CRP and hematologic disorder: However, the multivariable analysis showed that the presence of hematological disorders (hazards ratio [HR], 9.13; 95% confidence interval [CI], 3.79–22.02, p < 0.001), higher CRP levels before the initial surgery (HR, 1.01; 95% CI, 1.01–1.02, p < 0.001), and a shorter specimen resection length were risk factors for reoperation (HR, 0.96; 95% CI, 0.93–0.99, p = 0.011).
