The occurrence of postoperative infection was related to the preoperative albumin value (<25 g/L) (OR 153.118, 95% CI1.631–14372.331, p = 0.030), and there was no significant correlation with gallstone (OR 3.626, 95% CI 0.843–15.597, p = 0.084) and number of TACE (OR 0.394, 95% CI 0.154–1.005, p = 0.051) as shown in Table 2. The gene discussed is ALB; the disease is gallstones.
