- The Effectiveness and Safety of the Duodenal-Jejunal Bypass Liner (DJBL) for the Management of Obesity and Glycaemic Control: a Systematic Review and Meta-Analysis of Randomized Controlled Trials(2023) YVAMOTO, Erika Yuki; MOURA, Diogo Turiani Hourneaux de; PROENCA, Igor Mendonca; MONTE JUNIOR, Epifanio Silvino do; RIBEIRO, Igor Braga; RIBAS, Pedro Henrique Boraschi Vieira; HEMERLY, Matheus Candido; OLIVEIRA, Victor Lira de; SANCHEZ-LUNA, Sergio A.; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux deIntroduction The duodenal-jejunal bypass liner (DJBL) is a less-invasive treatment of obesity and type 2 diabetes mellitus (T2DM). Methods This is a systematic review and meta-analysis including randomized clinical trials (RCTs) comparing DJBL versus sham or pharmacotherapies aiming to evaluate the effectiveness and safety of DJBL. Results Ten RCTs (681 patients) were included. The DJBL group showed superior excess weight loss (+ 11.4% [+ 7.75 to + 15.03%], p < 0.00001) and higher decrease in HbA1c compared to the control group (- 2.73 +/- 0.5 vs. - 1.73 +/- 0.4, p = 0.0001). Severe adverse events (SAEs) occurred in 19.7%. Conclusion The DJBL did not reach the ASGE/ASMBS thresholds for the treatment of obesity. However, it is important to state that many SAEs were not really severe. Therefore, we believe this therapy plays an important role in the management obesity and T2DM.
- Endoscopic Biliary Darinage (EBD) versus Percutaneous Transhepatic Biliary Drainage (PTBD) for biliary drainage in patients with Perihilar Cholangiocarcinoma (PCCA): A systematic review and meta-analysis(2023) MOLL, Caroline Flaksbaum; MOURA, Diogo Turiani Hourneaux de; RIBEIRO, Igor Braga; PROENCA, Igor Mendoca; MONTE JUNIOR, Epifanio Silvino do; SANCHEZ-LUNA, Sergio A.; MERCHAN, Maria Fernanda Shinin; INTRIAGO, Josselyn Mariana Vera; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux deBiliary drainage for Perihilar Cholangiocarcinoma (PCCA) can be performed either by endoscopic retrograde chol-angiopancreatography or Percutaneous Transhepatic Biliary Drainage (PTBD). To date there is no consensus about which method is preferred. Taking that into account, the aim of this study is to compare Endoscopic Biliary Drainage (EBD) versus percutaneous transhepatic biliary drainage in patients with perihilar cholangiocarcinoma through a systematic review and metanalysis. A comprehensive search of multiple electronic databases was per-formed. Evaluated outcomes included technical success, clinical success, post drainage complications (cholangitis, pancreatitis, bleeding, and major complications), crossover, hospital length stay, and seeding metastases. Data extracted from the studies were used to calculate Mean Differences (MD). Seventeen studies were included, with a total of 2284 patients (EBD = 1239, PTBD = 1045). Considering resectable PCCA, the PTBD group demon-strated lower rates of crossover (RD = 0.29; 95% CI 0.07-0.51; p = 0.009 I2 = 90%), post-drainage complica-tions (RD = 0.20; 95% CI 0.06-0.33; p < 0.0001; I2 = 78%), and post-drainage pancreatitis (RD = 0.10; 95% CI 0.05-0.16; p < 0.0001; I2 = 64%). The EBD group presented reduced length of hospital stay (RD =-2.89; 95% CI-3.35 --2,43;p < 0.00001; I2 = 42%). Considering palliative PCCA, the PTBD group demonstrated a higher clini-cal success (RD =-0.19; 95% CI-0.27 --0.11;p < 0.00001; I2 = 0%) and less post-drainage cholangitis (RD = 0.08; 95% CI 0.01-0.15; p = 0.02; I2 = 48%) when compared to the EBD group. There was no statistical difference between the groups regarding: technical success, post-drainage bleeding, major post-drainage compli-cations, and seeding metastases.
