Summary

Endoscopic screening before major surgeries is often warranted, especially for organ transplants where the threshold for gastrointestinal disease is very low. This cost-benefit analysis supports pre-operative endoscopy to ensure patient safety and successful outcomes.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Health Economics

Background:

  • Gastroenterologists often perform endoscopic procedures to rule out serious gastrointestinal (GI) diseases before major surgeries.
  • The necessity and cost-effectiveness of these pre-operative endoscopic evaluations require assessment.

Purpose of the Study:

  • To evaluate the cost-benefit of pre-operative endoscopic screening for patients undergoing major surgical operations.
  • To determine the threshold probability for gastrointestinal disease that justifies endoscopic screening.

Main Methods:

  • A cost-benefit analysis was conducted using decision tree and threshold analysis.
  • The study included patients scheduled for organ transplants (liver, kidney) and other major surgeries.
  • Key outcome measures included the costs of medical and surgical procedures and the calculated threshold probability for GI diagnosis.

Main Results:

  • For organ transplants, the threshold probability for GI disease diagnosis via endoscopy is below 1%, suggesting routine screening is warranted.
  • For interventions like percutaneous transluminal coronary angioplasty and coronary bypass grafting, thresholds range from 3.2% to 6.5%.
  • This indicates endoscopic screening may be justified for lesser procedures if a comorbid condition could impact surgical success.

Conclusions:

  • Pre-operative endoscopic screening is justified before major surgical or other invasive medical interventions.
  • The analysis highlights the value of endoscopy in identifying potential GI complications that could affect surgical outcomes.
  • Further research could incorporate the costs of endoscopic complications into the model.
