Since the advent of Peroral Endoscopic Myotomy (POEMS), tunneling technique has become
a popular way of performing ESD.
After initial distal dissection, proximal end of the lesion is approached,creating
a submucosal tunnel. The tunnel wall is then collapsed to remove the lesion. Data
from a tertiary referral centre is depicted in [Table 1], demonstrating tunneling technique is a safe, effective and efficient way to perform
ESD, specially in Western settings.
