Preoperative data gathering, risk stratification, and individualized recovery plans result in improved outcomes. Digital integration aids ongoing monitoring and adjustment. Those institutions using predictive analytics and EHR-associated workflows are enhancing surgical planning and patient satisfaction. This data-driven approach minimizes complications and fits with Japan‘s overall vision of precision healthcare.
Challenges in the bariatric surgery market in Japan are:
• Limited patient acceptance and cultural stigma: In contrast to increased clinical endorsement, societal attitudes toward obesity and surgery are still conservative. Surgery is considered by many patients as a last option or something to be ashamed of seeking. This restricts the level of voluntary surgical procedures. Hospitals need to practice destigmatization through counseling, media education, and alliances with community organizations. Combat against stigma is necessary in order to increase patient number and gain broader acceptance of bariatric surgery as an accepted treatment.
• Lack of trained bariatric surgeons and centers: There are few surgeons with formal bariatric training outside urban centers in Japan. This limits the availability of procedures and creates long waiting lists. Hospital systems have to spend on special training programs and inter-hospital networks.
