Recurring hyperplastic gastric polyps following subtotal gastrectomy.

Mucosal polyps of the stomach are separated by histologic means into two major groups: (1) hyperplastic (or regenerative) polyps and (2) adenomas, including adenomatous polyps and villous adenoma. Hyperplastic polyps are not true neoplasms, but probably represent a reactive response to some form of mucosal injury. A little known but interesting manifestation of hyperplastic gastric polyps concerns their development, growth, and recurrence in the gastric remnant following subtotal gastrectomy. The clinical, radiologic, and pathologic findings in two cases of recurring symptomatic hyperplastic gastric polyps after subtotal gastrectomy are presented. It is proposed that reflux bile gastritis might have played an important etiologic role in the development of these recurring hyperplastic polyps.
