Four cases of recurrent upper gastrointestinal haemorrhage occurred in patients who had undergone gastrectomy for ulcer, being secondary to reflux oesophagitis. This cause of bleeding is poorly recognised and the exact occurrence rate can be determined by the general and routine use of fibroscopy during the haemorrhage. The diagnostic and physiopathological problems are discussed. Repositioning of the cardia with the fashioning of an effective anti-reflux mechanism invariably led to the suppression of these haemorrhages.
