Case Discussion

Small bowel obstruction is a common surgical presentation.

CT is the first line investigation on many levels.

The commonest cause of obstruction is adhesions.  This is something radiologists cannot directly see on CT, but the indirect signs are indicative.

The is a textbook appearance of an adhesional related transition point.

It is always of educational merit and professionally rewarding to follow up operative findings of reported studies.
