Background: Malignant biliary neoplasm is relatively common in Southeast Asia. Portal vein embolization (PVE) is a preoperative procedure to induce hypertrophy of future liver remnants. PVE can decrease the rate of post hepatectomy liver failure (PHLF). Objective: To evaluate the efficacy of preoperative PVE of biliary neoplasm patient prior to major hepatic resection. Materials and Methods: The study included 53 patients with biliary neoplasm planned for major hepatic resection and that underwent PVE between July 2013 and August 2019. Liver volumetry before and after PVE was analyzed. Operative procedure and post hepatectomy outcome were evaluated. Results: Peri-hilar type cholangiocarcinoma, Bismuth-Corlette classification IIIA was the most frequent tumor. The technical success rate of PVE is 100%. Future liver remnant (FLR) volume after PVE was significantly increased from 379.1 to 460 mL (p<0.001). Post PVE FLR over total functional liver volume (TFLV) ratio was significantly increased from 27.8% to 34.6%(p<0.001). The mean kinetic growth rate (KGR) per week was 7.1%. Twenty-four patients underwent subsequent hepatectomy, and two patients presented with PHLF. Twenty-nine patients (54.7%) did not undergo subsequent hepatectomy as planned due to advanced disease with 21 (72.4%) because of locally advanced cancer, peritoneal carcinomatosis, and N2 lymph nodes metastasis), four (13.8%) that refused surgical treatment, and three (10.3%) that were loss to follow-up. Conclusion: Preoperative PVE before major hepatic resection in biliary neoplasm patients is an effective procedure to increase FLR, FLR/TFLV ratio, and provide good KGR. However, more than half of post preoperative PVE could not be obtained hepatectomy because of the progression to advanced stage of disease.

Extended Right Hepatectomy

Colorectal liver metastases (CRLM) are the major cause of death in patients with colorectal cancer (CRC). The cornerstone treatment of CRLM is surgical resection. Post-operative morbidity and mortality are mainly linked to an inadequate future liver remnant (FLR). Nowadays preoperative portal vein embolization (PVE) is the most widely performed technique to increase the size of the future liver remnant (FLR) before major hepatectomies. One method recently proposed to increase the FLR is liver venous deprivation (LVD), but its oncological impact is still unknown. The aim of this study is to report first short- and long-term oncological outcomes after LVD in patients undergoing right (or extended right) hepatectomy for CRLM. Seventeen consecutive patients undergoing LVD between July 2015 and May 2020 before an (extended) right hepatectomy were retrospectively analyzed from an institutional database. Post-operative and follow-up data were analyzed and reported. Primary outcomes were 1-year and 3-year overall survival (OS) and hepatic recurrence (HR). Postoperative complications occurred in 8 patients (47%). No deaths occurred after surgery. HR occurred in 9 patients (52.9%). 1-year and 3-year OS were 87% (95% confidence interval [CI]: ±16%) and 60.3%, respectively (95% CI: ±23%). Median Disease-Free Survival (DFS) was 6 months (CI 95%: 4.7–7.2). With all the limitations of a retrospective study with a small sample size, LVD showed similar oncological outcomes compared to literature reports for Portal Vein Embolization (PVE).

The Future

Selective portal vein embolization (PVE) before extended liver surgery is an accepted method to stimulate growth of the future liver remnant. Portal vein thrombosis (PVT) of the main stem and the non-targeted branches to the future liver remnant is a rare but major complication of PVE, requiring immediate revascularization. Without revascularization, curative liver surgery is not possible, resulting in a potentially life-threatening situation. We here present a new surgical technique to revascularize the portal vein after PVT by combining a surgical thrombectomy with catheter-based thrombolysis via the surgically reopened umbilical vein. This technique was successfully applied in a patient who developed thrombosis of the portal vein main stem, as well as the left portal vein and its branches to the left lateral segments after selective right-sided PVE in preparation for an extended right hemihepatectomy. The advantage of this technique is the avoidance of an exploration of hepatoduodenal ligament and a venotomy of the portal vein. The minimal surgical trauma facilitates additional intravascular thrombolytic therapy as well as the future right extended hemihepatectomy. We recommend this technique in patients with extensive PVT in which percutaneous less invasive therapies have been proven unsuccessful.
