Randomized controlled trial of hemostatic powder versus endoscopic clipping for non-variceal upper gastrointestinal bleeding.

Background And Aims: Despite advances in pharmacological and endoscopic management of non-variceal upper gastrointestinal bleeding (NVUGIB), mortality is still relevant. TC-325 (Hemospray-Cook Medical) is a mineral powder with adsorptive properties, designed for endoscopic hemostasis. There are still no comparative trials studying this new hemostatic modality.

EUS-FNA versus ERCP for tissue diagnosis of suspect malignant biliary strictures: a prospective comparative study.

Background And Study Aims:  Biliary strictures are frequently a challenging clinical scenario and the anatomopathological diagnosis is essential in the therapeutic management, whether for curative or palliative purposes. The acquisition of specimens is necessary since many benign diseases mimic biliopancreatic neoplasms. Endscopic retrograde cholangiopancreatography (ERCP) is the traditionally used method despite the low sensitivity of biliary brush cytology and forceps biopsy.

Endoscopic versus surgical treatment of ampullary adenomas: a systematic review and meta-analysis.

The aim of this study is to address the outcomes of endoscopic resection compared with surgery in the treatment of ampullary adenomas. A systematic review and meta-analysis were performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. For this purpose, the Medline, Embase, Cochrane, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Scopus and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases were scanned.

Endoscopic stenting for inoperable malignant biliary obstruction: A systematic review and meta-analysis.

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 re-intervention rates; and secondarily costs, survival, and patency time.

Endoscopic hemostasis for peptic ulcer bleeding: systematic review and meta-analyses of randomized controlled trials.

Background: Peptic ulcer represents the most common cause of upper gastrointestinal bleeding. Endoscopic therapy can reduce the risks of rebleeding, continued bleeding, need for surgery, and mortality. The objective of this review is to compare the different modalities of endoscopic therapy.
