Abstract
We present a case of perforation of the sigmoid colon following transanal insertion of foreign bodies.
The patient was a 59-year-old man with previous histories of undergoing transanal removal of a rectal foreign body and two open surgeries to remove foreign bodies. This time he inserted balls into the anus but he could not evacuate them by himself. When he was seen at the hospital, he complained of a abdominal fullness but did not of abdominal pain. Abdominal simple x-ray examination revealed free air and thus emergency operation was performed. Upon laparotomy, two round foreign bodies with the diameter of 10cm and 20cm respectively were impacted in the sigmoid colon, and a perforation 4cm in diameter was identified. The perforated site was covered with a 10-cm vinyl ball so that no defluxion of feces was confirmed. We removed three foreign bodies by expanding the perforated site and the perforated site was treated by simple closure. He was discharged alive 8 days after the operation. To our knowledge this is the 8th reported case of sigmoid perforation following transanal insertion of foreign body in Japan.
