The stomach and duodenum

Abstract

Over the last 15 years, there has been a dramatic increase in the number and range of indications for gastric surgery as a consequence of the introduction of laparoscopic techniques, changes in the incidence and location of gastric cancer, and the burgeoning demand for bariatric surgery. As these techniques have developed, some older surgical procedures have now been superseded or abandoned altogether. However, radiologists need to be aware of the whole gamut of surgical procedures on the stomach, including those that are no longer performed, in order to identify normal postoperative anatomy and also any complications from historical procedures, particularly when medical records may no longer be available. We will address this chapter by indication for surgery: gastroesophageal reflux and hiatus hernia, gastric resection, other gastric surgery for peptic ulcer disease, bariatric surgery, duodenal resections, and surgery for peptic ulcer disease.
