Disability in perioperative activities of daily living is associated with worse survival outcomes following hepatic resection in patients with intrahepatic cholangiocarcinoma

Aim Intrahepatic cholangiocarcinoma (ICC) is a rare disease; however, its incidence and mortality are increasing worldwide. The rapid aging of populations around the world is leading to an increased number of patients with cancer who develop disability in activities of daily living (ADL). This study was conducted to investigate the associations of perioperative ADL with patient survival after hepatic resection for ICC. Methods We included 70 consecutive patients who underwent hepatectomy for ICC from 2010 to 2021 in the current study. Preoperative and postoperative ADL were evaluated based on the Barthel index, which yields a score of 0–100 points, with higher scores indicating greater independence. A preoperative or postoperative Barthel index score of
