AIM: To explore multi-slice spiral CT (MSCT) virtual endoscopy (CTVE) in the detection of Vater's ampulla lesions. METHODS: In addition to 30 healthy volunteers, 18 cases of common bile duct stones, and 7 cases of ampullary carcinoma were scanned with MSCT including virtual endoscopy (VE) reconstruction. Patterns of the duodenal papilla were then observed, and its size was measured. RESULTS: Reconstructed images of CTVE in the volunteers showed that the normal type of the duodenal papilla was nodular in 16 cases, V-shaped in 8 cases, and Y-shaped in 6 cases. Its mean diameter was 0.84 ± 0.17 cm in the healthy volunteers; in patients with common bile duct stones of nodular type, mean diameter was 1.72 ± 0.32 cm. In ampullary cancer patients with an irregular protruded type, its diameter was 2.30 ± 0.85 cm, Overall the mean differences between the groups were statistically significant (P < 0.001). CONCLUSION: CTVE is a convenience, no-wound, and precise clinical examination mode utilizing which the shape of duodenal papilla can be observed, and size of the latter can be measured.
