Intraoperative ultrasound (IOUS) has emerged as an indispensable tool in the planning and execution of hepatic resections, offering real-time visualization of liver anatomy, including tumor location, vascular structures, and surrounding parenchyma. This capability is paramount for accurately defining resection margins and effectively avoiding critical vascular structures, thereby enhancing surgical precision and patient safety [1].
The integration of IOUS into the surgical workflow provides critical real-time guidance during liver resections, significantly improving the surgeon's ability to delineate tumor margins and identify vital vascular and biliary structures. This leads to enhanced surgical precision and a reduced risk of incomplete resection, ultimately contributing to safer and more effective management of liver tumors [2].
The accurate assessment of tumor extent and its precise relationship to hepatic vasculature is of utmost importance in liver cancer surgery. IOUS greatly contributes to this by offering superior soft-tissue contrast and enabling visualization of structures that may not be clearly discernible on preoperative imaging, allowing for immediate adjustments in surgical strategy [3].
Intraoperative ultrasound is crucial for identifying satellite nodules and meticulously assessing the vascularity of liver tumors, providing information that is critical for precise resection planning. Its ability to differentiate tumor from non-tumorous liver parenchyma and map the hepatic and portal veins aids in achieving negative resection margins and preserving functional liver volume [4].
The dynamic assessment of liver anatomy and tumor extent offered by IOUS is often superior to static preoperative imaging, particularly in complex resections. This real-time feedback allows surgeons to avoid inadvertent injury to major vascular structures and biliary ducts, leading to safer and more oncologically sound procedures [5].
Intraoperative ultrasound plays a pivotal role in refining surgical margins by providing real-time imaging of the liver parenchyma and its neoplastic involvement. It aids in the precise localization of tumors, especially those that are deeply seated or not clearly demarcated on preoperative scans, thereby enabling the surgeon to achieve adequate resection planes and potentially reduce local recurrence [6].
For patients undergoing resection of liver metastases, IOUS is critical for detecting occult lesions and mapping disease distribution. Its high resolution and real-time nature facilitate accurate lesion identification, preventing intraoperative surprises and guiding the extent of resection to achieve complete tumor removal [7].
The utility of IOUS extends to guiding minimally invasive liver resections, such as laparoscopic procedures, by providing essential anatomical landmarks and tumor localization, which are more challenging in this setting. This technology enhances precision and safety, enabling the successful completion of complex resections with reduced invasiveness [8].
Intraoperative ultrasound offers a distinct advantage in delineating the precise anatomical relationship between liver tumors and major vascular structures, such as the portal vein and hepatic veins. This detailed understanding is critical for planning surgical approaches to minimize vascular complications and ensure adequate resection while preserving necessary vessels [9].
The learning curve associated with IOUS in hepatic resections is manageable, and its widespread adoption can significantly improve the safety and efficacy of liver surgery. Training surgeons in its proficient use is essential for maximizing its benefits in defining resection planes, identifying vital structures, and ultimately achieving better patient outcomes [10].
Intraoperative ultrasound (IOUS) serves as a vital adjunct in hepatic resection planning, providing real-time visualization of the liver's intricate anatomy. This includes the precise location of tumors, the course of vascular structures, and the characteristics of the surrounding parenchyma, all of which are crucial for establishing appropriate resection margins and preventing injury to major vessels [1].
During liver resections, IOUS offers indispensable real-time guidance, empowering surgeons to accurately delineate tumor margins and identify critical vascular and biliary conduits. This enhanced visualization directly contributes to improved surgical precision, a reduced likelihood of incomplete resection, and ultimately, safer and more effective management of hepatic malignancies [2].
In the context of liver cancer surgery, the meticulous assessment of tumor extent and its exact spatial relationship with hepatic vasculature is of paramount importance. IOUS significantly aids in this process by delivering superior soft-tissue contrast and revealing structures not clearly depicted on preoperative imaging, thereby facilitating immediate strategic adjustments during the operation [3].
Intraoperative ultrasound plays a critical role in identifying satellite nodules and characterizing the vascularity of liver tumors, providing essential data for accurate resection planning. Its capacity to distinguish between tumorous and non-tumorous liver tissue, as well as to map the hepatic and portal venous systems, is instrumental in achieving negative resection margins and preserving functional liver volume [4].
The integration of IOUS into the surgical environment enables a dynamic evaluation of liver anatomy and tumor extent, often surpassing the capabilities of static preoperative imaging. This is particularly beneficial in complex resections, where it helps surgeons to avoid inadvertent damage to major vascular structures and biliary ducts, thereby enhancing both safety and oncological outcomes [5].
Intraoperative ultrasound is pivotal in refining surgical margins by offering real-time imaging of the liver parenchyma and any neoplastic involvement. It assists in the accurate localization of tumors, especially those that are deeply situated or lack clear demarcation on preoperative scans, enabling the achievement of adequate resection planes and potentially lowering the risk of local recurrence [6].
For patients undergoing resection of liver metastases, IOUS is indispensable for detecting occult lesions and delineating the pattern of disease spread. Its high resolution and real-time imaging capabilities allow for precise lesion identification, preventing intraoperative surprises and guiding the extent of resection to ensure complete tumor eradication [7].
The utility of IOUS is also evident in the guidance of minimally invasive liver resections, such as laparoscopic procedures. It provides crucial anatomical landmarks and tumor localization, which are more challenging to ascertain in a laparoscopic setting, thereby improving precision and safety [8].
Intraoperative ultrasound offers a distinct advantage in precisely defining the anatomical relationship between liver tumors and major vascular structures, including the portal and hepatic veins. This detailed understanding is vital for planning surgical approaches that minimize vascular complications and ensure adequate resection while preserving essential vessels [9].
While there is a learning curve associated with the use of IOUS in hepatic resections, its widespread adoption is associated with significant improvements in the safety and efficacy of liver surgery. Adequate training for surgeons in its proficient application is essential to maximize its benefits in defining resection planes, identifying vital structures, and ultimately improving patient outcomes [10].

IOUS aids in avoiding major vessels, preserving functional liver volume, and achieving negative resection margins, leading to improved oncologic outcomes and patient safety. Its integration into surgical practice, supported by adequate training, is essential for optimizing the safety and efficacy of liver surgery and for managing both primary liver tumors and metastases.
