The visualization and local staging of ampullary cancer by the endoscopic ultrasonography is very good, visualization not hamperd by intraluminal gas. We studied the diagnostic usefulness of endoscopic ultrasonography on ampullary cancer.
Twenty-six cases of histologically proven ampullary cancer were performed abdominal ultrasonography (US), abdominal computed tomography (CT), and then endoscopic ultrasonography (EUS), and after then endoscopic retrograde cholangiopancreatography (ERCP), prospectivelly.
The rate of visualization of ampullary cancer was 11.5% in US, 19.2% in CT, 100% in EUS, and 100% in ERCP. Accuracy of EUS in the correct determination of depth of invasion (T stage) and lymph node metastasis (N stage) in surgically resected ampullary cancer was 83.3% in T stage and 78.8% in N stage. Conclusion: Endoscopic ultrasonography is considerably superior to US and CT in the visualization and local staging of the ampullary cancer.
