Morphology

sphincterotomy = sphincter (semi-transparent) = sphincter + otomy

Formally composed of 'sphincter' + the medical suffix '-otomy' meaning surgical cutting; the structure is literal but the suffix is specialized and unfamiliar to most learners.

Etymology

Sphincterotomy starts with sphincter, from a Greek word meaning 'to bind' or 'tighten', and ends with -otomy meaning 'cutting into', just like in tracheotomy. So a sphincterotomy is literally cutting a tight muscle that closes an opening, which is why the operation frees the muscle and helps it work better.
