Summary
Thoracoscopic microwave coagulation therapy (MCT) offers a minimally invasive treatment for liver cancer (HCC) in specific liver segments. This study shows MCT effectively ablated tumors in four patients, suggesting a promising new option for complex cases.
Area of Science:
- Hepatobiliary Surgery
- Minimally Invasive Oncology
- Interventional Radiology
Background:
- Hepatocellular carcinoma (HCC) in segments VII and VIII presents treatment challenges, especially in patients with advanced liver cirrhosis or severe complications.
- Limited surgical options exist for these patients, necessitating the exploration of less invasive therapeutic approaches.
Purpose of the Study:
- To evaluate the safety and efficacy of thoracoscopic microwave coagulation therapy (MCT) for treating HCC in segments VII and VIII.
- To assess MCT as a minimally invasive alternative to hepatic resection in patients with contraindications for surgery.
Main Methods:
- Four patients with HCC in liver segments VII and VIII underwent thoracoscopic MCT.
- Tumor ablation was performed using microwave irradiation at 80 W for 60 seconds per application.
- Postoperative assessment included computed tomography (CT) to evaluate tumor ablation and margins.
Main Results:
- All four patients tolerated the procedure well, with rapid recovery and no mortality.
- Complete tumor ablation with clear margins was achieved in all patients, confirmed by CT.
- One patient experienced manageable complications, including pleural effusion and fever.
Conclusions:
- Thoracoscopic MCT is a safe and effective minimally invasive treatment for HCC in segments VII and VIII.
- This technique provides a potentially curative option for patients with advanced liver cirrhosis and severe complications, offering an alternative to limited hepatic resection.
