    (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 de
    Background 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.

    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 de
    Organized 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 de
    Peroral 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.

    Complex Intrahepatic Lithiasis: A Case Report of Combined Treatment With Surgical Exploration of the Bilioenteric Anastomosis and Laser Lithotripsy by Cholangioscopy
    (2023) SANTOS, Marcos Eduardo Lera dos; SASSO, Joao Guilherme Ribeiro Jordao; FIGUEIRA, Estela R.; OLIVEIRA, Victor L. De; ARABI, Arthur Youssif Mota; MEIRA JUNIOR, Jose Donizeti; SILVA, Nathalia Camin Calixto Sarroche da; MOURA, Diogo Turiani De; JUKEMURA, Jose; MOURA, Eduardo Guimaraes De
    Intrahepatic lithiasis, or hepatolithiasis, is an endemic disease in southeast Asia, although, with immigration from Eastern countries, the incidence of this pathology is rising worldwide. The Latin American experience demonstrates morbidity and mortality compatible with other Western countries, but minimally invasive procedures are lacking. We demonstrate a case of a combined surgical and endoscopic approach for stone clearance.We present a case of a 47-year-old female patient with biliary enteric anastomosis to treat recurrent pyogenic cholangitis resulting from intrahepatic lithiasis. The patient was admitted to the emergency room, presented with a new episode of cholangitis, and submitted to transcutaneous hepatobiliary drainage. The multidisciplinary approach, including the endoscopic and surgical teams, successfully performed the stone clearance with laser lithotripsy and stone removal by open access. The postoperative period was uneventful, and the patient did not present any sign of recurrence after one year. A combined surgical and endoscopic approach achieved short-term clinical and technical success in this novel case. Moreover, individualizing cases requiring open surgical access is feasible, which allows a combined endoscopic approach with safety.

    Endoscopic Resection Versus Surgery in the Treatment of Early Gastric Cancer: A Systematic Review and Meta-Analysis
    (2022) BESTETTI, Alexandre Moraes; MOURA, Diogo Turiani Hourneaux de; PROENCA, Igor Mendonca; MONTE JUNIOR, Epifanio Silvino do; RIBEIRO, Igor Braga; SASSO, Joao Guilherme Ribeiro Jordao; KUM, Angelo So Taa; SANCHEZ-LUNA, Sergio A.; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux de
    Background and Aim: Endoscopic resection (ER) is the preferred approach to treat early gastric cancer (EGC) in patients without suspected lymph node involvement and that meet the criteria for ER. Surgery is a more aggressive treatment, but it may be associated with less recurrence and the need for reintervention. Previous meta-analyses comparing ER with surgery for EGC did not incorporate the most recent studies, making accurate conclusions not possible. Methods: This systematic review and meta-analysis aimed to examine complete resection, length of hospital stay (LOHS), adverse events (AEs), serious AEs, recurrence, 5-year overall survival (OS), and 5-year cancer-specific survival (CSS) in patients with EGC. Results: A total of 29 cohorts studies involving 20559 patients were included. The ER (n = 7709) group was associated with a lower incidence of AEs (RD = -0.07, 95%CI = -0.1, -0.04, p < 0.0001) and shorter LOHS (95% CI -5.89, -5.32; p < 0,00001) compared to surgery (n = 12850). However, ER was associated with lower complete resection rates (RD = -0.1, 95%CI = -0.15, -0.06; p < 0.00001) and higher rates of recurrence (RD = 0.07, 95%CI = 0.06; p < 0.00001). There were no significant differences between surgery and ER in 5-year OS (RD = -0.01, 95%CI = -0.04, 0.02; p = 0.38), 5-year CSS (RD = 0.01, 95%CI = 0.00, 0.02; p < 0.17), and incidence of serious AEs (RD = -0.03, 95%CI = -0.08, 0.01; p = 0.13). Conclusions: ER and surgery are safe and effective treatments for EGC. ER provides lower rates of AEs and shorter LOHS compared to surgery. Although ER is associated with lower complete resection rates and a higher risk of recurrence, the OS and CSS were similar between both approaches.Systematic Review Registrationhttps://www.crd.york.ac.uk/PROSPERO/, identifier CRD42021255328.
