Portal vein embolisation (PVE) represents the standard procedure for augmentation of the contralateral lobe before extended right hepatectomy. However, possible limitations for the percutaneous transhepatic approach exist, for example, large tumours of the right lobe. Here, we present our experiences with single-incision laparoscopic surgery-PVE (SILS-PVE) as an alternative approach for settings where percutaneous routes are technically not feasible.


A small umbilical incision is performed, and a GelPOINT Mini Advanced Access Platform (Santa Margarida, CA, USA) is placed. Staging laparoscopy is performed routinely followed by identification of an appropriate ileal segment, which is subsequently exteriorized through the small umbilical incision. A peripheral mesenteric vein is encircled and cannulated to access right portal vein branches. After sufficient embolisation of the right lobe, the peripheral vein is ligated, the single port is extracted and the umbilical wound is closed.


SILS-PVE was successfully applied in 10 patients (median age 60.5 years) between 12/2015 and 03/2018. The technique was indicated due to extensive tumours in the right lobe (n = 8), extensive hydatid cyst (n = 1) and during SILS right hemicolectomy in Stage IV colon cancer (n = 1). Mean operative time was 184 min (range 116-315). Patients were discharged on post-operative day 4 (range 2-9). Augmentation of the future liver remnant volume was assessed by computed tomography-volumetry 3-4 weeks after SILS-PVE and showed a mean relative increase of 64.95%, future remnant liver function showed a mean increase of 120.77%.


The proposed SILS-PVE represents a technically simple and safe alternative to standard percutaneous transhepatic approaches. Perioperative risks can be minimised by minimally-invasive surgery, which is of explicit importance in multimodal approaches before major hepatectomy.
