Ogilvie syndrome is also known as acute colonic pseudo-obstruction (ACPO)
Defined as a large bowel obstruction (LBO) in which no obstructing lesion can be identified
No definite etiology identified: suspected to develop secondary to a disbalance of colonic autonomic regulatory control
Predisposing factors: recent surgery, underlying neurologic disorders, critical illness
First described in 1948 by Sir Ogilvie, in two patients with retroperitoneal malignancy and acute colonic pseudo-obstruction

Signs, symptoms and radiographic appearance of acute large Bowel obstruction but no evidence of distal colonic obstruction
Massively dilated colon (>10cm)
- At risk for perforation, peritonitis and death

Varies, requires surgical consultation
- May resolve with conservative treatment or require colonoscopic decompression or operative management
