Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease of unknown cause that is characterized pathologically by an inflammatory and fibrotic process centered on the epithelium, leading to diffuse biliary stenosis and increased wall thickness throughout the intra- and extra-hepatic biliary trees.


Diagnostic Criteria of Primary Sclerosing Cholangitis (PSC)

It is necessary to exclude IgG4-related sclerosing cholangitis, secondary sclerosing cholangitis caused by diseases with an obvious pathogenesis, and malignant diseases such as biliary cancer.

A. Diagnostic items

I. Major items

  A. Biliary tract imaging

      1) Cholangiographic findings characteristic of PSC

      2) Cholangiographic findings not specific to PSC

B. An increased alkaline phosphatase level

II. Minor items

  a. Association with inflammatory bowel disease

  b. Liver histology: Fibrous cholangitis/onion skin lesion

B. Diagnosis

Definite diagnosis

  • A1) +B  
  • A1) +a
  • A1) +b
  • A2) +B+a+b

Probable diagnosis

  • A1)
  • A2) +B+a
  • A2) +B+b
  • A2) +a+b

Possible diagnosis

  • A2) +a 
  • A2) +b


Lists of secondary sclerosing cholangitis

Congenital

  • Caroli’s disease 
  • Cystic fibrosis

Chronic obstruction

  • Choledocholithiasis
  • Biliary stricutures (secondary to surgical trauma, chronic pancreatitis) 
  • Anastomotic stricutures in liver graft
  • Neoplasmas (benign, malignant, metastatic)

Infectious

  • Bacterial cholangitis
  • Recurrent pyogenic cholangitis
  • Parastic infection (cryptosporidiosis, microsporidiosis)
  • Cytomegalovirus infection

Toxic

  • Accidental alcohol, formaldehyde, hypertonic saline instillation in the bile ducts

Immunologic

  • Eosinophilic cholangitis
  • Acquired immunodeficiency

Ischemic

  • Vascular trauma
  • Posttraumatic sclerosing cholangitis
  • Post-transplantation hepatic artery thrombosis
  • Hepatic allograft rejection (acute, chronic)
  • Intra-arterial, chemotherapy-related injury
  • Transcatheter arterial embolization therapy

Infiltrative disorders

  • Systemic vasculitis
  • Amyloidosis
  • Radiation injury
  • Sarcoidosis
  • Systemic mastocytosis
