de; GALVAO NETO, Manoel dos Passos; MOURA, Eduardo Guimaraes Hourneaux de
    Background and study aims Obesity is a serious disease, resulting in significant morbidity and mortality. Intragastric balloons (IGBs) have been in use since the 1980s. After the insertion of an IGB, complications such as migration of the device and even severe gastric perforation can occur, requiring laparoscopic surgery. Here, we report three cases of gastric perforation after IGB insertion. In all three cases, the perforation was successfully repaired through an exclusively endoscopic approach.
