Result Interpretation

The more positive indicators among these 11 items, the more certain the severity of the disease and the worse the prognosis.

1-2 items indicate mild disease, while having more than 6 items indicates severe disease, with a mortality rate exceeding 50%. If 8 items are met, the mortality rate reaches 100%.

Explanation

There are various scoring systems for acute pancreatitis, with APACHE-II and Ranson being the most commonly used. The former is more complex but accurate, while the latter is more practical in clinical settings.
