- Is Endoscopic Balloon Dilation Still Associated With Higher Rates of Pancreatitis? A Systematic Review and Meta-Analysis(2020) MATSUBAYASHI, Carolina Ogawa; RIBEIRO, Igor Braga; MOURA, Diogo Turiani Hourneaux de; BRUNALDI, Vitor Ottoboni; BERNARDO, Wanderley Marques; HATHORN, Kelly E.; MOURA, Eduardo Guimaraes Hourneaux deThe objective of this study was to compare the efficacy and safety of endoscopic papillary balloon dilation (EPBD), endoscopic sphincterotomy (ES), and the combination of large balloon dilation and ES (ES + EPLBD) in the treatment of common bile duct stones, with a special focus on postendoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). Individualized search strategies were developed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We included randomized controlled trials (RCTs) which evaluated at least one of the following outcomes: PEP, complete stone removal in the first ERCP, need for mechanical lithotripsy, recurrence of common bile duct stones, bleeding, and cholangitis. Twenty-five RCTs were selected for analysis. Pancreatitis rates were higher for EPBD than for ES (P = 0.003), as were severe pancreatitis rates (P = 0.04). However, in the 10-mm or greater balloon subgroup analysis, this difference was not shown (P = 0.82). Rates of PEP were higher in the subgroup of non-Asian subjects (P = 0.02), and the results were not robust when RCTs that used endoscopic nasobiliary drainage were omitted. The incidence of pancreatitis was comparable between EPLBD and ES + EPLBD. All 3 approaches were equally efficacious. Nevertheless, the results should be interpreted with caution, because pancreatitis is a multifactorial pathology, and RCTs can have limited generalizability.
- EUS-Guided Intragastric Injection of Botulinum Toxin A in the Preoperative Treatment of Super-Obese Patients: a Randomized Clinical Trial(2019) MOURA, Eduardo Guimaraes Hourneaux de; RIBEIRO, Igor Braga; FRAZAO, Mariana Souza Varela; MESTIERI, Luiz Henrique Mazzonetto; MOURA, Diogo Turiani Hourneaux de; BO, Creusa Maria Roveri Dal; BRUNALDI, Vitor Ottoboni; MOURA, Eduardo Turiani Hourneaux de; NUNES, Gabriel Cairo; BUSTAMANTE, Fabio Alberto Castillo; GALVAO NETO, Manoel dos Passos; MATUGUMA, Sergio Eiji; BERNARDO, Wanderley Marques; SANTO, Marco AurelioBackgroundObesity is a disease that is highly prevalent in Brazil, and the associated comorbidities represent a major global public health challenge. Botulinum toxin type A (BTX-A) is a potent neurotoxin and inhibitor of gastric smooth muscle activity. In theory, BTX-A administration should promote early satiety and weight loss because it delays gastric emptying by inhibiting acetylcholine-mediated peristalsis, which is primarily responsible for gastric motility. Because results in the literature are discrepant, the efficacy of intragastric injections of BTX-A as a primary treatment for obesity remains unknown. The objective of this prospective, double-blind, single-center randomized study was to evaluate the effects of endoscopic ultrasound-guided intragastric BTX-A injections, as a bridge to bariatric surgery, in super-obese patients.MethodsThirty-two super-obese patients were randomized to one of two groups: BTX-A, in which 200units of BTX-A were injected into the gastric antrum and body; and control, in which the same injections were performed with 0.9% saline. Weight, body mass index (BMI), and loss of excess weight were measured monthly over a 6-month period. Gastric emptying scintigraphy was performed before and after the procedure.ResultsThe patients in both groups showed significant weight loss over the course of the study (p<0.001). There were no statistically significant differences between the groups regarding weight loss, excess weight, total loss of excess weight, total weight loss, or change in BMI.ConclusionsIntragastric injection of BTX-A does not appear to be an effective method of achieving preoperative weight loss in super-obese patients.
bookPart O Papel da Endoscopia no Sobrepeso e na Obesidade: Toxina Botulínica(2017) BUSTAMANTE, Fábio Alberto Castillo; BRUNALDI, Vitor Ottoboni; MOURA, Diogo Turiani Hourneaux de; SOUZA, Thiago Ferreira de; MOURA, Eduardo Guimarães Hourneaux de- 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.
