Cystic changes of gastric mucosal glands have been described mainly after gastric operations, and like intestinal metaplasia and dysplasia, they may represent a premalignant condition. Their association with gastritis raises the possibility of their being secondary to the inflammatory process. Enterogastric reflux of duodenal contents, local chronic ischemia, and inflammatory reaction as a result of gastric surgery and suture at gastroenterostomy have been considered responsible for this lesion. In 18 of 157 consecutive patients (11.5%) who underwent endoscopic gastric biopsy within a year we found cystic changes of gastric mucosal glands. Cystic changes were present in 43% of 30 patients after gastric operation for duodenal ulcer disease, within an average of 8.4 years in contrast to only 4% of patients with an intact stomach. This change is statistically significant (Z = 1.97, p < 0.05) and suggests that there is a cause-and-effect link between the operation and the development of cystic lesions. In three patients we traced the original operative specimen, and in none did we find cystic changes. All the cases were associated with chronic gastritis; mild dysplasia was found in four (22%). The cystic glands were shown (by alcian blue-periodic acid-schiff staining) to secrete neutral mucin like normal gastric glands, and unlike dysplastic glands or intestinal metaplasia where acid mucin is characteristic. Thus, our findings suggest an inflammatory cause for the cystic glandular change (reactive, hyperplastic change of glands), and suggest that it is probably not a preneoplastic state.
