Because IOUS always follows the preoperative imaging modalities in the diagnostic workup, its higher sensitivity should be expected and surgeons should take advantage of that. The extensive analysis from Zhang and colleagues on a large series of patients with HCC confirms that IOUS is essential for reoperation and, we may say, makes them possible. These results are encouraging and should be considered in a scientific community that too often neglects the relevance of IOUS, which is more evident in liver surgery. Indeed, detecting new lesions effects the surgical strategy, resulting in better surgical treatments and allowing for a wider range of operations. Furthermore, the potential of IOUS and its effects in liver surgery are far from being completely established. Indeed, IOUS still has a high sensitivity but a low specificity in exploring the cirrhotic liver, and the risk of overestimating or underestimating the real tumor dissemination . . .
