Objectives:
There is no marker that can accurately predict the development of pancreatic necrosis in edematous acute pancreatitis (AP). This study aimed to investigate the factors associated with necrosis development in cases of edematous AP and to create an easy-to-use scoring system.
Methods:
We retrospectively reviewed patients diagnosed with edematous AP between 2010 and 2021. Among the patients, those who were found to have developed necrosis during follow-up were categorized as the necrotizing group, whereas the others constituted the edematous group.
Results:
With multivariate analysis, white blood cell, hematocrit, lactate dehydrogenase, and C-reactive protein levels at the 48th hour were revealed to be independent risk factors for necrosis. Using these 4 independent predictors, the Necrosis Development Score 48 (NDS-48) was derived. While the cutoff value was 2.5, the sensitivity and specificity of the NDS-48 for necrosis were 92.5% and 85.9%, respectively. The area under the curve value of the NDS-48 for necrosis was 0.949 (95% confidence interval, 0.920-0.977).
Conclusions:
White blood cell, hematocrit, lactate dehydrogenase, and C-reactive protein levels at the 48th hour are independent predictors of necrosis development. The NDS-48, a new scoring system created with these 4 predictors, satisfactorily predicted the development of necrosis.

01:27Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

01:24Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
