Answer
Ogilvie's syndrome / Acute colonic pseudo-obstruction (ACPO)
Syndrome of decreased GI motility believed to be an autonomic imbalance (specifically, parasympathetic suppression) predominantly in the cecum and right colon. ACPO is also commonly due to narcotic overuse / abuse.

- Mechanical large bowel obstruction
- Toxic megacolon / colitis
- Ileus
Abdominal XR:
- Gaseous distention without fluid levels (UNLIKE obstruction)
- Small bowel dilation is typically absent (UNLIKE ileus)
- Preserved haustral markings and smooth inner contour (UNLIKE colitis)
Treatment:
- Treat underlying cause (e.g., discontinue narcotics)
- Neostigmine
- Therapeutic Colonoscopy
- Surgical decompression (if severe)
