Case Discussion

High grade adhesional small bowel obstruction at two points along the course in one location consistent with a closed loop obstruction.

Adhesions following hysterectomy are one of the typical causes of a small bowel obstruction.

Also not the common problem of getting a distended abdomen covered on plain radiograph.  You have to put the pieces of the jigsaw together in your mind to get an overall impression.
