Prognostic value of multidetector computed tomography in bowel infarction

Area of Science:

• Radiology
• Gastroenterology
• Vascular Surgery

Background:

• Bowel infarction, a critical condition resulting from vascular obstruction, necessitates accurate diagnosis and prognostic assessment.
• Computed tomography (CT) plays a crucial role in evaluating abdominal emergencies.

Purpose of the Study:

• To correlate computed tomography (CT) findings with patient outcomes in cases of bowel infarction.
• To establish the prognostic value of multidetector CT (MDCT) findings and their relationship to the type of vascular obstruction.

Main Methods:

• Twenty-seven patients with bowel infarction due to vascular obstruction underwent multidetector CT (MDCT) evaluation.
• The chi-square test was employed to analyze the correlation between CT findings and outcomes (p ≤ 0.05).

Main Results:

• MDCT accurately identified the nature of ischemia in all patients, with arterial occlusion in 67% and venous obstruction in 33%.
• Overall mortality was 63%, significantly higher in arterial (89%) versus venous (11%) occlusions.
• Findings like bowel-wall hyperdensity, loss of wall enhancement, and wall thickening predicted good outcomes, while bowel-loop dilatation, intramural pneumatosis, and various forms of gas (mesenteric, portal, pneumoperitoneum) indicated poor outcomes.

Conclusions:

• Multidetector CT (MDCT) is highly effective in determining the type of bowel ischemia.
• MDCT provides critical prognostic information, aiding in the management of patients with bowel infarction.
