The Role of Imaging in the Pre‐ and Postoperative Evaluation of Inguinal Hernia

Inguinal hernia repair is the most frequently performed surgical procedure. Imaging has a fundamental role in initial assessment and postoperative evaluation of inguinal hernias. Clinical implications of radiology in the preoperative setting include diagnosis of occult/complicated hernias and enhancement of diagnostic certainty. Postoperatively, imaging may assist the detection and characterization of complications. Familiarity with the normal appearance of the postoperative groin area and surgical techniques is required to avoid misinterpretation. This pictorial essay provides an overview of the expected postoperative imaging findings and highlights the role of imaging in the pre- and postoperative evaluation of inguinal hernias, with emphasis on ultrasonography.
