Faecal Calprotectin and 7-α Cholestenone Levels in Microscopic Colitis: Experience from Edinburgh.

Introduction: Microscopic colitis (MC) is an important cause of chronic, watery diarrhoea. Currently, there is no specific biomarker available to guide diagnosis. The use of faecal calprotectin (FCP) as a potential marker has been addressed in only a few studies.

Aortoenteric fistula: a rare but critical cause of small bowel bleeding discovered on capsule endoscopy.

A 78-year-old man attended for outpatient capsule endoscopy, to investigate a recent history of unexplained small bowel bleeding. His previous medical history included an abdominal aortic aneurysm repair 6 years ago. Soon after capsule ingestion, he experienced sudden onset abdominal pain and collapsed on hospital grounds.

Mapping the distribution of small bowel angioectasias.

Angioectasias are a prominent cause of small bowel (SB) bleeding frequently identified during capsule endoscopy (CE). Subsequent management depends upon grade/severity and location. There is increasing evidence that the location of SB angioectasias is not random.
