Summary
Laparoscopic microwave coagulation therapy (LMCT) is a safe and effective minimally invasive treatment for hepatocellular carcinoma (HCC) near the liver surface. This study shows high efficacy and survival rates, with minimal complications.
Area of Science:
- Hepatobiliary Surgery
- Minimally Invasive Oncology
- Interventional Radiology
Background:
- Hepatocellular carcinoma (HCC) has several effective treatment options, including surgical resection and various ablation techniques.
- Laparoscopic microwave coagulation therapy (LMCT) is an emerging minimally invasive approach for HCC treatment.
Purpose of the Study:
- To evaluate the efficacy and safety of laparoscopic microwave coagulation therapy (LMCT) for treating hepatocellular carcinoma (HCC).
- To assess LMCT as a minimally invasive treatment option for HCC located on or near the liver surface.
Main Methods:
- LMCT was performed on 24 patients with HCC under local anesthesia, using direct laparoscopic vision and ultrasound guidance.
- Microwave electrodes with varying tip lengths (15-45 mm) were utilized.
- Treatment effectiveness was confirmed by contrast-enhanced computed tomography (CT) within two weeks post-procedure.
Main Results:
- The study treated 26 HCC nodules in 24 patients, with a mean nodule size of 20 mm.
- Complete treatment efficacy was observed in 87.5% of patients (21/24).
- A three-year survival rate of 92% was recorded, with minor complications like mild pneumothorax in three patients.
Conclusions:
- LMCT is a safe, minimally invasive, and effective single-session therapy for HCC near the liver surface.
- Direct visual guidance during LMCT enhances procedural safety and efficacy.
- LMCT offers a promising treatment option for selected HCC patients.
