Conversion from vertical to tangential view using the anchor traction method in colorectal endoscopic submucosal dissection

Key Points

To evaluate the effectiveness of the anchor traction method in converting lesion orientation during colorectal endoscopic submucosal dissection.
Utilized anchor traction method on a 20 mm IIa lesion in the ascending colon.
Converted lesion’s orientation to a tangential angle for easier dissection.
Performed pathological analysis post-dissection.
Conversion of lesion orientation to tangential angle improved dissection safety.
Pathological analysis showed high grade dysplasia with negative margins.

Abstract

Video 1 An useful method for lesions that are vertically confronted with the endoscope. Fig. 1 The lesion was a 20 mm IIa lesion at the ascending colon. Fig. 2 The anchor traction method converted the lesion's orientation to a tangential angle, resulting in easier and safer submucosal dissection. Fig. 3 Pathological analysis revealed that the lesion was a 22 15 mm high grade dysplasia with negative margins.
