Pre-hepatectomy type IV collagen 7S predicts post-hepatectomy liver failure and recovery

Figure 3 Postoperative time to recovery of liver function in patients who had jaundice preoperatively in our study. Time to recovery was defined as return to Child-Pugh class A and return of serum total bilirubin and albumin levels to < 2 mg/dL and > 2.8 mg/dL, respectively. It was compared between patients with serum preoperative type IV collagen 7S > 6 ng/mL (n = 16) and those with serum preoperative type IV collagen 7S ≤ 6 ng/mL (n = 5). For the long-term postoperative recovery of liver function as well, the time to recovery was significantly shorter in the group with preoperative type IV collagen 7S ≤ 6 ng/mL than in the group with preoperative type IV collagen 7S > 6 ng/mL. The time to recovery of Alb tended to be shorter in the group with preoperative type IV collagen 7S ≤6 ng/mL than in the group with preoperative type IV collagen > 6 ng/mL; however, the difference was not statistically significant. TB: Total bilirubin; Alb: Albumin.
