About
Masaaki Motoori is a leading figure in minimally invasive gastrointestinal surgery, with a focused expertise in robotic and laparoscopic techniques for gastric and colorectal resections. His research centers on improving surgical safety and patient outcomes, particularly by reducing severe postoperative complications. Motoori’s major contribution is the identification and validation of the pancreas-left gastric artery angle (PLA) as a critical risk indicator for pancreatic fistula following distal gastrectomy. His 2022 study demonstrated that robotic distal gastrectomy significantly reduces drain amylase values in patients with a small PLA, directly lowering fistula rates compared to standard laparoscopic approaches. This work, cited 3 times, provides surgeons with a measurable anatomical parameter to guide operative decision-making. More recently, in 2025, Motoori has advanced the field by comparing short-term clinical outcomes and cost-effectiveness of intracorporeal anastomosis using robotic versus laparoscopic staplers during robot-assisted right colon resection. His findings offer practical, evidence-based guidance for adopting robotic platforms in colorectal surgery. Through these studies, Motoori is shaping safer, more efficient surgical protocols, making him a valuable resource for researchers and clinicians seeking to optimize robotic surgery outcomes.
