¹Location, Endoscopic submucosal dissection (ESD) quality (en bloc or fractional dissection rate), curability (curative or noncurative dissection rate), and complications of bleeding and perforation calculated with respect to the total number of 175 treated lesions.

²Size of dissected specimen measured only in endoscopically resected cases (n = 174).

³Number of ESD sessions (total n = 172) associated with aspiration pneumonitis. ESD: Endoscopic submucosal dissection.