- Endoscopic Treatment of Complex Walled-Off Necrosis in Necrotizing Pancreatitis With Two Simultaneous Lumen-Apposing Metal Stents: A Case Report(2022) SANTOS, Marcos Eduardo Lera dos; PROENCA, Igor Mendonca; SASSO, Joao Guilherme Ribeiro Jordao; OLIVEIRA, Victor Lira de; RIBAS, Pedro Henrique Boraschi Vieira; BESTETTI, Alexandre Moraes; RIBEIRO, Igor Braga; ANNA, Raoni Salomao Sant; OLIVEIRA, Guilherme Henrique Peixoto de; MOURA, Eduardo Guimaraes Hourneaux deOrganized pancreatic and peripancreatic collections are complications of pancreatitis and should be treated when symptomatic or complicated. When feasible, the endoscopic ultrasound approach presents high efficacy and low morbidity and mortality, making it the first likely option. Among the available accessories for endoscopic drainage, the lumen-apposing metal stent can be a better option, with a low migration rate; furthermore, it allows endoscopic necrosectomy. Here, we present the case of complex walled-off necrosis treated with two lumen-apposing metal stents in the same procedure. A 41-year-old male patient with walled-off necrosis presented with delayed gastric emptying and obstruction of the main biliary duct. Magnetic resonance imaging and endoscopic ultrasound revealed two non-communicating collections. We opted for endoscopic ultrasound-guided drainage with the deployment of two simultaneous lumen-apposing metal stents: one transduodenal and the other transgastric, with clinical improvement. After three weeks, endoscopic retrograde cholangiopancreatography showed a biliary fistula communicating with the periduodenal collection, which was treated with a biliary plastic stent. An endoscopic necrosectomy was performed, and the metal stents were removed. Control magnetic resonance imaging demonstrated improvement. The patient was asymptomatic at the six-month follow-up. The treatment of symptomatic complex walled-off necrosis remains a challenge and may require multiple endoscopic approaches; moreover, surgical treatment may be necessary in case of failure. In the present report, we demonstrate that the deployment of two lumen-apposing metal stents in the same procedure is feasible when necessary as it was associated with technical success and short-term clinical success.
- Gastroesophageal Reflux Waning Over Time in Endoscopic Versus Surgical Myotomy for the Treatment of Achalasia: A Systematic Review and Meta-Analysis(2022) KUM, Angelo So Taa; MOURA, Diogo Turiani De; PROENCA, Igor Mendonca; AIKAWA, Masanori; SANCHEZ-LUNA, Sergio A.; RIBEIRO, Igor Braga; SASSO, Joao Guilherme Ribeiro Jordao; BESTETTI, Alexandre Moraes; BERNARDO, Wanderley Marques; MOURA, Eduardo G. Hourneaux dePeroral endoscopic myotomy (POEM) and Heller myotomy with fundoplication (HMF) effectively treat achalasia, an esophageal motor disease. Although a significant number of meta-analyses have compared POEM and HMF, these studies showed discrepant postoperative gastroesophageal reflux disease (GERD) conclusions. This review aimed to objectively compare GERD over time, as well as the efficiency, safety, and adverse events in POEM versus HMF for treating achalasia.We performed a systematic review and meta-analysis by searching Medline, Embase, Cochrane Library, Scopus, and Clinicaltrials.gov. The evaluated outcomes included early (within 12 months) and late (beyond 12 months) endoscopic assessment of GERD using the Lyon Consensus, clinical success, operative duration (OD), length of stay (LOS), and major adverse events (MAE).A total of 29 observational studies and two randomized clinical trials (RCTs) with 13,914 patients were included. GERD was 28% higher among RCTs discussing POEM at early assessment (95%CI 0.02, 0.54) and was not different at late evaluation (95% confidence interval (CI) = 0.00, 0.22). No difference in reflux was observed among observational studies in both periods. The clinical success was 9% higher (95% CI = 0.05, 0.12), and the OD was 37.74 minutes shorter (95% CI =-55.44,-20.04) in POEM among observational studies, whereas it was not different among RCTs. The LOS and MAE were similar in the groups.Comparisons among studies yielded divergent results. RCTs revealed that POEM had a higher incidence of GERD in the early assessment, whereas observational studies showed higher clinical success and a shorter OD in POEM. Ultimately, the between-group difference waned over time in GERD in all comparisons, resulting in no difference among RCTs in the late evaluation. Our meta-analysis demonstrated a non -preferential treatment of achalasia between endoscopic or surgical cardiomyotomy, prioritizing an individualized approach in the long term.
