[Prevalence of periampullary diverticular, its association with choledocolithiasis and technical sucess with ERCP].

Background: Periampullary diverticula (DP) are thought to be associated with bile duct stones; they may influence the index of success or failure at endoscopic retrograde cholangiopancreatography (CPE) and may increase the risk of its complications.

Aim: Assess the association between DP with bile duct stones and its contribution with the technical success at CPE.

Methods: Two hundred and forty five consecutive patients who were undergoing CPE between April 1st and September 23th were prospectively entered into a database.

[Appropriate use of diagnostic esophagogastroduodenoscopy and its relation with positive results].

[Association between symptomatic gastroesophageal reflux and Barrett's esophagus].

Background Data: Barrett esophagus is a proximal displacement of the squamocolumnar junction relative to the gastroesophageal junction with intestinal metaplasia, it has been linked to gastroesophageal reflux disease. However, it has been observed in individuals without gastroesophageal reflux symptoms, with prevalence up to 25% in 50 years older men.

Objective: Assess the association between symptomatic gastroesophageal reflux and Barrett's esophagus.
