Researchers reviewed 19 people with an insulinoma treated at one hospital in Taiwan between 2011 and 2025.
When grouped by their final treatment, all 13 surgical patients achieved complete remission, compared with 2 of 3 treated using EUS guided ethanol ablation and none of the 3 receiving medical treatment. Medical treatment did, however, help control hypoglycaemia.
Complete remission meant sustained normal blood glucose, no hypoglycaemia symptoms and no further treatment for at least one year.
The findings support surgery as the treatment most likely to achieve remission. EUS guided ethanol ablation may offer a less invasive option for carefully selected people who cannot undergo surgery, although incomplete treatment or recurrence remains possible.
This was a very small, retrospective study. Treatment was not randomly assigned, some patients received more than one treatment and only three people were included in each non surgical group. The percentages must therefore be interpreted cautiously and cannot determine the best treatment for every patient.
