Objective: Through this systematic review and meta-analysis, we aim to clarify the differences between these two techniques, thus improving primary success cannulation and reducing complications during endoscopic retrograde cholangiopancreatography, primarily pancreatitis. Methods: A comprehensive search was conducted to search for data available up until June2015from the most important databases available in the health field: EMBASE, MEDLINE (via PubMed), Cochrane, LILACS and CENTRAL (via BVS), SCOPUS, the CAPES database (Brazil), and gray literature. Results: Nine randomized clinical trialsincluding2583 people were selected from20,198 studies for meta-analysis. Choledocholithiasis had been diagnosed in mostly (63.8%) of the patients, who were aged an average of 63.15 years. In those patients treated using the guide wire-assisted cannulation technique, provided a significantly lower ins...

Background: Barrett’s esophagus (BE) is the main risk factor for esophageal adenocarcinoma. Its therapeutic approach is controversial and surgical treatment in the presence of high-grade intraepithelial neoplasia may be indicated. Endoscopic approach is an alternative with lower mortality and morbidity rates and favorable results. Objective: To define the best option, according to literature, to treat Barrett’s Esophagus. Materials and methods: Design: Systematic review of PUBMED, EMBASE, LILACS, and Cochrane Library databases was conducted and articles of randomized, controlled studies on BE endoscopic ablative treatment were selected. The systematic review through PUBMED retrieved results with higher evidence level and available recommendation grade regarding BE ablative therapy. Nine articles on randomized, controlled studies classified as A or B according to the Oxford table were...

Background: Abdominal pain is present in the vast majority of patients with chronic pancreatitis, being frequently debilitating. Celiac plexus block (CPB) is an interventional technique that can be considered to provide a temporary pain relief. Objective: To estimate the effectiveness and safeness of endoscopic-ultrasound (EUS) comparing with percutaneous-guided CBP in patients with pancreatic pain. Methods: A systematic review of English and non-English articles using MEDLINE, EMBASE, LILACS and COCHRANE (via BVS). Study selection and data extraction: Only randomized control trials (RCT) comparing the beneficial and harmful effects of EUS and percutaneous-guided celiac plexus block for managing pancreatic pain were included. Data was extracted and analyzed on variables including pain relief and related procedure complications. Results: Two RCT met the inclusion criteria. Both studies as...
