Colonic pseudoobstruction

Case contributed by Dr Chris O'Donnell

Presentation

Gross painless abdominal distension in an elderly patient

Patient Data

Age: 85
Gender: Male
CT

Gross colonic dilatation from caecum to anus with no obstructing lesion identified - typical of this syndrome.

Case Discussion

CT is helpful in delineating the cause of bowel dilatation.  Always look for a point of transition from dilated to collapsed bowel = site of obstruction.  In this case there is no transition point to the anus this mechanical obstruction is unlikely.  On that basis this is likely to be a functional disorder of the bowel ie poor or absent peristalsis.  Dilatation can be extreme even leading to venous ischaemia of the bowel wall and perforation.
