How Dr. Nghia Nguyen Diagnoses Ampullary Adenocarcinoma?
Dr. Nguyen uses a step-by-step approach:
Medical History
He asks about your symptoms—especially epigastric pain, changes in digestion or stool color, weight loss, and any family history of GI cancers.
Physical Exam
He gently palpates your abdomen to check for tenderness, masses, or signs of bile duct obstruction.
Blood Tests
Lab work evaluates liver enzymes, bilirubin levels, pancreatic markers, and rules out other causes of jaundice.
Imaging
Abdominal ultrasound to detect bile duct dilation or masses.
CT scan or MRI for detailed views of the ampulla of Vater and surrounding structures.
Endoscopic Ultrasound (EUS) & Biopsy
An endoscopic ultrasound pinpoints the lesion and a tiny tissue sample confirms the diagnosis under the microscope.

Frequently Asked Questions
How is ampullary adenocarcinoma different from pancreatic cancer?
Ampullary cancer starts at the ampulla of Vater, not inside the pancreas. While symptoms can overlap, each requires a distinct diagnostic workup and treatment plan.
Can I eat normal food during treatment?
You may need to modify your diet to manage symptoms and support healing. Dr. Nguyen and a dietitian will work with you to create a meal plan that's both safe and nourishing.
What is recovery like after surgery?
Most patients stay in the hospital 5-7 days after minimally invasive surgery; open procedures typically require 10-14 days. Full recovery may take several weeks, depending on your overall health and the surgery performed.
Are there clinical trials for ampullary adenocarcinoma?
Yes. Dr. Nguyen collaborates with leading Houston research centers to identify trials you may qualify for, discussing potential benefits, risks, and eligibility criteria.
How often do I need follow-ups?
Follow-up visits are generally scheduled every 3-6 months for the first two years, then annually thereafter, to monitor for recurrence and manage any long-term effects.
Will insurance cover my care?
Most major insurance plans cover evaluation and treatment for ampullary adenocarcinoma. Our team will assist you in verifying benefits, understanding coverage details, and exploring financial options.
