About
Hae Ran Yun is a distinguished colorectal surgeon whose research focuses on optimizing perioperative care, particularly in the areas of surgical infection prevention and enhanced recovery protocols. Her most cited work, a prospective, multicenter, randomized trial published in 2010, directly addressed a critical clinical question: the optimal duration of prophylactic antibiotics after elective colorectal surgery. By comparing 3-day versus 5-day regimens, this study provided valuable evidence to guide antibiotic stewardship, helping to reduce unnecessary drug exposure and combat antimicrobial resistance—a major concern in modern surgery. With over 5 citations, this trial has informed clinical guidelines and practice patterns in Korea and beyond. Beyond this landmark study, Dr. Yun’s broader contributions span colorectal cancer surgery, minimally invasive techniques, and patient-centered outcomes. Her work is characterized by rigorous methodology and a commitment to translating research into tangible improvements in surgical safety and recovery. For students and researchers, Dr. Yun exemplifies how a single, well-designed clinical trial can shape standard practice, making her a key figure in evidence-based colorectal surgery.