- Endoscopic ultrasound (EUS)-guided cholecystostomy versus percutaneous cholecystostomy (PTC) in the management of acute cholecystitis in patients unfit for surgery: a systematic review and meta-analysis(2023) HEMERLY, Matheus Candido; MOURA, Diogo Turiani Hourneaux de; MONTE JUNIOR, Epifanio Silvino do; PROENCA, Igor Mendonca; RIBEIRO, Igor Braga; YVAMOTO, Erika Yuki; RIBAS, Pedro Henrique Boraschi Vieira; SANCHEZ-LUNA, Sergio A.; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux deBackground and aim Surgical cholecystectomy is the gold standard strategy for the management of acute cholecystitis (AC). However, some patients are considered unfit for surgery due to certain comorbid conditions. As such, we aimed to compare less invasive treatment strategies such as endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) and percutaneous gallbladder drainage (PT-GBD) for the management of patients with AC who are suboptimal candidates for surgical cholecystectomy. Methods A comprehensive search of multiple electronic databases was performed to identify all the studies comparing EUS-GBD versus PT-GBD for patients with AC who were unfit for surgery. A subgroup analysis was also performed for comparison of the group undergoing drainage via cautery-enhanced lumen-apposing metal stents (LAMS) versus PT-GBD. The outcomes included technical and clinical success, adverse events (AEs), recurrent cholecystitis, reintervention, and hospital readmission. Results Eleven studies including 1155 patients were included in the statistical analysis. There was no difference between PT-GBD and EUS-GBD in all the evaluated outcomes. On the subgroup analysis, the endoscopic approach with cautery-enhanced LAMS was associated with lower rates of adverse events (RD = - 0.33 (95% CI - 0.52 to - 0.14; p = 0.0006), recurrent cholecystitis (- 0.05 RD (95% CI - 0.09 to - 0.02; p = 0.02), and hospital readmission (- 0.36 RD (95% CI-0.70 to - 0.03; p = 0.03) when compared to PT-GBD. All other outcomes were similar in the subgroup analyses. Conclusions EUS-GBD using cautery-enhanced LAMS is superior to PT-GBD in terms of safety profile, recurrent cholecystitis, and hospital readmission rates in the management of patients with acute cholecystitis who are suboptimal candidates for cholecystectomy. However, when cautery-enhanced LAMS are not used, the outcomes of EUS-GBD and PT-GBD are similar. Thus, EUS-GBD with cautery-enhanced LAMS should be considered the preferable approach for gallbladder drainage for this challenging population.
