Efficacy Evaluation of Microwave Ablation Assisted by Diaphragm Hydrodissection for Hepatocellular Carcinoma and Comparative Analysis With Surgical

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.

Inclusion Criteria:Patients with Child-Pugh grade A or B liver function.Single hepatic lesion with a maximum diameter ≤ 5 cm.The lesion is located in the subphrenic region with a distance ≤ 10 mm from the right diaphragm.

Exclusion Criteria:Presence of extrahepatic metastasis or other concomitant malignant tumors.Presence of severe cardiac, pulmonary, or renal dysfunction.Platelet count < 50×10⁹/L with irreversible coagulation disorders. Patients with incomplete imaging or clinical medical data.
