Small intestine ischemia simulating primary colonic disease.

S N Glick, S K Teplick, M S Whiteman

    Summary

    Small intestine ischemia can mimic colonic diverticulitis on initial imaging. Early consideration of small intestine ischemia is crucial, especially with non-specific findings, to prevent complications like necrosis.

    Area of Science:

    • Gastroenterology
    • Abdominal Imaging
    • Surgical Pathology

    Background:

    • Colonic diverticulitis and small intestine ischemia share overlapping clinical presentations.
    • Diagnostic imaging can be challenging in differentiating these conditions.
    • Prompt diagnosis is essential to prevent severe complications.

    Purpose of the Study:

    • To highlight the diagnostic challenges in distinguishing small intestine ischemia from colonic diverticulitis.
    • To identify key radiographic findings that may suggest small intestine ischemia.
    • To emphasize the importance of further imaging when initial studies are non-specific.

    Main Methods:

    • Retrospective review of four patients with surgically confirmed small intestine ischemia.
    • Analysis of clinical, radiographic (plain abdominal radiography, barium enema), and surgical findings.
    • Correlation of imaging findings with intraoperative confirmation of serosal inflammation.

    Main Results:

    • Initial studies showed generalized small intestine distention and non-specific colonic abnormalities (extrinsic impression, thumbprinting, spiculation).
    • Serosal inflammation of the sigmoid colon due to adherent ischemic small intestine was confirmed surgically.
    • Delayed surgical intervention led to small intestine necrosis in two patients.

    Conclusions:

    • Small intestine ischemia can present with radiographic findings mimicking colonic diverticulitis.
    • Non-specific barium study findings in patients with suspected colonic issues warrant consideration of small intestine ischemia.
    • Further diagnostic imaging (e.g., angiography, small intestine follow-through) is recommended in equivocal cases.
