1967, 1,[80][81][82] 3leeding peptic ulcer accounts for 80 to 85 ! ; ; of hospital admissions for gastrointestinal haemorrhage (Tanner, 1954 Avery Jones, 1957Aird, 1957). Improved supportive therapy and greater co-operation between physicians and surgeons have lowered the mortality in this condition. Mortality is influenced by the age of the patient, the severity of the bleeding, and the site of the ulcer. Patients over the age of 50 who continue to bleed may die unless treated surgically (Avery Jones, 1947). Chinn, Littell, Badger, and Beams (1956) pyloroplasty after dealing with a duodenal ulcer was so unsatisfactory that a gastroenterostomy was added.The mortality from operations is shown in Table I, and there is an apparent bias in favour of conservative surgery except in the treatment of erosions. One of the criticisms of conservative surgery has been a high incidence of postoperative bleeding. This is examined in Table II
