Abstract
Background: The advisability of endoscopic mucosal resection (EMR) for treatment of large superficial
gastric cancers has been challenged. For more reliable en bloc resection, a new method
of EMR was developed that uses a viscous substance, sodium hyaluronate, and two newly
designed devices. Methods: A large superficial gastric cancer was treated with this new EMR technique. Sodium
hyaluronate was injected into the submucosa and mucosal incisions were made with a
needle-knife. The newly developed incision forceps and flat-ended transparent hood
were used for submucosal incisions. Results: The large cancer was successfully resected endoscopically as a single piece of mucosa
6 cm in diameter without complication. Histopathologic evaluation of the specimen
confirmed that the resection was curative. Conclusions: EMR with sodium hyaluronate along with two new devices may be a reliable method for
en bloc resection of large superficial gastric lesions.
