What does appendicectomy mean?
An appendicectomy is a surgical operation in which the vermiform appendix is removed from the body. It is performed most often as an emergency procedure to treat acute appendicitis, a potentially serious inflammation of the appendix that can lead to rupture and peritonitis if left untreated. The operation may be carried out as open surgery through a small incision in the lower right abdomen or, increasingly, laparoscopically using keyhole instruments, which typically allows faster recovery and a shorter hospital stay. Appendicectomy is one of the most frequently performed emergency abdominal operations worldwide, and the term carries a firmly clinical, formal register — it belongs to surgical notes and medical literature rather than everyday conversation. The word is the standard British form of the operation's name, while American practice favours 'appendectomy'; both refer to exactly the same procedure. Knowing the term is useful for anyone reading medical reports, health journalism, or accounts of hospital care.
nounA surgical operation to remove the appendix, most commonly performed as an emergency treatment for acute appendicitis.
- The surgical removal of the appendix (vermiform appendix), typically to treat appendicitis.
"The surgeon performed an emergency appendicectomy after the patient's abdominal pain was diagnosed as acute appendicitis."
"She was rushed into theatre for an appendicectomy within hours of arriving at the emergency department."
"Laparoscopic appendicectomy has largely replaced the open procedure for uncomplicated cases, allowing most patients home within a day."
The plural is uncommon and appears mainly in statistical or collective contexts, such as describing a series of operations rather than multiple procedures on one patient.
"The hospital recorded over four hundred appendicectomies last year."
It's one of the most common emergency operations in the world — yet the two halves of the English-speaking world can't even agree on what to call it: 'appendicectomy' in Britain, 'appendectomy' in America.

Etymology of appendicectomy
The word combines 'appendic-', referring to the appendix (from Latin 'appendix', meaning 'something appended or attached'), with '-ectomy', a suffix of Greek origin (from 'ektomē', 'excision') used in surgery to denote the cutting out of an organ or tissue. The related condition it treats, appendicitis, entered medical terminology in the late nineteenth century following recognition of the appendix as a source of inflammation. Its American counterpart 'appendectomy' shares the same roots but drops the connecting 'i'. Cognates built on the same Greek excision suffix include gastrectomy, lobectomy, and vasectomy.
How appendicectomy is actually used
The term is chiefly British; American medical writing uses 'appendectomy'. In clinical contexts it appears almost exclusively in formal or technical registers. The plural is rare since the word usually refers to a single patient's operation.
Easily confused with appendicectomy
Both terms denote the same operation — removal of the appendix — but 'appendectomy' is the standard American spelling and pronunciation, while 'appendicectomy' is the traditional British form.
