publications

Members of the SCRS–NOSES Interest Group have contributed actively to the academic development of Natural Orifice Specimen Extraction Surgery (NOSES), demonstrating its clinical benefits, safety, and utility in colorectal practice. Through ongoing research and technical innovation, the group has helped expand the indications and refine operative techniques for NOSES. A number of publications include detailed step-by-step surgical videos, which may serve as useful instructional resources for surgeons seeking to begin or further develop their NOSES practice.
