- 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, PauloBackground 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.
- Long-term follow-up after transoral outlet reduction following Roux-en-Y gastric bypass: Back to stage 0?(2023) BRUNALDI, Vitor Ottoboni; OLIVEIRA, Guilherme Henrique Peixoto de; KERBAGE, Anthony; RIBAS, Pedro Henrique; NUNES, Felipe; FARIA, Galileu; MOURA, Diogo de; RICCIOPPO, Daniel; SANTO, Marco; MOURA, Eduardo deBackground and study aims Significant weight regain affects up to one-third of patients after Roux-en-Y gastric bypass (RYGB) and demands treatment. Transoral outlet reduction (TORe) with argon plasma coagulation (APC) alone or APC plus full-thickness suturing TORe (APC-FTS) is effective in the short term. However, no study has investigated the course of gastrojejunostomy (GJ) or quality of life (QOL) data after the first post-procedure year.Patients and methods Patients eligible for a 36-month follow-up visit after TORe underwent upper gastrointestinal endoscopy with measurement of the GJ and answered QOL questionnaires (RAND-36). The primary aim was to evaluate the long-term outcomes of TORe, including weight loss, QOL, and GJ anastomosis (GJA) size. Comparisons between APC and APC-FTS TORe were a secondary aim.Results Among 39 eligible patients, 29 returned for the 3-year follow-up visit. There were no significant differences in demographics between APC and APC-FTS TORe groups. At 3 years, patients from both groups regained all the weight lost at 12 months, and the GJ diameter was similar to the pre-procedure assessment. As to QOL, most improvements seen at 12 months were lost at 3 years, returning to pre-procedure levels. Only the energy/fatigue domain improvement was kept between the 1- and 3-year visits.Conclusions Obesity is a chronic relapsing disease. Most effects of TORe are lost at 3 years, and redilation of the GJA occurs. Therefore, TORe should be considered iterative rather than a one-off procedure.
- 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, JoseBackground 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.
- A rare non-oncological pancreatic mass: eosinophilic pancreatitis diagnosis through EUS-FNA(2019) MOURA, Diogo Turiani Hourneaux De; ROCHA, Rodrigo Silva de Paula; JUKEMURA, Jose; BRUNALDI, Vitor Ottoboni; GUEDES, Hugo Goncalo; TORREZ, Franz Robert Apodaca; RIBEIRO, Igor Braga; GELRUD, Andres; MOURA, Eduardo Guimaraes Hourneaux DeBackground and study aims Eosinophilic pancreatitis (EP) is a rare etiology of chronic pancreatitis, and few cases have been reported. It is characterized by eosinophilic infiltration of the pancreas and elevated IgE levels. EP is difficult to distinguish from pancreatic cancer based on clinical symptoms and auxiliary exams. We present a case of EP and debate the routine performance of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for resectable pancreatic mass.
- 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 DeBackground 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.
