Duodenal ulcer and stomach polyps

It is known that diseases of the upper digestive tract may be combined. Therefore, timely diagnostics of basic and concomitant pathology as well as treatment of patients taking into account these diseases have an important practical value. In particular, until now a number of points concerning duodenal ulcer, which can be combined with gastric polyposis, are not clear. How often does duodenal ulcer disease combine with gastric polyps? Should gastric polyps be removed in such patients, given the possibility of their malignant origin, and is gastric polyp outgrowth possible in patients with duodenal ulcer disease? Is it reasonable to remove gastric polyps during the acute period of duodenal ulcer disease using endoscopic gastric polypectomy?
