Older abdominal pain needs a lower CT threshold

October 1, 2026

Minimal tenderness is less reassuring in older adults, so CT should remain readily considered.

PEARL OF THE DAY

In an older adult with abdominal pain, little tenderness should not by itself raise the threshold for CT.

Summary

A relatively benign abdominal examination is less reassuring in an older patient than we might like it to be.

The abdominal pain cohort reviewed this month makes that problem concrete. Older adults can present with non-specific symptoms and less sensitive abdominal tenderness despite carrying a substantial burden of acute pathology. If the examination is allowed to dominate the decision, the patients least likely to produce dramatic physical signs may be the ones in whom significant disease is missed.

That does not translate into scanning every older person with abdominal pain.

About 70% of patients aged 60 or older in the cohort underwent CT, and 38% of those scans showed an acute finding. Those figures support a low threshold for imaging, but they come from a single-centre population. Local case mix and CT yield still matter before percentages are imported directly into another service.

There is another important interpretation trap in the same study. The reported adverse-outcome composite reaches 57.6%, but that outcome combines actionable CT findings, an emergency general surgical diagnosis, admission and surgery. Admission is not synonymous with abdominal pathology requiring intervention. Quoting the composite as though more than half of older patients needed treatment for serious intra-abdominal disease would overstate what the study shows.

That distinction matters because headline numbers influence thresholds. The useful finding here is not that age alone mandates CT. It is that limited tenderness and an imprecise history should provide less reassurance when an older patient presents with abdominal pain.

The other papers in the episode reinforce the value of being precise about what an outcome actually demonstrates. Early 14-day ambulatory ECG monitoring after unexplained syncope detects more clinically significant arrhythmias than standard care, but it does not significantly reduce recurrent syncope at one year. A secondary mortality difference is interesting, but the analysis does not justify treating it as established benefit.

Both studies reward the same discipline: act on the clinical problem in front of you, but do not make the evidence say more than it does. In an older adult with unexplained abdominal pain, minimal tenderness should not be the reason CT is deferred.

Respiratory-virus vaccine evidence needs careful interpretation of population, comparator and outcome.

Adults with inherited neurometabolic disorders have diverse clinical and social needs. Childhood disease onset is not the same as childhood diagnosis, disease-specific treatments are common in this specialist cohort, and absence of formal support does not establish functional independence.

October 2026; papers of the month

Older adults with abdominal pain may have significant pathology despite limited tenderness, early ambulatory ECG monitoring detects more arrhythmias without reducing recurrent syncope, and shared video laryngoscopy can help supervisors correct accumulating technical errors during paediatric intubation.

What to change on your next shift

In an older adult with abdominal pain, avoid allowing minimal tenderness or non-specific symptoms to provide false reassurance when deciding about CT. When using research to support that decision, check what a composite outcome actually contains rather than treating admission as equivalent to actionable pathology. Review local CT yield and case mix before importing another centre’s percentages directly into practice.

Questions from today’s episodes

An 85-year-old patient presents with non-specific abdominal pain and has very little tenderness on examination. How should the relatively benign examination influence the threshold for CT?

It should provide limited reassurance. Older adults can have significant acute pathology despite little tenderness, so the evidence supports retaining a low threshold for CT rather than requiring a more dramatic examination first.

A patient has unexplained syncope after initial emergency assessment and is offered immediate 14-day ambulatory ECG monitoring. What benefit does the ASPIRED trial establish?

Early monitoring detects more clinically significant arrhythmias than standard care, 22% versus 9%. It does not significantly reduce recurrent syncope at one year, and the reported mortality difference is a secondary signal that requires caution.

A 15-month-old child develops sudden drooling and refuses drinks after a choking episode. Radiographs show a circular oesophageal object with an inner ring on the frontal view and a step-off on the lateral view. What does this represent and how should it be managed?

The appearances indicate a button battery rather than a coin. An oesophageal button battery can cause rapid caustic tissue injury and requires emergency removal.
