About

Bettina Lieske is a leading colorectal surgeon whose research focuses on advancing minimally invasive surgical techniques for rectal cancer treatment. Her work critically evaluates the comparative effectiveness of robotic-assisted and hand-assisted laparoscopic approaches, particularly for total mesorectal excision (TME)—a technically demanding procedure central to rectal cancer management. In her landmark 2014 study, "Endowrist Versus Wrist" (18 citations), she directly compared robotic and hand-assisted laparoscopic TME, providing essential evidence on surgical outcomes, precision, and recovery benefits. Her complementary review, "Laparoscopic Resection for Rectal Cancer: What Is the Evidence?" (14 citations), synthesizes data from large-scale randomized controlled trials, establishing laparoscopic colectomy as a well-validated, minimally invasive alternative to open surgery. Through these contributions, Lieske has helped clarify the role of emerging technologies in colorectal surgery, demonstrating that patients can achieve comparable oncologic outcomes with reduced surgical trauma. Her work remains influential for surgeons and researchers seeking to optimize surgical approaches, balancing technical innovation with evidence-based practice. Lieske’s research continues to shape clinical guidelines and training in minimally invasive colorectal surgery.
