A contrast agent swallow algorithm accurately differentiates patients with small-bowel obstruction, guiding timely surgical or conservative treatment. This diagnostic tool improves patient care and reduces healthcare burdens.

Area of Science:

  • Gastroenterology
  • Surgical Diagnostics
  • Emergency Medicine

Background:

  • Small-bowel obstruction is a common emergency medicine condition with significant patient and healthcare system impact.
  • Contrast agent swallow has emerged as a valuable tool for managing small-bowel obstructions.

Purpose of the Study:

  • To investigate the role of contrast agent swallow in a diagnostic and treatment algorithm for small-bowel obstruction.
  • To evaluate the accuracy of this algorithm in identifying patients requiring surgery versus conservative management.

Main Methods:

  • A prospective controlled study of 181 patients with small-bowel obstruction.
  • Patients were stratified into immediate surgery (group 1) or Gastrografin® challenge (group 2) based on clinical signs.
  • The Gastrografin® challenge assessed contrast agent progression to determine treatment pathways.

Main Results:

  • The Gastrografin® challenge was used in 58% of patients, with 19.1% requiring surgery after the challenge.
  • Failure of the Gastrografin® challenge accurately predicted the need for surgery (80% intraoperative strangulation detection).
  • The challenge demonstrated high accuracy (96%) and sensitivity (100%) in predicting the need for surgical exploration.

Conclusions:

  • A simple algorithm centered on contrast agent swallow effectively differentiates patients with small-bowel obstruction.
  • This approach facilitates accurate and timely decisions for conservative or operative treatment.
  • The algorithm improves diagnostic accuracy and optimizes patient management pathways.
