In addition to intravenous contrast, 500 ml of 5% Gastrografin was given 30 minutes before image acquisition. This has leaked from the small bowel in the pelvis into a cavity, which itself communicates with the anterior abdominal wall at the lower end of the midline laparotomy wound. Oral contrast is seen within the wound itself as well as a drainage bag overlying the abdominal wall. The bowel loops in the lower abdomen and pelvic look thick-walled, raising the possibility that there is ischaemia. Further thick-walled collections developing in the pelvis.
