Small bowel obstruction accounts for what percentage of all mechanical bowel obstructions?
80%
200 mL of Gastrografin was administered via an NGT after a preliminary film had been taken.
Results
Preliminary film. Gastrografin had been administered 24 hours previously.
Six hours after contrast administration the small bowel opacifies showing dilated loops measuring up to 5 cm. On the 11 hour film the contrast remains within the small bowel without progression into the colon and this is confirmed on the 16 hour film. Faecal material is seen within the colon. Pacemaker leads, left hip screw and costal cartilage calcification are noted.
Conclusion
Features consistent with a persistent small bowel obstruction.
