Introduction: Early assessment of acute pancreatitis severity is particularly important for its adequate treatment. Objective: To establish the usefulness of non-invasive intra-abdominal pressure (IAP) measurement for such assessment. Material and method: IAP was measured using the Kron technique (bladder pressure), in 78 patients with acute pancreatitis at 24, 48, and 72 hours after the onset of the disease, mean values were obtained, and they were compared for both mild and severe forms of the disease, according to APACHE II and Ranson scores; and the Tomographic Index was also used. A correlation between these parameters was also assessed. Results: In mild disease cases, mean values for the aforementioned parameters at 24, 48, and 72 hours were 5.85 ± 1.08; 7.57 ± 2.36, and 7.95 ± 1.21 mm Hg; and for the severe form, mean values were 10.39 ± 1.67; 11.91 ± 3.07...
