Sa1580 Argon Plasma Coagulation Compared With snare Tip Soft Coagulation in an In-Vivo Porcine Model of Endoscopic Mucosal Resection

Advantages of CAST for non-lifting adenomas

“…Other advantages of the CAST technique are the precision of the technique and the cost-effectiveness of using the same snare that is used for the resection. Whilst no difference in the depth of tissue injury between the techniques has been shown in an animal model [4], APC is anecdotally more unpredictable to apply, in addition to there being a high cost for the consumables. It is important to emphasize that the 101 non-lifting lesions described in our study were the most difficult 16 % of lesions that presented to our center over the study period and that, without CAST, they would otherwise have required surgical resection.…”

Dual-modality management of non-lifting colorectal neoplasia: CAST or ACA?

“…In addition, ACA uses argon plasma coagulation as the thermal modality. This gives a superficial [3,4] and controlled non-contact diathermy effect that rarely causes bleeding and can rapidly treat even a large area of fibrotic polyp tissue. The sequence of ablation followed by avulsion in ACA can be repeated until all polyp tissue has been "peeled away," often leaving a white visible scar below.…”
