    (2019) SERRANO, Juan Pablo Roman; MOURA, Diogoturiani Hourneaux de; BERNARDO, Wanderley Marques; RIBEIRO, Igor Braga; FRANZINI, Tomazo Prince; MOURA, Eduardo Turiani Hourneaux de; BRUNALDI, Vitor Ottoboni; SALESSE, Marianne Torrezan; SAKAI, Paulo; MOURA, Eduardo Guimaraes Hourneaux De
    Background and study aims Endoscopic retrograde cholangiopancreatography (ERCP) is the primary therapeutic procedure for treatment of diseases that affect the biliary tree and pancreatic duct. While the therapeutic success rate of ERCP is high, the procedure can cause complications, such as acute pancreatitis (PEP), bleeding, and perforation. This meta-analysis aimed to assess the efficacy of nonsteroidal anti-inflammatory drugs (NSAIDs) in preventing PEP following (ERCP). Materials and methods We searched databases, such as MEDLINE, Embase, and Cochrane Central Library. Only randomized controlled trials (RCTs) that compared the efficacy of NSAIDs and placebo for the prevention of PEP were included. Outcomes assessed included incidence of PEP, severity of pancreatitis, route of administration, and type of NSAIDs. Results Twenty-one RCTs were considered eligible with a total of 6854 patients analyzed. Overall, 3427 patients used NSAIDs before ERCP and 3427 did not use the drugs (control group). In the end, 250 cases of acute pancreatitis post-ERCP were diagnosed in the NSAIDs group and 407 cases in the placebo group. Risk for PEP was lower in the NSAID group (risk difference (RD): -0.05; 95% confidence interval (CI): -0.07 to -0.03; number need to treat (NNT), 20; P<0.05). Use of NSAIDs effectively prevented mild pancreatitis compared with use of placebo (2.5% vs. 4.1%; 95% CI, -0.05 to -0.01; NNT, 33; P<0.05), but the information on moderate and severe PEP could not be completely elucidated. Only rectal administration reduced incidence of PEP (6.8% vs. 13 %; 95% CI, -0.10 to -0.04; NNT, 20; P<0.05). Furthermore, only diclofenac or indomethacin use was effective in preventing PEP. Conclusions Rectal administration of diclofenac and indomethacin significantly reduced risk of developing mild PEP. Further RCTs are needed to compare efficacy between NSAID administration pathways in prevention of PEP after ERCP.

    Efficacy of digital single-operator cholangioscopy in the visual interpretation of indeterminate biliary strictures: a systematic review and meta-analysis
    (2020) OLIVEIRA, Pedro Victor Aniz Gomes de; MOURA, Diogo Turiani Hourneaux de; RIBEIRO, Igor Braga; BAZARBASHI, Ahmad Najdat; FRANZINI, Tomazo Antonio Prince; SANTOS, Marcos Eduardo Lera dos; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux de
    Objective Indeterminate biliary strictures remain a significant diagnostic challenge. Digital single-operator cholangioscopy (D-SOC) incorporates digital imaging which enables higher resolution for better visualization and diagnosis of biliary pathology. We aimed to conduct a systematic review and meta-analysis of available literature in an attempt to determine the efficacy of D-SOC in the visual interpretation of indeterminate biliary strictures. Material and methods Electronic searches were performed using Medline (PubMed), EMBASE, and Cochrane Library. All D-SOC studies that reported the diagnostic performance in visual interpretation of indeterminate biliary strictures and biliary malignancies were included. The Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2 was used to evaluate the quality of the included studies. All data were extracted and pooled to construct a 2 x 2 table. The visual interpretation of D-SOC was compared to resected surgical specimens or clinical follow-up in the included patients. Pooled sensitivity, specificity, positive predictive value, negative predictive value, prevalence, positive likelihood ratio (+LR), negative likelihood ratio (-LR), and diagnostic odds ratio (OR) were calculated. The summarized receiver operating characteristic (SROC) curve corresponding with the area under the curve (AUC) was also analyzed. Results The search yielded 465 citations. Of these, only six studies with a total of 283 procedures met inclusion criteria and were included in the meta-analysis. The overall pooled sensitivity and specificity of D-SOC in the visual interpretation of biliary malignancies was 94% (95% CI 89-97) and 95% (95%CI 90-98), respectively, while +LR, -LR, diagnostic OR, and AUC were 15.20 (95%CI 5.21-44.33), 0.08 (95%CI 0.04-0.14), 308.83 (95%CI 106.46-872.82), and 0.983, respectively. The heterogeneity among 6 included studies was moderate for specificity (I-2 = 0.51) and low for sensitivity (I-2 = 0.17) and diagnostic OR (I-2 = 0.00). Conclusion D-SOC is associated with high sensitivity and specificity in the visual interpretation of indeterminate biliary strictures and malignancies. D-SOC should be considered routinely in the diagnostic workup of indeterminate biliary lesions.

