Background Resources for January Case

Our current case focuses on whether C. difficile infection is possible in a patient with ileostomy. If you're not familiar with the procedure and terminology, it can be difficult to envision why the disconnect between the small intestine and colon matters in this particular case. The following freely available resources should help with visualizing the gastrointestinal anatomy and understanding the patient's situation.

Main Concepts
Anatomy of the Gastrointestinal Tract
  • MedlinePlus Medical Encyclopedia: Lower Digestive Anatomy (illustration)
  • National Digestive Diseases Information Clearinghouse: Your Digestive System and How it Works
  • MeSH Database: Gastrointestinal Tract

    Ileostomy - surgical procedure involving part of the small intestine
  • National Digestive Diseases Information Clearinghouse: Ileostomy, Colostomy, and Ileoanal Reservoir Surgery
  • UW Medical Center Ostomy Care Service: Colostomy or Ileostomy (click on Colostomy/Ileostomy to download and view a slideshow with illustrations)
  • United Ostomy Association: Ileostomy Guide (PDF)
  • MeSH Database: Ileostomy

    Clostridium difficile - a bacteria that lives in the large intestine
  • CDC: General Information About Clostridium difficile Infections
  • CDC: Clostridium difficile Information for Healthcare Providers
  • eMedicine: Clostridium difficile Colitis (the expected type of C. difficile infection; it was unusual in our patient, as the patient did not have a colon)
  • MeSH Database: Clostridium difficile

    Diarrhea
  • National Digestive Diseases Information Clearinghouse: Diarrhea
  • MayoClinic: Antibiotic-Associated Diarrhea
  • MeSH Database: Diarrhea

    Additional Topics

  • CDC: Ventilator-Associated Pneumonia
  • MeSH Database: The 2007 update of MeSH from NLM includes the new term, Pneumonia, Ventilator-Associated, which is new to MeSH this year.

    Ischemic Colon - when blood flow to your large intestine is diminished or blocked, leading to low oxygen in the affected area
  • MayoClinic: Intestinal Ischemia
  • MayoClinic: Ischemic Colitis
  • American College of Gastroenterology: Intestinal Ischemia
