Summary
The novel "corkscrew technique" simplifies liver resection for hepatic metastases by creating traction for easier ligation. This safe and efficient method ensures clear tumor margins, improving patient outcomes.
Area of Science:
- Hepatobiliary Surgery
- Surgical Oncology
- Gastroenterology
Background:
- Liver resection is the primary curative treatment for hepatic metastases.
- Existing techniques may pose challenges in exposing critical structures for ligation.
Purpose of the Study:
- To introduce and describe an original surgical technique, the "corkscrew technique," for liver metastasis resection.
- To evaluate the safety and efficacy of this novel approach.
Main Methods:
- The corkscrew technique involves placing radiate stitches around the tumor, creating traction and countertraction.
- This method facilitates clear exposure of structures for ligation and parenchyma separation.
- The resection area is delimited 2 cm from the tumor, with specific attention to needle diameter and stitch placement.
Main Results:
- The corkscrew technique was used in 612 patients, with an associated anatomic resection in 129.
- The study reported a low mortality rate of 1%.
- Morbidity was 16%, with a 3% reoperation rate, indicating a favorable safety profile.
Conclusions:
- The corkscrew technique is a simple, safe, and effective method for liver metastasis resection.
- It spares surgical time, minimizes blood loss, and ensures clear tumor margins.
- This technique is easily performable and offers significant advantages in managing hepatic metastases.
