Summary
Intraoperative ultrasound (IOUS) is crucial for liver surgery, enabling parenchyma-sparing resections to reduce liver failure risk. This technique allows for radical yet conservative surgery, improving cure chances for more patients.
Area of Science:
- Hepatobiliary Surgery
- Surgical Oncology
- Medical Imaging
Background:
- Hepatic surgery without parenchyma-sparing strategies poses significant risks of postoperative liver failure.
- Maximizing functional liver parenchyma preservation is critical for patient survival and surgical outcomes.
Purpose of the Study:
- To highlight the pivotal role of intraoperative ultrasound (IOUS) in modern hepatic surgery.
- To describe novel IOUS-guided surgical maneuvers for precise, anatomically oriented liver resections.
- To emphasize the importance of IOUS for achieving 'radical but conservative surgery'.
Main Methods:
- Utilizing intraoperative ultrasound (IOUS) for disease staging and surgical guidance.
- Implementing liver inflow and outflow modulations for IOUS-guided resections.
- Performing precise, anatomically subsegmental, and segmental liver resections.
Main Results:
- IOUS enables 'radical but conservative surgery' for liver tumors, including hepatocellular carcinoma and colorectal liver metastases.
- New IOUS-guided maneuvers allow for more precise tailoring of hepatic resection areas.
- This approach expands curative treatment options for patients previously considered for palliative care only.
Conclusions:
- Intraoperative ultrasound (IOUS) is essential for parenchyma-sparing hepatic surgery.
- Advanced IOUS techniques facilitate precise anatomical resections, improving patient outcomes.
- These advancements are fundamental for modern liver surgeons to enhance curative treatment possibilities.
