This X-ray investigation usually clearly demonstrates the extent of the hernia, and how the stomach and oesophagus are being impacted by it.
Sometimes, but not always, it is useful to undertake oesophageal physiology studies as this can help with planning the surgery. A CT scan may also be performed to rule out any other conditions can cause similar symptoms.
I just want to say a huge BIG thank you to for doing my hiatus hernia operation – I feel like a new person and am so grateful for all your care and consideration that has made such a difference for me.
