    Summary

    Ultrasonography effectively identifies colonic diverticulitis by detecting thickened, hypoechoic bowel walls. This imaging technique is recommended before contrast enemas for suspected diverticulitis diagnosis.

    Area of Science:

    • Gastroenterology
    • Diagnostic Imaging
    • Abdominal Surgery

    Background:

    • Diverticulitis is a common condition affecting the colon.
    • Accurate diagnosis is crucial for appropriate management.
    • Conventional imaging methods like barium enemas have limitations.

    Purpose of the Study:

    • To describe sonographic findings in patients with colonic diverticulitis.
    • To evaluate the utility of ultrasonography in diagnosing diverticulitis.
    • To compare ultrasonography with contrast enema examinations.

    Main Methods:

    • Sonographic examination of 16 patients with suspected diverticulitis.
    • Detailed analysis of colonic wall thickness, echogenicity, and segment length.
    • Correlation of sonographic findings with clinical presentation and other imaging modalities.

    Main Results:

    • Inflamed colonic segments showed hypoechoic and thickened walls (5-17 mm).
    • Sonography visualized long inflamed segments (6-9 cm) and adjacent less involved areas (7-15 cm).
    • Abscesses were detected in 7 of 16 patients; barium extravasation was seen in only 2.

    Conclusions:

    • Ultrasonography is a valuable tool for diagnosing colonic diverticulitis.
    • It can identify key features like wall thickening and hypoechogenicity.
    • Recommended prior to contrast enemas, especially when abscesses are suspected.
