The use of lap seat belts has recently been recognized as a mechanism
of blunt injury to the small bowel. Patients usually present immediate
ly after injury and require urgent laparotomy. An unusual case of dela
yed small-bowel structure after conservative management of an injury r
esulting from blunt trauma is reported. A 37-year-old woman involved i
n a high-speed motor vehicle accident was managed in hospital by obser
vation. She had abdominal distension and pain., which gradually decrea
sed and allowed slow introduction of a liquid diet. She was discharged
from hospital but returned 6 weeks after injury with pain, abdominal
distension, vomiting and obstipation. Structure of an 8-cm segment of
distal jejunum was found. Resection of the involved segment with prima
ry anastomosis was curative.
