Evidence-based recommendations from a World Society of Emergency Surgery panel, published in JAMA Surgery on 23 September, cover 17 clinical questions on adult colon and rectal trauma, graded with GRADE.
For diagnosis, contrast-enhanced CT is the anchor, but a negative scan does not exclude injury; bowel wall discontinuity, extraluminal air or active mesenteric extravasation are reasons to operate. For suspected rectal injury, CT plus rigid or flexible proctoscopy reaches a combined sensitivity of about 97%, and routine rectal contrast is not advised.
For colon injuries in stable patients — including many traditionally labelled high risk — primary repair or resection with anastomosis is preferred over a routine stoma, 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 the first relook, or compounded physiological derangement. Extraperitoneal rectal injuries keep proximal diversion as the default, without routine presacral drains or distal washout. Stapled and hand-sewn anastomoses are equivalent, and antibiotic prophylaxis should not run beyond 24 hours.
The practical change for many units is the default: a stoma becomes a decision justified by physiology, not by the organ injured. Much of the underlying evidence is observational, as the panel notes. In Indian trauma practice, where penetrating abdominal injury often reaches surgeons without trauma subspecialty support, a clear physiology-based rule is particularly useful.
- In a stable patient with colon injury, favour primary repair or resection with anastomosis over a routine stoma.
- Reserve diversion for persistent vasopressor need, inability to close the fascia at relook, or severe physiological derangement.
- For suspected rectal injury, combine CT with proctoscopy rather than relying on rectal contrast.
- Divert proximally for extraperitoneal rectal injury, without routine presacral drains or distal washout.
- Stop prophylactic antibiotics within 24 hours.
Why it matters
It turns the stoma from a default into an exception that needs a physiological reason.
Don't overread it
These are consensus recommendations built largely on observational data, not new trial evidence.
