case_images: One day after admission, an abdominal X-ray showed that the patient had a double pigtail stent placed in the bile duct. During papilla observation, esophagogastroduodenoscopy could not locate the bile duct stent suggesting that the stent had migrated into the bile duct.

case_images: Although the abdominal radiograph showed that the patient had a double-pigtail stent with a loop diameter of approximately 24 mm (Figure 1), the stent could not be visualized during endoscopic observation of the papilla, indicating that the stent had migrated into the bile duct where its looped end was likely caught within the papilla (Figure 1).
case_images: Endoscopic papillary large balloon dilatation (EPLBD) was performed, which expanded the papilla to a diameter of 12 mm.

case_images: Therefore, endoscopic papillary large balloon dilatation (EPLBD) was performed, wherein the papilla was dilated to a diameter of 12 mm (Figure 2).
case_images: Following endoscopic papillary large balloon dilatation, grasping forceps were inserted into the bile duct, and the stent was successfully grasped and retrieved through the papilla.

case_images: Grasping forceps were inserted into the bile duct, and the stent was successfully grasped and retrieved through the papilla (Figure 3).
