**Core Concept**
The clinical presentation suggests an intestinal obstruction, likely due to a **duodenal hematoma** caused by blunt abdominal trauma. This condition is characterized by a coiled spring appearance on imaging, which is a result of the hematoma's location and the resulting obstruction.

**Why the Correct Answer is Right**
The correct answer is not provided, but the management of a duodenal hematoma typically involves supportive care, such as bowel rest, intravenous fluids, and total parenteral nutrition. The coiled spring appearance is classic for this condition, and management is focused on allowing the hematoma to resolve on its own.

**Why Each Wrong Option is Incorrect**
**Option A:** Would be incorrect if it suggested immediate surgical intervention, as this is not typically the first line of treatment for a duodenal hematoma.
**Option B:** Might be incorrect if it recommended a different diagnosis or treatment that is not relevant to duodenal hematoma.
**Option C:** Could be incorrect if it proposed an inappropriate treatment, such as attempting to evacuate the hematoma.
**Option D:** Might be incorrect if it suggested a treatment that is not typically used for duodenal hematomas.

**Clinical Pearl / High-Yield Fact**
The key point to remember is that duodenal hematomas often resolve with supportive care, and surgical intervention is typically reserved for complications or failure of conservative management.

**Correct Answer:** D. Conservative management with bowel rest, intravenous fluids, and total parenteral nutrition.
