What percentage of people with a stoma are affected by parastomal hernias?

• A. 10%-20%.
• B. 5%-15%.
• C. 50%-80%.
• D. 30%-40%.

Answer: (C)

Parastomal hernia is a very common complication after creating a stoma. It happens when abdominal contents protrude through a defect at the stoma site because the abdominal wall around the opening is weaker after the operation. Because different studies define parastomal hernia in different ways and follow patients for varying lengths of time, the reported incidence ranges a lot. However, the best-supported range reflects that about half to most patients will develop one over time—roughly fifty to eighty percent. That’s why this option is the best fit: it captures the broad, real-world prevalence, including many cases that are asymptomatic and only found on imaging or later exams. The other ranges underestimate how common parastomal hernias can be, especially when considering long-term follow-up and non-symptomatic cases.
