What Is a Tubulovillous Adenomas?
A tubulovillous adenoma is a type of colon polyp that combines features of tubular (tube-like) and villous (finger-like) growths. While these polyps are not cancerous at first, they carry a higher risk of turning into colon cancer over time if left untreated.
Common Causes and Risk Factors
Age over 50 years
Family history of colon polyps or colon cancer
Long-term inflammatory bowel disease (ulcerative colitis or Crohn's disease)
Diet low in fiber and high in red or processed meats
Lack of regular physical activity
Smoking or heavy alcohol use
Signs and Symptoms
Often none in early stages
Bleeding from the rectum
Blood in the stool
Constipation or diarrhea
Abdominal cramps or discomfort
Unexplained weight loss
How Dr. Scott Diagnoses Tubulovillous Adenomas?
Dr. Scott uses a step-by-step approach:
Medical History and Physical Exam
He reviews your personal and family history of polyps or colon cancer, gastrointestinal symptoms (bleeding, change in bowel habits, discomfort), and any inflammatory bowel disease.
Colonoscopy
A high-resolution colonoscope is used to visualize the entire colon. Any polyps are identified, measured, and carefully removed when possible.
Laboratory Tests
Blood work checks for anemia (from chronic bleeding) and inflammatory markers. Stool tests may be done to rule out infection or occult blood.
Pathology Confirmation
All removed tissue is sent to a pathology lab. Microscopic analysis determines whether the polyp is tubular, villous, or tubulovillous and checks for dysplasia or early cancer.
Treatment
Our Team offers a full range of treatment options for tubulovillous adenomas of the colon.
1. Lifestyle and Diet Modifications
Increase intake of fruits, vegetables, and whole grains
Limit red and processed meats
Engage in at least 30 minutes of daily physical activity
Maintain a healthy weight
Avoid smoking and limit alcohol consumption
2. Medications
Low-dose aspirin or similar agents to reduce polyp risk
Calcium or vitamin D supplements when indicated
3. Minimally Invasive or Advanced Procedures
Polypectomy during colonoscopy for routine removal
Endoscopic Mucosal Resection (EMR) for larger lesions
Endoscopic Submucosal Dissection (ESD) for complex or flat polyps

Frequently Asked Questions
What is a tubulovillous adenoma?
A tubulovillous adenoma is a colon polyp that combines tube-shaped (tubular) and finger-like (villous) structures. While not cancerous initially, it can progress to cancer if left untreated.
How risky is a tubulovillous adenoma?
This type of polyp carries a higher risk of malignancy than purely tubular polyps, especially when high-grade dysplasia is present.
How is high-grade dysplasia in a polyp treated?
Polyps with high-grade dysplasia are typically removed during a colonoscopy using techniques like polypectomy, EMR, or ESD, followed by regular surveillance.
How often should I get a follow-up colonoscopy?
Most patients with a removed tubulovillous adenoma return for a follow-up colonoscopy every 3 to 5 years, depending on polyp features and personal risk factors.
Can I prevent new polyps from forming?
Yes. Adopting a high-fiber diet, limiting red and processed meats, exercising daily, maintaining a healthy weight, and avoiding tobacco and excess alcohol can all help reduce your risk.
