About

Marc Abou Assali is a leading investigator in the field of minimally invasive surgery, with a focused expertise in the comparative effectiveness of robotic versus laparoscopic techniques for gallbladder disease. His major contributions center on large-scale, real-world evidence generation, challenging the rapid clinical adoption of robotic surgery with rigorous outcomes data. Dr. Abou Assali is the principal architect of the ROBOtic Care Outcomes Project (ROBOCOP), a landmark research initiative that has produced two of his most cited works. His 2024 study on emergent acute gallbladder pathology (12 citations) was among the first to analyze a vast national database, revealing critical differences in conversion rates and complications between robotic and laparoscopic cholecystectomies in emergency settings. This work was quickly followed by his 2025 analysis of elective procedures (2 citations), further solidifying his reputation for high-impact, practice-informing research. By systematically evaluating safety and efficacy, Dr. Abou Assali provides surgeons and policymakers with the evidence needed to navigate the evolving landscape of surgical robotics, making him a pivotal voice in modern surgical outcomes research.
