Abstract

<p>Sleeve gastrectomy was covered by Japan's national health insurance as bariatric surgery for morbid obesity in 2014. There are a few cases of gastric bypass surgery, which is a different procedure. Given that the current incidence of gastric cancer in Japan is higher than that in the EU and US, the difficulty that gastric bypass surgery presents in examining the bypassed stomach necessitates a cautious approach to the indication of gastric bypass surgery in Japan.

When a patient develops anemia and abdominal symptoms after bariatric surgery, the surgical procedure should be considered in the inspection.</p>
