Q

bowel obstruction pathophysiology?

A
  • gas+faeces build up proximally -> vomiting, bowel dilatation
  • fluid not absorbed in colon - 3rd space loss - hypovolaemia
  • ischaemia, necrosis, perf
  • closed-loop obstruction - eg 2 points of adhesions, hernias, volvulus, LBO + competent ileocaecal valve
  • strangulated - blood supply compromised - pt more ill

Q

bowel obstruction Px? SBO vs LBO?

A
  • vomiting - green, bilious
