What is the significance of a computed tomography (CT) scan of the abdomen showing no definite acute abnormality, atherosclerotic calcifications of a mildly ectatic aorta, areas of atheromatous plaque formation, mild prominence of the intrahepatic and extrahepatic biliary ducts likely secondary to a history of cholecystectomy, and a moderate volume of stool within the colon?

From the Guidelines

The CT scan of the abdomen shows no acute abnormalities that require immediate intervention, and management should focus on addressing chronic findings and preventing future complications. There are several chronic findings including atherosclerotic calcifications in a mildly ectatic aorta with plaque formation, which indicates long-standing vascular disease but doesn't require urgent treatment 1. The bile ducts appear mildly dilated, but this is likely a normal finding given your history of gallbladder removal (cholecystectomy), as this anatomical change commonly occurs after this surgery.

• Key points to consider:
  • Atherosclerotic calcifications and plaque formation are indicative of vascular disease, and while they do not require immediate intervention, they should be discussed with your primary care provider to assess cardiovascular risk factors 1.
  • The mild dilation of the bile ducts is likely a consequence of the cholecystectomy, and as such, does not necessitate urgent attention unless accompanied by other symptoms such as jaundice or abdominal pain 1.
  • The moderate amount of stool in the colon suggests possible constipation, which can be managed through lifestyle modifications including increased fluid intake, a high-fiber diet, and regular physical activity.
• Recommendations for management:
  • Increase fluid intake to at least 8 glasses of water daily.
  • Add more fiber to your diet, aiming for 25-30g daily.
  • Engage in regular physical activity to help manage constipation and reduce cardiovascular risk.
  • If constipation persists, consider an over-the-counter stool softener like docusate sodium (100mg twice daily) or a gentle laxative like MiraLAX (17g in 8oz water daily).
  • Schedule a follow-up appointment with your primary care provider to discuss the atherosclerotic findings and assess cardiovascular risk factors, as guided by the most recent and highest quality study available 1.

From the Research

CT Abdominal Impressions

• No definite acute abnormality identified
• Atherosclerotic calcifications of a mildly ectatic aorta, with areas of atheromatous plaque formation noted 2
• Mild prominence of the intrahepatic and extrahepatic biliary ducts likely secondary to history of cholecystectomy, which may be associated with an increased risk of gallstone disease 3
• Moderate volume of stool within colon

History of Cholecystectomy

• May be associated with an increased risk of gallstone disease, although long-term use of statins has been shown to decrease this risk 3
• Can lead to postoperative biliary stricture and vascular injury, which may require liver resection in severe cases 4, 5
• Patients with a history of cholecystectomy may benefit from statin therapy to reduce the risk of cardiovascular disease, particularly if they have additional risk factors 6

Atherosclerotic Calcifications and Plaque Formation

• Associated with an increased risk of cardiovascular events, and may be reduced with statin therapy 2, 6
• Can lead to vascular injury and hepatic ischemia in patients with a history of cholecystectomy 5
• May be a sign of underlying dyslipidemia, which can be improved with statin therapy 6
