Stoma creation is an important surgical technique in elective and emergent alimentary tract operations, with over 100,000 in the US patients receiving colostomy or ileostomy each year . One of the most common complications of having a stoma is the development of a parastomal hernia (PH). These are often complex hernias involving various aspects of the abdominal wall musculature and fascial tissue and prove to be a significant challenge in clinical assessment and operative repair. Many factors are considered when assessing and examining PH, including size, location, bowel involvement, stoma function, concomitant hernias, mesentery, and obstruction. These factors are often difficult or impossible to assess with the physical exam alone thus evaluation with computed tomography (CT) scans is crucial for understanding, assessing, and approaching the management of PH. This chapter provides an overview of CT imaging considerations for understanding and evaluating stomas and PH.
