SUMMARY Clinical and radiological abnormalities in 12 patients with gastroduodenal involvement were encountered amongst 300 patients followed by one of us between 1944 and 1969. Symptoms of dyspepsia were relatively mild and obstructive symptoms when present were readily relieved by bypass surgery. The patients have been followed for a mean of 9.7 years (range 1-20); two have died of other causes but the remaining 10 are well.In 1950, Comfort, Weber, Baggenstoss, and Kiely in a report on five patients established that nonspecific granulomatous inflammation of the stomach and the duodenum was the same condition as regional enteritis affecting other parts of the small intestine. Roberts and Hamilton (1966) found that only 34 patients had been reported by 1962. By 1967, approximately 62 patients had been recorded but little information is available from the reports as to the prognosis and clinical course. This paper considers the significance of involvement of stomach and duodenum in Crohn's disease from the experience of 12 patients encountered amongst 300 followed by one of us between 1944 and 1969. Clinical MaterialThere were six men and six women, including a brother and sister.

SUMMARY Barium meal studies have shown evidence of a recurrent ulcer or of stenosis in 12 out of 24 patients with recurrent dyspepsia after vagotomy and pyloroplasty. These 12 patients have been subsequently proved to have had recurrences and all but one are now cured by further surgery. Barium meals in 12 patients show no evidence of recurrence or stenosis, and follow-up clinical studies suggest that they do not have recurrent ulcer.Radiological studies appear to have great value in the interpretation of recurrent dyspeptic symptoms after vagotomy and pyloroplasty.

The accuracy of early radiology in patients with acute gastrointestinal haemorrhage has been studied by a comparison of the radiological opinion with the established diagnosis. A full examination has proved safe and uncomplicated with a high degree of accuracy and no false-positive results.Analysis of the errors shows that the presence of residue discourages the radiologist from making the correct diagnosis, and modification of the standard bariummeal technique may be needed to overcome this difficulty.
