Description
Summary:Objective: to upgrade the quality of predicting an outcome in patients with acute colonic ileus (ACI) in relation to the level of a constant potential. Material and methods. Four hundred and seventy-one case histories of patients operated on for ACI caused by colonic cancer were retrospectively analyzed. Results. An analysis of the capacity of scales to accurately predict a fatal outcome in the general population showed that the CR-POSSUM scale significantly underrated the risk for a fatal outcome (O/R ratio = 1.684 (1.515—1.871); however, the APACHE III and SAPS II scales demonstrated an adequate accuracy (O/R ratio = 1.112 (1.088—1.136) and 1.069 (1.054—1.085), respectively). When dividing subgroups according to the value of constant potential, the greatest agreement was achieved predominantly in Subgroup 1, by using the CR-POSSUM and APACHE III scales (the area under the characteristic curve was 0.913 and 0.93, respectively). It should be pointed out that all the scales had a good calibration after additional identification of subgroups, unlike in the general population of patients (p>0.05). The SAPS II scale also demonstrated a good calibration, but a low discriminating power particularly in groups with average and low negative values of a constant potential. Key words: severity rating scales, acute colonic ileus, constant potential.
