Tissue preserving hepatectomy by a vessel sealing device

Area of Science:

• Hepatobiliary Surgery
• Surgical Innovation
• Minimally Invasive Techniques

Background:

• Intraoperative blood loss and biliary leaks are significant causes of morbidity after liver resection.
• Current techniques for liver parenchyma transection carry risks of bleeding and bile leakage.
• A novel approach using the Atlas modification of the ligasure vessel sealing system is presented.

Purpose of the Study:

• To evaluate a new technique for liver parenchyma transection.
• To assess the efficacy of the Atlas modification of the ligasure system in reducing blood loss and biliary leaks.
• To determine the safety and simplicity of this alternative liver resection method.

Main Methods:

• A cohort of 10 cirrhotic patients with hepatocellular carcinoma (HCC) underwent minor liver resections.
• Twelve patients with metastatic liver disease underwent tissue-preserving hepatectomy.
• The Atlas modification of the ligasure vessel sealing system was used for liver parenchyma transection.

Main Results:

• Blood loss ranged from 120-350 ml in cirrhotic patients and 80-280 ml in patients with metastatic disease.
• No instances of postoperative biliary leakage were reported in either patient group.
• The technique demonstrated effective sealing of vessels and bile ducts during transection.

Conclusions:

• The described technique for liver parenchyma division is simple and effective.
• This method successfully prevents significant blood loss and bile leaks in minor liver resections.
• The Atlas modification of the ligasure system offers a promising alternative for liver surgery.
