Moreover, lab analysis revealed significantly elevated CRP level in both peritoneal fluid (p = 0.033) and serum samples (p = 0.001) of patients with an anastomotic leakage compared with patients without an anastomotic leakage (median peritoneal fluid CRP expression 74.6 mg/dl in AL patients vs. median peritoneal fluid CRP expression in non-AL patients 53.6 mg/dl) (median serum CRP expression in AL patients 185.7 mg/dl vs. median serum CRP expression in non-AL patients 112.8 mg/dl) (Fig. 3). The gene discussed is CRP; the disease is axial length measurement.
