When the liver scars, blood can’t flow through it normally. Portal pressure climbs. Blood reroutes through smaller vessels, including the veins lining the lower oesophagus, which aren’t designed for that volume or pressure. More than half of all cirrhosis patients develop varices. First bleed mortality sits between 15 and 20%. The endoscope is the primary tool for stopping active bleeding, for preventing the first bleed, and for monitoring between sessions. No medication does what band ligation does. And the window for intervention is narrow.
According to Dr. Vipulroy Rathod, Gastroenterologist in Mumbai, “Variceal bleeding is one of the few genuine GI emergencies where minutes change outcomes. Band ligation within 12 hours of presentation is the standard; waiting for the patient to stabilise without scoping first is the wrong sequence.”
Known cirrhosis with vomiting blood or black stools?
What Endoscopic Techniques Treat Esophageal Varices?
The technique depends on where the varix sits, how actively it’s bleeding, and what the scope can access.
- Band ligation: Rubber bands at the varix base cut off blood supply and cause thrombosis. First-line for acute bleeding and elective obliteration.
- Sclerotherapy: Sclerosant injected into or beside the varix when banding isn’t technically possible or the view is too poor for bands.
- Glue injection: Cyanoacrylate for gastric varices polymerises on blood contact and occludes the vessel. EVL doesn’t work reliably in the stomach fundus.
- Drug-scope combination: Vasoactive drugs go in before the scope to narrow portal vessels and clear the field. An experienced endoscopist runs both arms together.
Liver cirrhosis stage directly determines how fast varices grow treating the liver disease and the varices as separate programmes is where management goes wrong.
How Do Prophylaxis Stages Work in Variceal Management?
Varices don’t always bleed on first presentation. What happens next depends entirely on what the screening scope finds.
- Screening scope: Every new cirrhosis diagnosis gets an upper GI scope varix grade, red wale signs, and location together set the management path.
- Primary prophylaxis: Large varices or red wale signs in someone who hasn’t bled yet get treated with EVL or beta-blockers. Watching confirmed high-risk varices isn’t a valid option.
- Acute bleeding: Vasoactive drugs before the scope, EVL within 12 hours, antibiotic cover throughout. Antibiotics cut rebleeding risk in cirrhotics by half.
- Secondary prophylaxis: First bleed means 60% rebleeding risk within a year without treatment. EVL every two to four weeks until obliteration is confirmed on scope not assumed from symptoms.
EUS shows perforating vessels and collateral anatomy the standard scope misses, useful specifically in recurrent or refractory cases where routine banding keeps failing.
When Does Endoscopic Treatment Stop Being Enough?
EVL handles most bleeds. Some it doesn’t. The escalation path is defined.
- TIPS: Two failed haemostasis attempts mean TIPS, a portosystemic shunt that drops portal pressure when the scope has reached its limit.
- Balloon tamponade: Sengstaken-Blakemore tube as a mechanical bridge. 24 hours maximum. Buys time for TIPS, not a standalone treatment.
- Post-obliteration follow-up: Varices come back as portal hypertension continues. Scope at three to six months post-obliteration, then annually indefinitely.
- Liver disease itself: Fatty liver progressing to NASH cirrhosis drives variceal recurrence. Repeated banding without treating the underlying disease is managing a symptom on a loop.
People with known liver disease noticing raised liver enzymes on routine blood tests alongside new upper abdominal fullness or easy bruising need a variceal screening scope portal hypertension builds silently before the first bleed announces it.
Key Takeaways
- First bleed mortality from varices is 15 to 20% that number moves with how fast the scope gets in
- EVL is first-line; sclerotherapy comes in when banding isn’t technically possible
- High-risk varices on screening scope mean treatment starts not a monitoring plan
- One bleed without secondary prophylaxis means 60% chance of another within a year
- Symptom improvement after EVL doesn’t mean obliteration only a follow-up scope confirms it
- Varices come back as cirrhosis worsens; the endoscopic programme doesn’t end at obliteration
Frequently Asked Questions
Endoscopic variceal ligation rubber band application for both acute bleeding and elective obliteration.
Three to five sessions typically, every two to four weeks, confirmed on scope rather than assumed.
Yes, portal hypertension doesn’t resolve with obliteration, so varices regrow and surveillance continues.
Two failed haemostasis attempts on scope; that’s when TIPS decompresses portal pressure instead.
