Studies systematically documenting US findings in children with acute pancreatitis are limited. Pancreas duct dilation is described as the most reliable finding of acute pancreatitis but this has not been rigorously examined in children. To systematically document US findings in children with acute pancreatitis and to define interobserver agreement on those findings. In this cross-sectional study we retrospectively reviewed images for all pediatric patients <18 years of age who had been prospectively enrolled in a registry of patients with index admissions for acute pancreatitis between March 2013 and July 2020. Two blinded observers (R1, R2) reviewed the first transabdominal US examination performed within 2 weeks of the pancreatitis attack for each patient. In 141 children, US was performed at a median of 1 day (interquartile range [IQR]: 0, 1) following acute attack. Thirty-three (23%, R1) and 38 (27%, R2) children had no abnormal findings on US. Peripancreatic edema was the most frequent finding documented by both reviewers (63% R1, 54% R2). The pancreatic duct was visible in only 35% of the children and was dilated in only 12% (R1) and 14% (R2). There was substantial to almost-perfect agreement between reviewers on findings of acute pancreatitis (κ=0.62-1), including duct visibility. Peripancreatic edema was the most frequently identified finding in children with acute pancreatitis, present in up to 63%, with almost perfect interobserver agreement. Duct dilation, cited in the literature as a reliable finding of acute pancreatitis, was rarely identified in our sample.

UI MeSH Term Description Entries
D010179 Pancreas A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
D010195 Pancreatitis INFLAMMATION of the PANCREAS. Pancreatitis is classified as acute unless there are computed tomographic or endoscopic retrograde cholangiopancreatographic findings of CHRONIC PANCREATITIS (International Symposium on Acute Pancreatitis, Atlanta, 1992). The two most common forms of acute pancreatitis are ALCOHOLIC PANCREATITIS and gallstone pancreatitis.

D003430 Cross-Sectional Studies Studies in which the presence or absence of disease or other health-related variables are determined in each member of the study population or in a representative sample at one particular time. This contrasts with LONGITUDINAL STUDIES which are followed over a period of time.

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D015588 Observer Variation The failure by the observer to measure or identify a phenomenon accurately, which results in an error. Sources for this may be due to the observer's missing an abnormality, or to faulty technique resulting in incorrect test measurement, or to misinterpretation of the data. Two varieties are inter-observer variation (the amount observers vary from one another when reporting on the same material) and intra-observer variation (the amount one observer varies between observations when reporting more than once on the same material).
