However, esophagogastroduodenoscopy identified a pale, and pink-colored, foreign body stuck in the descending part of the duodenum (Fig. 2a). We first grabbed the center of the foreign body by an electrocautery snare (SD-6L-1, Olympus, Tokyo, Japan) and then gently pulled the snare forward in an antegrade fashion (Fig. 2b).
After removal, we added duodenography, which did not show any sign of leakage to the abdominal cavity or to the retroperitoneum.
