Comparison of the diagnostic Accuracy of 4 hours\' Serum Lipase and Amylase in Estimation of Pancreatitis in patients Planned (Endoscopic Retrograde Cholangio-Pancreatography) for Pancreatic and Biliary Ductal Disease.
Pak J Med Health Sci Jan ;14(2):572-5.

Aim: To compare the diagnostic accuracy of four-hour serum lipase and amylase in determination of pancreatitis among patients planned for endoscopic retrograde cholangio-pancreatography due to bile duct or pancreatic disease. Method: This Cross-sectional study was held at the Faculty of Gastroenterology; Sheikh Zaid Lahore Hospital among patients of both gender with age range from 20-80 years and various pancreatic and biliary ductal diseases intended for endoscopic retrograde cholangio-pancreatography. Results: The specificity, sensitivity, NPV, PPV and diagnostic accuracy of serum amylase were 89%, 85.8% and 87.6% and 89% correspondingly. Although serum lipase is 100% correct in the diagnosis of pancreatitis after endoscopic retrograde cholangio-pancreatography. One of the analysis suggested that serum amylase specificity, sensitivity, NPV and PPV were81.25%, 85%, 14.7% and 99.29%and serum lipase specificity, sensitivity, NPV and PPV were 87.5%, 84.5%, 15% and 99.52%. Conclusion: Therefore, serum lipase is more precise than serum amylase in diagnosing pancreatitis after endoscopic retrograde cholangio-pancreatography. We now have local evidence that will be important in the local environment.
