Summary
Sharp liver transection using a scalpel is as safe as the clamp crushing technique for liver resection, with similar blood loss and mortality. This method offers improved tumor-free margins, especially when narrow margins are expected.
Area of Science:
- Hepatobiliary Surgery
- Surgical Techniques
- Oncology
Background:
- Parenchymal liver transection is a critical step in liver resection.
- This stage carries risks of significant bleeding and injury to liver structures.
- Comparing sharp transection with the clamp crushing technique is essential.
Purpose of the Study:
- To compare the safety and efficacy of sharp liver parenchymal transection with the clamp crushing technique.
- To evaluate outcomes such as blood loss, operative time, and margin status.
Main Methods:
- A prospective randomized study involving 82 patients undergoing hepatectomy.
- Patients were divided into sharp transection (n=41) and clamp crushing (n=41) groups.
- Key metrics recorded included warm ischemic time, blood loss, transfusions, complications, and tumor-free margins.
Main Results:
- Both techniques showed similar warm ischemic times, operative times, blood loss, and transfusion requirements.
- Overall complication rates were comparable (44% vs 39%).
- Sharp transection resulted in significantly wider tumor-free margins (12 mm vs 8 mm).
Conclusions:
- Sharp liver parenchymal transection is a safe alternative to clamp crushing regarding blood loss and mortality.
- While technically demanding, it is recommended for achieving wider tumor-free margins, particularly in cases with anticipated narrow margins.
