Value of modified APACHE II score in predicting postoperative complications in patients with acute obstructing colorectal carcinoma / 中华胃肠外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the value of modified acute physiologic and chronic health score (APACHE II score) in predicting postoperative complications in patients with acute obstructing colorectal carcinoma.</p><p><b>METHODS</b>Postoperative complications in 92 patients with acute obstructing colorectal carcinoma were evaluated by APACHE II score and modified APACHE II score (severe organ dysfunction and immune damage in chronic health indicators were replaced by the duration and degree of obstruction, which were considered as the severity of intestinal obstruction). The sensitivity, specificity, and Youden index were compared with regard to complication prediction. Receiver operating characteristic curves were plotted to calculate area under the curve(AUC).</p><p><b>RESULTS</b>Twenty-five patients developed postoperative complications including 3 deaths. The APACHE-II score(13.72±4.24), modified APACHE II score (19.28±4.92), intestinal obstruction severity score (5.56±2.20) were significantly higher in patients with complications than those in patients without complications (10.58±3.44, 14.69±3.73, 4.10±1.52, all P<0.01). The sensitivity, specificity, accuracy, Youden index, and AUC were 0.640, 0.940, 0.859, 0.580, and 0.839 for the modified APACHE-II score with 20 being the optimal cut-off point, respectively, and were 0.560, 0.896, 0.804, 0.456, and 0.784 for APACHE-II (14 was the optimal cut-off point), respectively.</p><p><b>CONCLUSION</b>The modified APACHE-II score system with the intestinal obstruction severity score is a better prediction method for the occurrence of postoperative complications in patients with acute obstructing colorectal carcinoma.</p>
