Acute cholangitis: a histopathologic study
Abstract:
We studied the histology of the liver in acute cholangitis to determine whether microscopic changes corresponded to the patients' clinical status. Thirty-four cases of acute cholangitis were divided clinically into mild and severe cases. The incidence of endotoxemia, gram-negative bacteremia, disseminated intravascular coagulation (DIC), and hepatic failure were significantly higher in the severe cases than in the mild ones. In the severe cases, the incidence of neutrophile infiltration into the sinusoids (12 of 16) and microabscesses in the lobules (11 of 16) was also significantly higher than in the mild cases. Finally, the incidence of portal thrombosis (10 of 16) and massive necrosis of the hepatic cells (5 of 16) was significantly higher in the severe than in the mild cases, especially in the patients who later died. The results suggest that neutrophilic infiltration into the sinusoid and microabscesses in the lobules is a characteristic finding in severe cholangitis.
Insights
Histological examination of the liver in acute cholangitis reveals that neutrophilic infiltration and microabscesses are characteristic of severe cases. These microscopic findings correlate with clinical severity and patient outcomes.
Area of Science:
- Hepatology
- Pathology
- Infectious Diseases
Background:
- Acute cholangitis is a serious liver infection.
- Understanding histological changes is crucial for assessing disease severity.
Purpose of the Study:
- To correlate liver histology in acute cholangitis with clinical status.
- To identify specific microscopic findings indicative of severe disease.
Main Methods:
- Histological examination of liver tissue from 34 acute cholangitis patients.
- Clinical classification into mild and severe cases.
- Analysis of microscopic findings against clinical severity.
Main Results:
- Severe cholangitis cases showed higher rates of endotoxemia, bacteremia, disseminated intravascular coagulation (DIC), and hepatic failure.
- Neutrophile infiltration into sinusoids and lobular microabscesses were significantly more frequent in severe cases.
- Portal thrombosis and massive hepatic cell necrosis were also higher in severe cases, particularly in non-survivors.
Conclusions:
- Neutrophilic infiltration and microabscesses are characteristic histological findings in severe acute cholangitis.
- These microscopic changes correlate with clinical severity and patient prognosis.
- Histopathology aids in differentiating disease severity and predicting outcomes in acute cholangitis.
