ABSTRACT

Background: Acute pancreatitis is the inflammation of pancreas. The computed tomography and modified computed tomography severity indexes have been designed to determine the severity of the pancreatitis.1 But there is a need to explore the more helpful tool for detection of severity of the pancreatitis.

Aim: To compare CTSI and MCTSI in terms of outcome of patients presenting with acute pancreatitis

Methods: This descriptive case series was done in Radiology department, Services Hospital Lahore from Mar 2015 to Aug 2015. Sample size consisting of 93 patients wereselected using consecutive non probability sampling method with clinical diagnosis of acute pancreatitis. These patients underwent contrast enhanced MDCT and the severity of the pancreatitis was scored using both the modified CT severity indexes and CT severity indexes. For both the CT and modified CT severity indexes, correlation between severity of pancreatitis and outcome of patients was estimated by using the percentage, frequency charts and pearsonchi-square test.

Results: In clinical outcome parameters i.e. the length of hospital stay (mean=20 sd 8.07), the occurrence of end organ failure (67/93), systemic infection (59/93) and the need for the surgical intervention were highly correlated with severe MCTSI than severe CTSI.

Conclusion:MCTSI is better and improved tool for screening of patients for severity of the acute pancreatitis. It can also help in the prediction of clinical outcome.
