The blood picture of a patient with intestinal obstruction is not necessarily high. Blood picture is a colloquial term, clinically it is strictly called the white blood cell count and neutrophil ratio in routine blood examination, if the white blood cell count or neutrophil ratio is elevated represents bacterial infection. In contrast, intestinal obstruction clinically includes complete intestinal obstruction and incomplete intestinal obstruction, and the vast majority is adhesive intestinal obstruction. Further development of intestinal lumen expansion is obvious, containing a large number of bacteria can be infected through the permeable wall, thus causing the body’s leukocyte and neutrophil counts to rise. Therefore, intestinal obstruction does not necessarily have a high blood count, especially in early incomplete intestinal obstruction, which does not cause bacterial transmural infection in the intestinal lumen, and the white blood cell count can be normal.
