1Comparison between endoscopic sclerotherapy and band ligation for hemostasis of acute variceal bleeding显示文摘AIM:To compare band ligation(BL) with endoscopic sclerotherapy(SCL) in patients admitted to an emergency unit for esophageal variceal rupture. METHODS:A prospective,randomized,single-center study without crossover was conducted.After endoscopic diagnosis of esophageal variceal rupture,patients were randomized into groups for SCL or BL treatment.Sclerotherapy was performed by ethanolamine oleate intravascular injection both above and below the rupture point,with a maximum volume of 20 mL.For BL patients,banding at the rupture point was attempted,followed by ligation of all variceal tissue of the distal esophagus.Primary outcomes for both groups were initial failure of bleeding control(5 d) ,early re-bleeding(5 d to 6 wk),and complications,including mortality.From May 2005 to May 2007,100 patients with variceal bleeding were enrolled in thestudy:50 SCL and 50 BL patients.No differences between groups were observed across gender,age,ChildPugh status,presence of shock at admission,mean hemoglobin levels,and variceal size. RESULTS:No differences were found between groups for bleeding control,early re-bleeding rates,complications,or mortality.After 6 wk,36(80%) SCL and 33(77 %) EBL patients were alive and free of bleeding.A statistically significant association between Child-Pugh status and mortality was found,with 16%mortality in Child A and B patients and 84%mortality in Child C patients(P<0.001) . CONCLUSION:Despite the limited number of patients included,our results suggest that SCL and BL are equally efficient for the control of acute variceal bleeding.Gustavo Oliveira Luz Fauze Maluf-Filho Sérgio Eiji Matuguma Fábio Yuji Hondo Edson Ide Jeane Martins Melo Spencer Cheng Paulo Sakai 2011World Journal of Gastrointestinal Endoscopy2011,3,5:20
2Deep sedation during gastrointestinal endoscopy: Propofol-fentanyl and midazolam-fentanyl regimens显示文摘AIM: To compare deep sedation with propofol-fentanyl and midazolam-fentanyl regimens during upper gastrointestinal endoscopy. METHODS: After obtaining approval of the research ethics committee and informed consent, 200 patients were evaluated and referred for upper gastrointestinal endoscopy. Patients were randomized to receive propofol-fentanyl or midazolam-fentanyl (n = 100/group).We assessed the level of sedation using the observer's assessment of alertness/sedation (OAA/S) score and bispectral index (BIS). We evaluated patient and physician satisfaction, as well as the recovery time and complication rates. The statistical analysis was performed using SPSS statistical software and included the MannWhitney test, χ 2 test, measurement of analysis of variance, and the κ statistic. RESULTS: The times to induction of sedation, recovery, and discharge were shorter in the propofolfentanyl group than the midazolam-fentanyl group. According to the OAA/S score, deep sedation events occurred in 25% of the propofol-fentanyl group and 11% of the midazolam-fentanyl group (P = 0.014). Additionally, deep sedation events occurred in 19% of the propofol-fentanyl group and 7% of the midazolamfentanyl group according to the BIS scale (P = 0.039). There was good concordance between the OAA/S score and BIS for both groups (κ = 0.71 and κ = 0.63, respectively). Oxygen supplementation was required in 42% of the propofol-fentanyl group and 26% of the midazolam-fentanyl group (P = 0.025). The mean time to recovery was 28.82 and 44.13 min in the propofolfentanyl and midazolam-fentanyl groups, respectively (P < 0.001). There were no severe complications in either group. Although patients were equally satisfied with both drug combinations, physicians were more satisfied with the propofol-fentanyl combination. CONCLUSION: Deep sedation occurred with propofolfentanyl and midazolam-fentanyl, but was more frequent in the former. Recovery was faster in the propofol-fentanyl group.Marcos Eduardo Lera dos Santos Fauze Maluf-Filho Dalton Marques Chaves Sergio Eiji Matuguma Edson Ide Gustavo de Oliveira Luz Thiago Ferreira de Souza Fernanda C Simoes Pessorrusso Eduardo Guimares Hourneaux de Moura Paulo Sakai 2013World Journal of Gastroenterology2013,19,22:16
