ENDOSCOPY BAND
Endoscopic Band Ligation (EBL), or endoscopic variceal ligation (EVL), is a minimally invasive procedure using an endoscope to place tiny rubber bands around enlarged veins (varices) in the esophagus or stomach
Patients must fast for 6–8 hours
The doctor inserts an endoscope equipped with a banding device through the mouth.
4 to 6 bands are typically placed in one session.
Patients are monitored in recovery for about 2 hours
Endoscopic Band Ligation (EBL), or endoscopic variceal ligation (EVL), is a minimally invasive procedure using an endoscope to place tiny rubber bands around enlarged veins (varices) in the esophagus or stomach. This cuts off blood supply to the veins, causing them to shrink, scar, and fall off, which prevents or treats life-threatening bleeding commonly caused by liver cirrhosis.
Key Details of the Procedure
- Purpose: Primarily treats esophageal varices to stop acute bleeding or prevent future ruptures.
- Method: A device on the endoscope tip uses suction to draw the vein into a chamber, where a small elastic band is deployed.
- Procedure Details: It is usually done as an outpatient procedure under mild sedation, taking approximately 30–45 minutes.
- Recovery: Banded veins typically slough off (die and fall away) within a few days, and the area heals with minimal scarring.
- Devices: Multiband ligators (4-10 bands) are often preferred over single-band devices as they allow multiple, rapid applications without re-inserting the endoscope.
Risks and Considerations
- Side Effects: A sore throat or temporary swallowing irritation is common.
- Complications: Rarely, risks include return of bleeding, infection, esophageal perforation, or stricture (narrowing of the esophagus).
- Follow-up: Repeat sessions may be necessary to completely treat all varices.
