The class of proton pump inhibitor (PPI) medications such as omeprazole has proven extremely effective in the treatment and prevention of gastric and duodenal ulcers. Although the FDA approval for PPI therapy is limited to 6-8 weeks, many individuals remain on these agents for years, and human studies have suggested that long-term use of a PPI can result in enterochromaffin-like (ECL) cell hyperplasia, as well as being associated with the development of fundic-gland polyps of the stomach. These findings raise the concern of the possibility that long-term use of PPIs may predispose to the development of neuroendocrine tumors in patients. The investigators aim to examine clinical parameters, including history of PPI use and fasting gastrin levels, as well as histologic characteristics (particularly the presence of ECL-cell hyperplasia) of patients found to have fundic gland polyps during endoscopy. The investigators hypothesize that there is a correlation between fundic gland polyps of the stomach and the use of proton pump inhibiter medications.

Discrete tissue masses that protrude into the lumen of the COLON. These POLYPS are connected to the wall of the colon either by a stalk, pedunculus, or by a broad base.
Focal accumulations of EDEMA fluid in the NASAL MUCOSA accompanied by HYPERPLASIA of the associated submucosal connective tissue. Polyps may be NEOPLASMS, foci of INFLAMMATION, degenerative lesions, or malformations.
The growth of INTESTINAL POLYPS. Growth processes include neoplastic (ADENOMA and CARCINOMA) and non-neoplastic (hyperplastic, mucosal, inflammatory, and other polyps).
Discrete abnormal tissue masses that protrude into the lumen of the DIGESTIVE TRACT or the RESPIRATORY TRACT. Polyps can be spheroidal, hemispheroidal, or irregular mound-shaped structures attached to the MUCOUS MEMBRANE of the lumen wall either by a stalk, pedunculus, or by a broad base.
A sebaceous gland that, in some animals, acts as an accessory to the lacrimal gland. The harderian gland excretes fluid that facilitates movement of the third eyelid.
