Endoscopic and radiological appraisal of gastric varices

Of 104 patients with portal hypertension who were subjected to oesophageal variceal sclerotherapy, gastric varices were seen in 81 (78 per cent) at endoscopy and 69 (74 per cent) at splenoportography. In 50 (48 per cent) patients gastric varices were seen at the initial endoscopic examination and in 31 they developed during follow-up at intervals varying from 1 to 56 weeks. Gastric varices were seen significantly more often along the lesser curvature than in the gastric fundus and the left gastric vein was the main feeding vessel in 75 per cent of cases. Varices bled in nine of 81 patients and bleeding was seen significantly more often from fundal varices (30 per cent) than from lesser curve varices (5 per cent) (P less than 0.02). The incidence of gastric varices is high, and contrary to popular belief they are more often located along the lesser curvature of the stomach than in the gastric fundus.
