Why is the size and shape of a stoma significant?

The size and shape of a stoma are significant primarily because they directly affect the fitting and comfort of the pouching system. A stoma that is well-fitting allows for a secure seal, which helps to prevent leaks and skin irritation. If the pouching system does not fit the stoma correctly, it can lead to complications such as skin breakdown around the stoma or discomfort for the patient.

Additionally, an improperly fitted pouch can result in unwanted odor and leakage, which can affect the patient's quality of life and self-esteem. Accurate fitting is essential for the wear-time of the pouching system and can influence how often a patient needs to change their pouch. Thus, understanding the stoma's size and shape is crucial for providing effective and personalized ostomy care.
