Modified hepatic vascular occlusion facilitates hepatectomy for malignant hepatic tumor in laparoscopy.
OBJECTIVE
The parenchymal transection and bleeding are important problems in laparoscopic hepatectomy (LH). The study aimed to evaluate the feasibility and safety of LH for a malignant hepatic tumor (MHT) with hepatic vascular occlusion (HVO) only using a monopolar electrocautery.


METHODS
A total of 31 patients' profiles, operative data, clinical outcomes, pathologic findings, and follow-up information were collected who underwent LH with HVO.


RESULTS
The median operative time was 176 minutes and the median postoperative hospital stay was 9 days. The median estimated blood loss was 310 mL. The median tumor size was 4.6 cm and the median surgical margin was 12 mm.The ischemia injury to the liver in patients subjected to selective HVO was less than that in patients subjected to the Pringle maneuver.


CONCLUSIONS
HVO facilitates LH in transecting liver parenchyma and reduces bleeding, making LH safe and feasible only using monopolar electrocautery in selected patients with malignancies. Moreover, the selective HVO have more advantages over the Pringle maneuver in decreasing ischemic injury.
