Fig. 1From: Evaluation of preoperative risk factors and postoperative indicators for anastomotic leak of minimally invasive McKeown esophagectomy: a single-center retrospective analysisSerum prealbumin concentration trend on postoperative day in AL and None AL group. The concentration of prealbumin between AL group and None AL group appears to show significant difference on POD 4(t = − 2.47, P = 0.05), POD 5(t = − 2.27, P = 0.04), POD 6 (t = − 2.08, P = 0.05). The AL group has a lower concentration of prealbumin while the trends of prealbumin on postoperative day in both groups are similar. Serum prealbumin concentration cutoff value of 128 g/L on postoperative day 5 is 100.00% sensitive and 50.00% specific for detecting esophageal leaksBack to article page
