Paralytic Ileus

This is a ‘disordered neuromuscular transmission’ within the myenteric plexus Normally, the different parts of the bowel take different amounts of time to start working properly again (e.g., peristalsis and digestion):

  • Stomach: up to 24 hours
  • Small bowel <24 hours
  • Large bowel 24-48 hours
  • Longer than this can indicate ileus
  • Usually treated conservatively
  • Towards causes, optimize patient condition

Distinguishing mechanical small bowel obstruction and paralytic ileus may be difficult:

  • Both show distended bowel on x-ray
  • Both can present with constipation
  • Bowel sounds are absent in ileus
