The origin of the progenitor cell for Barrett's esophagus remains a major unsolved mystery. Understanding the source of this progenitor may improve strategies to prevent the development of esophageal adenocarcinoma. Esophageal submucosal glands (ESMGs) and ducts may serve as a potential source of progenitor cells that respond to esophageal injury. Through the use of human histologic and molecul...
BACKGROUND Adenocarcinomas located near the gastroesophageal junction have unclear etiology and are difficult to classify. We used DNA methylation analysis to identify subtype-specific markers and new subgroups of gastroesophageal adenocarcinomas, and studied their association with epidemiological risk factors and clinical outcomes. METHODOLOGY/PRINCIPAL FINDINGS We used logistic regression m...
OBJECTIVE To clarify the important clinicopathological factors affecting the early recurrence of adenocarcinoma of esophagogastric junction (AEG). METHODS We retrospectively reviewed the clinical data of 147 AEG patients who underwent R0 resection during the period from December 1995 to December 2007. Risk factors asssociated with the early recurrence were analyzed by χ(2) test and logistic r...
At the gastroesophageal junction, most vertebrates possess a functional lower esophageal sphincter (LES) which may serve to regulate the passage of liquids and food into the stomach and prevent the reflux of gastric contents into the esophagus. Snakes seemingly lack an LES and consume meals large enough to extend anteriorly from the stomach into the esophagus thereby providing the opportunity f...
INTRODUCTION We studied the inter-relationships of endoscopic findings around the gastroesophageal junction in patients with symptomatic gastroesophageal reflux. METHODS Data were collected with regard to hiatus hernia (HH), columnar-lined esophagus (CLE), reflux esophagitis (RE) and gastroesophageal flap valve (GEFV), prospectively from 1,150 patients who underwent diagnostic upper gastroint...
