Summary
Laparoscopic ultrasound (LUS) allows accurate liver resections, comparable to open surgery. This minimally invasive technique demonstrated safety and efficacy in a study of 55 patients, with low complication rates.
Area of Science:
- Hepatobiliary Surgery
- Minimally Invasive Surgery
- Surgical Oncology
Background:
- Intraoperative liver ultrasound is crucial for staging and guiding liver resections.
- Laparoscopic ultrasound (LUS) is expected to offer similar performance benefits in minimally invasive liver surgery.
Purpose of the Study:
- To evaluate the feasibility and accuracy of laparoscopic ultrasound-guided liver resections.
- To compare outcomes of LUS-guided resections with traditional open surgery.
Main Methods:
- LUS was used to identify tumor-vasculo-biliary relationships and map vascular planes.
- Parenchymal transection was performed, dividing vessels identified during LUS.
- Data collected on conversion rates, patient demographics, resection types, operative details, and outcomes.
Main Results:
- A laparoscopic approach was attempted in 8.2% of liver resections (61/742), with a 9.8% conversion rate, unrelated to complications.
- 55 patients underwent LUS-guided resections for benign (11) or malignant (44) lesions.
- Low postoperative complication rates (7.2%) and no liver-related morbidity were observed, with a median hospital stay of 5 days.
Conclusions:
- Laparoscopic ultrasound-guided liver resections are accurate and feasible.
- The technique offers comparable results to open surgery with minimal invasiveness.
