Endoscopic submucosal dissection for gastric neoplasms by using a novel attachment device-a one-sided, expandable balloon.

摘要

Endoscopic submucosal dissection (ESD) has become the standard treatment for large gastric neoplasms because it allows adequate histological assessment of the depth and lateral spread of the tumor and because local recurrence after multiple-fragment resection is significantly higher than that after en bloc resection. To perform effective and safe ESD, an appropriate endoscopic view is essential; however, there are some locations in which it is difficult for the tip of the endoscope to reach the target. Some tumors are located where it is difficult to get the tip of the endoscope close to the tumor, such as the lesser curvature or anterior wall of the gastric body and lesser curvature of the angulus.
