Abstract Background Performing major hepatectomy for patients with marginal hepatic function is challenging. In some cases, the procedure is contraindicated owing to the threat of postoperative liver failure. In this case report, we present the first case of marginal liver function (indocyanine green clearance retention rate at 15 min [ICGR15]: 28%) successfully treated with right hepatectomy, resulting in total caudate lobe preservation. Case presentation A 71-year-old man was diagnosed with sigmoid colon cancer with three liver metastases (S5, S7, and S8). All of metastatic lesions shrunk after chemotherapy, but his ICGR15 and indocyanine green clearance rate (ICGK) were 21% and 0.12, respectively. Moreover, the remnant liver volume was only 39%. Therefore, portal venous embolism (PVE) of the right portal vein was suggested. Portography showed divergence of the considerably preserved right caudate lobe branch (PV1R) from the root of the right portal vein. The liver function was reevaluated 18 days after PVE was suggested. During this time, the ICGR15 (21–28%) and ICGK rate (0.12–0.10) deteriorated. The right caudate lobe was significantly enlarged; thus, a total caudate lobe-preserving hepatectomy (TCPRx) was performed. Patients eligible for TCPRx included those with (1) hepatocellular carcinoma or metastatic liver cancer, (2) no tumor in the caudate lobe, (3) marginal liver function (ICG Krem greater than 0.05 if TCPRx was adapted; otherwise, less than 0.05) and Child–Pugh classification category A, and (4) preserved PV1R and right caudate bile duct branch. The procedure was performed through (A) precise estimation of the remnant liver volume preoperatively, (B) repeated intraoperative cholangiography to confirm the biliary branch of the right caudate lobe (B1R) conservation, and (C) stapler division of posterior and anterior Glisson’s pedicles laterally to avoid injuries to the PV1R and B1R. Conclusions Right hepatectomy with total caudate lobe preservation, following PVE, was a safe and viable surgical technique for patients with marginal liver function.

Purpose: To quantify liver metastases and future remnant liver (FRL) volumes in patients who underwent right portal vein embolization (RPVE) and to evaluate the effects of this procedure on metastase growth. Material and Methods: Nine patients with liver metastases from primary colon (n = 5), rectal lesions (n = 1) and carcinoid tumors (n = 3) underwent spiral CT to evaluate the ratio of the non-tumorous parenchymal volume of the resected liver to that of the whole liver volume (R2). Hand tracing was used to isolate the entire liver, the resected liver and metastase volumes. All patients with R2 > 60% underwent RPVE. Results: FRL exhibited a 101–336 cm3 (average 241 cm3) increase in volume 1 month after RPVE. One patient refused surgery for 2 months and before surgery the increase in volume of the FRL was similar to that of other patients (180.64 cm3). Percent metastases volume from colorectal carcinoma in embolized liver parenchyma increased from 62.4% to 138.4% at 1 month and to 562% at 2 months after RPVE. Metastase volume from carcinoid tumors was unchanged. Conclusion: One month after RPVE, hypertrophy of the FRL is evident. In the embolized liver, there was a progressive increase in metastase volume from colorectal carcinoma while metastase volume from carcinoid tumor was unchanged in embolized and non-embolized liver.

The small remnant liver volume remains an urgent problem in liver resection surgery. The use of the method of twostage liver resection – the Associated Liver Partition and Portal vein ligation for Staged hepatectomy in most cases allows to solve this problem. However, this method is associated with a number of complications and limitations. The presented clinical observation shows the effectiveness of an alternative version of this technology – radiofrequency ablation of the liver parenchyma in the plane of the proposed resection with ligation of the right branch of the portal vein to increase the volume of the estimated liver remnant in intrahepatic cholangiocellular cancer.

319 Background: Portal vein embolization (PVE) is a multi-potential treatment for hepatocellular carcinoma (HCC). The aim of this study is to identify the efficacies of PVE for resectable and unresectable HCC patients. Methods: Until 2011, 668 HCC patients underwent hepatic resection and 102 HCC patients treated with PVE. PVE was performed with percutaneous and ipsilateral approach using ethanolamine oleate iopamidol. Preoperative future remnant liver volume (%LV) and functional liver volume (%FLV ) were assessed with our developed combined 99mTc- galactosyl human serum albumin (GSA) scintigraphy (SPECT)/CT system. In unresectable cases chemoembolization (TACE) was repeated after PVE. Results: 1. Comparison of %LV and %FLV after right-PVE (n=40). %FLV before PVE was significantly lower in PVE group (38%) compared to non-PVE group (58%), but increased remarkably after PVE (from 38% to 55%, P < 0.0001). Right hepatectomy was successfully completed in 10 patients based on %FLV, instead of conventional %LV. 2. Long-term prognosis after right-hepatectomy with /without PVE (n=60). The 3- and 5-year disease-free survival (DFS) rates in the PVE group were significantly greater than those in the non-PVE group (78% and 78% versus 20% and 0%, P = 0.01). The 3- and 5-year overall survival (OS) rates in the PVE group were also higher than those in the non-PVE group (72% and 72% versus 57% and 12%, P <0.05). By multivariate analysis, independent prognostic factors for DFS were application of PVE (HR3.59), Multiple tumor (HR3.57), Fibrosis stage F3–4 (HR2.81), and protein induced by vitamin K absence or antagonists-II (PIVKA-II) ≥678AU/ml (HR2.69). 3. Prevention of intrahepatic metastases in unresectable HCCs in hemi-liver (n=40). The 3-year intrahepatic recurrence rates in the non-portal-embolized area was 58.8% and 81.8%, and the 5-year OS was 38.2% and 8.5%, in the PVE/TACE group and TACE group, respectively. The former rates were sinificantly higher (P<0.05). Conclusions: PVE can improve resectability, and might improve disease-free and overall survival for patients with both resectable and unresectable HCC.

