Adhesive Small Bowel Obstruction: Operative Protocol When Non-Operative Management Has Failed
In adhesive small bowel obstruction (ASBO) without peritonitis, strangulation, or bowel ischemia, non-operative management is the established first step. When that approach does not resolve the obstruction — confirmed at the 24-hour radiological checkpoint — a structured operative protocol is indicated.
Clinical Scenario
This protocol applies to patients with adhesive small bowel obstruction in the absence of peritonitis, strangulation, and bowel ischemia. Non-operative management should always be attempted first in this population; contraindications to conservative treatment include peritonitis, strangulation, and ischemia.
When Non-Operative Management Fails
Non-operative management — nil per os, intravenous fluid and electrolyte correction, nasogastric or long intestinal tube decompression, and oral water-soluble contrast with a follow-up abdominal X-ray at 24 hours — is the first-line approach. This operative protocol is triggered when contrast fails to reach the colon on the 24-hour X-ray, indicating the obstruction has not resolved.
Next Step: Surgical Approach
When operative intervention is required, the protocol specifies surgical adhesiolysis as the procedure — with the choice between open and laparoscopic access determined by a defined set of patient-specific selection criteria. The full decision framework and operative details are available in the complete regimen.
