Barrett ad treatment low grade dysplasia

Seth A Gross, Michael S Smith, Vivek Kaul
Background: Barrett's esophagus (BE) and esophageal dysplasia (ED) are frequently missed during screening and surveillance esophagoscopy because of sampling error associated with four-quadrant random forceps biopsy (FB). Aim: The aim of this article is to determine if wide-area transepithelial sampling with three-dimensional computer-assisted analysis (WATS) used adjunctively with FB can increase the detection of BE and ED. Methods: In this multicenter prospective trial, patients screened for suspected BE and those with known BE undergoing surveillance were enrolled...

BACKGROUND: Endoscopic surveillance for non-dysplastic Barrett's esophagus (BE) is contentious and its cost effectiveness unclear. OBJECTIVE: To perform an economic analysis of endoscopic surveillance strategies. DESIGN: Cost-utility analysis by using a simulation Markov model to synthesize evidence from large epidemiologic studies and clinical data for surveillance, based on international guidelines, applied in a coordinator-managed surveillance program...

The incidence of gastroesophageal reflux disease (GERD) and esophageal columnar metaplasia is rising worldwide. Both mechanical and functional factors perturb the double sphincter barrier at the esophagogastric junction (EGJ). Discovery of the acid pocket is fundamental in understanding postprandial acid reflux. Adding impedencemetry to pH measurements allows detection of non-acid or weakly acidic reflux. Histologic and endoscopic injury of the squamous mucosa rises from dilation of the intercellular spaces, papillary extension, accentuated intrapapillary looping, red streaks, erosive tissue loss, etc...
