About

Ker‑Kan Tan is a colorectal surgeon whose research focuses on advancing minimally invasive techniques for rectal cancer surgery, particularly through robotic‑assisted and hand‑assisted laparoscopic approaches. His most cited work, “Endowrist Versus Wrist” (2014, 18 citations), directly compares robotic‑assisted total mesorectal excision (TME) with hand‑assisted laparoscopic TME, addressing the technical challenges of this demanding procedure. In a companion review, “Laparoscopic Resection for Rectal Cancer: What Is the Evidence?” (2014, 14 citations), Tan synthesizes the growing body of evidence supporting laparoscopic colectomy for colon cancer and extends the discussion to rectal cancer, highlighting the benefits of minimally invasive approaches while maintaining oncologic outcomes comparable to open surgery. Though his citation counts are modest, these papers have helped clarify the role of emerging robotic platforms in colorectal surgery, a field where high‑quality comparative data remain scarce. Tan’s work is particularly valuable for surgeons and trainees navigating the transition from traditional laparoscopy to robotic techniques, offering practical insights into operative outcomes and patient selection. His contributions underscore the ongoing evolution of surgical oncology toward safer, less invasive treatments for rectal cancer.
