Gastric mucosal surface in cirrhosis evaluated by magnifying endoscopy and scanning electronic microscopy.

Abstract：

BACKGROUND AND STUDY AIMS:Gastric mucosa may have several tiny patterns in portal hypertension. In this prospective study, we used magnifying endoscopy and scanning electron microscopy (SEM) to better characterize the morphology of gastric mucosa in patients with cirrhosis, and we evaluated the diagnostic accuracy of magnifying endoscopy. PATIENTS AND METHODS:Videotapes of gastric mucosal patterns from 39 cirrhotic patients and 20 control patients were blindly evaluated by the same observer using magnifying endoscopy (magnification x 25) and conventional endoscopy. SEM was performed in 12 other patients. The basic anatomical entities of the gastric architecture on conventional endoscopy were the gastric area in control patients and the mosaic pattern in patients with cirrhosis. RESULTS:With regard to the prevalence of endoscopic patterns in the antrum, the mosaic pattern was more frequent in cirrhotic patients. In the body, the mosaic pattern, white spots, and red marks were significantly more frequent in cirrhotic patients, whereas gastric areas were more frequent in control patients. Concerning the contributions of the techniques, significantly more gastric areas were identified by magnifying endoscopy than by conventional endoscopy. However, in multivariate analysis, only conventional endoscopy with esophageal varices had significant independent diagnostic accuracy for cirrhosis, and magnifying endoscopy of mucosal signs did not add any significant information. SEM did not improve discrimination between control and cirrhotic patients. CONCLUSIONS:Magnifying endoscopy provides more details of the mucosa, thus improving the delineation of gastric mucosal morphology. However, magnifying endoscopy has little clinical value in cirrhosis since it does not improve on the accuracy of conventional endoscopy for the diagnosis of cirrhosis.
