Bariatric surgery is increasingly performed to control morbid obesity secondary to failed medical approaches. As a result, imaging plays an important role in postoperative evaluation and management. Practical knowledge of postsurgical anatomy allows accurate interpretation of imaging findings related to normal postsurgical anatomy and common postsurgical complications.

We attained a high degree of diagnostic accuracy in patients presenting with findings suggestive of appendicitis using US as the primary imaging modality. Our false-positive appendectomy rate was 3%. Therefore, triage of the acute abdomen with US supported by CT when required has considerable merit, especially when considering that US is noninvasive and does not use ionizing radiation.
