Ampullary adenoma is a non-cancerous growth found at the ampulla of Vater. This is where your bile duct and pancreatic duct join and connect to the small intestine.
He reviews your personal and family health history, genetic risk factors (e.g., FAP), and any prior GI polyps.
We measure liver enzymes, bilirubin levels, and other markers to assess bile duct and pancreatic function.
An upper endoscopy examines the ampulla directly and obtains tissue samples to confirm benign vs. malignant cells.
We document your diagnosis using ICD-10 code D13.4 (benign neoplasm of ampulla of Vater) for precise billing and follow-up.

No, but they can turn into cancer over time. That's why Dr. Chadha closely monitors or removes them depending on size, symptoms, and biopsy results.
Most cases are sporadic, but some are linked to genetic syndromes like familial adenomatous polyposis (FAP). Dr. Chadha evaluates your family history as part of the workup.
They may include jaundice, dark urine, pale stools, abdominal pain, or pancreatitis. Sometimes they are found during a test for another issue. Dr. Chadha investigates unexplained symptoms with advanced tools.
Diagnosis is usually made by endoscopy and biopsy. Dr. Chadha uses endoscopic ultrasound (EUS) and ERCP to get a clear view of the ampulla and surrounding ducts.
Endoscopic removal is often done if the tumor is small and confined. For larger or suspicious lesions, surgery may be needed. Dr. Chadha provides expert guidance on the safest and most effective option.
Yes. Dr. Chadha schedules regular surveillance endoscopies to check for recurrence or new growths, especially in patients with genetic risks.
Yes. They can block the pancreatic duct, leading to inflammation. Dr. Chadha treats both the adenoma and related complications like recurrent pancreatitis.
Most patients recover in a few days. Dr. Chadha provides dietary and medication guidance during recovery to reduce discomfort and promote healing.
