['Right superior liver resection or bisegmentectomy 7-8 is defined as the anatomical removal of segments 7 and 8 of the liver. According to recent reports, this type of resection requires the presence of a large accessory right inferior hepatic vein to drain the remaining segment 6. However, anatomic studies have shown that segment 6 has multiple veins presenting several anastomosis with the surrounding hepatic veins. Therefore, the maintenance of the veins from segment 5 that ultimately drain into the middle hepatic vein can be enough to assure venous drainage of both segments.', 'Describe an alternative technique for bisegmentectomy 7-8 using intrahepatic glissonian access in patients with absence of a large inferior right hepatic vein.', 'The technique was successfully performed in four consecutive patients without immediate or long-term venous or venous related complications.'] Is feasibility of bisegmentectomy 7-8 independent of the presence of a large inferior right hepatic vein?
