ENDOSCOPIC ANALYSIS OF THE CASES WITH ABNORMAL DUODENAL BULB FINDINGS ON PHOTOFLUOROGRAPHY IN GASTRIC MASS SURVEY

Abstract

In 2, 878 gastric mass survey cases (over 40 year old male), abnormal duodenal bulb findings on photofluorographs were found in 8.2 per cent in total, including 4.9 per cent duodenal bulb deformity and 3.3 per cent deficient barium meal filling to bulb. Those cases were examined with panendoscope (GIF-P2) and duodenal ulcer or ulcer scar and duodenitis were found in 67.0 per cent of the deformed bulb cases and 36.6 per cent of the deficient barium filling cases. With these value the incidence of duodenal ulcer falls 4.2 per cent of total examinees. The incidence of multiple or linear duodenal ulcer of these endoscopically confirmed cases were 42.5 per cent of the ulcers found among subjects with deformed bulb and 15.4 per cent of the ulcers found subjects with deficient barium meal filling (p<0.025) and the incidence of duodenal ulcer scar of the two groups are 43.2 per cent and 69.2 per cent respectively (p<0.05) . The incidence of deformed pyloric ring confirmed endoscopically is 61.9 per cent in multiple or linear ulcer cases and 35.1 per cent in single ulcer cases (p<0.025) . These data suggest that the difference of the features of the duodenal ulcer between deformed duodenal bulb cases and deficient barium meal filling cases is due to mainly the difference of the function of the pylorus.
