Comparison of Modified Atlanta Classification With Modified CT Severity Index in Acute Gallstone Pancreatitis

Abstract

Acute Pancreatitis is one of the commonest gastro-intestinal diseases, in which patients need emergency hospitalization. It carries 10-30% mortality in severe cases. Early identification of severe cases helps in prognostication of the disease and institution of aggressive treatment. Aim To evaluate the severity of acute gall stone pancreatitis using Modified Atlanta Classification at admission and 48 hours. To compare severity of acute pancreatitis as assessed by Modified Atlanta Classification with Modified CT Severity Index (CTSI) in the second week. Materials and Methods We use Modified Marshal Score, as recommended by Revised Atlanta Classification, in our study group of 26 patients. Patients were classified into Mild, Moderate, and Severe categories at 48hrs. Contrast Enhance Computer Tomography of chest and abdomen (Gold standard) was performed at 2 weeks of presentation. Using Modified CTSI Score, patients were again categorised into Mild, Moderate, Severe cases. Results Modified Atlanta Classification correctly picked up the severe pancreatitis cases, as early as at 48hrs, with 100% sensitivity and specificity, which corresponded with CTSI at 2wks.
