Retrograde laparoscopic resection of left side of the liver: a safe and effective way.

OBJECTIVE

The safety and feasibility of retrograde laparoscopic resection of the left side of the liver.

METHODS

Ninety-three laparoscopic left hepatic lobe cases were selected between August 2010 and August 2014 from our institution. A retrospective cohort study was performed between the antegrade partial hepatectomy group (47 cases; dissection from the first porta hepatis to the second) and the retrograde partial hepatectomy group (46 cases; dissection from the second porta hepatis to the first), to compare the length of time needed for resection, the amount of bleeding, post-operative time in the hospital, and the incidence of major complications, such as bile leakage, abdominal abscess, and post-hepatectomy hemorrhage.

RESULTS

All of the cases had a successful laparoscopic partial hepatectomy without the need for an intraoperative blood transfusion. Patients were able to ambulate on post-operative day 1 and tolerated a liquid diet on post-operative day 1 or 2. There were no statistical differences of post-operative hospital length of stay or incidence of major complications between the two groups. Both duration of resection and the amount of bleeding were less in the retrograde group than of those in the antegrade group, due to the lower incidence of hepatic vein injury in the retrograde group.

CONCLUSION

Occlusion of both the inflow and outflow hepatic vessels combined with retrograde hepatectomy from the second porta hepatis to the first, demonstrated less hemorrhage and lower incidence of hepatic veins injury during laparoscopic partial hepatectomy.
