Investigation and inquest
On 12 May 2025 I commenced an investigation into the death of Vivian Joan Tuddenham NOLAN, aged 84. The investigation concluded at the end of the inquest on 31 October 2025.
I recorded the following narrative conclusion:
Due to recognised complications arising from and following a diagnostic colonoscopy procedure.
Circumstances of the death
Vivian was referred to secondary care by her GP due to iron deficiency anaemia and a positive FIT test. Following review by the Gastroenterology Service, Vivian was listed for a diagnostic colonoscopy (the risks discussed as part of the consent process for the diagnostic colonoscopy included perforation and need for emergency surgery).
The diagnostic colonoscopy was performed on 31 March 2025 and following the colonoscopy, Vivian was diagnosed to have a colonic perforation. Despite medical and surgical treatment, Vivian deteriorated and sadly died on 10 May 2025.
I recorded Vivian’s medical cause of death to be the following:
1a) Hospital acquired pneumonia and Covid infection
1b) Colonic perforation
1c) Diagnostic colonoscopy procedure to investigate iron deficiency anaemia
Coroner’s concerns
1. During the course of the inquest hearing, I heard evidence from the Consultant Surgeon who performed the diagnostic colonoscopy. Their evidence included that, in their view, there ought to be a higher clinical threshold for offering diagnostic colonoscopies to patients aged over 80 given the associated, increased risks. Their evidence included that there is a higher clinical threshold in other countries for offering this diagnostic investigation to the 80+ age group.
My concern is that there is a lack of knowledge amongst, and lack of clinical guidance available to, clinicians as to the potential increased risks of diagnostic colonoscopies in the 80+ age group.
