Objective:
To study the outcome of acute pancreatitis and risk factors for recurrent and chronic pancreatitis in a population based cohort of patients with first-time acute pancreatitis.
Methods:
All patients with first-time acute pancreatitis from 2006-2015 in Iceland were retrospectively evaluated. Medical records were scrutinized and relevant data extracted.
Results:
1102 cases of first-time acute pancreatitis were identified: mean age 56yr, 46% female, 41% biliary, 21% alcohol, 26% idiopathic, 13% other causes, mean follow-up 4yr. 21% had ≥1 recurrent acute pancreatitis which was independently related to alcoholic (vs. biliary hazard ratio (HR) 2.29, 95% confidence interval (CI) 1.51-3.46), male gender (HR 1.48, 95%CI 1.08-2.04), and smoking (HR 1.62, 95%CI 1.15-2.28). 3.7% developed chronic pancreatitis. Independent predictors were recurrent acute pancreatitis (HR 8.79, 95%CI 3.94-19.62), alcoholic (vs. biliary HR 9.16, 95%CI 2.71-30.9), local complications (HR 4.77, 95%CI 1.93-11.79), and organ-failure (HR 2.86, 95%CI 1.10-7.42).
Conclusions:
Recurrent acute pancreatitis occurred in one-fifth of patients. Development of chronic pancreatitis was infrequent. Both recurrent acute pancreatitis and chronic pancreatitis were related to alcoholic acute pancreatitis, while recurrent acute pancreatitis was associated with smoking and male gender, and chronic pancreatitis to recurrent acute pancreatitis, organ-failure, and local complications.

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...

01:26Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
01:26Pancreatic Juice and Secretion
When acidic chyme from the stomach enters the duodenum, it triggers the release of secretin, a hormone that prompts pancreatic juice secretion. After a fatty meal, cholecystokinin, another hormone, stimulates gallbladder contraction and enhances enzyme-rich...
