M OGILVIE SYNDRM

 A

Ogilvie Syndrome, also known as Acute Colonic Pseudo-obstruction (ACPO), is a condition characterized by a severe, non-mechanical distension of the colon. This occurs without any physical blockage or obstruction, typically leading to symptoms like abdominal pain, bloating, and constipation.

Key Points About Ogilvie Syndrome:

Etiology (Causes)

• Often associated with underlying medical conditions, especially those that affect the autonomic nervous system, which controls intestinal motility. Common causes include:

  • Post-surgical states (particularly after abdominal or pelvic surgery)

  • Trauma or injury

  • Severe illness or infections

  • Electrolyte imbalances (especially low potassium, calcium, and magnesium)

  • Medications (opioids, anticholinergics)

  • Neurological disorders affecting bowel motility

  • Endocrine disorders like hypothyroidism

Symptoms

• Abdominal distension or bloating

• Abdominal pain

• Constipation (often severe)

• Nausea and vomiting

• In severe cases, bowel perforation can occur if the condition goes untreated.

Diagnosis

• The diagnosis is largely clinical, supported by imaging such as an abdominal X-ray or CT scan showing colonic dilation with no obvious obstruction.

• Other tests may include blood tests to check for electrolyte imbalances, and in some cases, colonoscopy may be performed to rule out other causes of colonic distension.

Management

• Conservative treatment: Most cases improve with conservative management, which may involve:

  • Electrolyte correction (especially potassium, calcium, and magnesium)

  • Decompression of the colon (through nasogastric tubes or rectal tubes)

  • Discontinuing medications that could contribute to the syndrome (e.g., opioids)

  • Supportive care (hydration and pain management)

• Pharmacological treatment: In some cases, medications such as neostigmine, a cholinergic agent, may be used to stimulate bowel motility.

• Surgical intervention: Rarely, surgery may be necessary if there are complications like bowel perforation, or if conservative treatments fail.

Prognosis

• With timely diagnosis and treatment, the prognosis is generally good, with most patients recovering within a few days to weeks.

• However, complications like bowel perforation can lead to significant morbidity if left untreated.

Risk Factors:

• Older age

• History of surgery, especially abdominal or pelvic surgery

• Severe illness (e.g., sepsis)

• Use of opioids and other medications that slow gut motility
