The patient in the above question is treated by observation for 8 weeks. He continues to be symptomatic with epigastric pain. A repeat abdominal CT scan reveals a persistent 6 cm pseudocyst in the region of the body of the pancreas. The pseudocyst is unilocular and demonstrates a well-defined rim of fibrous tissue. The gastric antrum is displaced anteriorly. Using CT guidance, 300 ml of fluid is aspirated from the lesion which is shown to be collapsed radiographically. No further intervention is performed. What is the risk of pseudocyst recurrence after simple aspiration?
A. 80–85%
B. 60–65%
C. 40–45%
D. 20–25%
