【Abstract】 Objective To evaluate the value of urinary trypsinogen-2 test for screening acute pancreatitis in patients with acute abdomen. Methods Urinary trypsinogen-2 as well as serumal and urinary amylase were assayed in 346 patients with acute abdomen. Results The diagnosis of acute pancreatitis was established in 41 patients. Among them,38 cases with positive urinary trypsinogen-2 were found, the sensitivity was 92.7%. 15 cases with false positive were found in 305 cases of non-pancreatitis patients,the specificity was 95.1%. All of the five patients with severe acute pancreatitis were positives. Conclusion Urinary trypsinogen-2 test is an easy and rapid diagnostic method with high sensitivity and specificity for screening acute pancreatitis in patients with acute abdomen.更多还原
