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

1. Clean fistula management

2. Absence of radiation history

3. Presence of a suction catheter in the fistula tract

4. Long-term dietary management

The correct answer is: Presence of a suction catheter in the fistula tract

The development of a pseudo-stoma is commonly associated with the presence of foreign objects or interventions in the area of a fistula. A suction catheter placed in the fistula tract can create pressure and irritation within the surrounding tissue, which may lead to an abnormal opening or pseudo-stoma formation. This risk arises because the suction catheter can disrupt the normal healing process and create a pathway that mimics a stoma. In contrast, factors such as clean fistula management and long-term dietary management typically emphasize the importance of maintaining a healthy environment around the fistula, which helps to minimize complications and promote healing. The absence of a radiation history does not contribute to the risk factors for pseudo-stoma development, as radiation may lead to tissue changes but is not directly related to the mechanics of a fistula or stoma formation. Understanding the effects of medical devices, like a suction catheter, on wound healing is crucial for effective management and prevention of complications related to fistulas.
