About

Angelo Alessandro Marra is a pioneering colorectal surgeon whose research focuses on advancing robotic-assisted pelvic floor surgery, particularly for rectal prolapse and associated pelvic floor disorders. His major contributions center on optimizing the cost-effectiveness and standardization of robotic ventral mesh rectopexy (RVMR), a minimally invasive technique that corrects rectal prolapse while preserving pelvic anatomy. Marra’s work demonstrates that robotic surgery for rectal prolapse can be performed safely with reduced expenses, challenging the perception that robotic approaches are prohibitively costly. His 2023 study on technical modifications for cost optimization, with 6 citations, provides a practical framework for institutions adopting robotic techniques. Notably, Marra led the 2025 Delphi consensus on RVMR, a landmark effort to establish standardized guidelines for preoperative evaluation, patient selection, and procedural techniques—addressing critical variability in the field. This consensus, already cited 3 times, positions him as a key figure in shaping future practice. His 2021 video vignette on modified RVMR further showcases his innovative surgical approach. With a growing citation impact, Marra’s research bridges surgical innovation and economic feasibility, making robotic pelvic floor surgery more accessible and reproducible for surgeons worldwide.
