The Predictive Value of Urinary Trypsinogen-2 Dipstick for Early Diagnosis of Acute Pancreatitis in Intensive Care

Abstract

Abstract Background Acute pancreatitis is a sudden inflammation in the pancreas, with potential and variable involvement of adjacent organs or other organ systems. Aim of the Work to evaluate the rule of urinary trypsinogen-2 using dipstick test in the diagnosis of acute pancreatitis. Patients and Methods This cross-sectional study was carried out in surgical intensive care unit, Ain Shams University hospitals, during a period of 6 months. Forty five patients were included in our study, thirty patients were diagnosed as acute pancreatitis and fifteen patients weren’t diagnosed as acute pancreatitis through cross sectional study. All patients were subjected to full history taking, full clinical examination, laboratory investigations including serum levels of renal function tests, CBC, total and direct bilirubin, liver enzymes, alkaline phosphatase, INR, amylase and lipase. Urinary trypsinogen-2 dipstick test was done. Also, radiological examinations were done using ultrasonography of abdomen and pelvis, computed tomography of the abdomen. Results The most common cause of acute pancreatitis was gall stone obstructive pancreatitis (70%) and we found that serum amylase and lipase were elevated in (83.3% and 86.7% respectively) in acute pancreatitis patients. While the sensitivity of urinary trypsinogen-2 dipstick test was 93.3% in acute pancreatitis patients. The specificity of serum amylase, serum lipase was 73.3% for both of them, while the specificity of urinary trypsinogen-2 was 100% in diagnosis of acute pancreatitis. Conclusion In-conclusion urinary trypsinogen-2 dipstick test is a promising low cost, bed side and easy test to be done in the diagnosis of acute pancreatitis.
