Dilatation

Dilatation (pronounced: /daɪˈleɪʃən/) is a term used in medicine to describe the enlargement, stretching, or expansion of a body part or structure. The term is derived from the Latin word "dilatare", which means "to enlarge" or "expand".

It can also refer to procedures that intentionally expand a structure, such as Balloon dilatation in angioplasty or Esophageal dilatation in the treatment of certain esophageal conditions.
