Introduction: Pancreatitis is one of most complex and clinically challenging of all abdominal disorders. USG and abdominal CT are the most commonly used diagnostic imaging modalities for the evaluation of pancreas. Computed Tomography (CT) is highly accurate and sensitive than USG in both diagnosing as well as demonstrating the extent. Early assessment of the cause and severity of acute pancreatitis is of utmost importance for prompt treatment and close monitoring of patient with severe disease. CT is the imaging method of choice for assessing the extent of acute pancreatitis and for evaluating complications.

Aim: To assess prognostic correlation and clinical outcome of acute pancreatitis on the basis of CT severity index.

Materials and Methods: A prospective study of 50 cases was carried out in the Department of Radio Diagnosis, with complaint suggestive of acute pancreatitis on the basis of clinical/laboratory/ultrasonography findings were evaluated in Siemens somatom 40 slice ct . The severity of pancreatitis was scored using CT severity index, modified severity index and revised Atlanta classification and classified into mild, moderate, severe categories. Clinical follow-up of the patients was done in terms of the following parameters: Length of hospital stay, Need for surgery or percutaneous intervention, Evidence of infection in any organ system, Occurrence of organ failure- respiratory, cardiovascular, renal, hepatic and haematological system, death. The clinical outcome was compared with the currently accepted Balthazarís CTSI and Modified Morteleís CTSI and revised Atlanta classification in all the cases.

Results: Gall stone disease was most common aetiological factor seen in 40%, cases it was more common in females than males. Alcohol was second most common aetiological factor seen in 38% cases and was noted only in males. Pleural effusion was the most common extra-pancreatic complication seen in 46% cases. Balthazar grade C was the most common (40%) followed by grade D and E (25% each). Acute peri-pancreatic collection was the most common findings seen in 72% cases. Majority of the cases (42%) were categorized as mild pancreatitis according Balthazar CTSI score. Majority of the cases (44%) were categorized as severe pancreatitis according modified CTSI. Majority of the cases were categorized as mild pancreatitis according revised Atlanta classification. Organ system failure, death were more seen in severe grade in modified CTSI and revised Atlanta classification.

Conclusion: Modified CT severity index makes the score easier to calculate and reduces the inter-observer variation. Scores obtained with the modified Mortele index, show a stronger statistical correlation for all clinical outcome parameters in all the patients better than the Balthazar index.
