Laparoscopic liver tumour resection with the argon beam

Area of Science:

• Hepatobiliary Surgery
• Minimally Invasive Procedures
• Surgical Oncology

Background:

• Liver resections are crucial for treating liver lesions, both benign and malignant.
• Minimally invasive techniques like laparoscopy are increasingly adopted for liver surgery.
• Argon beam coagulation is a common hemostatic tool in liver surgery.

Purpose of the Study:

• To report the initial experience with laparoscopic liver resections using mechanical fragmentation, hydrojet dissection, and argon beam coagulation.
• To evaluate the safety and efficacy of this technique for minor liver resections.
• To identify potential complications and necessary precautions.

Main Methods:

• Four minor liver resections were performed, including one malignant and three benign lesions.
• Dissection was achieved using mechanical fragmentation and hydrojet.
• Hemostasis was managed with argon beam coagulation and vessel clipping.

Main Results:

• Three patients underwent successful laparoscopic procedures with rapid discharge and uneventful recovery.
• One patient with hepatocellular carcinoma experienced intraoperative cardiac arrest, likely due to gas embolism.
• The operation was converted to an open approach after resuscitation, with successful completion.

Conclusions:

• Laparoscopic liver resection with mechanical fragmentation, hydrojet, and argon beam coagulation is feasible for minor resections.
• Careful management of argon gas flow is essential to prevent excessive intra-abdominal pressure and potential gas embolism.
• Awareness of hepatic vein injury risk is crucial to avoid gas embolism during argon beam coagulation.
