About
William C. Chapman is a leading figure in hepatobiliary and pancreatic surgery, with a research focus on establishing objective benchmarks for surgical outcomes and advancing technical skills assessment in minimally invasive procedures. His landmark 2023 study, cited 13 times, introduced novel benchmark values for open major anatomic liver resection in non-cirrhotic patients—a critical reference point for standardizing outcomes across centers worldwide. This work directly addresses the historical lack of comparative data for major hepatectomies, enabling more rigorous quality improvement and inter-institutional comparisons. Chapman also spearheaded the development of the Anastomosis Objective Structured Assessment of Technical Skill (A-OSATS), a validated tool for evaluating robotic ileocolic anastomosis performance. His contributions bridge the gap between surgical technique and measurable competency, offering residents and educators a structured pathway to mastery. By combining large-scale outcome benchmarking with granular skill assessment, Chapman’s research empowers surgeons to achieve reproducible excellence in complex abdominal surgery.
