Summary

Endoscopic abdominal wall components separation (EACS) is a new, minimally invasive technique that effectively increases abdominal capacity and reduces intraabdominal pressure in a porcine model of abdominal compartment syndrome (ACS). This procedure shows promise for early intervention.

Area of Science:

  • Surgical Innovation
  • Gastroenterology
  • Critical Care Medicine

Background:

  • Elevated intraabdominal pressure (IAP) above 14 mm Hg causes significant pathophysiological issues.
  • Current interventions for abdominal compartment syndrome (ACS) carry high morbidity and are not suitable for early disease stages.
  • Anatomical principles of abdominal wall component separation informed the development of a novel percutaneous procedure.

Purpose of the Study:

  • To develop and evaluate a minimally invasive percutaneous procedure for increasing abdominal capacity and decreasing intraabdominal pressure.
  • To assess the efficacy of endoscopic abdominal wall components separation (EACS) in a porcine model of ACS.

Main Methods:

  • A porcine model was utilized to assess changes in abdominal capacity via helium insufflation.

  • Intraabdominal hypertension was induced using corn oil to measure changes in IAP and intestinal mucosal oxygenation.
  • Endoscopic abdominal wall components separation (EACS) was performed to evaluate its impact.

    • Main Results:

    • EACS significantly increased abdominal capacity by approximately 1 L (P < 0.001).
    • During induced intraabdominal hypertension, EACS reduced intraabdominal pressure by 31.6% (P < 0.001).
    • Intestinal PO(2) increased by 61% following EACS (P = 0.012), indicating improved tissue oxygenation.

    Conclusions:

    • Endoscopic abdominal wall components separation (EACS) is a feasible and effective minimally invasive procedure.
    • The EACS technique demonstrated significant improvements in abdominal capacity, reduced intraabdominal pressure, and enhanced intestinal oxygenation in a porcine ACS model.
    • This approach holds potential for early intervention in abdominal compartment syndrome.
