Some of the key and/or interesting findings in the new American Society for Gastrointestinal Endoscopy guideline on management of volvulus and acute colonic pseudo-obstruction (ACPO) are:
- Endoscopy with a decompression tube, if possible, is still a first-line treatment for uncomplicated sigmoid volvulus, but surgical consultation should be obtained in the index admission because of high recurrence rates.
- Cecal volvulus should be managed surgically from the outset, as there is a high risk of perforation with endoscopy.
- In uncomplicated ACPO, conservative therapy (eg, withdrawing offending drugs, correcting underlying risk factors) is appropriate for 48 to 72 hours, with administration of neostigmine to those without a contraindication (2 mg over 3-5 minutes) in a monitored setting and a second dose if the first dose fails.
- Several studies suggest that continuous infusion of neostigmine by subcutaneous or intravenous routes may be superior to the usual bolus methods.
- Patients who failed neostigmine therapy should undergo colonoscopic decompression by an expert endoscopist, using nonopioid sedation, carbon dioxide, and decompression tube placement.
