Steps to determine eligibility for ablative treatment Ė Steps to determine eligibility for ablative treatment
The steps to determine eligibility for ablative treatment require addressing the following questions:
The examination of the patient should try to address these questions. The setup, consumables and equipment required, patient preparation, and the steps of the examination are exactly the same as those described for VIA.
On the basis of the VIA findings, if the response to questions 1, 2, and 3 above is YES and the response to questions 4 and 5 is NO, then the patient is eligible for ablative treatment. If cryotherapy is being used, an additional question to be answered is whether the tip of the largest cryotherapy probe can adequately cover the entire transformation zone. Usually, a visual assessment can answer this question. When in doubt, apply the probe on the transformation zone and confirm.
