Abstract

There are no endoscopic features that distinguish intestinal metaplasia of the cardia (CIM) from the normal cardia. Biopsy specimens are therefore randomly obtained from normal-appearing mucosa with significant potential sampling errors. Enhanced magnification endoscopy involves the combined use of magnification endoscopy with acetic acid instillation. This study assessed the value of enhanced magnification endoscopy in detecting CIM. Patients undergoing elective upper endoscopy were invited to participate in the study. Patients were included if the squamocolumnar junction and the esophagogastric junction were judged to be at the same level. Enhanced magnification endoscopy was performed with 3% acetic acid instillation. Standard endoscopy was followed by magnification endoscopy and repeated after acetic acid spraying. Surface patterns were characterized before and after acetic acid spraying. The observed surface patterns were compared with histological results obtained from a single targeted biopsy specimen of each pattern. The overall prevalence of CIM was 34.8% (86/247 patients). After excluding 52 patients because of endoscopic evidence of Barrett's esophagus, 195 patients were eligible for participation in the study. In th...Continue Reading
