Successful endoscopic mucosal incision and enucleation of an implanted press‐through package sheet in the esophageal wall

A94-YEAR-OLDWOMAN with dementia was admitted to our hospital because of hematemesis and melena. We performed an endoscopic examination and found an elevated submucosal tumor-like lesion in the thoracic esophagus revealing a trace of a press-through package (PTP) sheet on top of it (Fig. 1a,b). Computed tomography (CT) examination revealed a PTP sheet in the thoracic esophagus near the aortic arch without free air in the mediastinum (Fig. 2). Her son stated that she might have swallowed the PTP sheet approximately six months ago.
