| pubmed-article:307743 | pubmed:abstractText | The origin of bleeding in 54 patients was determined by fibroscopy in 36 cases. In 29 (80%) it was due to oesophageal varices. Such ulceration of oesophageal varices is the chief cause of bleeding (80% of cases). It is most grave when there is abundant and persistent haemorrhage in an individual aged less than 55, in particular male, and with signs of severe hepatic insufficiency. | lld:pubmed |
