Learning points

Early pancreatitis
  • Ultrasound is indicated in the first 24 hours, mainly to identify gallstones as the cause of pancreatitis rather than to contribute to the diagnosis

  • Early endoscopic retrograde cholangiopancreatography (ERCP) should be considered in patients with gallstone induced acute pancreatitis if cholangitis and biliary obstruction are suspected

Deteriorating pancreatitis
  • To stage, and identify complications in, patients with persisting organ failure, signs of sepsis, or deterioration in clinical status 3-7 days after admission, a contrast enhanced computed tomography (CE-CT) scan should be considered

  • Early CE-CT (<72 hours after presentation) may underestimate the extent of necrosis as there is often a lag effect between disease extent and radiological appearances, therefore giving false assurance and less reliable surgical information on the extent of pancreatic necrosis

Obstructive pancreatitis
  • Despite the high spatial resolution of CE-CT, detection of gallstones within the common bile duct can be limited by their isodensity to the bile fluid; however, sensitivity to stones is very good and similar to that of magnetic resonance imaging

  • ERCP and endoscopic ultrasound are yet more sensitive but are invasive

Severe pancreatitis
  • CE-CT remains the preferred imaging modality for severe pancreatitis; its ready availability and use in subsequent interventional procedures, with excellent depiction of any complications, makes it the front runner

  • Magnetic resonance imaging has a growing evidence base, but it is not used widely yet

An active 73 year old patient with a history of cholecystectomy, hypothyroidism, and hypertension presented to the emergency department with a five hour history of severe epigastric pain. Her admission blood tests showed an amylase of 782 U/L and a white cell count of 21.2×103/µL, with a neutrophil count of 17.5×103/µL. The patient’s initial modified Glasgow score for predicting the severity of pancreatitis on admission was two, scoring on both age and white cell count. A repeat Glasgow score the following day …
