RT Journal Article SR Electronic T1 Late presentation of an intra-abdominal foreign body JF Canadian Journal of Surgery JO CAN J SURG FD Canadian Medical Association SP 305 OP 307 VO 40 IS 4 A1 Quantz, Mackenzie A. A1 Brown, Rea YR 1997 UL http://canjsurg.ca/content/40/4/305.abstract AB Bowel obstruction by a foreign body is rare. The authors describe the case of a 77-year-old woman who had small-bowel obstruction due to a foreign body 40 years after a transabdominal hysterectomy. A loop of small bowel had herniated through a metal ring and had become necrotic. The ring and involved bowel were excised and the patient’s clinical course was uncomplicated. The original purpose of the ring remains a mystery. The time frame between the introduction of a foreign body and the occurrence of symptoms in this case appears to be the longest ever reported.
