**Core Concept**
Pancreatic pseudocysts are fluid collections that develop in the setting of pancreatitis or pancreatic trauma, characterized by a thick wall of fibrous tissue and no true epithelial lining. Management of complicated pseudocysts involves addressing the underlying cause, relieving symptoms, and preventing further complications.

**Why the Correct Answer is Right**
The management of complicated pancreatic pseudocysts often requires intervention to alleviate symptoms such as abdominal pain, jaundice, or gastrointestinal obstruction. This can be achieved through endoscopic drainage, percutaneous drainage, or surgical intervention, depending on the patient's condition and the pseudocyst's characteristics. Endoscopic ultrasound-guided drainage is a minimally invasive option that involves placing a stent or catheter to drain the pseudocyst.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify a management approach for complicated pancreatic pseudocysts. Simple pseudocysts without complications are often managed conservatively with observation.
**Option B:** This option is incorrect because antibiotics are not a primary treatment for pancreatic pseudocysts, although they may be used to manage secondary infections.
**Option C:** This option is incorrect because surgical intervention is not always necessary for complicated pancreatic pseudocysts, and may be associated with higher morbidity and mortality.

**Clinical Pearl / High-Yield Fact**
When managing complicated pancreatic pseudocysts, it is essential to identify the underlying cause of the pseudocyst, such as pancreatitis or trauma, to guide treatment and prevent further complications.

**Correct Answer:** C. Surgical intervention.