    Early Endoscopic Retrograde Cholangiopancreatography Versus Conservative Treatment in Patients With Acute Biliary Pancreatitis: Systematic Review and Meta-analysis of Randomized Controlled Trials
    (2018) COUTINHO, Lara M. de A.; BERNARDO, Wanderley M.; ROCHA, Rodrigo S.; MARINHO, Fabio R.; DELGADO, Aureo; MOURA, Eduardo T. H.; MATUGUMA, Sergio E.; CHAVES, Dalton; FRANZINI, Tomazo A. P.; SAKAI, Paulo; MOURA, Eduardo G. H. de
    Objectives The aim of the study was to evaluate the role of early endoscopic retrograde cholangiopancreatography (ERCP) in the treatment of acute biliary pancreatitis, in comparison with conservative treatment. Methods Systematic review via databases (MEDLINE [PubMed], Latin-American and Caribbean Health Sciences Literature database, Embase, Cochrane Central, and the [Brazilian] Regional Library of Medicine) is conducted. We analyzed 10 randomized controlled trials (1091 patients). Outcomes were the following: local and systemic adverse events; acute cholangitis; death; length of hospital stay; cost; abdominal pain; and time to a reduction in body temperature. For the meta-analysis, we used risk difference (RD) and mean with standard deviation as measures of variability. Results There was a statistically significant difference between the patients submitted to ERCP in terms of the following: local adverse events (RD, 0.74; 95% confidence interval [CI], 0.55-0.99), time to pain relief and time to a reduction in axillary temperature (RD, -5.01; 95% CI, -6.98 to -3.04, and RD, -1.70; 95 CI%, -2.33 to -1.08, respectively). Patients undergoing ERCP spent less time in hospital (RD, -11.04; 95% CI, -15.15 to -6.93). Cost was lower in the group treated with ERCP. Conclusions Early ERCP decreases local adverse events, shortening the time to pain relief, to a reduction in axillary temperature, hospital stays, and cost in patients with acute biliary pancreatitis.

    (2021) SCATIMBURGO, Maria Vitoria Cury Vieira; RIBEIRO, Igor Braga; MOURA, Diogo Turiani Hourneaux de; SAGAE, Vitor Massaro Takamatsu; HIRSCH, Bruno Salomao; BOGHOSSIAN, Mateus Bond; MCCARTY, Thomas R.; SANTOS, Marcos Eduardo Lera dos; FRANZINI, Tomazo Antonio Prince; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux de
    Y 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 I-2 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; I-2 = 57%), and mean patient survival (MD = -0.63, 95%CI: -18.07, 19.33; I-2 = 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; I-2 = 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; I-2 = 98% and RD = 101.5, 95%CI: 38.91, 164.09; I-2 = 98%; respectively). Stent dysfunction was higher in the covered SEMS group (RD = -0.21, 95%CI: -0.32, -0.1; I-2 = 205%), with no difference in the uncovered SEMS group (RD = -0.08, 95%CI: -0.56, 0.39; I-2 = 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.

    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.

    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
    (2018) CLEMENTE JUNIOR, Cesar Capel de; BERNARDO, Wanderley Marques; FRANZINI, Tomazo Prince; LUZ, Gustavo Oliveira; SANTOS, Marcos Eduardo Lera dos; COHEN, Jonah Maxwell; MOURA, Diogo Turiani Hourneaux de; MARINHO, Fabio Ramalho Tavares; CORONEL, Martin; SAKAI, Paulo; MOURA, Eduardo Guimaraes Hourneaux de
    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 MedLine, 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), I-2 = 33%, P = 0.05] and more need of mechanical lithotripsy in general [RE RD-0.16, CI (-0.25, -0.06), I-2 = 90%, P = 0.002] and in subgroup analysis of stones greater than 15 mm [RE RD-0.20, CI (-0.38, -0.02), I-2 = 82%, P = 0.003]. Incidence of pancreatitis [FE RD-0.01, CI (-0.03, 0.01), I-2 = 0, P = 0.36], cholangitis [FE RD-0.00, CI (-0.01, 0.01), I-2 = 0, P = 0.97] and perforation [FE RD-0.01, CI (-0.01, 0.00), I-2 = 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), I-2 = 0, P = 0.23] and pooled analysis of stones greater than 15 mm [FE RD-0.02, CI (-0.02, 0.07), I-2 = 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.

    Efficacy and safety of carbon dioxide insufflation versus air insufflation during endoscopic retrograde cholangiopancreatography in randomized controlled trials: a systematic review and meta-analysis
    (2019) PASSOS, Marina Lordello; RIBEIRO, Igor Braga; MOURA, Diogo Turiani Hourneaux de; KORKISCHKO, Nadia; SILVA, Gustavo Luis Rodela; FRANZINI, Tomazo Prince; BERNANDO, Wanderley Marques; MOURA, Eduardo Guimaraes Horneaux de
    Background and study aims Ambient air is the most commonly used gas for insufflation in endoscopic procedures worldwide. However, prolonged absorption of air during endoscopic examinations may cause pain and abdominal distension. Carbon dioxide insufflation (CO (2) i) has been increasingly used as an alternative to ambient air insufflation (AAi) in many endoscopic procedures due to its fast diffusion properties and less abdominal distention and pain. For endoscopic retrograde cholangiopancreatography (ERCP), use of CO (2) for insufflation is adequate because this procedure is complex and prolonged. Some randomized controlled trials (RCTs) have evaluated the efficacy and safety of CO (2) as an insufflation method during ERCP but presented conflicting results. This systematic review and meta-analysis with only RCTs evaluated the efficacy and safety of CO (2) i versus AAi during ERCP. Methods A literature search was performed using online databases with no restriction regarding idiom or year of publication. Data were extracted by two authors according to a predefined data extraction form. Outcomes evaluated were abdominal pain and distension, complications, procedure duration, and CO (2) levels. Results Eight studies (919 patients) were included. Significant results favoring CO (2) i were less abdominal distension after 1h (MD: -1.41 [-1.81; -1.0], 95% CI, I-2=15%, P <0.00001) and less abdominal pain after 1h (MD: -23.80 [-27.50; -20.10], 95%CI, I-2=9%, P <0.00001) and after 6h (MD: -7.00 [-8.66; -5.33]; 95% CI, I-2=0%, P <0.00001). Conclusion Use of CO (2) i instead of AAi during ERCP is safe and associated with less abdominal distension and pain after the procedure.
