Managing Adhesive Small Bowel Obstruction Without Peritonitis, Strangulation, or Bowel Ischemia
When a patient presents with adhesive small bowel obstruction and there are no signs of peritonitis, strangulation, or bowel ischemia, a structured non-operative strategy is indicated as the first-line approach.
This protocol addresses adhesive small bowel obstruction in the specific setting where peritonitis, strangulation, and bowel ischemia are absent. Non-operative management should always be attempted first in this population. The presence of peritonitis, strangulation, or ischemia are contraindications to a non-operative course and fall outside this protocol.
The protocol follows a structured non-operative pathway that incorporates bowel decompression, intravenous supportive measures, and a sequential contrast-based diagnostic assessment. The complete components, sequencing, and decision criteria are detailed in the full protocol.
Resolution is confirmed when contrast reaches the colon on abdominal X-ray at the scheduled follow-up, indicating clearance of the bowel obstruction.
- Non-operative management should always be tried in patients with adhesive small bowel obstruction, unless there are signs of peritonitis, strangulation, or bowel ischemia.
- Contraindications for non-operative treatment include peritonitis, strangulation, and 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.
- Optimal diagnostic work-up should include CT scan in the assessment and water soluble oral contrast. In the absence of the need to perform immediate surgery, a follow-up abdominal X-ray should be made after 24 h.
- If the contrast has reach the colon, this is indicative for resolution of the bowel obstruction.
