Surgeons develop and rely on a keen sense of touch to gain subtle insights about the tissues on which they operate. The accomplished surgeon easily assesses the strength of the tissue or organ, vascularity, and the presence of neoplasm or stricture. The solid organs of the abdominal cavity, however, do not lend themselves to a complete evaluation by palpation alone. Plain x-rays and fluoroscopy aid the surgeon but are limited by either their static nature or problems with radiation exposure. The explosion of videoscopic surgical techniques has distanced the surgeon from the tissues of concern, making palpation all but impossible. The introduction of intraoperative ultrasonography gave the surgeon eyes and ears where he or she once had only touch. Intraoperative ultrasonography of solid abdominal organs allows a relatively detailed view of the anatomic structures, vascular components, and the relationships of disease to anatomy-in real time. These views were not available a generation ago. Ultrasound techniques also provide another benefit: they may also allow the surgeon to determine if the resection or operation has been completed successfully. The ultrasound machine is not new to the operating room. Modern low-profile transducers (in a variety of configurations) have given the intraoperative sonographer greater freedom of movement, more flexibility, and greater accuracy in the evaluation process than before (Fig. 8.1). A wide variety of scanning frequencies and software are now available. These advances allow the surgeon to match depth of penetration with scanning resolution for each patient.
