Abstract
- BACKGROUND/AIMS
The 2012 revision of the Atlanta classification of acute pancreatitis (AP) by international consensus has been published and in use. This study investigated and compared clinical outcome of patients with AP stratified according to the 1992 Atlanta classification and revised classification.
METHODS
A total of 574 AP patients from six referral hospitals between January 2012 and July 2013 were included. Medical records were reviewed retrospectively. Severity assessment according to both classifications was done. Demographics, organ failure, local complications, length of stay, and clinical outcome were recorded.
RESULTS
There were 377 males (65.7%). Median age was 55.4 years. Two most common causes of AP were alcohol (n=238, 41.5%) and gallstone (n=193, 33.6%). According to revised classification, there were mild (n=356, 62%), moderately severe (n=197, 34.3%), and severe AP (n=21, 3.7%). Length of stay showed gradual increment with increase in degrees of severity according to the revised classification (5.9 days in mild AP, 8.3 days in moderately severe AP, and 13 days in severe AP, p<0.001). All the patients with mild and moderately severe AP improved, but all the 11 cases without improvement belonged to severe AP.
CONCLUSIONS
The revised classification seems to be a good predictor for clinical outcome of AP.
