About

Xu Guan is a leading colorectal surgeon whose research is reshaping perioperative care and minimally invasive surgical techniques. His work centers on optimizing surgical protocols for colorectal cancer, with a particular focus on bowel preparation standardization and robotic surgery innovations. Guan’s landmark nationwide survey on preoperative bowel preparation practices, published in 2018 with 14 citations, revealed critical variability among Chinese surgeons and provided evidence-based recommendations that have influenced national guidelines. More recently, his 2024 multicenter study comparing robotic natural orifice specimen extraction surgery (NOSES) to traditional transabdominal approaches for early-stage rectal cancer has garnered attention for demonstrating superior recovery outcomes with comparable oncologic safety. This work, with 4 citations already, positions Guan at the forefront of advancing scarless surgery. His research bridges the gap between clinical evidence and surgical practice, directly impacting patient recovery and quality of life. As a key figure in the Chinese Society of Colorectal Cancer, Guan continues to drive multicenter collaborations that set new standards for colorectal surgery, making him an influential voice in both national and international surgical communities.
