EP-289 Acute gallstone pancreatitis – if a picture is worth a thousand words, how many images do we need?

Abstract Aims Accurate diagnosis and prompt definitive management of choledocholithiasis is vital in acute gallstone pancreatitis (GSP). Sensitivity detection varies across imaging modalities. Magnetic resonance cholangiopancreatography (MRCP) most sensitive, but may not be necessary, result delayed implementation management. We aimed to evaluate the range radiological investigations patients with GSP underwent at our Trust, clinical appropriateness MRCP if performed. Methods An observational study diagnosed between 01/05/2019 26/02/2021 was Data were collected from electronic patient records. Results 50 (median age 56years). 41 had transabdominal ultrasound (USS), 22 computed tomography (CT) 16 MRCP. Median waiting time 1, 0 4 days for respectively. All who prior USS and/or CT (Table 1). As management, 14% endoscopic retrograde (ERCP), 28% laparoscopic cholecystectomy 30% initial ERCP followed by cholecystectomy. readmitted Conclusions Detailed description CBD radiology reports mitigate need unnecessary subsequent imaging, reducing cost facilitating early recommend establishment a guideline streamline assessment pancreatitis.
