Gastrointestinal tract perforation is an emergent condition that requires prompt surgery. Diagnosis largely depends on imaging examinations, and correct diagnosis of the presence, level, and cause of perforation is essential for appropriate management and surgical planning. Although plain radiography classically remains the first imaging modality, the high clinical efficacy of computed tomographic examination in this field has been well recognized. CT semiology is based on direct findings, including the identification of the bowel wall interruption, and indirect findings, including a pneumoperitoneum, a peridigestive infiltration, and a bowel wall thickening. These findings have different patterns according to the cause and the site of the bowel perforation. This chapter deals with the CT findings, CT pitfalls, and CT impact in the diagnosis and management of bowel perforation.
