'intra-abdominal' originates from Latin, specifically the prefix 'intra-' meaning 'within' and 'abdomen' referring to the belly or stomach area.

'intra-abdominal' was formed by combining the Latin prefix 'intra-' with the English word 'abdominal', which itself comes from the Latin 'abdomen'.

Initially, it meant 'within the abdomen', and this meaning has largely remained the same in modern usage.
