    (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.

    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.

    (2019) PORTELA, Joaquim Coelho da Cruz; BERNARDO, Wanderley Marques; MOURA, Diogo Turiani Hourneaux de; FRANZINI, Tomazo Antonio Prince; COUTINHO, Lara Meireles de Azeredo; BRUNALDI, Vitor Ottoboni; GUEDES, Hugo Goncalo; MOURA, Eduardo Turiani Hourneaux de; SANTOS, Marcos Eduardo Lera dos; LUZ, Gustavo Oliveira; MOURA, Eduardo Guimaraes Hourneaux de
    Background and Aims Acute pancreatitis is one common and severe complication after endoscopic retrograde cholangiopancreatography. Randomized controlled trials have reported that pancreatic stenting may efficiently prevent post-ERCP pancreatitis. Methods Systematic review was conducted on MEDLINE/PubMed and other databases randomized controlled trials comparing patients undergoing endoscopic retrograde cholangiopancreatography with pancreatic stent versus endoscopic retrograde cholangiopancreatography without stent. Two independent reviewers assessed the eligibility. Primary outcome is to assess the degree of severity of pancreatitis (mild, moderate, and severe) and secondary hyperamylasemia, cholangitis, abdominal pain, duration of endoscopic retrograde cholangiopancreatography and length of hospital stay. Results Twelve randomized controlled trials selected a total of 3.310 patients. Meta-analysis showed that pancreatic stenting reduced pancreatitis risk to PEP (mild PEP: RD 0.06, 95% CI-0.09 - 0.03; moderate PEP: RD 0.03, 95 % CI-0.06 - 0.01; severe PEP: (RD 0.02, 95% CI-0.05-0.01); Hyperaylasemia (RD-0.62, 95% CI-0.65-0.59) showed statistically significant difference. Cholangitis (RD 0.03, 95% CI-0.03-0.09), abdominal pain (RD 0.10, 95% CI-0.21-0.01), length of hospital stay after ERCP (RD 1.55, 95% CI-4.39 - 1.29), total duration of the procedure (RD 2.97, 95% CI-0.19-6.12), showed no statistical significance. Conclusions Pancreatic stent placement is effective in reducing post-endoscopic retrograde cholangiopancreatography acute pancreatitis incidence in high-risk patients.

    Endoscopic ultrasound-guided vs endoscopic retrograde cholangiopancreatography biliary drainage for obstructed distal malignant biliary strictures: A systematic review and meta-analysis
    (2019) LOGIUDICE, Fernanda P.; BERNARDO, Wanderlei M.; GALETTI, Facundo; SAGAE, Vitor M.; MATSUBAYASHI, Carolina O.; MADRUGA NETO, Antonio C.; BRUNALDI, Vitor O.; MOURA, Diogo T. H. de; FRANZINI, Tomazo; CHENG, Spencer; MATUGUMA, Sergio E.; MOURA, Eduardo G. H. de
    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% 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 were 14 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 group (MD = -0.22%; 95CI:-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.

    Adverse events after biliary sphincterotomy: Does the electric current mode make a difference? A systematic review and meta-analysis of randomized controlled trials
    (2020) FUNARI, Mateus Pereira; RIBEIRO, Igor Braga; MOURA, Diogo Turiani Hourneaux de; BERNARDO, Wanderley Marques; BRUNALDI, Vitor Ottoboni; REZENDE, Daniel Tavares; RESENDE, Ricardo Hannum; MARCO, Michele Oliveira de; FRANZINI, Tomazo Antonio Prince; MOURA, Eduardo Guimaraes Hourneaux de
    Background: Biliary sphincterotomy is an invasive method that allows access to the bile ducts, however, this procedure is not exempt of complications. Studies in the literature indicate that the mode of electric current used for sphincterotomy may carry different incidences of adverse events such as pancreatitis, hemorrhage, perforation, and cholangitis. Aim: To evaluate the safety of different modes of electrical current during biliary sphincterotomy based on incidence of adverse events. Methods: We searched articles for this systematic review in Medline, EMBASE, Central Cochrane, Lilacs, and gray literature from inception to September 2019. Data from studies describing different types of electric current were meta-analyzed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The following electric current modalities were evaluated: endocut, blend, pure cut, pure cut followed by blend, monopolar, and bipolar. Results: A total of 1791 patients from 11 randomized clinical trials evaluating the following comparisons: 1. Endocut vs Blend: No statistical difference in the incidence of bleeding (7% vs 13.4%; RD: -0.11 [-0.31, 0.08], P=0.27, I-2=86%), pancreatitis (4.4% vs 3.5%; RD: 0.01 [-0.03, 0.04], P=0.62, I-2=48%) and perforation (absence of cases in both arms). 2. Endocut vs Pure cut: Higher incidence of mild bleeding (without drop in hemoglobin levels, clinical repercussion or need for endoscopic intervention) in the pure cut group (9.2% vs 28.8%; RD: -0.19 [-0.27, -0.12], P<0.00001, I-2=0%). No statistical difference regarding pancreatitis (5.2% vs 0.9%; RD: 0.05 [-0.01, 0.11], P=0.12, I-2=57%), perforation (0.4% vs 0%; RD: 0.00 [-0.01, 0.02], P=0.7, I-2=0%) or cholangitis (1.8% vs 3.2%; RD: -0.01 [-0.09, 0.06], P=0,7). 3. Pure cut vs blend: higher incidence of mild bleeding in the pure cut group (40.4% vs 16.7%; RD: 0.24 [0.15, 0.33], P<0.00001, I-2=0%). No statistical difference concerning incidence of pancreatitis or cholangitis. 4. Pure cut vs Pure cut followed by Blend: No statistical difference regarding incidence of bleeding (22.5% vs 11.7%; RD: -0.10 [-0.24, 0.04], P=0.18, I-2=61%) and pancreatitis (8.9% vs 14.8%; RD 0.06 [-0.02, 0.13], P=0.12, I-2=0%). 5. Blend vs pure cut followed by blend: no statistical difference regarding incidence of bleeding and pancreatitis (11.3% vs 10.4%; RD -0.01 [-0.11, 0.09], P=0.82, I-2=0%). 6. Monopolar vs bipolar: higher incidence of pancreatitis in the monopolar mode group (12% vs 0%; RD 0.12 [0.02, 0.22], P=0.01). Conclusion: Pure cut carries higher incidences of mild bleeding compared to endocut and blend. However, this modality might present a lower incidence of pancreatitis. The monopolar mode elicits higher rates of pancreatitis in comparison with the bipolar mode. There is no difference in incidence of cholangitis or perforation between different types of electric current. There is a lack of evidence in the literature to recommend one method over the others, therefore new studies are warranted. As there is no perfect electric current mode, the choice in clinical practice must be based on the patient risk factors.
