Special Issue introduction:

Endoscopic submucosal dissection (ESD) in the treatment of digestive tract tumors

has become easier and safer, which, then, has been standardized gradually all over
the world with the progress of endoscopy and equipment. There are various knives for
ESD, each with its own characteristic. In addition, new injection solutions, counter
traction devices, distal attachments, suturing devices, special endoscopes, technical
strategies, etc. have also been reported.

Furthermore, the indication of ESD for digestive tract tumors has been expanded
based on the new knowledge related to the curative histologic conditions for ESD

resected specimens using many accumulated cases until now. ESD for digestive tract
tumors is considered to be not only a therapeutic resection method but total excisional
biopsy. Basically, benign tumors are allowed to be resected in a piecemeal manner.
However, cancerous lesions should be resected en bloc with tumor-free margins to
obtain precise histologic findings for determining curability. In this aspect, ESD is an

effective and suitable therapeutic method in the treatment of digestive tract tumors.

In this special issue, we will introduce both indications of ESD and curative conditions

after ESD. Following that, we will also introduce recent innovative ESD technologies
for whole digestive tract tumors from larynx to rectum.
