RFA and Cryotherapy: Techniques and Adverse Events

RFA is a cognitive treatment for Barrett's, mainly used for low-grade dysplasia after two endoscopies and confirmed high-grade dysplasia without visible lesions. While effective in eradicating intestinal metaplasia, RFA can cause complications if misapplied. Various techniques exist, with RFA being more established than cryotherapy. Success depends on avoiding visible lesions and following a structured approach regarding ablation frequency and equipment choices.
