 note = {Endoscopic examination was performed on 287 patients of chronic liver diseases. Esophageal varices were detected in 213 patients and classified according to the criteria proposed by Japanese Comnities on Portal Hypertension (1979). Variceal bleeding occurred in 1.9% of white varix and 9.3% of blue varix. There was not a statistical difference between them (P<0.05). Bleeding was significantly more frequent in the patients associated with R-Csign (particularly, hematocystic spot, cherry-red spot and red wale marking). Bleeding was found in 2.9% of varices in inferior location (Li), 29.6% in medial location (Lm) and 42.1% in superior location (Ls). There were statistical differences between Li and Lm and Li and Ls (p<0.01). Bleeding occurred in 3.6% of string-like venous dilatation (F1), 19.8% of medium sized varices (F2) and 45.5% of large or nodular varices (F3). There were statistical differences among them, respectively (p<0.01). On the other hand, we investigated the natural course of the esophageal varices in 93 patients using this criteria. Worsening in endoscopical findings was seen in 57 patients (61.3%) and 36 patients remained in the same endoscopical findings. This worsening was observed along with time, in 82.5% of the petients who had been followed up over a period of two years. Bleeding patients took shorter period in worsening of endoscopical findings than that of no bleeding one. Variceal bleeding were found in 24.6% of worsening group and 16.7% of remained group, there was not a statistical difference between them.},
