What is a risk factor for the development of a pseudo-stoma?

1. Limited drainage from the wound

2. No history of malignancy

3. Purulent drainage with evidence of abscess

4. Absence of suture in the fistula tract

The correct answer is: Purulent drainage with evidence of abscess

The development of a pseudo-stoma can be closely associated with the presence of purulent drainage and evidence of an abscess. This situation often indicates a significant inflammatory response and infection in the surrounding tissues. When there is an abscess, it can lead to tissue necrosis, which may create openings and alter the normal healing process of a stoma site. As the infection progresses and tissue integrity is compromised, it increases the likelihood of a false stoma forming due to the pathological changes in the area. Conversely, limited drainage from the wound does not inherently increase the risk of a pseudo-stoma, as adequate drainage may help to prevent infection. A lack of malignancy doesn't influence the development of a pseudo-stoma either, since it is more associated with infections and complications following surgical procedures. Finally, the absence of suture in the fistula tract is not a direct risk factor for pseudo-stoma formation, as other underlying factors such as infection play a more critical role. Thus, purulent drainage with evidence of abscess is a clear indicator of an increased risk for developing a pseudo-stoma.
