The liver and pancreas in acute necrotising pancreatitis
Abstract:
Pancreatic fibrosis was found in 23 of 31 cases of acute necrotising and haemorrhagic pancreatitis; however, in the cases with a history of six days or less neither the extent nor the frequency of fibrosis differed significantly from those in controls. There was no histological evidence that duct or vascular lesions are necessary for the disease to occur. The liver was examined in 26 cases and showed cholestasis in 12, including 10 of 20 cases without a biliary aetiology and only two of six cases with biliary tract disease. In no case did the liver show specific features of alcoholic damage.
Insights
Pancreatic fibrosis occurs in most acute necrotising pancreatitis cases. Early stages (≤6 days) showed no significant difference in fibrosis compared to controls, suggesting delayed development.
Area of Science:
- Gastroenterology
- Pathology
Background:
- Acute necrotising pancreatitis is a severe condition.
- Pancreatic fibrosis is a potential complication.
Purpose of the Study:
- To investigate the occurrence and timing of pancreatic fibrosis in acute necrotising pancreatitis.
- To examine the role of duct/vascular lesions and liver changes in this condition.
Main Methods:
- Histological examination of pancreatic tissue from 31 patients.
- Analysis of disease duration (≤6 days vs. >6 days).
- Liver examination in 26 cases.
Main Results:
- Pancreatic fibrosis was present in 23 of 31 cases.
- No significant difference in fibrosis extent or frequency was observed in cases with symptom duration of six days or less compared to controls.
- No histological evidence suggested duct or vascular lesions are necessary for disease onset.
- Cholestasis was observed in 12 of 26 examined livers, more frequently in cases without biliary aetiology.
- No specific features of alcoholic liver damage were noted.
Conclusions:
- Pancreatic fibrosis is common in acute necrotising pancreatitis but may not be an early feature.
- Duct or vascular lesions are not essential for the development of the disease.
- Liver cholestasis is a notable finding, particularly in non-biliary cases.
