Clinical and Endoscopic Differences Between Patients With Barrett's Esophagus With and Without Dysplasia/Adenocarcinoma.

Introduction: Barrett's esophagus (BE) is the main precursor of esophageal adenocarcinoma (EAC). This study aimed to identify the risk factors associated with BE progression to dysplasia or EAC in a Latin population.

Methods: The study is a retrospective analysis of a single-center cohort of patients with BE, evaluated from 2002 to 2012.

CD138 immunohistochemistry identifies more plasma cells compared with hematoxylin and eosin staining in autoimmune hepatitis. An observational study.

Introduction: Autoimmune hepatitis (AIH) is associated with periportal infiltration by plasma cells. Plasma cell detection is routinely performed through hematoxylin and eosin (H&E) staining. The present study aimed to assess the utility of CD138, an immunohistochemical plasma cell marker, in the evaluation of AIH.

Can topical epinephrine application to the papilla prevent pancreatitis after endoscopic retrograde cholangiopancreatography? Results from a double blind, multicentre, placebo controlled, randomised clinical trial.

Background And Study Aims: Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is a complication associated with important morbidity, occasional mortality and high costs. Preventive strategies are suboptimal as PEP continues to affect 4% to 9% of patients. Spraying epinephrine on the papilla may decrease oedema and prevent PEP.

Utility of endoscopic ultrasound in idiopathic acute recurrent pancreatitis.

Unlabelled: Idiopathic acute recurrent pancreatitis (IARP) is defined as at least two episodes of acute pancreatitis with the complete or near-complete resolution of symptoms and signs of pancreatitis between episodes, without an identified cause. There is a paucity of information about the usefulness of endoscopic ultrasound (EUS) in IARP.

Objectives: To determine the diagnostic yield of EUS in IARP.

Bleeding from gastrointestinal ectopic varices is not associated with haemorrhage from oesophageal or gastric varices.

Introduction: Ectopic varices are those that appear in a different region of the gastroesophageal junction. Bleeding from ectopic varices is rare but is usually massive and deadly.

Aim: To identify the possible factors that cause bleeding from ectopic varices in patients with portal hypertension.