Abstract Background The associating liver partitioning and portal vein occlusion for staged hepatectomy (ALPPS) procedure is gaining interest because it brings hope to patients who cannot undergo radical surgical resection due to insufficient remnant liver volume. However, the indications and technical aspects of this procedure are still under debate. This report demonstrates the technical aspects of the first two-stage robotic ALPPS for HCC. Case presentation A 55-year-old man with type II portal vein variation was diagnosed with hepatocellular carcinoma. Preoperative 3D reconstruction of the liver based on CT showed a future liver remnant/standard liver volume (FLR/SLV) of 24.45%. The ALPPS procedure was performed using the da Vinci Si system. At the first stage of the operation, we removed the gallbladder and ligated the right anterior branch of the portal vein and the right posterior branch. Following blocking of the hepatic hilum, the liver parenchyma was removed 1 cm away from the right side of the falciform ligament in an incision manner from the top to the bottom and from shallow to deep. The second-stage operation was performed on the 12th postoperative day with a FLR/SLV of 45.13%. During this step, the right hemiliver plus left medial section was separated and removed. Postoperative pathology showed a negative margin. The operative times were 195 and 217 min, respectively. Estimated blood loss was 250 and 500 ml, respectively. There was no need for transfusion or hospitalization in intensive care. The patient was discharged on the 6th postoperative day. Recovery was uneventful after both stages, and the patient did not present any sign of liver failure. Elevation of liver enzymes was minimal. The patient had no evidence of the disease 14 months after the procedure. Conclusions The two-stage robotic ALPPS procedure is a safe and feasible technique for select patients with HCC.

A 72-year-old woman with a sigmoid colon cancer anda synchronous colorectal liver metastasis (CRLM), whichinvolved the right hepatic vein (RHV) and the inferiorvena cava (IVC), was referred to our hospital. Themetastatic lesion was diagnosed as initially unresectablebecause of its invasion into the confluence of theRHV and IVC. After she had undergone laparoscopicsigmoidectomy for the original tumor, she consequentlyhad 3 courses of modified 5-fluorouracil, leucovorin,and oxaliplatin (mFOLFOX6) plus cetuximab. Computedtomography revealed a partial response, and theconfluence of the RHV and IVC got free from cancerinvasion. After 3 additional courses of mFOLFOX6 pluscetuximab, preoperative percutaneous transhepaticportal vein embolization (PTPE) was performed tosecure the future remnant liver volume. Finally, a righthemihepatectomy was performed. The postoperativecourse was uneventful. The patient was dischargedfrom the hospital on postoperative day 13. She hadneither local recurrence nor distant metastasis 18 moafter the last surgical intervention. This multidisciplinarystrategy, consisting of conversion chemotherapy usingFOLFOX plus cetuximab and PTPE, could contributein facilitating curative hepatic resection for initiallyunresectable CRLM.Key words: Initially unresectable; Colorectal liver metastasis;Conversion chemotherapy; Cetuximab; Percutaneoustranshepatic portal vein embolization

Staged Hepatectomy

Background In patients with bilobar metastatic liver disease, surgical clearance of both liver lobes may be achieved through multiple-stage liver resections. For patients with extensive disease, a major two-staged hepatectomy consisting of resection of liver segments II and III before right-sided portal vein embolization (PVE) and resection of segments V–VIII may be performed, leaving only segments IV ± I as the liver remnant. Purpose To describe the outcome following right-sided PVE after prior complete resection of liver segments II and III. Material and Methods In this retrospective study, 15 patients (mean age = 60.4 ± 9.3 years) with liver metastases from colorectal cancer (n = 14) and uveal melanoma (n = 1) who were scheduled to undergo a major two-stage hepatectomy, were included. Total liver volume (TLV) and volume of the future liver remnant (FLR) were measured on pre- and postinterventional computed tomography (CT) scans, and standardized FLR volumes (ratio FLR/TLV) were calculated. Patient data were retrospectively analyzed regarding peri- and postinterventional complications, with special emphasis on liver function tests. Results The mean standardized post-PVE FLR volume was 26.9% ± 6.4% and no patient developed hepatic insufficiency after the PVE. Based on FLR hypertrophy and liver function tests, all but one patient were considered eligible for the subsequent right-sided hepatectomy. However, due to local tumor progression, only 9/15 patients eventually proceeded to the second stage of surgery.   Conclusion Right-sided PVE was safe and efficacious in this cohort of patients who had previously undergone a complete resection of liver segments II and III as part of a major staged hepatectomy pathway leaving only segments IV(±I) as the FLR.

Abstract Background: Portal vein embolization (PVE) is a common procedure to induce hypertrophy of the remnant liver (RL) before major hepatectomy. Objective: Evaluate increased RL volume after PVE based on CT volumetric measurement. Methods: Multi-detector computed tomography (MDCT) was used to measure hepatic volumetric measurement, including total liver volume and RL volumes of pre- and post-PVE. Complications were recorded from PVE and from three-month after post-extended hepatectomy liver dysfunction. Result and conclusion: There was a 10% increase in RL volume. Mean days between CT and PVE were 20 days. No major complications from PVE were observed.