- Gastric Emptying and Its Correlation With Weight Loss and Body Mass Index in Patients With an Intragastric Balloon: A Prospective Study With Six Years of Follow-Up(2022) BARRICHELLO, Sergio; RIBEIRO, Igor Braga; SOUZA, Thiago F. de; NETO, Manoel dos Passos Galvao; GRECCO, Eduardo; WAISBERG, JaquesBackgroundObesity is the most well-established and prolonged pandemic in modern society. Having a better understanding of the available tools is important to improve weight loss and make the strategies more productive. This study aims to evaluate the effect of intragastric balloon (IGB) on gastric emptying time, its relationship with weight loss after IGB removal, and weight maintenance after six years.MethodologyThis prospective study analyzed data from patients undergoing IGB placement. A six-years follow-up was performed and data about weight maintenance were collected. We analyzed the impact of the IGB on gastrointestinal motility and its correlation with weight loss. ResultsOf the 20 patients included in the study, 52.4% were diagnosed with class I obesity and 47.6% with class II obesity. The mean weight of the patients was 96.5 +/- 11.9 kg at baseline, 79.6 +/- 11.4 kg at the time of IGB removal, 81.8 +/- 9.1 kg at six months, and 93.2 +/- 14.3 kg six years after IGB removal. The mean difference between the initial weight and that measured immediately after IGB removal was 16.68 +/- 5.71 kg. Regarding gastric emptying time, there was a difference in retention on comparing the measurement before balloon placement to that after the balloon was in place (72.9% vs. 86.8%) after one hour of food intake. Comparing two hours after food intake, patients before IGB placement had a 30.6% food retention, while patients with IGB in place had a 69.2% retention.ConclusionsIn patients with class I or II obesity, the use of an IGB delayed gastric emptying of foods but showed no direct correlation with weight loss. Weight loss achieved after IGB placement was maintained in half of the patients at a six-year follow-up.
- Endoscopic Ultrasound-Guided Gastroenterostomy for the Palliation of Gastric Outlet Obstruction (GOO): A Systematic Review and Meta-analysis of the Different Techniques(2022) RIBAS, Pedro Henrique Boraschi V.; MOURA, Diogo Turiani H. De; PROENCA, Igor M.; MONTE JUNIOR, Epifanio S. Do; YVAMOTO, Erika Y.; HEMERLY, Matheus C.; OLIVEIRA, Victor L. De; RIBEIRO, Igor B.; SANCHEZ-LUNA, Sergio A.; BERNARDO, Wanderley M.; MOURA, Eduardo Guimaraes H. DeIntroduction: Gastric outlet obstruction (GOO) is usually associated with a poor prognosis and a significant decrease in a patient's quality of life. Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) using lumen-apposing metal stents (LAMS) has emerged as a safe and effective palliation procedure for GOO in patients that are unfit for surgery. Without an exclusive gold-standard technique for EUS-GE, we aimed to compare the currently available ones in this systematic review and meta-analysis, the first on this subspecialty. Methods: A comprehensive search from multiple electronic databases was performed. The search had a particular emphasis on the techniques used in performing EUS-GE. We identified all the studies in which EUS-GE was performed as palliation for GOO from its inception to the current date. The outcomes analyzed were the following: technical and clinical success, total and severe adverse events (AEs), procedure duration, and length of hospital stay (LOHS). Results: Twenty studies involving 863 patients were the basis of this statistical analysis. Patients underwent the following techniques: direct gastroenterostomy (DGE) (n=718), balloon-assisted gastroenterostomy (BAGE) (n=27), and endoscopic ultrasound (EUS)-guided double-balloon-occluded gastrojejunostomy bypass (n=118). In comparison to balloon-assisted techniques, DGE had a lower rate of AEs,-0.121 (95% CI-0.191 to-0.051 p=0.001); and LOHS for the DGE group,-2.684 (95% CI-1.031 to-4.337 p=0.001). The other analyzed outcomes presented no statistically significant differences. On a sub-analysis, BAGE showed a lower rate of AEs than EUS-guided double-balloon-occluded gastrojejunostomy bypass,-0.196 (95% CI -0.061 to-0.331 p=0.004). Conclusions: EUS-GE is a safe and effective procedure for palliating GOO. When correctly administered, any of the analyzed techniques may be used to palliate GOO with similar technical and clinical outcomes. DGE had significantly lower rates of AEs and LOHS, which can be inferred as a safer procedure. These results should be interpreted cautiously due to the limited few studies that are available and accessible. Therefore, further well-designed, randomized clinical studies on the topic are warranted to compare the different techniques from more sources.
