Stoma necrosis is most likely to occur within how many days after surgery?

• A. In the second week
• B. In the first five days post-op
• C. After the first month
• D. One year after operation

Answer: (B)

Stoma necrosis happens when the blood supply to the newly formed stoma is compromised, so tissue viability is decided in the immediate postoperative period. Edema, tension at the stoma site, twisting, or underlying vascular issues can limit perfusion right after surgery, and these problems typically manifest within the first few days. That early window—generally the first five days after surgery—is when necrosis is most likely to become evident, often within the first 24 to 72 hours. This is why careful observation of the stoma during the early postoperative days is crucial. Late occurrences beyond the first week or month are much less common and usually point to other factors rather than the initial perioperative perfusion problem.
