Background |
Although a right hepatectomy (RH) traditionally has been performed for liver tumors infiltrating the main trunk of the right hepatic vein (RHV), the presence of drainage veins of the posterior section (DVPS) beside the RHV provides a chance to preserve their draining area even if the main trunk of the RHV is removed.
Methods |
Since 2005, we systematically have performed DVPS-preserving hepatectomies whenever possible. In the present study, we describe our experience treating 12 consecutive patients who underwent this procedure.
Results |
We performed the following types of liver resections concomitant with the main trunk of the RHV without packed red cell transfusion, liver failure, or 90-day mortality: extended right anterior sectionectomy in 2 patients, extended segmentectomy 7 in 3, extended segmentectomy 8 in 2, and partial resection of segment 7 in 2 and segment 8 in 3. Postoperative morbidity was observed in 4 (33%) cases, all of which had pleural effusion requiring a tap. A free resection margin was obtained in all patients.
Conclusions |
This procedure could be a useful alternative to RH, providing a chance for radical liver resection with minimal parenchymal sacrifice in selected patients with DVPS.