- Anti-reflux versus conventional self-expanding metal stents in the palliation of esophageal cancer: A systematic review and meta-analysis(2022) SASSO, Joao Guilherme Ribeiro Jordao; MOURA, Diogo Turiani Hourneaux de; PROENCA, Igor Mendonca; MONTE JUNIOR, Epifanio Silvino do; RIBEIRO, Igor Braga; SANCHEZ-LUNA, Sergio A.; CHENG, Spencer; BESTETTI, Alexandre Moraes; KUM, Angelo So Taa; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux deBackground and study aims Self-expanding metal stents (SEMS) are an effective palliative endoscopic therapy to reduce dysphagia in esophageal cancer. Gastroesophageal reflux disease (GERD) is a relatively common complaint after non-valved conventional SEMS placement. Therefore, valved self-expanding metal stents (SEMS-V) were designed to reduce the rate of GERD symptoms. We aimed to perform a systematic review and meta-analysis comparing the two stents. Material and methods This was a systematic review and meta-analysis including only randomized clinical trials (RCT) comparing the outcomes between SEMS-V and non-valved self-expanding metal stents (SEMS-NV) following the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. The risk of bias was assessed using the Cochrane Risk of Bias 2 tool. Data were analyzed with Review Manager Software. Quality of evidence was evaluated using Grading of Recommendations Assessment, Development, and Evaluation guidelines. Results Ten randomized clinical trials including a total of 467 patients, 234 in the SEMS-V group and 233 in the SEMS-NV group, were included. There were no statistically significant differences regarding GERD qualitative analysis (RD -0.17; 95% CI -0.67, 0.33; P= 0.5) and quantitative analysis (SMD -0.22; 95% CI -0.53, 0.08; P=0.15) technical success (RD -0.03; 95% CI -0.07, 0.01; P= 0.16), dysphagia improvement (RD -0.07; 95% CI -0.19, 0.06; P=0.30), and adverse events (RD 0.07; 95% CI -0.07, 0.20; P= 0.32). Conclusions Both SEMS-V and SEMS-NV are safe and effective in the palliation of esophageal cancer with similar rates of GERD, dysphagia relief, technical success, adverse events, stent migration, stent obstruction, bleeding, and improvement of the quality of life.
- Peroral endoscopic myotomy (POEM): a comparative study between Chagasic and idiopathic achalasia(2020) FARIAS, Galileu F. A.; MOURA, Diogo T. H. de; MOURA, Eduardo T. H. de; REZENDE, Daniel T. de; HATHORN, Kelly E.; NASI, Ary; QUEIROZ, Natalia S. F.; MOURA, Eduardo G. H. deBackground and study aims Achalasia can be classified as either primary (idiopathic) achalasia or secondary achalasia, which is a consequence of another systemic disease. Peroral endoscopic myotomy (POEM) is an effective and safe treatment for achalasia. We evaluated the efficacy and safety of POEM in patients with Chagasic achalasia compared to idiopathic achalasia. Patients and methods We evaluated POEM procedures performed at a single institution from November 2016 to January 2018. Demographic data, Eckardt score, lower esophageal sphincter (LES) pressure, body mass index, post-operative erosive esophagitis, adverse events, length of hospital stay, and procedure-related parameters were analyzed. Results Fifty-one patients underwent POEM as a treatment for achalasia in this period (20 patients with Chagasic and 31 with Idiopathic etiology). The overall clinical success rate was 92.1 %, with no statistical difference between groups (90 % in the Chagasic group vs. 93.5 % in the Idiopathic group, P = 0.640). Both groups had significant reduction in Eckardt score and in LES pressure, and increase in bodey mass index (BMI) at 1-year follow-up. There was no statistical difference between groups regarding Eckardt score ( P = 0.439), LES pressure (p = 0.507), BMI ( P = 0.254), post erosive esophagitis (35 % vs. 38.7 %, P = 0.789), adverse events (30 % vs. 12 %, P = 0.163,) length of hospital stay (3.75 days vs. 3.58 days, P = 0.622), and operative time (101.3 min vs. 99.1 min, P = 0.840). Conclusion POEM is an effective and safe treatment for patients with achalasia. There is no difference in POEM outcomes for those patients with Chagasic or Idiopathic achalasia.
- 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 deBackground 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.
- Primary adenocarcinoma arising in esophageal colon interposition for corrosive esophageal injury: a case report and review of the literature(2018) MOURA, Diogo Turiani Hourneaux De; RIBEIRO, Igor Braga; CORONEL, Martin; MOURA, Eduardo Turiani Hourneaux De; CARVALHO, Joana Rita; BABA, Elisa Ryoka; MOURA, Eduardo Guimaraes Hourneaux DeBackground and study aims Colon interposition for benign strictures is associated with significant perioperative complications that carry high morbidity and mortality. Although rarely reported in the literature, adenocarcinoma can occur as a late complication in an interposed colonic segment. We report a case of a late-stage adenocarcinoma in a colonic interposition performed for benign esophageal stricture.
- 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 deObjectives 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.
