Cold snare endoscopic submucosal resection
A 76-year-old lady was referred for resection of a large
(50 mm) sigmoidal sessile adenoma (Paris classification
IIb, JNET2a, Figure A).
After submucosal injection with diluted indigo carmine
and adrenaline, the lesion was resected using cold snare
piece-meal technique (Captivator 10 mm cold single
use snare, Boston). Because of a zone with presumably
residual polyp tissue, an additional resection of submucosa
was performed (Figure B, arrow). This resection turned
out to cut deeper than expected and reached as far as the
circular muscles (Figure B, arrowhead). No preventive
clips were placed. No complications occurred, there were
no immediate or late bleedings.
