Summary
A new hookwire technique allows surgeons to precisely locate small hepatocellular carcinomas (HCCs) previously undetectable by ultrasound. This enables minimally invasive laparoscopic surgery for improved treatment of these challenging liver cancers.
Area of Science:
- Hepatobiliary surgery
- Diagnostic imaging
- Minimally invasive procedures
Background:
- Computed tomography (CT) advancements can detect small hepatocellular carcinomas (HCCs) missed by sonography.
- Surgical removal of these small HCCs is challenging due to difficulties in precise tumor localization.
- Chemoembolization is a common treatment for HCC, but recurrence can occur.
Observation:
- A novel technique using preoperative CT-guided hookwire placement was employed for tumor localization.
- A 68-year-old male patient with recurrent HCC had two small lesions (<10 mm) in liver segment III, visible only on Lipiodol CT.
- A hookwire was successfully inserted into the tumor using a 21-gauge needle under CT guidance.
Findings:
- The hookwire served as the sole indicator of tumor location during laparoscopy.
- Laparoscopic surgery was performed, with the liver tissue around the hookwire coagulated.
- The patient experienced an uneventful postoperative recovery, with complete tumor ablation confirmed.
Implications:
- CT-guided hookwire placement offers a viable solution for localizing small hepatic lesions for laparoscopic surgery.
- This technique enhances the feasibility of minimally invasive surgical treatment for early-stage or recurrent HCC.
- Improved tumor localization can lead to more effective and less invasive surgical outcomes for liver cancer patients.
