Summary
Anatomical resection of segment VIII (SVIII) for hepatocellular carcinoma (HCC) offers improved long-term survival compared to non-anatomical resection. This safe and effective surgical approach can be curative, particularly for patients with compromised liver function.
Area of Science:
- Hepatobiliary surgery
- Surgical oncology
- Gastroenterology
Background:
- Segment VIII (SVIII) resection is a complex surgical procedure.
- Limited data exists on the long-term outcomes of anatomical SVIII resection.
- This study addresses the need for comprehensive outcome evaluation.
Purpose of the Study:
- To evaluate short- and long-term outcomes of anatomical SVIII resection for hepatocellular carcinoma (HCC).
- To compare long-term outcomes of anatomical SVIII resection with non-anatomical resection.
- To assess the safety and efficacy of anatomical SVIII resection.
Main Methods:
- Retrospective comparison of patients undergoing anatomical versus non-anatomical SVIII resection for HCC.
- Data collected included operative details, postoperative complications, and survival rates.
- Indocyanine green retention rate was used to assess liver function.
Main Results:
- 154 patients had anatomical resection, 122 had non-anatomical resection.
- Anatomical resection showed significantly better 5-year recurrence-free (28.5% vs 19.4%) and overall survival (79.6% vs 64.8%) rates (P = 0.036 and P < 0.001).
- No postoperative deaths occurred in the anatomical resection group, with a major adverse event rate of 6.5%.
Conclusions:
- Complete anatomical resection of SVIII is safe and yields acceptable long-term outcomes for HCC.
- This technique can be a curative option, especially for patients with limited liver reserve.
- It may help avoid more extensive procedures like right hepatectomy.
