Fundic gland polyposis is a medical syndrome where the fundus and the body of the stomach develop many fundic gland polyps.The condition has been described both in patients with familial adenomatous polyposis (FAP) and attenuated variants (AFAP), and in patients in whom it occurs sporadically.
Long-term use of PPIs is associated with the development of benign polyps from fundic glands (which is distinct from fundic gland polyposis); these polyps do not cause cancer and resolve when PPIs are discontinued. [33] There is concern that use of PPIs may mask gastric cancers or other serious gastric problems. [33]
Gastric polyps are adenomas that are usually asymptomatic and benign, but may be the cause of dyspepsia, heartburn, bleeding from the stomach, and, rarely, gastric outlet obstruction. [ 61 ] [ 71 ] Larger polyps may have become cancerous . [ 61 ]
The H 2 receptor antagonists are a class of drugs used to block the action of histamine on parietal cells in the stomach, decreasing the production of acid by these cells. H 2 antagonists are used in the treatment of dyspepsia, although they have been surpassed in popularity by the more effective [1] proton pump inhibitors.
A derivative of timoprazole, omeprazole, was discovered in 1979, and was the first of a new class of drug that control acid secretion in the stomach, a proton pump inhibitor (PPI). [ 11 ] [ 12 ] Addition of 5-methoxy-substitution to the benzimidazole moiety of omeprazole was also made and gave the compound much more stability at neutral pH. [ 6 ]
A fundic gland polyp is a type of polyp, found in the fundus of the stomach. Fundic gland polyps are found in 0.8 to 1.9% of patients who undergo esophagogastroduodenoscopy, and are more common in middle-aged women. [2] The risk of malignancy is very low or none, when sporadic. [3]
Omeprazole is a proton-pump inhibitor (PPI) and its effectiveness is similar to that of other PPIs. [9] It can be taken by mouth or by injection into a vein . [ 1 ] [ 10 ] It is also available in the fixed-dose combination medication omeprazole/sodium bicarbonate as Zegerid [ 11 ] [ 12 ] and as Konvomep.
Lansoprazole, sold under the brand name Prevacid among others, is a medication which reduces stomach acid. [4] It is a proton pump inhibitor (PPI), used to treat peptic ulcer disease, gastroesophageal reflux disease, and Zollinger–Ellison syndrome. [5] Its effectiveness is similar to that of other PPIs. [6] It is taken by mouth. [4]
