About
Qiannan Sun is a surgical researcher whose work sits at the forefront of minimally invasive colorectal and gastric oncology, with a particular focus on comparing robotic-assisted and laparoscopic surgical techniques. Through rigorous systematic reviews, meta-analyses, and propensity score-matched studies, Sun has made meaningful contributions to one of surgery's most actively debated questions: when and whether robotic platforms offer genuine advantages over conventional laparoscopy. Sun's most cited work — a 2023 systematic review and meta-analysis on robotic versus laparoscopic surgery for mid-low rectal cancer (34 citations) — and a 2022 mega meta-analysis on gastrectomy for gastric cancer (27 citations) have become valuable reference points for surgeons navigating treatment decisions. Beyond these broad comparative analyses, Sun has drilled into nuanced subgroups, examining outcomes in patients with visceral obesity, varied body mass indexes, and elderly or frail populations, as well as evaluating sphincter preservation in ultra-low rectal cancer. Additional work exploring left colic artery preservation and intracorporeal versus extracorporeal anastomotic techniques reflects a commitment to refining surgical detail. Collectively accumulating over 115 citations, Sun's growing body of evidence is helping shape evidence-based practice in minimally invasive oncological surgery.
