Acute Pancreatitis (part 3) - Pseudocysts, Pain Control, and a few other pearls

Pancreatic pseudocysts present significant clinical challenges due to their unpredictable nature, often requiring a conservative "wait and see" approach as many resolve spontaneously. These collections of pancreatic secretions, which form at least four weeks after pancreatitis, must be distinguished from walled-off pancreatic necrosis because the latter necessitates different interventions like surgical necrosectomy. While CT scans are common initial diagnostic tools, MRCP provides superior anatomical detail for planning invasive procedures such as cystogastrostomy. Effective management also requires aggressive pain control, often via opioid PCA, to prevent pulmonary complications like atelectasis. Furthermore, clinical guidelines dictate that cholecystectomy should be performed before discharge in mild gallstone pancreatitis but deferred in necrotizing cases until inflammation subsides. Clinicians must remain vigilant for secondary hospital-acquired issues, including ARDS and sepsis, while monitoring for transient endocrine insufficiency that can manifest as diabetes following severe pancreatic injury.
