Key Messages


  • Protracted diarrhea of infancy or short bowel syn-
    drome (SBS) requires parenteral nutrition together
    with oral feeding (OF) or enteral feeding (EF). The
    use of the gastrointestinal (GI) tract as early and as
    much as possible, according to clinical tolerance,
    should be promoted and feeding aversion pre-
    vented

  • Adaptation – the physical and physiological pro-
    cesses by which the intestine compensates for loss
    of intestinal length or function – is optimized with
    the provision of OF or EF

  • Direct mucosal contact with nutrients, pancreatico-
    biliary secretions and neurohormonal factors ex-
    plains how the use of the GI tract promotes physio-
    logical intestinal adaptation. It may also contribute
    to preventing cholestasis and liver disease

  • The intestinal microbiota has both positive (short-
    chain fatty acid production) and deleterious effects
    (intraluminal bacterial overgrowth)

    • The types of diet regarding breast milk, protein hy-
      drolysates and formulas containing amino acids or
      long- or medium-chain fatty acids remain contro-
      versial. The routes (oral, gastric and transpyloric)
      and the modes (bolus, continuous or both) of feed-
      ing are also debated. Very few randomized trials
      have been performed © 2015 S. Karger AG, Basel




Introduction

The so-called protracted diarrhea of infancy
(PDI), which has become a rare condition in de-
veloped countries, is caused by severe malabsorp-
tion secondary to an acquired intestinal mucosal
injury due to infection, inflammation or allergic
reaction. ‘Intractable diarrhea of infancy’ refers to
congenital enteropathies involving the develop-
ment or renewal of intestinal mucosa that lead to
very long-lasting or often irreversible intestinal
failure (IF) [1]. Short bowel syndrome (SBS) is the
leading cause of IF and is a state of malabsorption
following extensive small intestinal resection.
The functional consequences as well as the prog-
nosis of SBS depend on the age-adjusted small
bowel length, site of resection, presence or ab-
sence of the ileocecal valve (ICV) and occurrence
