About
Caiwen Han is a leading researcher in the field of robotic-assisted minimally invasive surgery, with a particular focus on gastrointestinal, bariatric, and urologic oncology. Their work systematically evaluates the clinical advantages of robotic platforms—especially the da Vinci system—over traditional laparoscopic approaches. Han’s most influential meta-analysis, comparing robotic-assisted versus laparoscopic cholecystectomy for benign gallbladder disease, has garnered 77 citations and helped clarify the trade-offs in operative time, cost, and recovery. Another highly cited study (52 citations) on robotic versus laparoscopic proctectomy for rectal cancer, which exclusively analyzed randomized controlled trials, provided rigorous evidence on oncologic and functional outcomes. Han has also advanced bariatric surgery through a meta-analysis on Roux-en-Y gastric bypass (42 citations) and explored postoperative care innovations, such as suprapubic tube drainage after robotic prostatectomy. Notably, Han pioneered the “3+2” robotic configuration—using three arms and two assistants—for radical gastrectomy and distal pancreatectomy, demonstrating its safety and feasibility in complex abdominal surgeries. Through high-impact systematic reviews and technical innovations, Han has shaped evidence-based practice in robotic surgery, helping surgeons optimize patient outcomes across multiple surgical disciplines.
