1.1 Evidence on the safety and efficacy of balloon cryoablation for squamous dysplasia of the oesophagus is inadequate in quantity and quality. Therefore, this procedure should only be used in the context of research. This could be in the form of randomised controlled trials or published registry data. Find out what only in research means on the NICE interventional procedures guidance page.
1.2 Patient selection should be done by clinicians experienced in managing squamous dysplasia of the oesophagus.
1.3 Further research should report patient selection, longer-term follow up and complications, including oesophageal stricture.
