Post-Pancreaticoduodenectomy Leak With Sepsis and Compartment Syndrome
A 62-year-old woman is on postoperative day 4 after a pylorus-preserving pancreaticoduodenectomy for ampullary adenocarcinoma. She is tachycardic at 124/min, blood pressure 90/56 mmHg on norepinephrine 0.12 µg/kg/min, urine output 15 mL/h, and lactate 3.8 mmol/L. Hemoglobin is 8.9 g/dL, WBC 18,000/µL, and drain amylase is 4,200 U/L. CT shows a 6-cm peripancreatic fluid collection and no free air. She has a soft abdomen with mild tenderness. She is on broad-spectrum antibiotics and has received 5 L of crystalloid in 24 hours. The interventional radiology service is available; the surgical team is considering reoperation.
1. How do you interpret the findings, and what are your first three management priorities?
Read the worked answer
The picture is a clinically relevant postoperative pancreatic fistula with associated sepsis and hypoperfusion, not simple fluid overload. The high drain amylase confirms a pancreatic leak; tachycardia, norepinephrine requirement, oliguria, and lactate indicate sepsis, with possible hemorrhagic shock from the hemoglobin drop. First priorities are source control, resuscitation, and broad-spectrum antibiotics with antifungal coverage if indicated. Send drain fluid for culture, obtain blood cultures, and check a CT angiogram if bleeding is suspected. Avoid dumping more crystalloid; use balanced resuscitation and vasopressors. The collection needs drainage, and the patient needs close ICU monitoring.
2. Would you recommend percutaneous drainage or reoperation now? Explain the reasoning.

Percutaneous drainage is reasonable first if the collection is well defined, the patient has no diffuse peritonitis or free air, and the pancreas is not frankly necrotic. The soft abdomen and localized 6-cm collection favor a drain. However, if she remains unstable, has evidence of ischemia, hemorrhage, or infected necrosis, reoperation is needed. A hybrid approach-IR drain now with a low threshold for surgery-is often best. The drain should be large-bore, and fluid should be sent for culture. If percutaneous drainage fails or the patient deteriorates, operate. Do not delay source control for repeated imaging.
3. Twelve hours later she has worsening oxygenation, bladder pressure 24 mmHg, and lactate 5 mmol/L. What now?
Read the worked answer
Worsening oxygenation, bladder pressure 24 mmHg, and rising lactate suggest abdominal compartment syndrome plus evolving ARDS. Intubate for respiratory failure, decompress the abdomen if the temporary closure or collection is contributing, and consider laparotomy for source control and decompression. Drain any new collection. Use lung-protective ventilation. The lactate rise should prompt a search for ongoing leak, ischemia, or bleeding. This is a failure of nonoperative management, and delaying surgery worsens outcomes.
