BACKGROUND: Laparoscopic anatomical liver resection of segment 8 (LALR-S8) remains a challenge for anatomical laparoscopic segmentectomy. Most current reports on LALR-S8 are case series using one surgical approach, and there is a lack of multicenter data on identifying intersegmental planes using different approaches. In this study, the authors aimed to elucidate the short-term results of three different approaches for LALR-S8 for hepatocellular carcinoma (HCC), focusing on intersegmental plane determination, and to reflect on current practice regarding different approaches at multiple centers in China.
MATERIALS AND METHODS: The clinical cohort data of 122 patients who underwent LALR-S8 for HCC at seven leading centers in China were retrospectively analyzed. The surgical procedures of all approaches were summarized and standardized according to the method of the Glissonean pedicle of segment 8 identification. The postoperative short-term outcomes and oncological results of the three approaches were evaluated and compared.
RESULTS: Three approaches were used: laparoscopic ultrasonography-guided indocyanine green fluorescent positive staining approach (11/122, 9.02%), hepatic vein-guided approach (99/122, 81.15%), and Glissonean indocyanine green fluorescent negative staining approach (12/122, 9.83%). Seven (5.73%) patients experienced complications according to the Clavien-Dindo classification, and the rate of grade ≥IIIa complications was 2.46%. The R0 resection rates among the groups (margin >1 mm) and the margin width showed no statistical difference.
CONCLUSION: LALR-S8 is safe and feasible for treating HCC under standardized surgical techniques and appropriate surgical approaches. The three reported approaches had comparable short-term oncological outcomes, while the hepatic vein-guided approach was most commonly used.
