Brief Summary:
The purpose of this study is to develop a grading system for esophageal varices using capsule endoscopy in patients with portal hypertension and cirrhosis
Detailed Description:
Up to 35 of patients with cirrhosis will develop esophageal varices which carry with them a 1-year and 3-year bleeding rate of 33 and 41 respectively Screening for varices with a video endoscopy is limited by its cost patient compliance and the risks of sedating a patient with portal hypertension Capsule endoscopy is a novel method that may reduce the costs and increase compliance for screening
The investigators propose to screen 100 consecutive patients with advanced cirrhosis for esophageal varices A capsule endoscopy and video endoscopy will be done on the same day The varices seen on video endoscopy will be graded using a standard grading scale Both capsule and video endoscopy images will be assessed in a blinded fashion by 4 independent investigators Finally the video endoscopic images will be compared to capsule endoscopy to develop a capsule endoscopy grading system that corresponds to video endoscopy
The primary endpoint of the study will be to develop a grading system for esophageal varices using capsule endoscopy Secondary endpoints of the study include sensitivity specificity inter- and intraobserver variation of variceal grading using capsule endoscopy patient acceptance as assessed on a visual analogue scale and a cost comparison facility fees professional fees of the two screening methods
