A Case of a Rectal Foreign Body in a 19-year-old Male Removed Endoscopically

The patient was a 19-year-old male. He had inserted a pencil transanally at home, and it became difficult to remove, but he did not have any symptoms. The following day, however, he had lower abdominal pain and bloody stool, so he went to his local doctor. Abdominal X-ray and CT showed a rod-shaped structure in the sigmoid colon and upper rectum. Manual removal through the anus was difficult, so the structure was removed endoscopically. The patient was discharged from the hospital on the fourth postoperative day without any abdominal symptom exacerbation.
