Acute Pancreatitis (part 2) - Severe Pancreatitis, Pancreatic Necrosis, Antibiotic & Surgical Considerations

Severe acute pancreatitis requires a nuanced clinical approach, particularly regarding fluid collections and necrosis. While ultrasound serves as the initial diagnostic tool for identifying gallstones, contrast-enhanced CT scans should be reserved for assessing severity to avoid unnecessary radiation and contrast-induced kidney injury. Prophylactic antibiotics are not recommended for sterile necrosis, as evidence shows no clinical benefit and an excessively high number needed to treat. Instead, focus on aggressive early fluid resuscitation—ideally with lactated Ringer’s solution—during the first 12 to 24 hours to prevent ischemia. Surgical intervention, such as necrosectomy, should be delayed for at least four weeks to allow for the development of walled-off necrosis, which significantly improves outcomes. Management of intra-abdominal hypertension relies on medical strategies like diuretics or percutaneous drainage before considering surgical decompression as a last resort.
