Summary

Portal hypertensive gastropathy (PHG) involves gastric lesions in patients with portal hypertension. Severe PHG significantly increases bleeding risk, but propranolol and shunts can prevent it.

Area of Science:

  • Gastroenterology
  • Hepatology
  • Vascular Medicine

Background:

  • Portal hypertensive gastropathy (PHG) presents as diffuse gastric mucosal lesions in patients with portal hypertension.
  • Histology shows dilated submucosal and mucosal vessels without inflammation or erosions.
  • Endoscopic classification includes mild (mosaic pattern, reddening) and severe (cherry red spots) forms.

Purpose of the Study:

  • To define portal hypertensive gastropathy (PHG) and its clinical implications.
  • To elucidate the pathogenesis and risk factors associated with PHG.
  • To review management strategies for PHG-related bleeding.

Main Methods:

  • Review of histological and endoscopic findings in PHG.
  • Analysis of prevalence data for mild and severe PHG in cirrhotic patients.
  • Evaluation of risk factors, clinical manifestations, and treatment outcomes.

Main Results:

  • Mild PHG affects 65-90% of cirrhotic patients; severe PHG affects 10-25%.
  • Pathogenesis involves venous congestion and increased gastric blood flow; variceal sclerosis may contribute.
  • Severe PHG carries a high risk of overt (60%) and chronic (90%) bleeding over 5 years.

Conclusions:

  • Propranolol is the sole proven pharmacological treatment for preventing PHG bleeding.
  • Porto-systemic shunts and liver transplantation are effective interventions for PHG management.
