The World Society of Emergency Surgery panel addressed 17 questions on adult colon and rectal trauma, grading each recommendation with GRADE. The direction is consistent: patient physiology, contamination, perfusion and whether the abdomen can be closed should drive decisions, not the injured organ or any single risk factor.
On diagnosis, contrast CT is the anchor but a negative scan does not exclude injury; bowel wall discontinuity, extraluminal air or active mesenteric extravasation warrant operation. For suspected rectal injury, CT plus rigid or flexible proctoscopy reaches a combined sensitivity of about 97%; routine rectal contrast is not recommended.
On operation, primary repair or resection with anastomosis is preferred over routine diversion for most stable patients, including many traditionally labelled high risk, and primary repair alone is preferred for low-grade injuries. Diversion is reserved for persistent vasopressor dependence after damage control, failure to close the fascia at first re-look, or compounded physiological derangement. Extraperitoneal rectal injury still defaults to proximal diversion, without presacral drainage or distal washout. Stapled and hand-sewn anastomoses are equivalent, and prophylactic antibiotics should stop within 24 hours. Much of the evidence is observational, which the panel acknowledges.
- Do not rely on a negative CT to exclude colonic injury when the clinical picture suggests one
- Add proctoscopy to CT for suspected rectal injury; skip routine rectal contrast
- Repair primarily or resect and anastomose in stable patients rather than defaulting to a stoma
- Divert when vasopressors persist after damage control or the fascia cannot be closed at re-look
- Stop prophylactic antibiotics within 24 hours; no presacral drains or distal rectal washout
Why it matters
It removes several traditional high-risk labels as automatic reasons for a stoma.
Don't overread it
Most recommendations rest on observational evidence; they standardise practice rather than prove superiority.
