Efficacy Evaluation of Microwave Ablation Assisted by Diaphragm Hydrodissection for Hepatocellular Carcinoma and Comparative Analysis With Surgical
The goal of this observational study is to evaluate the local efficacy and safety of hydrodissection-assisted microwave ablation for patients with hepatocellular carcinoma, and to compare its therapeutic outcomes with surgical resection for hepatocellular carcinoma. The main questions it aims to answer are:
Is hydrodissection-assisted microwave ablation safe and effective for treating hepatocellular carcinoma? How does the therapeutic effect of hydrodissection-assisted microwave ablation compare with surgical resection for hepatocellular carcinoma? Patients who receive either microwave ablation or surgical resection will Undergo a 2-year follow-up period.

Intervention / Behandling |
|---|---|
|
Hydrodissection-assisted microwave ablation cohort
Patients with hepatocellular carcinoma receiving hydrodissection-assisted microwave ablation under routine clinical care.
No study-specific intervention will be assigned by researchers.
|
For subphrenic hepatocellular carcinoma treated with microwave ablation, ultrasound-guided injection of normal saline into the diaphragm is performed during ablation to establish a hydrodissection barrier and optimise lesion visualisation.
|
|
Surgical resection cohort
Patients with hepatocellular carcinoma receiving surgical resection under routine clinical care.
No study-specific intervention will be assigned by researchers.
|
Patients with subphrenic hepatocellular carcinoma who undergo surgical resection are managed according to clinical diagnostic and therapeutic standards for hepatocellular carcinoma.
