Context:
An uncomplicated and easy-to-use method of pre-estimating the severity of gallstone pancreatitis shortly after admission was required in order to direct clinicians for monitoring and/or transferring to a specialized center.
Objective:
To determine the role of brief assessment in pre-estimating the severity of gallstone pancreatitis at admission.
Patients:
Fifty-eight patients with gallstone pancreatitis were consecutively followed regarding the course of complications.
Main Outcome Variables:
Sensitivity analysis of the Biliary Ranson score (>3), the modified Imrie score (>3), the acute physiology and chronic health evaluation II (APACHE-II) score (>5), white blood cell count (>14.5 x10(3)/dL), blood urea nitrogen (>12 mg/dL), random blood sugar (>150 mg/dL), pulse rate (>100 beats/min) and combinations of the four brief assessments were compared using the z-test. Two-tailed P values less than 0.05 were considered statistically significant.
Results:
Both the Biliary Ranson score >3 and the modified Imrie score >3 had a sensitivity of 96.4% and a specificity of 96.7%. Both the APACHE-II score >5 and random blood sugar >150 mg/dL had a sensitivity of 89.3% which is comparable to a Biliary Ranson score >3 and a modified Imrie score >3.
Conclusion:
As compared to a Biliary Ranson score >3, a modified Imrie score >3 and an APACHE-II score >5, random blood sugar >150 mg/dL can be considered as an oversimplified and effective prognostic indicator at admission in patients with gallstone pancreatitis.

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...
