A 69-year-old man was referred to us in March 2014 because of a positive fecal occult-blood test. He had accidentally swallowed a press-through package (PTP) 4 days previously. Computed tomography showed multiple sigmoid colon diverticula, with the PTP nearby. Lower gastrointestinal endoscopy was attempted, but scope insertion was precluded by strictures caused by the diverticula. An upper endoscope (GIF-XQ240) was inserted. The PTP was found proximal to the stricture, but was difficult to remove endoscopically. The patient was transferred to the Department of Surgery to undergo laparoscopic sigmoidectomy. An accidentally swallowed PTP is often detected as an esophageal foreign body, with increasing frequency. A PTP rarely reaches the colon. PTP in the colon is often diagnosed after perforation. Invention of a better shape of PTP is desired, and medical staff should also pay attention.
