How Does Histology Help in Diagnosing GI Disturbances?
Histological analysis involves examining tissue samples, usually obtained through a biopsy, to identify abnormalities. Special staining techniques, such as Hematoxylin and Eosin (H&E) staining, highlight cellular structures and reveal changes indicative of disease. For instance, in conditions like gastritis, histology can show inflammation of the gastric mucosa, while in celiac disease, it can reveal villous atrophy in the small intestine.
