Abstract
Background
Anatomical laparoscopic hepatolobectomy (ALH) is a difficult and challenging operation, and avoiding massive hemorrhage during parenchyma transection remains one of its major concern. Glissonean pedicle approach (GPA) has achieved great success in open liver surgery due to its simplicity and reproducibility, but it is difficult to apply in ALH for the limited vision and motion. We thus aimed to introduce a modified method to facilitate the GPA in ALH.
Methods
In this retrospective study, in 15 patients who underwent ALH (at least 2 couinaud segments), the liver parenchyma was dissected at first (LPDF) adequately under intermittent total inflow control to reveal the Glissonean pedicle (GP) sufficiently for safe and precise transection. The technical details of LPDF for different types of hepatolobectomy and a modified laparoscopic Pringle maneuver are described, and the surgical outcomes are reviewed.
Results
LPDF was applied in all patients, and intraoperative blood transfusion was not needed. LPDF facilitated GPA in ALH without any severe morbidity or mortality.
Conclusions
LPDF is a safe and effective technique, it reduces the difficulties in inflow occlusion in GPA and can promote the application of ALH. Further clinical control trails are needed to validate the superiority of LPDF compared with GPA in ALH.
