Area of Science:

  • Gastroenterology
  • Medical Imaging
  • Diagnostic Ultrasound

Background:

  • Colonic diverticulitis diagnosis can be challenging with clinical evaluation alone.
  • Accurate and timely diagnosis is crucial for effective management of acute and complicated diverticulitis.

Purpose of the Study:

  • To prospectively evaluate the clinical value of high-resolution real-time sonography for diagnosing acute and complicated colonic diverticulitis.
  • To compare ultrasound findings with clinical examination in patients presenting with abdominal complaints.

Main Methods:

  • Prospective study of 130 consecutive patients with suspected colonic diverticulitis.
  • High-resolution real-time sonography with graded compression was performed.
  • Ultrasound results were compared with clinical assessment and subsequent diagnoses.

Main Results:

  • Sonography achieved 97.7% overall accuracy, 98.1% sensitivity, and 97.5% specificity for diverticulitis.
  • Characteristic ultrasound findings included hypoechogenic wall thickening and target-like appearance.
  • 92% of abdominal abscesses were detected, with 7 cases managed by percutaneous drainage.

Conclusions:

  • High-resolution sonography with graded compression is highly sensitive and specific for diagnosing acute colonic diverticulitis.
  • Ultrasound is valuable for detecting complications such as abscesses, guiding treatment decisions.
  • Sonography significantly enhances diagnostic accuracy compared to initial clinical evaluation.
