About Me

I am a board-certified gastroenterologist who specializes in using minimally invasive endoscopic techniques to diagnosis and treat gastrointestinal cancers. I have particular expertise in performing endoscopic submucosal dissections (ESD) to safely remove gastrointestinal tumors. ESD allows patients to avoid extensive surgeries and the long recovery times they often require.

ESD was originally developed in my home country of Japan in the early 2000s. Doctors are still learning how it can be best used to help people with gastrointestinal cancers. I am one of a few gastroenterologists in the United States who have extensive experience performing ESD. I have successfully treated more than 950 people with this technique.

When I meet with patients who have an early-stage cancer, they are often worried about having to undergo a big operation. In many cases, I reassure them that we can find an option that will effectively treat their disease without drastically interfering with their life. If necessary, I will perform additional endoscopic tests to ensure that we make the best treatment decisions together.

We can also use minimally invasive techniques to help people with more-advanced cancers. For example, for people who have stomach (gastric) submucosal tumors, I can work with a surgeon to perform combined endoscopic and laparoscopic surgery.

My research involves looking for more ways to use endoscopic ultrasound (EUS) to treat pancreatobiliary cancers. I am currently working on a clinical trial with my colleagues in Japan to study how we can use EUS to deliver new medicines directly to pancreatic tumors that cannot be removed.

Clinical Trials

As home to one of the world’s top cancer research centers, Memorial Sloan Kettering is typically involved in more than 900 clinical trials at a given time. Currently, clinical trials focused on the conditions I treat are enrolling new patients.

Insurance

Most major health insurers offer plans that include MSK as one of their in-network providers. If MSK is in-network, it means all our doctors are too. Medicaid and New York State Medicare also provide benefits for care at MSK.
