Background:
Previous studies have demonstrated a high incidence of acute pancreatitis (AP) in New Zealand, with Maori having the highest reported incidence worldwide. It is possible that barriers to healthcare exist for rural and Maori patients, leading to poorer outcomes. The aim of this study is to compare differences in severity and outcomes in patients with AP with regards to rurality and ethnicity.
Methods:
Multicentre retrospective study of all adults aged >16 years who were admitted to any hospital with AP in Northland between 1 January 2014 and 31 December 2018 was performed. Pancreatitis severity was classified using the Revised Atlanta classification. The primary outcome of interest was the difference in severity of pancreatitis with regards to rurality and ethnicity. Secondary outcomes of interest included clinical outcomes, aetiology of AP and re-presentation rates.
Results:
A total of 468 patients were included. There was no difference found between rural and urban or Maori and non-Maori patients with regards to disease severity, length of stay, mortality or intensive care unit admission rate. A significant difference in aetiology was found between Maori and non-Maori patients, with a higher rate of gallstone pancreatitis in Maori. There was no difference in local complications or number of re-presentations between groups.
Conclusion:
This study showed no difference in the severity or outcomes of AP across rural and urban patients in the Northland region of New Zealand. Secondary outcomes were broadly comparable between groups, with a higher rate of gallstone pancreatitis found in Maori compared to non-Maori.

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...

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
