Two days after a Whipple procedure, the patient has 30 cm of white opaque drainage from the drain. What is the next best step in evaluation?

• A. Stop drainage
• B. Send fluid for amylase level
• C. Start broad-spectrum antibiotics
• D. Order a CT abdomen scan

Answer: (B)

A drain producing white, opaque fluid after a pancreaticoduodenectomy raises suspicion for a pancreatic fistula from the pancreatojejunal anastomosis. The most direct way to evaluate this is to measure the amylase content of the drain fluid. A drain amylase level markedly higher than the serum amylase strongly suggests that pancreatic juice is leaking into the drain, confirming a postoperative pancreatic leak. This simple, noninvasive test helps guide management and can be done immediately before considering imaging or therapeutic interventions. If the amylase is not elevated, consider other causes of drainage and pursue further evaluation as indicated. Stopping the drain or starting antibiotics without evidence of a leak would not address the suspected problem.
