Acute cholangitis detected ectopic ampulla of Vater in the antrum incidentally: A case report

Figure 1 Computed tomography scan of the abdomen demonstrated gas retention in the intrahepatic ducts, suggesting pneumobilia.

Figure 2 There was a capsule-like foreign body approximately 1 cm × 2 cm in size at the gastric antrum and peri-pyloric region.

Figure 3 Orifice present over the pyloric ring in stomach noted after removal of a foreign body. An ectopic ampulla of Vater was suspected.

Figure 4 Cholangiography. The wire-guided catheter was inserted through the endoscope into the ectopic orifice at the pyloric ring.
