Dr Ralphs performed 2 oesophageal dilatations over a few months and the results have been excellent. I was told a few horror stories about the procedure by friends and family but these couldn’t be further from the truth. Dr Ralphs and the team at Oaks do a great job of reducing the anxiety around such a procedure.
