These findings gave rise to a delayed postoperative ileus or an early short bowel obstruction at a possible location immediately adjacent to the ostomy (Fig. 1) and a nasogastric feeding tube was placed.
CT images with IV contrast on postoperative day 7. Arrow points to the distended bladder mechanically compressing the ileal segments at the abdominal wall aperture of the loop ileostomy.

These findings were thought to be the cause of small bowel obstruction at this level before the ileostomy (Fig. 2).
Abdominal X-rays before (left, postoperative day 4) and after (right, postoperative day 8) urinary catheterization on postoperative day 7, which relieved the mechanical obstruction caused by overdistended bladder.

A consequent abdominal X-ray the next day confirmed the relief of the mechanical obstruction caused by the overdistended bladder (Fig. 3).
