Extrahepatic Glissonean approach for laparoscopic major liver resection (with video)

Abstract

Although recent technological developments and improved endoscopic procedures have further spread the application of laparoscopic liver resection, laparoscopic major liver resection remains a highly specialized field because there are major technical difficulties, such as hilar dissection and pedicle control. The entire length of the primary branches of the Glissonean pedicle and the origin of the secondary branches are located outside the liver. In contrast, the trunks of the secondary branches and more peripheral branches run inside the liver. The right, left, anterior, or posterior Glissonean pedicle can thus be tied and divided en bloc extrahepatically during open anatomical liver resection. Each Glissonean pedicle can be easily and safely encircled and divided en bloc extrahepatically during laparoscopic anatomical liver resection using an Endo Retract Maxi or Endo Mini-Retract. This report describes a novel technique by which the extrahepatic Glissonean approach appears to be both feasible and safe for the performance of laparoscopic major liver resection.
