Core Tip

Core tip: In this study, we identified the pre-hepatectomy factor associated with both early postoperative liver failure and long-term postoperative liver function recovery. We found that preoperative type IV collagen 7S is a significant independent factor associated with both post-hepatectomy liver failure and postoperative long-term recovery of liver function. Our analysis revealed that the time required for the recovery of Child-Pugh scores and serum total bilirubin and total bilirubin levels was significantly shorter in patients with type IV collagen 7S ≤ 6 ng/mL than in patients with type IV collagen 7S > 6 ng/mL.
