After a Whipple procedure, which diagnostic test should the nurse prepare to confirm an anastomotic leak?

• A. Abdominal X-ray
• B. Upper GI study with Gastrografin
• C. CT abdomen with contrast
• D. Ultrasound of the liver

Answer: (B)

When a patient has had a Whipple procedure, the major concern is an anastomotic leak at the connections between the pancreas, bile duct, and stomach/duodenum. The most reliable way to confirm a leak is by imaging the upper GI tract with a water-soluble contrast agent. An upper GI study using Gastrografin will illuminate the stomach and the surgical connections and will show any leakage of contrast from the anastomosis into the peritoneal cavity. This direct visualization makes it the best choice for confirming a leak, because it demonstrates whether the pathway is intact or compromised. Using a water-soluble contrast is preferred in this situation because if there is a breach and the contrast leaks out, it is less irritating to the peritoneum than barium. Abdominal X-ray alone isn’t specific enough to identify a leak, and a CT with contrast, while helpful for detecting collections or inflammatory changes, isn’t the primary method to definitively demonstrate a leak at the anastomosis. An ultrasound of the liver doesn’t assess the anastomotic sites and won’t confirm a leak. Nursing steps would include preparing the patient for the contrast study, ensuring appropriate NPO status, coordinating with radiology, and monitoring for potential contrast reactions while observing for signs of peritonitis or respiratory irritation if Gastrografin is aspirated.
