Therapeutic Endoscopy ESD / Luminal Resection Program 

UW Medicine Therapeutic Endoscopy Program (Yutaka Tomizawa, MD MS) offers comprehensive luminal tissue resection for patients with pre-cancer and early cancer in the digestive tract (esophagus, stomach and colon), by performing Endoscopic Submucosal Dissection (ESD).


Yutaka Tomizawa"ESD was originally developed in my home country of Japan in 1990s for treating early gastric cancer, and was subsequently adopted in the other part of digestive tract lesions in the esophagus and colon. If the indication is appropriately selected, ESD provides minimally invasive removal of pre-cancer and early cancers in the digestive tract and potentially avoids extensive surgeries.

"I completed formal digestive endoscopy training in Japan before moving to the U.S., with a focus on the endoscopic management of early gastrointestinal cancer. While in Japan, I had the privilege of working with some of the world leading expertise in advanced endoscopy and having trained with ESD.

"ESD expertise is still very limited in the Unites States and I am one of a few gastroenterologists in the West Coast who provides ESD."
