Abstract:
Acute cholangitis is a potentially severe infection of the biliary tract, resulting from a biliary obstruction. The most frequent cause of cholangitis is common duct stones. Biliary tract obstruction and secondary bacterial colonization lead to infection. In most cases, the causative agents are intestinal microflora, mostly aerobic microorganisms (and, to a lesser extent, anaerobic bacteria). The Charcot triad constitutes the most frequent symptomatology. Diagnosis is confirmed by means of radiological techniques, such as ultrasonography, computed tomography scan, or magnetic resonance imaging of the liver, in which signs of obstruction of the biliary tract can be detected and its etiology can often be determined. In most patients the treatment of choice is early appropriate antimicrobial therapy and biliary drainage, generally using endoscopic techniques.
Insights
Acute cholangitis, a severe biliary tract infection, often stems from common duct stones causing obstruction. Prompt antimicrobial therapy and biliary drainage are key treatments for this condition.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Medical Imaging
Background:
- Acute cholangitis is a serious biliary tract infection linked to obstruction.
- Common bile duct stones are the most frequent cause of this obstruction.
- Bacterial colonization, primarily from intestinal microflora, drives the infection.
Purpose of the Study:
- To summarize the etiology, diagnosis, and management of acute cholangitis.
- To highlight the role of biliary obstruction in disease development.
- To outline current treatment strategies for acute cholangitis.
Main Methods:
- Literature review of acute cholangitis.
- Analysis of diagnostic imaging techniques (ultrasonography, CT, MRI).
- Summary of recommended therapeutic interventions.
Main Results:
- Common duct stones are the primary cause of biliary obstruction leading to cholangitis.
- Charcot triad (fever, jaundice, abdominal pain) is the typical presentation.
- Radiological imaging confirms obstruction and aids etiological diagnosis.
Conclusions:
- Early antimicrobial therapy and biliary drainage are crucial for managing acute cholangitis.
- Endoscopic retrograde cholangiopancreatography (ERCP) is a common biliary drainage technique.
- Effective management relies on timely diagnosis and intervention to prevent severe outcomes.

Acute 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:
