Medical Therapy

Medical therapy of Toxic megacolon include:

• 1.General considerations
  • 1.1.Complete bowel rest
  • 1.2.Intravenous fluid support to
  • 1.3.Electrocytes monitoring and correction of abnormalities
  • 1.4.Withdrawal of all anticholinergics, antidiarrheal and narcotics
  • 1.5.Rule out infectious etiology
• 2.Decompression
  • 2.1.Rectal tube
  • 2.2.Nasogastric or long nasointestinal tube

  Note: Long intestinal tubes are considered to be more effective than nasogastric tubes in colonic decompression but should be placed into the ileum under fluoroscopic guidance.

  • 2.3.Repositioning maneuvers

  Note: Maneuver 1: Asking patients to roll into the prone position for 10–15 minutes every 2–3 hours and encourage them to pass gas

  Note: Maneuver 2: Turning to the prone knee-elbow position, which moves the rectum to the highest point in the body
