Jan Henderson was operated on in Auckland in 2016 for acromelagy, a hormonal disorder in which the pituitary gland produces too much growth hormone.
Crucially, an MRI scan performed before her surgery mistakenly led clinicians to decide Ms Henderson had a tumour on the left side of her pituitary, when in fact it was on the right.
On the strength of that misinterpretation, Ms Henderson underwent surgery, and her doctor performed major surgery on the wrong side of her gland.
Eleven months later, during a conversation with a lawyer, Ms Henderson realised - to her horror - that her doctor had blundered during the procedure.
‘‘After the operation the surgeon said to me that he hadn’t seen what he expected to see. I said what was that, and he said ‘white bits of fluffy tumour’, but he took out a third of my pituitary anyway.’’
The ACC review decision said that Ms Henderson’s consent form contained no reference to left-side surgery or right-side surgery and Ms Henderson’s evidence was that she signed that thinking she was having right-side surgery.
The reviewer said Ms Henderson had been an active, engaged and interested patient, and her recollection of events, dates and times had consistently proven to be correct.
‘‘I have sufficient experience in communications with Ms Henderson to know she has a sound understanding of her medical condition and an almost encyclopedic, albeit often too detailed, ability to reference reports, the substance of her multiple MRI scans, referrals, consultations and treatments over a period of some 10 years.’’
Today, Ms Henderson remains on medication, has to have an MRI annually to monitor her tumour, and suffers other side effects from the unnecessary operation.
‘‘I’m not great, it has impacted on me severely, but I’m alive.’’
Ms Henderson said she wanted to tell her story to let people know that they could take on ACC and win, and to warn them to be actively involved in their healthcare so that they could recognise if a mistake had, or could be, made.
‘‘People need to be aware that when you are going through this type of thing you believe what is going on around you, you believe the medical fraternity, and I have been burnt so many times now.’’
As well as her claim against ACC, Ms Henderson lodged a complaint with the Health and Disability Commissioner.
That was rejected, but Ms Henderson plans to lodge her complaint again following the finding of the review of her ACC claim.
‘‘I want them to look at it again, if for nothing else than I feel I’m entitled to an apology.’’
Ms Henderson hoped to lodge a retrospective claim with ACC for the permanent damage it now accepts she suffered, and for unpaid leave and other costs she incurred for follow-up surgery.
‘‘At the end of the day, while it was good to win there was no joy in it,’’ she said.
‘‘It has taken a long time, and I’m still very traumatised by what happened.’’
