Objective: To evaluate the effects of iodine contrast media and gadoteric acid in acute necrotizing pancreatitis.

Methods: Fifty rabbits were distributed in 5 groups: 10 rabbits were assigned in the control group (group 5) and 40 rabbits were assigned in the pancreatitis group, wherein acute necrotizing pancreatitis was induced through retrograde injection of 5% sodium taurocholate (1 mL/kg weight) in the main pancreatic duct. After 3 hours, they were randomized to receive endovenous iodinized nonionic contrast medium (group 1), iodinized ionic contrast medium (group 2), gadoteric acid (group 3), and physiological serum at 0.9% (group 4). Six hours after induction of pancreatitis, these animals were reoperated. During surgery, pancreatic tissue flow through laser Doppler, hematometric values, biochemistry, and histopathology analysis by hematoxylin and eosin were done. Statistical analysis using Kruskal-Wallis, Fisher-Freeman-Halton, and parametric t tests was performed.

Results: There was statistical significance when comparing tissue flow before and after induction of pancreatitis (P < 0.0001). Ionic and nonionic contrast media and gadoteric acid did not increase the grade of pancreatic necrosis (P > 0.05).

Conclusions: Ionic and nonionic contrast media and gadoteric acid did not produce adverse effects in the present model of acute necrotizing pancreatitis.
