Insisional

Insisional is an adjective that may be used to describe something related to an incision or the act of incising. It is not a standard term in contemporary medical or scientific English, and its use is very rare. The more common and widely accepted form is incisional.

Etymology and relation to related terms: The word is likely derived from the Latin incisio, meaning a cutting or incision, combined with the English adjectival suffix -al. Because incisional is the established form, insisional is generally considered a spelling variant or error in modern texts.

Usage and cautions: In current medical writing, the preferred term is incisional, as in incisional biopsy or incisional approach. If insisional appears, it is often a typographical error or an archaic usage; readers should prefer incisional in formal writing to avoid confusion. There is no recognized separate meaning for insisional that would distinguish it from its incisional counterpart in professional practice.
