    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 de
    Background 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.

    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 de
    The 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.

    Endoscopic Treatment of Weight Regain Following Roux-en-Y Gastric Bypass: a Systematic Review and Meta-analysis
    (2018) BRUNALDI, Vitor Ottoboni; JIRAPINYO, Pichamol; MOURA, Diogo Turiani H. de; OKAZAKI, Ossamu; BERNARDO, Wanderley M.; GALVO NETO, Manoel; CAMPOS, Josemberg Marins; SANTO, Marco Aurelio; MOURA, Eduardo G. H. de
    Roux-en-Y gastric bypass (RYGB) is the most commonly performed bariatric procedure. Despite its high efficacy, some patients regain part of their lost weight. Several endoscopic therapies have been introduced as alternatives to treat weight regain, but most of the articles are relatively small with unclear long-term data. To systematically assess the efficacy of endoscopic therapies for weight regain after RYGB. We searched MEDLINE, EMBASE, Scopus, Web of Science, Cochrane, OVID, CINAHL/EBSCo, LILACS/Bireme, and gray literature. Primary outcomes were absolute weight loss (AWL), excess weight loss (EWL), and total body weight loss (TBWL). Thirty-two studies were included in qualitative analysis. Twenty-six described full-thickness (FT) endoscopic suturing and pooled AWL, EWL, and TBWL at 3 months were 8.5 +/- 2.9 kg, 21.6 +/- 9.3%, and 7.3 +/- 2.6%, respectively. At 6 months, they were 8.6 +/- 3.5 kg, 23.7 +/- 12.3%, and 8.0 +/- 3.9%, respectively. At 12 months, they were 7.63 +/- 4.3 kg, 16.9 +/- 11.1%, and 6.6 +/- 5.0%, respectively. Subgroup analysis showed that all outcomes were significantly higher in the group with FT suturing combined with argon plasma coagulation (APC) (p < 0.0001). Meta-analysis included 15 FT studies and showed greater results. Three studies described superficial-thickness suturing with pooled AWL of 3.0 +/- 3.8, 4.4 +/- 0.07, and 3.7 +/- 7.4 kg at 3, 6, and 12 months, respectively. Two articles described APC alone with mean AWL of 15.4 +/- 2.0 and 15.4 +/- 9.1 kg at 3 and 6 months, respectively. Full-thickness suturing is effective at treating weight regain after RYGB. Performing APC prior to suturing seems to result in greater weight loss. Head-to-head studies are needed to confirm our results. Few studies adequately assess effectiveness of other endoscopic techniques.

    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 De
    Background 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.

    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.

    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 de
    Introduction: 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.

    Endoscopic ultrasound-guided vs endoscopic retrograde cholangiopancreatography biliary drainage for obstructed distal malignant biliary strictures: A systematic review and meta-analysis
    (2019) LOGIUDICE, Fernanda P.; BERNARDO, Wanderlei M.; GALETTI, Facundo; SAGAE, Vitor M.; MATSUBAYASHI, Carolina O.; MADRUGA NETO, Antonio C.; BRUNALDI, Vitor O.; MOURA, Diogo T. H. de; FRANZINI, Tomazo; CHENG, Spencer; MATUGUMA, Sergio E.; MOURA, Eduardo G. H. de
    BACKGROUND For palliation of malignant biliary obstruction (MBO), the gold-standard method of biliary drainage is endoscopic retrograde cholangiopancreatography (ERCP) with the placement of metallic stents. Endoscopic ultrasound (EUS)-guided drainage is an alternative that is typically reserved for cases of ERCP failure. Recently, however, there have been robust randomized clinical trials (RCTs) comparing EUS-guided drainage and ERCP as primary approaches to MBO. AIM To compare EUS guidance and ERCP in terms of their effectiveness and safety in palliative biliary drainage for MBO. METHODS This was a systematic review and meta-analysis, in which we searched the MEDLINE, Excerpta Medica, and Cochrane Central Register of Controlled Trials databases. Only RCTs comparing EUS and ERCP for primary drainage of MBO were eligible. All of the studies selected provided data regarding the rates of technical and clinical success, as well as the duration of the procedure, adverse events, and stent patency. We assessed the risk of biases using the Jadad score and the quality of evidence using the Grading of Recommendations Assessment, Development and Evaluation criteria. RESULTS The database searches yielded 5920 records, from which we selected 3 RCTs involving a total of 222 patients (112 submitted to EUS and 110 submitted to ERCP). In the EUS and ERCP groups, the rate of technical success was 91.96% and 91.81%, respectively, with a risk difference (RD) of 0.00% (95% CI: -0.07, 0.07; P = 0.97; I-2 = 0%). The clinical success was 84.81% and 85.53% in the EUS and ERCP groups, respectively, with an RD of -0.01% (95% CI: -0.12, 0.10; P = 0.90; I-2 = 0%). The mean difference (MD) for the duration of the procedure was -0.12% (95% CI: -8.20, 7.97; P = 0.98; I-2 = 84%). In the EUS and ERCP groups, there were 14 and 25 adverse events, respectively, with an RD of -0.06% (95% CI: -0.23, 0.12; P = 0.54; I-2 = 77%). The MD for stent patency was 9.32% (95% CI: -4.53, 23.18; P = 0.19; I-2 = 44%). The stent dysfunction rate was significantly lower in the EUS group (MD = -0.22%; 95CI:-0.35, -0.08; P = 0.001; I-2 = 0%). CONCLUSION EUS represents an interesting alternative to ERCP for MBO drainage, demonstrating lower stent dysfunction rates compared with ERCP. Technical and clinical success, duration, adverse events and patency rates were similar.
