Summary
Secondary sclerosing cholangitis (SSC) is a severe biliary disease causing bile duct destruction. In critically ill patients, ischemic injury may drive rapid progression to cirrhosis and poor outcomes.
Area of Science:
- Hepatology
- Gastroenterology
- Biliary Medicine
Background:
- Secondary sclerosing cholangitis (SSC) is a chronic cholestatic liver disease.
- It involves bile duct inflammation, fibrosis, and destruction, leading to cirrhosis.
- SSC often follows bile duct injury from obstruction, surgery, or ischemia.
Purpose of the Study:
- To describe a newly recognized form of SSC in critically ill patients.
- To investigate potential mechanisms, particularly ischemic injury, in this patient group.
- To highlight the poor prognosis associated with SSC in critically ill individuals.
Main Methods:
- Review of clinical data and literature on SSC.
- Analysis of potential etiological factors in critically ill patients.
- Comparison of outcomes for SSC versus primary sclerosing cholangitis.
Main Results:
- Sclerosing cholangitis in critically ill patients is a distinct, aggressive form of SSC.
- Ischemic injury to the intrahepatic biliary tree is a suspected early event.
- SSC generally has limited therapeutic options and reduced survival, especially in critically ill patients.
Conclusions:
- SSC in critically ill patients progresses rapidly to liver cirrhosis.
- Ischemic cholangiopathy may be a key factor in this severe SSC subtype.
- Outcomes for SSC patients, particularly the critically ill, are significantly worse than for primary sclerosing cholangitis.

01:20Cholecystitis
Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
01:17Chronic Bowel Disorders: Introduction
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

01:21Chronic Pancreatitis II: Pathophysiology
Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...
01:23Cirrhosis I: Introduction
Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
01:24Cirrhosis II: Pathophysiology
Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
