Endoscopic Submucosal Dissection for Gastrointestinal Neoplasms
Endoscopic mucosal resection (EMR) is widely accepted as a minimally invasive treatment for
GI neoplasms.However, one disadvantage of EMR is that lesions larger than 2 cm in diameter
must be removed in pieces, which may result in a high recurrence rate of residual tumor
tissue. In addition, in most patients, pathological assessment cannot be conducted after the
procedure. ESD can overcome the disadvantages of EMR. However, it is difficult to perform
ESD for GI neoplasms because of the high rate of complications.
