Colorectal Trauma: Routine Diversion Is No Longer the Default: JAMA Surgery | September 2026

What Has Changed?

The World Society of Emergency Surgery (WSES) provides evidence-based recommendations for diagnosis, operative strategy and perioperative management of adult colon and rectal trauma.

• Contrast-enhanced CT is first-line, but a negative CT does not completely exclude bowel injury.
• Bowel-wall discontinuity, extraluminal air or active mesenteric extravasation should prompt operative evaluation.
• For suspected rectal injury, adding rigid/flexible proctoscopy to CT increases diagnostic sensitivity to approximately 97%.
• Routine rectal contrast is not recommended.
• In most stable patients, primary repair or resection with anastomosis is preferred over routine diversion.
• Low-grade colon injuries should generally undergo primary repair rather than resection.
• Diversion should be selective and driven largely by physiological instability, perfusion and damage-control circumstances.
• Extraperitoneal rectal injuries remain different: proximal diversion is generally recommended.
• Routine presacral drainage and distal rectal washout are not recommended.
• Stapled and hand-sewn anastomoses have comparable outcomes.
• Antibiotic prophylaxis should generally not exceed 24 hours.
• Early enteral nutrition is encouraged in appropriately selected patients.

Why Does It Matter?

Traditional trauma dogma often favoured colostomy based simply on the presence of colorectal injury. WSES instead emphasises physiology, contamination, tissue perfusion and the ability to achieve fascial closure.

GastroAGI Takeaway

The injured colon itself is no longer the indication for a stoma. In stable patients with viable bowel, primary repair or anastomosis should increasingly be favoured, while diversion is reserved for physiologically compromised or technically high-risk situations. Extraperitoneal rectal trauma remains an important exception.
