Summary

Computed tomography (CT) aids in diagnosing bowel infarction, a severe condition often presenting with abdominal pain. Key CT findings include bowel wall thickening, gas within the bowel wall or mesentery, and vascular occlusion.

Area of Science:

  • Radiology
  • Gastroenterology
  • Emergency Medicine

Background:

  • Bowel infarction is a life-threatening condition with challenging clinical and radiographic diagnosis.
  • Computed tomography (CT) is frequently employed for evaluating severe abdominal pain of unknown origin.

Purpose of the Study:

  • To define the characteristic computed tomography (CT) findings in patients diagnosed with bowel infarction.
  • To improve the diagnostic accuracy of CT for bowel infarction.

Main Methods:

  • Retrospective review of CT findings in 22 patients with confirmed mesenteric infarction.
  • Categorization of infarction causes into mesenteric arterial occlusion, mesenteric venous occlusion, and nonocclusive etiologies.

Main Results:

Related Experiment Videos

  • Common CT abnormalities included bowel wall thickening (19/22), intramural gas (11/22), and peritoneal gas or fluid (12/22).
  • Other significant findings were intramural low attenuation zones (8/22), mesenteric gas (5/22), and mesenteric vascular occlusion (8/22).
  • A variety of CT findings were observed across different causes of mesenteric infarction.

Conclusions:

  • CT demonstrates specific abnormalities that are crucial for diagnosing bowel infarction.
  • The diagnosis of bowel infarction should be strongly considered in patients presenting with severe abdominal pain of unknown etiology undergoing CT evaluation.
