Postresection liver failure is generally defined by serum total bilirubin greater than 3mg/dL and prothrombin time of less than 50% of normal (INR >1.7). Pathophysiology of postresection liver failure is not yet well known. However, sepsis after liver resection, small-for-size syndrome (SFSS), and ischemia/reperfusion injury are known to have important roles in persistant liver injury after resection.
