| 1 | Comparison between endoscopic sphincterotomy vs endoscopic sphincterotomy associated with balloon dilation for removal of bile duct stones:A systematic review and meta-analysis based on randomized controlled trials显示文摘AIM To compare gallstones removal rate and incidence of bleeding, pancreatitis, use of mechanical lithotripsy, cholangitis and perforation between isolated sphincterotomy vs sphincterotomy associated with balloon dilation of papilla in choledocholithiasis through the meta-analysis of randomized clinical trials. METHODS We conducted a systematic review according to the PRISMA guidelines. Literature search was restricted to randomized controlled trials(RCTs) on Med Line, Cochrane Library, LILACS, and EMBASE database platforms in July 2017. The manual search included references of retrieved articles. We extracted data focusing on outcomes: The primary endpoint was the stones removal rate; Secondary endpoints were rates of pancreatitis, bleeding, use of mechanical lithotripsy(ML), perforation and cholangitis. RESULTS Eleven RCTs with 1824 patients were included. EST was associated with more post-endoscopic retrograde cholangiopancreatography(ERCP) bleeding [FE RD-0.02, CI(-0.03,-0.00), I2 = 33%, P = 0.05] and more need of mechanical lithotripsy in general [RE RD-0.16, CI(-0.25,-0.06), I2 = 90%, P = 0.002] and in subgroup analysis of stones greater than 15 mm [RE RD-0.20, CI(-0.38,-0.02), I2 = 82%, P = 0.003]. Incidence of pancreatitis [FE RD-0.01, CI(-0.03, 0.01), I2 = 0, P = 0.36], cholangitis [FE RD-0.00, CI(-0.01, 0.01), I2 =0, P = 0.97] and perforation [FE RD-0.01, CI(-0.01, 0.00), I2 = 0, P = 0.23] was similar between the groups as well as similar stone removal rates in general [FE RD-0.01, CI(-0.01, 0.04), I2 = 0, P = 0.23] and pooled analysis of stones greater than 15 mm [FE RD-0.02, CI(-0.02, 0.07), I2 = 11%, P = 0.31]. CONCLUSION Through meta-analysis of randomized clinical trials we found that isolated sphincterotomy was associated with more post-ERCP bleeding and more need for mechanical lithotripsy. However, there was no statistical difference in the stone removal rate between isolated sphincterotomy and sphincterotomy associated with balloon dilation in the approach to remove gallstones. | Cesar Capel de Clemente Junior Wanderley Marques Bernardo Tomazo Prince Franzini Gustavo Oliveira Luz Marcos Eduardo Lera dos Santos Jonah Maxwell Cohen Diogo Turiani Hourneaux de Moura Fábio Ramalho Tavares Marinho Martin Coronel Paulo Sakai Eduardo Guimaraes Hourneaux de Moura | 2018 | World Journal of Gastrointestinal Endoscopy2018，10，8： | 8 |
| 2 | Endoscopic ultrasound-guided vs endoscopic retrograde cholangiopancreatography biliary drainage for obstructed distal malignant biliary strictures: A systematic review and meta-analysis显示文摘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%n 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 were14 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 t group(MD =-0.22%; 95 CI:-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. | Fernanda P Logiudice Wanderlei M Bernardo Facundo Galetti Vitor M Sagae Carolina O Matsubayashi Antonio C Madruga Neto Vitor O Brunaldi Diogo T H de Moura Tomazo Franzini Spencer Cheng Sergio E Matuguma Eduardo G H de Moura | 2019 | World Journal of Gastrointestinal Endoscopy2019，11，4： | 6 |

| 16 | Biliary drainage in inoperable malignant biliary distal obstruction: A systematic review and meta-analysis显示文摘BACKGROUND Endoscopic drainage remains the treatment of choice for unresectable or inoperable malignant distal biliary obstruction(MDBO).AIM To compare the safety and efficacy of plastic stent(PS)vs self-expanding metal stent(SEMS)placement for treatment of MDBO.METHODS This meta-analysis was developed according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines.A comprehensive search was performed in MEDLINE,Cochrane,Embase,Latin American and Caribbean Health Sciences Literature,and grey literature to identify randomized clinical trials(RCTs)comparing clinical success,adverse events,stent dysfunction rate,reintervention rate,duration of stent patency,and mean survival.Risk difference(RD)and mean difference(MD)were calculated and heterogeneity was assessed with I2 statistic.Subgroup analyses were performed by SEMS type.RESULTS Twelve RCTs were included in this study,totaling 1005 patients.There was no difference in clinical success(RD=-0.03,95%confidence interval[CI]:-0.01,0.07;I 2=0%),rate of adverse events(RD=-0.03,95%CI:-0.10,0.03;I2=57%),and mean patient survival(MD=-0.63,95%CI:-18.07,19.33;I2=54%)between SEMS vs PS placement.However,SEMS placement was associated with a lower rate of reintervention(RD=-0.34,95%CI:-0.46,-0.22;I2=57%)and longer duration of stent patency(MD=125.77 d,95%CI:77.5,174.01).Subgroup analyses revealed both covered and uncovered SEMS improved stent patency compared to PS(RD=152.25,95%CI:37.42,267.07;I2=98%and RD=101.5,95%CI:38.91,164.09;I2=98%;respectively).Stent dysfunction was higher in the covered SEMS group(RD=-0.21,95%CI:-0.32,-0.1;I²=205%),with no difference in the uncovered SEMS group(RD=-0.08,95%CI:-0.56,0.39;I²=87%).CONCLUSION While both stent types possessed a similar clinical success rate,complication rate,and patient-associated mean survival for treatment of MDBO,SEMS were associated with a longer duration of stent patency compared to PS. | Maria Vitória Cury Vieira Scatimburgo Igor Braga Ribeiro Diogo Turiani Hourneaux de Moura Vitor Massaro Takamatsu Sagae Bruno Salomão Hirsch Mateus Bond Boghossian Thomas R McCarty Marcos EduardoLera dos Santos Tomazo Antonio Prince Franzini Wanderley Marques Bernardo Eduardo GuimarãesHourneaux de Moura | 2021 | World Journal of Gastrointestinal Surgery2021，13，5： | 0 |
