Computed tomographic (CT) enteroclysis combines fluoroscopic and CT imaging for small-bowel examination. This advanced technique offers superior visualization for various conditions, complementing capsule endoscopy.

Area of Science:

  • Radiology
  • Gastroenterology
  • Medical Imaging

Background:

  • Computed tomographic (CT) enteroclysis is a hybrid imaging technique.
  • It integrates fluoroscopic intubation-infusion small-bowel examinations with abdominal CT.
  • Advancements in multidetector CT technology have led to its evolution.

Purpose of the Study:

  • To describe the technical modifications and applications of CT enteroclysis.
  • To evaluate its diagnostic performance compared to other small-bowel imaging modalities.
  • To define its role in investigating specific small-bowel pathologies.

Main Methods:

  • CT enteroclysis utilizes two main technical modifications: positive enteral contrast without IV contrast, and neutral enteral contrast with IV contrast.
  • The procedure involves intubation and infusion of contrast material followed by multi-detector CT scanning.

  • Comparison with other imaging techniques like barium enteroclysis and capsule endoscopy was performed.

    • Main Results:

    • CT enteroclysis demonstrates superiority over peroral small-bowel examinations, conventional CT, and barium enteroclysis.
    • It is highly effective for diagnosing small-bowel obstruction and unexplained gastrointestinal bleeding.
    • Its performance is comparable to other methods, with a noted limitation in detecting early apthous ulcers of Crohn disease.

    Conclusions:

    • CT enteroclysis is a versatile and effective imaging modality for small-bowel disease.
    • It serves as a valuable tool, particularly for Crohn disease, small-bowel obstruction, and obscure GI bleeding.
    • It is complementary to capsule endoscopy in elective small-bowel investigations.
