Prognostic factors for ESD of early gastric cancers: a systematic review and meta-analysis.

Gastric neoplasms are one of the leading types of cancer in the world and early detection is essential to improve prognosis. Endoscopy is the gold-standard diagnostic procedure and allows adequate treatment in selected cases. Endoscopic submucosal dissection (ESD) has been reported to safely address most early gastric cancers (EGCs), with high curability rates.

Surveillance in inflammatory bowel disease: is chromoendoscopy the only way to go? A systematic review and meta-analysis of randomized clinical trials.

Ulcerative colitis (UC) and Crohn's disease (CD) have higher risk of colorectal cancer (CRC). Guidelines recommend dysplasia surveillance with dye-spraying chromoendoscopy (DCE). The aim of this systematic review and meta-analysis was to review all randomized clinical trials (RCTs) available and compare the efficacy of different endoscopic methods of surveillance for dysplasia in patients with UC and CD.

Adverse events after biliary sphincterotomy: Does the electric current mode make a difference? A systematic review and meta-analysis of randomized controlled trials.

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.
