Management of Esophageal Varices with Red Color Signs
Esophageal varices with red color signs require prophylactic treatment regardless of variceal size, using either non-selective beta-blockers (propranolol or nadolol) or endoscopic variceal ligation (EVL) to prevent first variceal bleeding. 1, 2
Understanding Red Color Signs
Red color signs are critical endoscopic findings that dramatically increase bleeding risk:
- Red wale marks are defined as longitudinal dilated venules resembling whip marks on the variceal surface 1
- Red spots (also called cherry red spots or hematocystic spots) are localized reddish mucosal areas on the varix surface 1
- These signs reflect structural changes in the variceal wall with decreased wall thickness, increased tension, and development of microtelangiectasias in areas of structural weakness 2
- 80% of patients with cherry red spots or blue varices with red color signs will experience variceal bleeding, making this a high-risk feature 2
Risk Stratification and Treatment Algorithm
Small Varices (<5mm) with Red Color Signs
For small varices with red color signs OR decompensated cirrhosis (Child B/C):
- Non-selective beta-blockers (propranolol or nadolol) should be initiated to prevent first variceal bleeding 1
- Adjust beta-blockers every 2-3 days until resting heart rate reaches 55-60 beats per minute 1
- Red color signs mandate prophylactic treatment even when varices are small 2
Large Varices (>5mm) with or without Red Color Signs
For large varices, choose one of the following:
- Non-selective beta-blockers (propranolol or nadolol) 1
- Carvedilol 1
- Endoscopic variceal ligation (EVL) 1
- Combination of NSBBs and EVL can also be considered for enhanced protection 1
Type of Red Color Sign Matters
Recent evidence shows important distinctions between types of red color signs:
- Hematocystic spots (HCS) are associated with significantly higher bleeding risk and earlier bleeding compared to red wale markings alone 3
- Varices with HCS or combined red color signs require fast response and immediate treatment intervention 3
- Red wale markings (RWM) alone may not necessitate immediate early treatment intervention, though prophylaxis is still recommended 3
Critical Prognostic Factors
Red color signs are one of the three main predictors of variceal hemorrhage:
- Variceal size (large varices have 15% yearly bleeding risk) 1
- Decompensated cirrhosis (Child B/C classification) 1
- Presence of red wale marks on endoscopy 1
The combination of these factors substantially increases bleeding risk, with variceal hemorrhage carrying at least 20% mortality at 6 weeks despite modern therapy 1
Endoscopic Documentation Requirements
During screening endoscopy, the following must be documented: 1
- Grade varices as small (<5mm) or large (>5mm) 1
- Specifically note the presence or absence of red signs (red wale marks or red spots) 1
- This documentation is essential for risk stratification and treatment decisions 1
Common Pitfalls to Avoid
- Do not delay treatment for small varices if red color signs are present—these require prophylaxis just as large varices do 1, 2
- Do not rely on red wale markings alone to assess urgency; hematocystic spots require more aggressive and immediate intervention 3
- Do not use selective beta-blockers (metoprolol, atenolol)—only non-selective beta-blockers (propranolol, nadolol) or carvedilol are effective 1
- Red color signs indicate high bleeding risk even in the absence of other risk factors, mandating prophylactic treatment 2
Surveillance After Treatment
- EVL should be repeated at 2-8 week intervals until variceal eradication 1
- Follow-up endoscopy should be performed 1-6 months after variceal eradication, then every 6-12 months thereafter 1
- Patients with red color signs who receive beta-blockers require ongoing monitoring for heart rate targets and medication tolerance 1
