Core Tip

Core Tip: This is a retrospective observational study that employs a training group to develop a difficulty scoring system for evaluating patients with intrahepatic duct stones who are undergoing laparoscopic liver resection. By employing multiple linear regression modeling, five correlates of surgical difficulty were identified (location of stones, number of stones ≥ 3, stones located in the bile ducts of several grades, previous biliary surgery less than twice, distal bile duct atrophy). Validation with an external dataset demonstrated that the model exhibits favorable predictive performance to surgical difficulty and surgical complications.
