    Endoscopic versus surgical treatment for pancreatic pseudocysts Systematic review and meta-analysis
    (2019) FARIAS, Galileu F. A.; BERNARDO, Wanderley M.; MOURA, Diogo T. H. De; GUEDES, Hugo G.; BRUNALDI, Vitor O.; VISCONTI, Thiago A. de C.; GONCALVES, Caio V. T.; SAKAI, Christiano M.; MATUGUMA, Sergio E.; SANTOS, Marcos E. L. dos; SAKAI, Paulo; MOURA, Eduardo G. H. De
    Objective: This systematic review and meta-analysis aims to compare surgical and endoscopic treatment for pancreatic pseudocyst (PP). Methods: The researchers did a search in Medline, EMBASE, Scielo/Lilacs, and Cochrane electronic databases for studies comparing surgical and endoscopic drainage of PP s in adult patients. Then, the extracted data were used to perform a meta-analysis. The outcomes were therapeutic success, drainage-related adverse events, general adverse events, recurrence rate, cost, and time of hospitalization. Results: There was no significant difference between treatment success rate (risk difference [RD] -0.09; 95% confidence interval [CI] [0.20,0.01]; P = .07), drainage-related adverse events (RD -0.02; 95% CI [-0.04,0.08]; P = .48), general adverse events (RD -0.05; 95% CI [-0.12, 0.02]; P = .13) and recurrence (RD: 0.02; 95% CI [-0.04,0.07]; P = .58) between surgical and endoscopic treatment. Regarding time of hospitalization, the endoscopic group had better results (RD: -4.23; 95% CI [-5.18, -3.29]; P < .00001). When it comes to treatment cost, the endoscopic arm also had better outcomes (RD: -4.68; 95% CI [-5.43,-3.94]; P < .00001). Conclusion: There is no significant difference between surgical and endoscopic treatment success rates, adverse events and recurrence for PP. However, time of hospitalization and treatment costs were lower in the endoscopic group.

    Computed tomography colonography versus colonoscopy for the diagnosis of colorectal cancer: a systematic review and meta-analysis
    (2018) DUARTE, Ralph B.; BERNARDO, Wanderley M.; SAKAI, Christiano M.; SILVA, Gustavo L. R.; GUEDES, Hugo G.; KUGA, Rogerio; IDE, Edson; ISHIDA, Robson K.; SAKAI, Paulo; MOURA, Eduardo G. H. de
    Colorectal cancer (CRC) is a significant cause of morbidity and mortality. Optical colonoscopy (OC) is the first choice of investigation for assessing the state of the colon and it is excellent for CRC screening. Newer technologies such as computed tomography colonography (CTC) may also be useful in CRC screening. This systematic review compares the benefits of CTC and OC for CRC screening. This review includes all the available randomized clinical trials comparing CTC and OC for CRC screening in asymptomatic patients. Three studies were included in the systematic review and were submitted for meta-analysis. In the analysis of participation rates, only 2,333 of 8,104 (29%) patients who were invited for screening underwent the CTC, and only 1,486 of the 7,310 (20%) patients who were invited for screening underwent OC. The absolute risk difference in participation rate in the two procedures was 0.1 (95% CI, 0.05-0.14) in favor of CTC. In the analysis of advanced colorectal neoplasia (ACN) detection rates, 2,357 patients undergoing CTC and 1,524 patients undergoing OC were included. Of these, 135 patients (5.7%) who underwent a CTC and 130 patients (8.5%) who underwent an OC were diagnosed with ACN. The absolute risk difference in ACN detection rate in the two procedure types was -0.02 (with a 95% CI between -0.04 and -0.00) in favor of OC. CTC is an option for CRC screening in asymptomatic patients. However, as CTC was inferior in detecting ACN, it should not replace OC, which remains the gold standard.

    Cholangioscopy-guided steroid injection for refractory post liver transplant anastomotic strictures: a rescue case series
    (2019) FRANZINI, Tomazo; SAGAE, Vitor M. T.; GUEDES, Hugo G.; SAKAI, Paulo; WAISBERG, Daniel R.; ANDRAUS, Wellington; D'ALBUQUERQUE, Luiz A. C.; SETHI, Amrita; MOURA, Eduardo G. H. de
    Background and aims: Post liver transplant biliary anastomotic strictures have traditionally been treated with balloon dilation and multiple plastic stents. Fully covered self-expandable metallic stents may be used as an initial alternative or after multiple plastic stents failure. Refractory strictures can occur in 10-22% and require revisional surgery. Alternatively, cholangioscopy allows direct visualization and therapeutic approaches. We aimed to assess the feasibility, safety, and efficacy of balloon dilation combined with cholangioscopy-guided steroid injection for the treatment of refractory anastomotic biliary strictures. Methods: Three post-orthotopic liver transplant patients who failed standard treatment of their biliary anastomotic strictures underwent endoscopic retrograde cholangiopancreatography with balloon dilation followed by cholangioscopy-guided steroid injection at a tertiary care center. Patients had follow-up with images and laboratorial tests to evaluate for residual stricture. Results: Technical success of balloon dilation+cholangioscopy-guided steroid injection was achieved in all patients. Cholangioscopy permitted accurate evaluation of bile ducts and precise localization for steroid injection. No adverse events occurred. Mean follow-up was 26 months. Two patients are stent free and remain well in follow-up, with no signs of biliary obstruction. No further therapeutic endoscopic procedures or revisional surgery were required. One patient did not respond to balloon dilation+cholangioscopy-guided steroid injection after 11 months of follow-up and required repeat balloon dilation of new strictures above the anastomosis. Conclusion: Cholangioscopy-guided steroid injection combined with balloon dilation in the treatment of refractory post liver transplant strictures is feasible and safe. This method may be used as a rescue alternative before surgical approach. Randomized controlled trials comparing balloon dilation+cholangioscopy-guided steroid injection to fully covered self-expandable metallic stents are needed to determine the role of this treatment for anastomotic biliary strictures.

    Recurrent acute pancreatitis caused by pancreatic biliary maljunction due to long common channel
    (2016) FARIAS, Galileu F. A.; OTOCH, Jose P.; GUEDES, Hugo G.; ARTIFON, Everson L. A.
    The pancreatic biliary maljunction is a rare anomaly that affects mainly females, defined as an anatomical maljunction of the pancreatic duct and the biliary duct confluence, and may be a rare cause of recurrent acute pancreatitis. In order to early diagnosis and prompt treatment, ERCP has an important role in it
