About

Toru Utsunomiya is a leading figure in the advancement of minimally invasive liver surgery (MILS), with a focused expertise in refining postoperative protocols to enhance patient recovery. His major contribution lies in challenging long-standing surgical dogma through rigorous clinical investigation. Utsunomiya is best known for his work on the necessity of routine abdominal drainage following laparoscopic and robotic hepatectomy. He designed and authored the protocol for a landmark multicenter randomized controlled trial to evaluate the feasibility and safety of omitting this traditional practice, a study that has already garnered early attention in the surgical community. By questioning established norms, his research aims to reduce patient discomfort, shorten hospital stays, and lower infection risks without compromising surgical outcomes. This work places him at the forefront of evidence-based innovation in hepatobiliary surgery, directly impacting the evolution of enhanced recovery after surgery (ERAS) protocols for complex liver procedures. His dedication to high-quality, prospective clinical research is shaping the next generation of standards in MILS.
