General Surgery · Gastrointestinal surgery: diverticular haemorrhage
Sample itemA 72-year-old man passes a large volume of fresh red blood per rectum. After resuscitation his pulse and blood pressure are stable, but bleeding continues and an urgent colonoscopy cannot identify the source because of blood. Known diverticulosis is present. What is the best next investigation?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. CT angiography
In brisk lower gastrointestinal bleeding with a non-diagnostic colonoscopy, CT angiography is the preferred next test. It localises active bleeding and guides embolisation or surgery. Barium studies and capsule endoscopy are unsuitable in an actively bleeding patient.
Option by option
A. Barium enema
A barium enema is not used in acute bleeding and would obscure later endoscopy or angiography.
B. Plain abdominal radiograph
A plain film cannot show a bleeding point.
C. Capsule endoscopy
Capsule endoscopy is slow and unsuitable for ongoing brisk haemorrhage.
D. CT angiography (correct)
Correct. It is fast, widely available and shows the site of active extravasation.
