Abstract OBJECTIVES: Acute pancreatitis may be the first presentation of pancreatic carcinoma (PaCa). The present study was designed to identify clinical findings suggestive of PaCa in patients with nonalcoholic nongallstone-related (NANG) acute pancreatitis and evaluate accuracy of endoscopic ultrasound for diagnosing PaCa in this setting. METHODS: This is a retrospective analysis of 332 consecutive patients who underwent endoscopic ultrasound-fine-needle aspiration after acute pancreatitis. Patients with gallstones or common bile duct stones, who were heavy or binge alcohol drinkers, or who had post-endoscopic retrograde cholangiopancreatography pancreatitis were excluded. RESULTS: Among 218 patients with NANG acute pancreatitis, 38 patients had PaCa. Age more than 50 years (P = 0.008), history of smoking (P < 0.001), weight loss of 10 lb or greater (P = 0.003), serum bilirubin levels of higher than 2 mg/dL (P = 0.035) or serum alkaline phosphatase level of higher than 165 U/mL (in patients with normal serum bilirubin levels) (P = 0.003), and radiological findings of an identifiable pancreatic mass (P = 0.001) or distal pancreatic atrophy (P = 0.006) had significant association with an underlying PaCa on multivariate analysis. Of the 38 patients with PaCa in this cohort, 37 had 2 or more of these findings. Endoscopic ultrasound-fine-needle aspiration had 99.5\% accuracy (98.6, 100\%) for diagnosing carcinoma in this clinical setting. CONCLUSIONS: The clinical criteria defined previously potentially can help select patients with NANG acute pancreatitis with a higher likelihood of an underlying pancreatic neoplasm for further imaging.
