We used modern diagnostic methods of instrumental investigations. All patients in this work was divided to groups depended on estimating patient statement with APACHE II and RANSON scale. Instead at this, we estimated multislice computed tomography sings depended on Balthazar scale. This scale helped us to purpose existing and spreading of the lesion in pancreas, prognoses course of the disease after diagnosing disease. We entered new diagnostic and treatment algorithms, which helps to chose right surgical methods of treatment of acute pancreatitis in different stages of disease. After using this tactics in patients with difficult forms of acute pancreatitis (total ball 3-9 on integral scale RANSON and 9-20 on APACHE II scale) results was: mortality 25.9%, which conforms to low limit prognosing mor-tality in this group.