3Endoscopic stenting for inoperable malignant biliary obstruction: A systematic review and meta-analysis显示文摘AIM: To analyze through meta-analyses the benefits of two types of stents in the inoperable malignant biliary obstruction.METHODS: A systematic review of randomized clinical trials(RCT) was conducted, with the last update on March 2015, using EMBASE, CINAHL(EBSCO), MEDLINE, LILACS/CENTRAL(BVS), SCOPUS, CAPES(Brazil), and gray literature. Information of the selected studies was extracted in sight of six outcomes: primarily regarding dysfunction, complication and reintervention rates; and secondarily costs, survival, and patency time. The data about characteristics of trial participants, inclusion and exclusion criteria and types of stents were also extracted. The bias was mainly assessed through the JADAD scale. This meta-analysis was registered in the PROSPERO database by the number CRD42014015078. The analysis of the absolute risk of the outcomes was performed using the software Rev Man, by computing risk differences(RD) of dichotomous variables and mean differences(MD) of continuous variables. Data on RD and MD for each primary outcome were calculated using the MantelHaenszel test and inconsistency was qualified and reported in χ2 and the Higgins method(I2). Sensitivity analysis was performed when heterogeneity was higher than 50%, a subsequent assay was done and other findings were compiled. Student's t-test was used for the comparison of weighted arithmetic means regarding secondary outcomes.RESULTS: Initial searching identified 3660 studies; 3539 were excluded through title, repetition, and/or abstract, while 121 studies were fully assessed and were excluded mainly because they did not compare self-expanding metal stents(SEMS) and plastic stents(PS), leading to thirteen RCT selected, with 13 articles and 1133 subjects meta-analyzed. The mean age was 69.5 years old, that were affected mostly by bile duct(proximal) and pancreatic tumors(distal). The preferred SEMS diameter used was the 10 mm(30 Fr) and the preferred PS diameter used was 10 Fr. In the metaanalysis, SEMS had lower overall stent dysfunction compared to PS(21.6% vs 46.8%, P < 0.00001) and fewer re-interventions(21.6% vs 56.6%, P < 0.00001), with no difference in complications(13.7% vs 15.9%, P = 0.16). In the secondary analysis, the mean survival rate was higher in the SEMS group(182 d vs 150 d, P < 0.0001), with a higher patency period(250 d vs 124 d, P < 0.0001) and a lower cost per patient(4193.98 vs 4728.65 Euros, P < 0.0985).CONCLUSION: SEMS are associated with lower stent dysfunction, lower re-intervention rates, better survival, and higher patency time. Complications and costs showed no difference.Leonardo Zorrón Pu Eduardo Guimaraes Hourneaux de Moura Wanderley Marques Bernardo Felipe Iankelevich Baracat Ernesto Quaresma Mendonca AndréKondo Gustavo Oliveira Luz Carlos Kiyoshi Furuya Júnior Everson Luiz de Almeida Artifon 2015World Journal of Gastroenterology2015,21,47:10
4Comparison 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 2018World Journal of Gastrointestinal Endoscopy2018,10,8:8
5Pancreatitis after endoscopic retrograde cholangiopancreatography:A narrative review显示文摘Acute post-endoscopic retrograde cholangiopancreatography pancreatitis(PEP)is a feared and potentially fatal complication that can be as high as up to 30%in high-risk patients.Pre-examination measures,during the examination and after the examination are the key to technical and clinical success with a decrease in adverse events.Several studies have debated on the subject,however,numerous topics remain controversial,such as the effectiveness of prophylactic medications and the amylase dosage time.This review was designed to provide an update on the current scientific evidence regarding PEP available in the literature.Igor Braga Ribeiro Epifanio Silvino do Monte Junior Antonio Afonso Miranda Neto Igor Mendonça Proença Diogo Turiani Hourneaux de Moura Mauricio Kazuyoshi Minata Edson Ide Marcos Eduardo Lera dos Santos Gustavo de Oliveira Luz Sergio Eiji Matuguma Spencer Cheng Renato Baracat Eduardo Guimarães Hourneaux de Moura 2021World Journal of Gastroenterology2021,27,20:5
