The patient underwent routine video capsule endoscopy ofr evaluation of unexplained iron deficiency anemia.Prior upper endoscopy and colonoscopy had demonstrated a hiatal hernia, however, no esophageal obstruction had previously been identified.Afer swallowing the capsule, the patient immediately experienced a choking sensation and chest discomfort.Despite drinking clear water, the capsule remained lodged in the esophagus for approximately 2-3 hours.Imaging confirmed that the capsule had not progressed beyond the esophagus.Because the capsule failed to pass spontaneously, the patient was transferred to the surgical center for urgent upper endoscopy.
