    A novel ultrasound-guided subsegmentectomy technique improves outcomes for liver cancer patients. This minimally invasive approach shows promising survival rates in hepatocellular carcinoma cases.

    Area of Science:

    • Hepatobiliary Surgery
    • Surgical Oncology
    • Medical Imaging

    Background:

    • Hepatocellular carcinoma (HCC) presents significant treatment challenges.
    • Accurate tumor resection is crucial for improving patient survival.
    • Minimally invasive techniques are increasingly preferred for liver resections.

    Purpose of the Study:

    • To describe a new operative procedure for systematic subsegmentectomy guided by ultrasound.
    • To evaluate the safety and efficacy of this novel technique in HCC patients.

    Main Methods:

    • The procedure involves operative sonography, ultrasonically guided dye injection, and hemihepatic blood occlusion.
    • Systematic subsegmentectomy was performed on 57 patients.
    • Survival data was analyzed for 35 HCC patients.

    Main Results:

    • The described operative procedure resulted in no operative mortality among 57 patients.
    • The cumulative one-year survival rate for 35 HCC patients was 80.3%.
    • Two-year and three-year survival rates were 63.3% and 52.6%, respectively.

    Conclusions:

    • Ultrasound-guided systematic subsegmentectomy is a safe and effective procedure for liver resections.
    • This technique offers encouraging survival outcomes for patients with hepatocellular carcinoma.
    • Further research should explore long-term results and broader applications.
