I was told at inquest that, at the time of Ms Green’s death, there were only 6 hyperbaric oxygen chambers in the country and none in London. I heard that considerable time was spent by staff at the Whittington Hospital trying to locate their nearest unit.
There had been a unit in East London at Whipps Cross Hospital, and this appeared online to be operational. However, the staff eventually discovered that this had been decommissioned. This was when they approached the James Paget Hospital in Great Yarmouth.
I heard that, as a result of Ms Green’s death, the unit at Whipps Cross Hospital has re-opened temporarily for one year. However, Ms Green’s treating consultant anaesthetist gave evidence at inquest that she did not know this. She also told me that the Whittington still does not have a pathway for use in such situations. As a starting point, she explained that some anaesthetists are unlikely to be aware that endoscopists may not necessarily know that a perforation has occurred during the procedure, and will not have the potential for pneumocephalus in their thinking.
It seems to me that all relevant healthcare professionals should have information about the location of the nearest operational hyperbaric oxygen chamber, and I was told that the trust should have a clear pathway for anaesthetists and gastroenterologists regarding the care and transfer of patients who do not wake up after oesophageal dilatation.

Investigation and inquest
On 17 December 2025, I commenced an investigation into the death of Linda Green, aged 66 years. I concluded the inquest on 8 June 2026. I recorded a medical cause of death of: 1a hypoxic-ischaemic brain injury 1b cerebral air embolism 1c oesophageal mucosal tear complicated by pneumomediastinum following elective oesophageal balloon dilatation (21/11/25) 1d severe lymphocytic oesophagitis with stricture 2 rheumatoid arthritis
Circumstances of the death
Linda Green died as a result of a complication of medical treatment. She underwent an oesophageal balloon dilatation at 9.30am on 21 November 2025 at the Whittington Hospital in London. This lasted approximately 10 minutes. Unbeknown at the time to those treating her, the procedure caused an oesophageal perforation that resulted in a cerebral air embolism. This led to her not waking up from the anaesthetic and ultimately killed her.
The perforation and pneumocephalus were diagnosed at 1.30pm. She did not leave the hospital for transfer to a hyperbaric oxygen unit until 6pm. She died the following day at the James Paget University Hospital in Great Yarmouth.
Action should be taken
In my opinion unless action is taken to address the above concerns then there is a significant risk of future deaths and I believe that you have the power to take such action.
