Background Extrapancreatic necrosis is diagnosed on computed tomography (CT) as extrapancreatic changes that are more than fat stranding; both fluid collections and necrosis would have a similar appearance. The aim of this study was to determine the prognostic significance of differentiating peripancreatic necrosis from fluid collection on endoscopic ultrasound (EUS) in patients with presumed isolated extrapancreatic necrosis.Methods We carried out a retrospective analysis of prospectively collected data from 36 patients (25 males; age range 19-65 years) with acute pancreatitis (AP) and isolated extrapancreatic necrosis. On EUS, peripancreatic anechoic areas were labeled as peripancreatic fluid collections and peripancreatic heterogeneously echotextured areas as peripancreatic necrosis.Results The etiology of AP was alcohol in 16 (44.4%) patients, gallstone disease in 13 (36.1%), and other in 7 (19.4%). On EUS, 25 (69.4%) patients had peripancreatic necrosis and 11 (30.6%) patients had peripancreatic fluid collections. Compared with patients who had peripancreatic fluid collections, patients with peripancreatic necrosis had a signifi cantly higher frequency of pleural effusion (88% vs. 55%; P=0.04), organ failure (OF) (68% vs. 27%; P=0.03), and persistent OF (48% vs. 9%; P=0.03). The patients with peripancreatic necrosis also had a higher frequency of ascites (20% vs. 9%), need for intervention (20% vs. nil), surgery (8% vs. nil) and mortality (8% vs. nil), but these differences were not statistically significant.Conclusion Isolated extrapancreatic necrosis on contrast-enhanced CT comprises a heterogeneous group, with patients who show peripancreatic fl uid collections on EUS having a less severe disease course compared to patients with peripancreatic necrosis.Keywords Pancreatitis, pancreatic necrosis, endosonography, gallstones, organ failureAnn Gastroenterol 2017; 30 (2): 232-236 (EN)
