Emergency sclerotherapy effectively manages acute variceal bleeding, with over 90% of patients controlled. Repeat treatments ensure long-term control for esophageal varices, but failures may require alternative interventions.

Area of Science:

  • Gastroenterology
  • Hepatology
  • Endoscopic interventions

Background:

  • Esophageal variceal bleeding is a serious complication of portal hypertension.
  • Sclerotherapy is a primary treatment modality for variceal bleeding.

Purpose of the Study:

  • To outline effective sclerotherapy techniques for acute variceal bleeding.
  • To define management strategies for both acute and long-term control of esophageal varices.
  • To identify treatment options for sclerotherapy failures.

Main Methods:

  • Flexible endoscopy for diagnosis and immediate intervention.
  • Intravariceal or combined intravariceal/paravariceal sclerotherapy using ethanolamine oleate.
  • Balloon-tube tamponade for temporary control when immediate sclerotherapy is not feasible.

  • Repeat injection sclerotherapy at weekly intervals for eradication.
  • Surgical interventions (transection, portosystemic shunt) for refractory cases.

    • Main Results:

    • Emergency sclerotherapy controls over 90% of actively bleeding patients.
    • Repeat sclerotherapy is effective for long-term management and eradication of esophageal varices.
    • Surgical options are reserved for patients with recurrent bleeding or difficult-to-eradicate varices.

    Conclusions:

    • Sclerotherapy is a highly effective treatment for acute variceal bleeding and long-term management.
    • Individual units should employ techniques with which they have the most experience.
    • Liver transplantation should be considered for eligible patients, and prophylactic sclerotherapy is not currently indicated for non-bleeding varices.
