Gastrointestinal complications (GICs) are common after aortic surgery, leading to increased morbidity and mortality. Currently, no risk factors are identified, making prevention impossible.

Area of Science:

  • Vascular Surgery
  • Gastroenterology
  • Surgical Complications

Background:

  • Gastrointestinal complications (GICs) following aortic surgery are significant but understudied.
  • Understanding GICs is crucial for improving patient outcomes after aortic revascularization.

Purpose of the Study:

  • To identify risk factors, associated events, and outcomes of GICs after aortic surgery.
  • To investigate the prevalence and impact of GICs in patients undergoing transperitoneal aortic revascularization.

Main Methods:

  • Secondary analysis of a prospective study involving 120 patients undergoing transperitoneal aortic revascularization.
  • Evaluation of GICs occurring within 30 days of surgery.

Main Results:

  • 21% of patients developed GICs, including paralytic ileus, upper GI bleeding, and Clostridium difficile enterocolitis.
  • GICs were associated with more intraoperative complications, greater blood loss, prolonged ventilation, and longer ICU stays.
  • Patients with GICs had higher rates of pulmonary and renal complications, and increased mortality due to multisystem organ failure.

    • Conclusions:

    • Gastrointestinal complications are prevalent after aortic surgery and linked to severe morbidity and mortality.
    • Intraoperative events causing visceral hypoperfusion and mechanical causes contribute to GICs.
    • No predictive risk factors for GICs were identified, indicating current inability to prevent these complications.
