From the Research

Conservative management is the preferred initial approach for Ogilvie's syndrome, as it yields similar, if not superior, results to interventional management, with a lower risk of complications, as shown in a study published in 2018 1.

Key Points

  • Ogilvie's syndrome, also known as acute colonic pseudo-obstruction, is a serious condition characterized by massive dilation of the colon without mechanical obstruction.
  • Initial management includes conservative measures such as bowel rest, nasogastric tube decompression, correction of electrolyte imbalances, and discontinuation of medications that slow gut motility.
  • If conservative management fails after 24-48 hours, neostigmine is the first-line pharmacological treatment, typically administered as a 2-2.5 mg slow intravenous injection over 3-5 minutes with cardiac monitoring, as supported by a study published in 1997 2.
  • For patients who don't respond to neostigmine, endoscopic decompression may be necessary, and surgery (typically cecostomy or colectomy) is reserved for cases with perforation, peritonitis, or failure of other treatments.
  • Ogilvie's syndrome typically occurs in hospitalized patients with serious medical conditions, often following surgery or in those with electrolyte disturbances, and prompt recognition is crucial as delayed treatment can lead to perforation with mortality rates of 40-50%, as highlighted in a study published in 2017 3.

Management Approach

  • Conservative management should be the initial approach, with a focus on correcting underlying causes and managing symptoms.
  • Neostigmine should be considered if conservative management fails, with careful monitoring of cardiac function.
  • Endoscopic decompression and surgery should be reserved for cases that do not respond to neostigmine or have complications such as perforation or peritonitis.
  • Prompt recognition and treatment are essential to prevent complications and improve outcomes, as emphasized in a study published in 2016 4 and another in 2001 5.
