Intraoperative ultrasonography (IOUS) still remains a useful and occasionally a problem-solving technique in pancreatic diseases, even though its role has recently been downsized owing to preoperative imaging advances [1]. Since its introduction in the 1980s, progressive technical developments have led to an increase in the diagnostic accuracy of IOUS. The availability of scanners that provide the depiction of fine anatomic details and the detection of small lesions in real-time with excellent spatial and contrast resolution allow the widespread application of this imaging method [1, 2]. Moreover, IOUS is able to clearly show lesions not detectable with other preoperative imaging modalities, and to accurately define the extension of the tumor and its relationship with vessels, sometimes determining significant changes in the therapeutic management of patients [3]–[5]. In addition, its ability in guiding interventional procedures (i.e. biopsy, duct cannulation and drainage of abscesses or cysts) has been widely reported [2, 6]. Lastly, its impact has significantly increased since both the development of mini-invasive laparoscopic approaches, due to the impossibility for the surgeon to visually and manually inspect the affected organ and the retroperitoneum, and the recent introduction of alternative palliative treatments under IOUS-guidance [7, 8].
