[Recent progress in the diagnosis of gastroesophageal varices]

Recent advances in the diagnosis of gastroesophageal varices are reviewed in this paper. Endoscopy, angiography, ultrasound, and ultrasound Doppler are now employed in the diagnosis of varices. As for endoscopic diagnosis, new criteria for the evaluation of gastroesophageal varices have been applied. Angiography is now not only used to demonstrate the varices and collateral circulations in portal hypertension but also used in the embolization therapy for large gastric varices or intractable esophageal varices. Ultrasound and color Doppler are now widely used in the diagnosis of portal hypertension because of its noninvasiveness and conveniency. Furthermore, in its use in endoscopy, varical vessels and blood flow in the wall of the esophagus and the stomach can be directly demonstrated. Recent advances in these diagnostic modalities will made it possible to diagnose gastroesophageal varices and evaluate the pathophysiology in patients with portal hypertension more precisely.
