Current status of robotic surgery in Japan.

Abstract

The da Vinci S surgical system (Intuitive Surgical) was approved as a medical device in 2009 by the Japanese Ministry of Health, Labour and Welfare. Robotic surgery has since been used in gastrointestinal, thoracic, gynecological, and urological surgeries. In April 2012, robotic-assisted laparoscopic radical prostatectomy (RALP) was first approved for insurance coverage. Since then, RALP has been increasingly used, with more than 3,000 RALP procedures performed by March 2013. By July 2014, 183 institutions in Japan had installed the da Vinci surgical system. Other types of robotic surgeries are not widespread because they are not covered by public health insurance. Clinical trials using robotic partial nephrectomy and robotic gastrectomy for renal and gastric cancers, respectively, have recently begun as advanced medical treatments to evaluate health insurance coverage. These procedures must be evaluated for efficacy and safety before being covered by public health insurance. Other types of robotic surgery are being evaluated in clinical studies. There are several challenges in robotic surgery, including accreditation, training, efficacy, and cost. The largest issue is the cost-benefit balance. In this review, the current situation and a prospective view of robotic surgery in Japan are discussed.
