Study Groups

Anchoring-tip EMR
AEMR, the snare tip was projected from the sheath by 1-2 mm length. Consequently, a small mucosal incision was made at proximal side of lesion. Then the snare was deployed progressively and adjusted around the lesion trying to obtain free margins.
Anchoring-tip vs. Conventional
Anchoring-tip: the snare tip was projected from the sheath by 1-2 mm length. Consequently, a small mucosal incision was made at proximal side of lesion. Then the snare was deployed progressively and adjusted around the lesion trying to obtain free margins. At the final step of both conventional and Tip-in EMR, the lesion was resected.
Conventional: After injection of normal saline solution mix, snaring was tried for polyp resection.
Conventional EMR
After injection of normal saline solution mix, snaring was tried for CEMR.
Anchoring-tip vs. Conventional
Anchoring-tip: the snare tip was projected from the sheath by 1-2 mm length. Consequently, a small mucosal incision was made at proximal side of lesion. Then the snare was deployed progressively and adjusted around the lesion trying to obtain free margins. At the final step of both conventional and Tip-in EMR, the lesion was resected.
Conventional: After injection of normal saline solution mix, snaring was tried for polyp resection.
