EVL banding

Endoscopic Variceal Ligation (EVL) banding is a medical procedure used to treat esophageal varices, which are enlarged veins in the esophagus (the tube connecting the throat to the stomach). Esophageal varices can occur in people with liver disease, particularly cirrhosis, where the liver is damaged and blood flow becomes restricted.

Why and when is it done

The purpose of EVL banding is to prevent or treat bleeding from the esophageal varices. The rubber bands placed around the varices cause them to shrink and eventually fall off, reducing the risk of rupture and bleeding. The procedure is generally performed as a preventive measure for high-risk patients with large varices or those who have previously experienced bleeding from varices.

Benefits of EVL banding

  • Prevention and control of bleeding
  • Minimally invasive procedure for shorter hospital stay and quick recovery
  • Safe procedure with low risk of complications
  • Effective long term results

Risks associated with EVL banding

While EVL banding is a very safe procedure, it does carry certain risks which come with every procedure. Rare complications of EVL banding may include:

  • Immediate bleeding during the procedure
  • Esophageal injury or perforation during the procedure
  • Risk of infection
  • Adverse reaction to sedation and anesthesia

How is the procedure performed

During an Endoscopic Variceal Ligation (EVL) banding procedure, the following steps are typically involved

  • Fasting is mandatory for clear view during surgery and low risk of infection. You may also receive sedation or anesthesia to help you relax and minimize any discomfort.
  • An anesthetic spray will be used to keep your mouth open along with mouth guard
  • The endoscope is inserted into your mouth to Identify the varices
  • Once the varices are identified, small rubber bands will be placed around them using a special instrument attached to the endoscope. The bands are then deployed, encircling the varix and causing it to constrict.
  • Repeated band placement: If you have multiple varices, the process will continue.
  • Once the desired varices have been banded, the endoscope will be slowly withdrawn. The procedure typically lasts around 30 minutes to an hour, depending on the complexity of the case.
