There were significant differences in incidence of postoperative hyperbilirubinemia between the PIC group and the non-PIC group (34.6% vs. 3.4%, P = 0.002), as well as the approach of esophagectomy (P = 0.045), the surgical duration (469 vs. 389 min, P < 0.001), the amount of blood loss (420 vs. 300 mL, P = 0.018), the frequency of intraoperative blood transfusions (32.7% vs. 6.9%, P = 0.012) and the peak postoperative C-reactive protein level (17.3 vs. 8.6 mg/dL, P = 0.007). The gene discussed is CRP; the disease is Hyperbilirubinemia.
