Is a Colostomy Considered a Wound?
No, a colostomy is not classified as a wound—it is a surgically created opening (stoma) of the colon through the abdominal wall that serves as an artificial intestinal exit for fecal excretion. 1
Understanding the Distinction
A colostomy is fundamentally different from a surgical wound in both structure and function:
A surgical wound is defined by the WHO as "a wound created when an incision is made with a scalpel or other sharp cutting device and then closed in the operating room by suture, staple, adhesive tape, or glue and resulting in close approximation to the skin edges." 1
A colostomy is an intentionally created, permanent or temporary opening where a portion of the colon is brought through the abdominal wall to the skin surface, creating a functional stoma for fecal diversion—not a closed incision. 1, 2
Clinical Implications of This Classification
Why the Distinction Matters
The classification has important practical consequences for patient care:
Care requirements differ fundamentally: Colostomies require specialized ostomy care including appliance management, pouching systems, and wafer changes (typically every 6-7 days for colostomies), rather than wound dressing changes. 1
Complications are stoma-specific: Common colostomy complications include peristomal skin complications, stomal retraction, stenosis, prolapse, and parastomal hernia—not typical wound complications like dehiscence or surgical site infection. 3
Specialized expertise is needed: The 2023 AGA guidelines emphasize that ostomy management requires input from wound ostomy continence (WOC) nurses, reflecting the specialized nature of stoma care distinct from wound care. 1
The Surgical Incision vs. The Stoma
Important caveat: While the colostomy itself is not a wound, the surgical incision(s) made to create the colostomy are surgical wounds that require standard wound care during the perioperative period. 1 Once healed, however, the focus shifts entirely to stoma management rather than wound care.
Functional Characteristics That Define a Colostomy
Active tissue: The stoma consists of viable, functioning intestinal mucosa that continues normal physiologic activity including mucus production. 4
Permanent or temporary diversion: Colostomies serve to divert the fecal stream for conditions including colorectal cancer, diverticulitis with perforation, trauma, Crohn's disease, and fecal incontinence. 1, 5
Requires specialized appliances: Unlike wounds that heal and no longer require dressing, colostomies require ongoing pouching systems for effluent management. 1
Common Pitfall to Avoid
Do not confuse the peristomal skin (the skin surrounding the stoma) with the stoma itself. While peristomal skin can develop wound-like complications such as excoriation or breakdown requiring wound care principles, the stoma itself remains a functioning intestinal opening, not a wound. 3
