Background
Laparoscopic hepatectomy for tumors close to the major hepatic veins (HVs) is a technically demanding procedure that is relatively contraindicated. We investigated this surgical technique and the outcomes of intraparenchymal identification of the major HVs using the ventral approach in pure laparoscopic hepatectomy for tumors close to the major HVs.
Methods
In the present study, tumors < 10 mm from the major HVs were defined as lesions in proximity to the major HVs. The cranio-ventral part of the liver parenchyma along the targeted major hepatic veins was opened to facilitate an open cutting plane. After a wide exposure of the surgical plane, the targeted major HVs were identified.
Results
Thirteen patients with tumors close to the major HVs underwent laparoscopic hepatectomy. The median operative time was 260 min (range, 160–410 min), while the intraoperative blood loss was 100 mL (range, 30–310 mL). The median Pringle maneuver time was 45 min (range, 40–75 min). The median tumor size was 50 mm (range, 17–140 mm), and the median tumor margin was 4 mm (range, 0–10 mm). Three patients (23.1%) experienced minor postoperative complications. The median postoperative hospital stay was 7 days (range, 4–25 days).
Conclusions
Pure laparoscopic hepatectomy for tumors close to the major HVs is technically feasible in selected patients. Intraparenchymal identification of the major HVs using the ventral approach achieves transection plane accuracy and avoids inadvertent injury to the major HVs.
