Compared with the non-ischemia group, the group with intestinal ischemia presented more significant peritoneal irritation signs and CT signs (increased unenhanced bowel-wall attenuation, bowel-wall thickening, mesenteric haziness, peritoneal fluid, and whirl sign), a higher D-dimer level, a higher neutrophil-lymphocyte ratio (NLR), a higher PLR, and a higher C-reactive protein level (all P<0.05) (Table 1). The gene discussed is CRP; the disease is ischemia.
