Thickness of Brunner's glands and its clinical significance in peptic ulcer diseases.
The thickness of Brunner's glands was measured using an ocular micrometer in 297 cases of surgically resected peptic ulcer and in 120 autopsy cases (control group). The mean maximum thickness of Brunner's glands in the control group was 1.55 +/- 0.37mm (mean +/- SD) and no difference in thickness was noted for each decade of age. The mean maximum thickness of Brunner's glands in patients with gastric ulcer, duodenal ulcer and gastroduodenal ulcer was 2.34 +/- 1.06, 3.18 +/- 1.07 and 3.24 +/- 1.05mm, respectively. When an ulcer is within the duodenum, Brunner's glands near the ulcer were thicker than those contralateral to it. In patients with gastric ulcer, Brunner's glands were the thickest in the pyloric ulcer group and negative correlation was noted between the thickness of Brunner's glands and the distance to the ulcer from the pyloric ring. Since gastric acidity is supposed to be lower when an ulcer is located more proximally, these results suggest that Brunner's glands become hyperplastic not only with the presence of an ulcer in the duodenum but also by acid hypersecretion of the stomach.
