Serosal patching on intestinal defects after surgery hinders adaptation and absorption, negatively impacting weight and intestinal length. This surgical technique appears detrimental to recovery and nutrient absorption in patients with short bowel syndrome.

Area of Science:

  • Gastroenterology
  • Surgical Research
  • Regenerative Medicine

Background:

  • Short bowel syndrome (SBS) treatment aims to increase intestinal absorptive surface.
  • Mucosal regeneration on serosal patched intestinal defects is a potential therapeutic strategy.
  • Previous long-term studies indicated serosal patching is detrimental to intestinal adaptation.

Purpose of the Study:

  • To evaluate the early effects of serosal patching on intestinal adaptation and function after enterectomy.
  • To investigate the role of polyamine metabolic pathways in this process.

Main Methods:

  • New Zealand white rabbits underwent either 50% distal enterectomy alone (GP II) or enterectomy with serosal patching of ileal defects (GP III).
  • Control group (GP I) was unoperated.

  • Morphological and functional changes, including body weight, remnant length, mucosal protein, villus height, in vitro mucosal function, crypt cell production rate, and polyamine pathway activity, were assessed.

    • Main Results:

    • Serosal patching (GP III) resulted in significant body weight loss compared to enterectomy alone (GP II).
    • Intestinal remnant length and mucosal protein content were significantly reduced in GP III.
    • Crypt cell production rate decreased, while ornithine decarboxylase and diamine oxidase activity increased in GP III, without altering polyamine levels.

    Conclusions:

    • Serosal patching impairs intestinal adaptation and absorption following massive enterectomy.
    • The impairment is partly due to decreased proliferative activity, not directly linked to altered polyamine levels.
    • This technique may be deleterious for patients with short bowel syndrome.
