dc.description.abstractDamage to the gastrointestinal mucosa caused by ischemia - reperfusion is a significant clinical problem associated with various physiopathological conditions. Our group has conducted various studies in patients in critical conditions and in animal models to identify early damage to the gastric mucosa under ischemia using impedance spectroscopy. It is important to perform a quantitative histopathological analysis which can be linked to changes in impedance of the gastric mucosa under conditions of ischemia and I/R. Aim. To propose a tissue lesion index which considers pathological alterations inherent to the inflammatory process and cell damage which may be directly related to changes in impedance under conditions of ischemia and I/R. Methods. The animals were randomly distributed into 4 groups: control, ischemia (30 min), and I/R (30 and 60 min). Qualitative histopathological analysis was performed; the vascular area, glandular lumen area, the number of damaged cells, and the depth of the erosion were also quantified to obtain a scale to propose a tissue lesion index (TLI). Results. Under ischemic conditions, histopathological analysis showed edema and necrosis in epithelial cells, and vascular congestion. In I/R (30 and 60 min) conditions, areas of epithelial erosion were generated. Damage was classified based on the TLI. A TLI threshold of 3 showed a predictive value of tissue lesion. Conclusion. The proposed gastric lesion index allows us to objectively quantify and classify damage to the gastric mucosa produced by I/R.es
