Elevated SGOT (AST) and SGPT (ALT) after a CECT abdomen with normal other liver function tests is likely due to contrast-induced transient hepatic injury, and I recommend monitoring your liver enzymes without specific intervention, as these values usually normalize within 24-72 hours. This is a common and typically benign reaction to the iodinated contrast media used during the scan. The evidence from various studies, including 1, suggests that elevated liver enzymes can be caused by various factors, but in the context of a CECT abdomen, contrast-induced transient hepatic injury is a likely cause.
Some key points to consider:
- Stay well-hydrated by drinking plenty of water (at least 2-3 liters daily) for the next few days to help your kidneys clear the contrast media.
- Avoid alcohol and hepatotoxic medications like acetaminophen (Tylenol) for 3-5 days to prevent additional liver stress.
- If you develop symptoms like severe abdominal pain, persistent nausea, vomiting, or yellowing of skin/eyes, seek immediate medical attention.
- The contrast media can cause temporary metabolic changes in liver cells that lead to enzyme leakage into the bloodstream without causing actual liver damage, which explains why other liver function parameters remain normal.
- A follow-up liver enzyme test in 1-2 weeks would be reasonable to confirm normalization, as suggested by the general approach to elevated liver enzymes in 1.
It's worth noting that while some studies, such as 2 and 3, discuss the role of elevated liver enzymes in predicting intra-abdominal injury, these studies are not directly relevant to the context of a CECT abdomen with normal other liver function tests. Similarly, study 4 discusses the interaction between medications and liver enzyme abnormalities, but this is not directly applicable to the current scenario. Study 5 suggests the value of abdominal ultrasound in evaluating asymptomatic patients with abnormal liver function tests, but this is not necessary in this case, given the likely cause of contrast-induced transient hepatic injury.
