OBJECTIVE To assess the clinical, endoscopic, and functional results in a group of patients with Barrett's esophagus undergoing classic antireflux surgery in whom dysplasia and adenocarcinoma were found at a late objective follow-up. SUMMARY BACKGROUND DATA There have been isolated reports of patients with Barrett's esophagus undergoing antireflux surgery(More)
It is well known that in patients with Barrett's esophagus (BE), even after antireflux surgery, intestinal metaplasia can progress to dysplasia or even adenocarcinoma. However, the opposite-that is regression of dysplastic changes to intestinal metaplasia after antireflux surgery-has been documented in only a few reports. The objective of this study was to(More)
OBJECTIVE The pathophysiology of gastroesophageal reflux disease (GERD) has been studied extensively in patients with long-segment Barrett's esophagus (LSBE), but few reports have explored GERD pathophysiology in patients who have short-segment Barrett's esophagus (SSBE) or intestinal metaplasia at the cardia (IMC). We aimed to compare clinical, endoscopic,(More)
Because of the evolution of the World Wide Web, the fields of intelligent agents and multi-agent systems have become a focus of interest. This intensive research has originated several frameworks, or toolkits, that are used by the researchers to develop Internet agent-based systems. Their aim is to help the designers and engineers to build complex systems(More)
