What Is the Treatment of Adhesive Small Bowel Obstruction Without Peritonitis, Strangulation, or Bowel Ischemia?
When a patient presents with adhesive small bowel obstruction (ASBO) and shows no signs of peritonitis, strangulation, or bowel ischemia, immediate surgery is not required. A non-operative approach is the recommended first-line strategy for this specific presentation.
Clinical Scenario
This protocol covers adhesive small bowel obstruction in the absence of peritonitis, strangulation, and bowel ischemia — the presentation where non-operative management should always be attempted before any consideration of surgical intervention.
Treatment Approach (Partial Overview)
Management centres on bowel rest and intestinal decompression, combined with intravenous fluid and electrolyte support. The non-operative trial can be continued safely for up to 72 hours. The complete sequence of interventions, monitoring steps, and decision points is available in the full structured protocol.
Treatment Goal
Resolution of the bowel obstruction, confirmed by water-soluble contrast reaching the colon on an abdominal X-ray taken 24 hours after contrast administration.

- Non-operative management should always be tried in patients with adhesive small bowel obstruction, unless there are signs of peritonitis, strangulation, or bowel ischemia.
- The panel recommends a trial of non-operative management in all patients with ASBO, unless there are signs of peritonitis, strangulation, or bowel ischemia.
- The cornerstone of non-operative management is nil per os and decompression using a naso-gastric tube or long intestinal tube.
- The principles of non-operative treatment are nil per os, naso-gastric, or long-tube decompression, and intravenous supplementation with fluids and electrolytes.
- Non-operative management should further include fluid resuscitation, correction of electrolyte disturbances, nutritional support, and prevention of aspiration.
- A trial of non-operative management can be continued safely for 72 h.
- If the contrast has reach the colon, this is indicative for resolution of the bowel obstruction.
- In the absence of the need to perform immediate surgery, a follow-up abdominal X-ray should be made after 24 h.
