High grade small bowel obstruction, with slow gradient of oral contrast -> unopacified contents.
Oral contrast helps you to quickly target the point of obstruction, as the distal small bowel before the obstruction should only have fluid (oral contrast cannot make it that far).
Incarcerated left femoral hernia.
Notice inguinal ligament "cutting across the bowel" on coronal images.
Note relationship with inferior epigastric vessels (hernia is below).
Distal small bowel is decompressed
