Preoperative assessment of frailty predicts age‐related events after hepatic resection: a prospective multicenter study

Age‐related events, such as cardiopulmonary complications, delirium, transfer to a rehabilitation facility, and dependency are a major problem after hepatic resection in the elderly. This prospective multicenter study aimed to preoperatively evaluate frailty in the elderly according to a phenotypic frail index, named the “Kihon Checklist (KCL),” to predict “age‐related events” after hepatic resection.
