Abstract

The purpose of the present study was to document the increased leukocyte adhesiveness/aggregation (LAA) and tissue leukostasis that follow surgical trauma. We found that following major abdominal surgery, the percentage of aggregated leukocytes in the peripheral blood increased from 8.6 +/- 7 to 21.7 +/- 11.5 (p < 0.001), while the respective values for patients undergoing minor surgery were 3.7 +/- 2.4 and 19.7 +/- 7.6% (p < 0.001). The state of LAA was also determined in eight dogs after partial collectomy and four controls. A clear increment in the degree of tissue leukostasis (especially in the spleen, liver and lungs) was noted in the operated as compared to the control animals. In addition, a significant correlation was found between the state of LAA, determined in the venous (p = 0.0004) and arterial (p = 0.002) blood of these animals and the degree of tissue leukostasis. We conclude that a state of increased LAA in the peripheral blood is induced by surgical trauma and that this increased LAA correlates with tissue leukostasis.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
