Abstract
Background
Laparoscopic anatomical resection of caudate lobe remains poorly described due to deep location and connection with major vascular structures. The anterior transparenchymal approach might be safter and provide a better surgical view in cirrhotic cases.1,2 This report demonstrated this approach for anatomic laparoscopic resection of paracaval portion and segment eight (S8) for HCC in an HCV-related cirrhotic patient.
Methods
A 58-year-old man was admitted. The preoperative magnetic resonance imaging indicated that the mass with pseudo capsule was located in paracaval portion and S8 closed to IVC, RHV, and MHV with atrophic left lobe. The preoperative ICG-15R test was 16.2%. In this regard, right hemihepatectomy combined with caudate resection was aborted. We decided to perform an anatomical resection via anterior transparenchymal approach to reserve liver parenchyma as much as possible.3,4
Results
After right lobe mobilization and cholecystectomy, the anterior transparenchymal approach was performed along Rex-Cantlie line by using Harmonic (Johnson & Johnson, USA). With the dissection and clamping of the Glissonean pedicles of S8, anatomical segmentectomy was performed according to the ischemic line and parenchymal transection was performed along hepatic veins. Finally, paracaval portion combined with S8 was en bloc resected. The operating time was 300 minutes with 150 ml of blood loss. The histopathologic report demonstrated the mass as HCC with negative resection margin. Furthermore, it showed a medium-to-high differentiation with no MVI and no microscopic satellite.
Conclusions
The anterior transparenchymal approach for anatomic laparoscopic resection of paracaval portion and S8 might be a feasible and safe option for severe cirrhotic cases.
