Summary
A bipolar vessel sealing device effectively controls bleeding and bile leakage during liver resection in patients with normal liver parenchyma. However, it is not recommended for cirrhotic livers due to a higher risk of complications.
Area of Science:
- Hepatobiliary Surgery
- Surgical Technology
- Minimally Invasive Procedures
Background:
- Liver resection carries risks of blood loss and bile leakage, impacting patient outcomes.
- Effective surgical techniques are crucial for minimizing intraoperative and postoperative complications.
Purpose of the Study:
- To evaluate the efficacy and safety of a bipolar vessel sealing device for liver transection.
- To determine if the device can achieve adequate hemostasis and bile stasis without routine inflow occlusion.
Main Methods:
- Fifty patients underwent liver resection using a bipolar vessel sealing device with a clamp crushing technique.
- Inflow occlusion was selectively used, not routinely.
- Hemostasis was achieved solely with the bipolar device in most cases.
Main Results:
- The device was effective in 45 patients (90%), failing in 5 cases with cirrhotic livers.
- Median blood loss was 490 ml, with 16% requiring transfusions.
- Postoperative complications occurred in 24% of patients; no bile leaks or abscesses were reported.
Conclusions:
- The bipolar vessel sealing device is a useful tool for standard liver resections with normal liver parenchyma.
- Good hemostasis and bile stasis were achieved in non-cirrhotic patients.
- The device's use should be avoided in patients with cirrhotic livers.
