Abstract:
Intestinal metaplasia (IM), a precancerous precursor lesion to gastric cancer, can be subtyped as complete or incomplete, with the latter associated with a higher cancer risk. This article provides an in-depth evaluation of gross/endoscopic and microscopic findings and the role of special stains in distinguishing complete from incomplete IM. The authors also examine controversies surrounding IM subtyping, its impact on risk stratification, and its role in guiding surveillance. The article addresses the potential significance of IM subtyping in cancer progression and present arguments for its de-emphasis in clinical practice.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
