Colonoscopy
Colonoscopía
Also: Colonoscopia (regional variant)
What it means
A colonoscopy is a procedure in which a doctor uses a flexible tube with a camera on one end, called a colonoscope or scope, to look inside the rectum and colon. Before the exam you follow bowel prep instructions: the bowel prep clears the stool out of your colon so the doctor can see the colon during the procedure, and it involves taking laxatives and sometimes a clear liquid diet. The procedure is done at a hospital or outpatient center and usually takes 30 to 60 minutes. You get sedatives or anesthesia through an IV, and afterward you need someone to drive you home. During the exam the doctor may remove polyps or do a biopsy. In Spanish the term is colonoscopía, also written colonoscopia.

Colonoscopía, with a written accent on the i, is the heading of the MedlinePlus en español health topic page, while the text of the same page writes colonoscopia without the accent, the spelling NIDDK also uses. The word is feminine: la colonoscopia, una colonoscopia. The instrument is el colonoscopio, which NIDDK also calls endoscopio.
Words for the day before the exam: bowel prep is preparación intestinal, a clear liquid diet is dieta de líquidos claros, and laxatives are laxantes. For stool, NIDDK writes materia fecal and MedlinePlus en español writes heces. On the day itself, MedlinePlus en español speaks of sedantes o anestesia por vía intravenosa (IV sedatives or anesthesia), and NIDDK of una aguja intravenosa (IV). Polyps are pólipos and a biopsy is una biopsia. For the ride home, MedlinePlus en español says necesitará que alguien lo lleve a casa (you will need someone to take you home), and NIDDK calls the place where the exam is done un centro ambulatorio (an outpatient center).
