About

Takayuki Ohzeki is a surgeon specializing in minimally invasive adrenal surgery, with a particular focus on robot-assisted techniques for complex adrenal pathologies. His key research areas include the surgical management of giant adrenal tumors and adrenal cysts, where he has pioneered the application of robotic platforms to address these challenging cases. Ohzeki’s major contributions center on demonstrating the feasibility and safety of robot-assisted adrenalectomy for large adrenal masses—tumors and cysts exceeding 6 cm in diameter—which have traditionally required open surgery due to their size and risk of complications. His work on giant adrenal pseudocysts, published in 2023 and cited 5 times, provides critical guidance on surgical indications and technique for these rare, often asymptomatic lesions. Additionally, his initial experience paper on robot-assisted adrenalectomy for giant tumors (2 citations) offers early evidence that robotic approaches can achieve favorable outcomes in this high-risk population. Through these studies, Ohzeki has advanced the field by expanding the boundaries of minimally invasive adrenal surgery, offering patients with large adrenal pathologies a less invasive alternative with potentially reduced morbidity.
