What is a common post-operative complication identifiable on ultrasound?

A common post-operative complication identifiable on ultrasound is the formation of a hematoma or seroma. After surgical procedures, it is not uncommon for fluid to accumulate at the site of the incision or within a cavity where tissue has been manipulated.

A hematoma occurs when blood collects outside of blood vessels, usually due to bleeding that has not yet been reabsorbed by the body, while a seroma is a collection of clear serous fluid that can develop in the site of a surgical incision or trauma. Ultrasound is particularly effective in detecting these conditions due to its ability to visualize fluid collections and differentiate between solid and fluid-filled spaces. The appearance of a hematoma or seroma on ultrasound will typically show an anechoic or hypoechoic area, which facilitates a straightforward diagnosis that can inform post-operative management and care.

Other conditions, while notable, are less common as immediate post-operative complications. Enlarged lymph nodes might indicate an underlying infection or malignancy rather than a direct result of surgery. Fatty infiltration of the liver is usually a chronic condition related to metabolic factors and does not typically develop acutely post-surgery. Obstruction of bowel, while serious, is also less commonly seen immediately after surgery compared to fluid collections. Therefore,