- Randomized controlled trial of hemostatic powder versus endoscopic clipping for non-variceal upper gastrointestinal bleeding(2020) BARACAT, Felipe Iankelevich; MOURA, Diogo Turiani Hourneaux de; BRUNALDI, Vitor Ottoboni; TRANQUILLINI, Caio Vinicius; BARACAT, Renato; SAKAI, Paulo; MOURA, Eduardo Guimaraes Hourneaux deBackground and aims Despite advances in pharmacological and endoscopic management of non-variceal upper gastrointestinal bleeding (NVUGIB), mortality is still relevant. TC-325 (Hemospray-Cook Medical) is a mineral powder with adsorptive properties, designed for endoscopic hemostasis. There are still no comparative trials studying this new hemostatic modality. The objective of this research was to compare the use of TC-325 (associated with epinephrine injection) with the combined technique of endoscopic clipping and epinephrine injection for the treatment of patients with NVUGIB. Methods We conducted a pilot randomized controlled trial with patients that presented NVUGIB with an actively bleeding lesion at the endoscopic evaluation. Patients were randomized either to the Hemospray or Hemoclip group. The randomization list was generated by a computer program and remained unknown throughout the entire trial. All patients underwent second-look endoscopy. Results Thirty-nine patients were enrolled. Peptic ulcer was the most frequent etiology. Primary hemostasis was achieved in all Hemospray cases and in 90% of Hemoclip group (p = 0.487). Five patients in Hemospray group underwent an additional hemostatic procedure during second-look endoscopy, while no patient in the Hemoclip group needed it (p = 0.04). Rebleeding, emergency surgery and mortality rates were similar in both groups. No toxicity, allergy events, or gastrointestinal obstruction signs were observed in Hemospray group. Conclusions TC-325 presents similar hemostatic results when compared with conventional dual therapy for patients with NVUGIB. Hemospray's excellent primary hemostasis rate certifies it as a valuable tool in arduous situations of severe bleeding or difficult location site.
- Argon plasma coatmlation alone versus argon plasma coagulation plus full-thickness endoscopic suturing to treat weight regain after Roux-en-Y gastric bypass: a prospective randomized trial (with videos)(2020) BRUNALDI, Vitor Ottoboni; FARIAS, Galileu Ferreira Ayala; REZENDE, Daniel Tavares de; CAIRO-NUNES, Gabriel; RICCIOPPO, Daniel; MOURA, Diogo Turiani Hourneaux de; SANTO, Marco Aurelio; MOURA, Eduardo Guimaraes Hourneaux deBackground and Aims: A significant number of patients regain weight after Roux-en-Y gastric bypass. Ablation with argon plasma coagulation (APC) plus endoscopic full-thickness suturing (FTS-APC) and ablation alone have been reported for treating weight regain when associated with gastrojejunostomy (GJ) dilation. However, comparative controlled data are still lacking. Methods: This was a pilot single-center open-label randomized trial comparing the effectiveness and safety of APC alone versus FTS-APC for transoral outlet reduction. Patients with at least 20% weight regain from the nadir, and GJ >= 15 mm were considered eligible. The primary outcome was percentage total weight loss (%TWL) at 12 months. Secondary outcomes were the incidence of adverse events, amelioration of metabolic laboratory parameters, and improvement in quality of life and eating behavior. Results: Forty patients meeting the eligibility criteria were enrolled from October 2017 to July 2018. Technical and clinical success rates were similar between the groups. At 12 months, the mean %TWL was 8.3% +/- 5.5% in the APC alone group versus 7.5% +/- 7.7% in the Fl S-APC group (P = .71). The pre-revisional % solid gastric retention at 1 hour positively correlated with the probability of achieving >= 10% TWL at 12 months. Both groups experienced significant reductions in low-density lipoprotein and triglyceride levels at 12 months, and improvement in eating behavior and quality of life at 3 months. There were 2 cases of stenoses (1 from each group), which were successfully treated with endoscopic balloon dilation. Conclusion: APC alone is similar to FTS-APC in terms of technical and clinical outcomes within 1 year of followup.
bookPart Reganho de Peso(2017) BRUNALDI, Vitor Ottoboni; MOURA, Diogo Turiani Hourneaux de; SAKAI, Christiano Makoto; MOURA, Eduardo Guimarães Hourneaux de- The Effectiveness of Endoscopic Gastroplasty for Obesity Treatment According to FDA Thresholds: Systematic Review and Meta-Analysis Based on Randomized Controlled Trials(2018) MADRUGA-NETO, Antonio Coutinho; BERNARDO, Wanderley Marques; MOURA, Diogo Turiani Hourneaux de; BRUNALDI, Vitor Ottoboni; MARTINS, Rafael Krieger; JOSINO, Iatagan Rocha; MOURA, Eduardo Turiani Hourneaux de; SOUZA, Thiago Ferreira de; SANTO, Marco Aurelio; MOURA, Eduardo Guimares Hourneaux deEndoscopic bariatric therapies (EBTs) are promising alternatives to conventional surgery for obesity. The aim of this study is to compare efficacy and safety through a systematic review and meta-analysis of the endoscopic gastroplasty techniques versus conservative treatment. We searched MEDLINE, EMBASE, Cochrane CENTRAL, Lilacs/Bireme. Randomized controlled trials (RCTs) enrolling obese patients comparing endoscopic gastroplasty to sham or diet/exercise were considered eligible. Among 6014 records, three RCTs were selected for meta-analysis. The total sample was 459 patients (312 EBTs vs 147 control). Mean total body weight loss in the intervention group (IG) was 4.8% higher than the control group (CG) at 12 months (p = 0.01). The IG responder rate was 44.31% at 12 months. Therefore, the endoscopic gastroplasty is more effective than conservative therapies but do not achieve FDA thresholds.
- 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 deBackground 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 deIntroduction: 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.
