Summary
Mini-laparotomy with microwave tissue coagulation therapy (MCT) offers a less invasive approach for hepatocellular carcinoma (HCC) treatment. This method achieves wider coagulation than percutaneous methods and improves patient quality of life.
Area of Science:
- Hepatobiliary Surgery
- Minimally Invasive Oncology
- Interventional Radiology
Background:
- Hepatocellular carcinoma (HCC) treatment options include percutaneous microwave tissue coagulation therapy (PMCT) and conventional laparotomy.
- PMCT is less invasive but limited to ultrasonographically detectable tumors.
- Conventional laparotomy allows wider access but is more invasive.
Observation:
- A 57-year-old male patient with S6 subsegment HCC underwent MCT via a 12 cm mini-laparotomy.
- The procedure involved approximately 30 applications of MCT at 60 watts for 45 seconds each.
- Postoperative imaging revealed a 7 x 4 cm low-density area, indicating successful coagulation.
Findings:
- MCT with mini-laparotomy enabled a wider coagulation range compared to PMCT.
- The procedure resulted in minimal liver damage and no significant complications.
- Postoperative recovery was favorable, suggesting improved quality of life.
Implications:
- MCT with mini-laparotomy presents a viable alternative for HCC tumors not amenable to PMCT.
- This approach balances invasiveness with the ability to achieve extensive tumor ablation.
- Further research could explore the long-term outcomes and broader applicability of this technique.
