Metzenbaum-assisted liver resection: a safe and effective liver resection technique

Area of Science:

• Hepatobiliary Surgery
• Surgical Techniques
• Oncology

Background:

• Liver resections are complex procedures requiring precise parenchymal dissection.
• Minimizing blood loss and ensuring oncologic safety are critical during liver surgery.

Purpose of the Study:

• To present and evaluate a novel technique for hepatic parenchymal transection.
• Assess the safety, efficacy, and oncologic outcomes of this technique.

Main Methods:

• Retrospective analysis of 64 patients undergoing liver resection.
• Technique involves Metzenbaum scissors and clips during liver ischemia.
• Evaluation of vascular clamping, transfusion, margins, and complications.

Main Results:

• Achieved 90.6% tumor-free margins in liver resections.
• Overall morbidity was 18.8% with a 4.7% mortality rate.
• Technique facilitated safe vessel dissection and preservation/ligation.

Conclusions:

• The described technique is simple, fast, safe, and cost-effective.
• It offers limited postoperative complications and excellent oncologic outcomes.
• The method effectively protects major vascular structures during liver surgery.