- Impact of Endoscopic Sleeve Gastroplasty in Non-alcoholic Fatty Liver Disease: a Systematic Review and Meta-analysis(2023) NUNES, Beanie Conceicao Medeiros; MOURA, Diogo Turiani Hourneaux de; KUM, Angelo So Taa; OLIVEIRA, Guilherme Henrique Peixoto de; HIRSCH, Bruno Salomao; RIBEIRO, Igor Braga; GOMES, Igor Logetto Caetite; OLIVEIRA, Claudia Pinto Marques de; MAHMOOD, Sultan; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux deNon-alcoholic fatty liver disease (NAFLD) is the most common cause of liver disease worldwide. Endoscopic sleeve gastroplasty (ESG) has proven to be feasible, safe, and effective in the management of obesity. We performed the first systematic review and meta-analysis evaluating NAFLD and other metabolic parameters 12 months post-ESG. Four observational studies with a total of 175 patients were included. The results showed a significant (p < 0.05) reduction of 4.85 in hepatic steatosis index (95% CI - 6.02, - 3.67), 0.5 in NAFLD fibrosis score (95% CI - 0.80, - 0.19), 6.32 U/l in ALT (95% CI - 9.52, - 3.11), 17.28% in TWL (95% CI - 18.24, - 16.31), 6.31 kg/m(2) in BMI (95% CI - 8.11, - 4.52), 47.97% in EWL (95% CI - 49.10, - 46.84), and 0.51% in HbA1c (95% CI - 0.90, - 0.12). ESG improves liver parameters, provides weight loss, and reduces HbA1c levels in patients suffering from NAFLD.
- Laparoscopic-Assisted Endoscopic Retrograde Cholangiopancreatography (ERCP) Versus Endoscopic Ultrasound-Directed Transgastric ERCP in Patients With Roux-en-Y Gastric Bypass: A Systematic Review and Meta-Analysis(2022) OLIVEIRA, Victor L. de; MOURA, Diogo Turiani H. de; MONTE JUNIOR, Epifanio S. do; PROENCA, Igor M.; RIBEIRO, Igor B.; SANCHEZ-LUNA, Sergio A.; RIBAS, Pedro Henrique Boraschi V.; HEMERLY, Matheus C.; BERNARDO, Wanderley M.; MOURA, Eduardo Guimaraes H. deEndoscopic retrograde cholangiopancreatography (ERCP) is a therapeutic procedure for skilled endoscopists that can be even more challenging in some situations, including patients' post-Roux-en-y Gastric Bypass (RYGB) surgery. There is still no consensus on whether laparoscopic-assisted ERCP (LA-ERCP) or endoscopic ultrasound (EUS)-directed transgastric ERCP (EDGE) is the most appropriate, safe, and feasible approach in patients with this type of post-surgical anatomy. This systematic review and meta-analysis aimed to examine both approaches' feasibility, efficacy, and safety in this situation. We searched for electronic databases (MEDLINE, EMBASE, Lilacs, Google Scholar, and Central Cochrane) to identify studies comparing LA-ERCP versus EDGE. Outcomes measured included technical success, adverse events (AEs) and serious AEs, length of stay (LOS), and procedural time. Descriptive data related to the EDGE procedure was also extracted. The risk of bias and the quality of evidence of the enrolled studies were assessed. Five studies, totalizing 268 patients (176 LA-ERCP and 92 EDGE), were included. There was no statistical difference in technical success and AEs between groups; however, the LOS and procedural times were shorter for the EDGE group. High rates of fistula closure and no weight regain were observed in EDGE. Both methods are feasible and safe techniques to perform ERCP in patients with RYGB anatomy, with comparable technical success and adverse events rate. However, EDGE is associated with shorter LOS and procedural time.
- Modified endoscopic vacuum therapy for hypopharyngeal acute leakage after foreign body perforation(2022) SASSO, Joao Guilherme Ribeiro Jordao; YVAMOTO, Erika Yuki; ROCHA, Rodrigo Silva de Paula; RIBEIRO, Igor Braga; BOGHOSSIAN, Mateus Bond; MOURA, Diogo Turiani Hourneaux de; MOURA, Eduardo Guimaraes Hourneaux de
