About

Dr. Seung-Young Oh is a leading surgical oncologist whose work centers on refining gastric cancer treatment through minimally invasive and function-preserving techniques. His most influential contribution is his research on pylorus-preserving gastrectomy (PPG) for early gastric cancer, a landmark study with 76 citations that has helped establish PPG as a standard, quality-of-life-improving alternative to traditional gastrectomy. Dr. Oh further demonstrated the critical impact of endoscopic screening on gastric cancer management, showing in a highly cited 2014 study (71 citations) how early detection via screening dramatically improves treatment outcomes and shifts disease stage at diagnosis. He has also advanced the frontier of robotic surgery, publishing a feasibility study on using an articulating bipolar vessel sealer in da Vinci robot-assisted gastrectomy, providing essential technical guidance for safer, more precise operations. Beyond gastric cancer, his research extends to prostate cancer, where a recent population-based study (2023) examined the prognostic implications of urinary tract infections following definitive treatments. With over 165 total citations, Dr. Oh’s work directly shapes clinical guidelines and surgical practice, offering patients better oncologic outcomes and enhanced postoperative quality of life.
