Area of Science:

  • Gastroenterology
  • Human Physiology
  • Microbiology

Background:

  • Limited knowledge exists regarding healthy human colonic function compared to dysfunction.
  • Accessing the colon for in vivo studies presents significant challenges.
  • Previous research often utilized cleansed or defunctioned colons, potentially skewing results.

Purpose of the Study:

  • To highlight the importance of understanding healthy colonic function.
  • To discuss the limitations of current methods for studying the colon.
  • To emphasize the colon's role as a metabolic organ influenced by microflora.

Main Methods:

  • Review of existing research on colonic access and function.
  • Analysis of studies involving patients with stomas.

  • Consideration of intestinal intubation and colonoscopy techniques.

    • Main Results:

    • The colon conserves water and electrolytes and facilitates fecal evacuation.
    • Emerging evidence shows the colon as a metabolic organ impacting systemic metabolism.
    • Colonic microflora significantly contributes to the colon's metabolic activities.

    Conclusions:

    • The functioning colon differs significantly from a defunctioned one.
    • Methodological limitations necessitate cautious interpretation of past in vivo colonic studies.
    • Further research is needed to fully elucidate the function of the healthy human colon.
