Future liver remnant hypertrophy rate in portal vein embolization before left trisectionectomy: a retrospective cohort study. Abdom Radiol (NY) 2022; 47:878-884. [PMID: 34958405 DOI: 10.1007/s00261-021-03387-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 12/10/2021] [Accepted: 12/12/2021] [Indexed: 10/19/2022]
Abstract
PURPOSE Reports on the future liver remnant (FLR) hypertrophy rate in patients undergoing portal vein embolization (PVE) before left trisectionectomy are sparse. This study aimed to assess the FLR hypertrophy rate in patients undergoing PVE before left trisectionectomy. METHODS Between January 2010 and June 2021, 30 patients (22 men and eight women; mean age, 65.7 years) underwent PVE, mainly using gelatin sponge, before left trisectionectomy. The preoperative diagnosis was cholangiocarcinoma in 28 patients and colorectal liver metastases in two patients. The FLR hypertrophy rate, increase in the FLR volume (FLRV) ratio (the ratio of the FLRV to the total liver volume), and complications were evaluated. The patients were further divided into two groups: one group of patients with left portal vein stenosis or occlusion before PVE (n = 12) and another without left portal vein stenosis or occlusion before PVE (n = 18). The FLR hypertrophy rate and increase in the FLRV ratio were compared between the two groups. RESULTS The FLR hypertrophy rate and increase in the FLRV ratio were 31.3% and 6.9%, respectively. One major complication, cholangitis, developed; however, its association with PVE was unclear. The difference in the FLR hypertrophy rate and the increase in the FLRV ratio between the two groups of patients was statistically insignificant. CONCLUSION PVE before left trisectionectomy is effective in achieving FLR hypertrophy. PVE before left trisectionectomy was equally effective in patients with left portal vein stenosis or occlusion as compared to those without. The complication rates were acceptable.

Efficacy of Portal Vein Embolization with a Procedure of Sheath Injection and Balloon Occlusion with Gelatin Sponge. J Belg Soc Radiol 2021; 105:42. [PMID: 34568747 PMCID: PMC8428292 DOI: 10.5334/jbsr.2485] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Accepted: 08/10/2021] [Indexed: 11/20/2022] Open
Abstract
Introduction: To evaluate the efficacy, safety, and associated complications of a novel and simple approach to portal vein embolization that utilizes sheath injection and balloon occlusion (PVE-SIBO) with gelatin sponge (GS) for the purpose of increasing future liver remnant (FLR) volume. Methods: Between 1 January, 2006, and 31 August, 2020, 20 patients (15 men, 5 women, aged 64.6 ± 10.2 years) diagnosed with hepatobiliary malignancy underwent presurgical PVE-SIBO at our institution via a percutaneous transhepatic approach to the right portal vein and embolization of the portal vein with GS. We evaluated the increased ratio of FLR volume, operation duration, recanalization rate, and complications following this procedure. Results: All procedures were successful and without complications such as subcapsular hematoma, intra-abdominal bleeding, and bile leakage. The increased ratio of FLR volume was 34.7 ± 23.7% after a mean of 14.3 ± 2.57 days, and there was a significant difference in the FLR volume before and after PVE (P < 0.01). Procedure time was 52.7 ± 11.4 minutes. Conclusion: PVE-SIBO with GS is a simple, effective, and safe procedure to increase the ratio of FLR volume prior to hepatic surgeries.

Non-Ionic Surfactants for Stabilization of Polymeric Nanoparticles for Biomedical Uses. MATERIALS (BASEL, SWITZERLAND) 2021; 14:3197. [PMID: 34200640 PMCID: PMC8226872 DOI: 10.3390/ma14123197] [Citation(s) in RCA: 50] [Impact Index Per Article: 16.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Revised: 05/27/2021] [Accepted: 05/31/2021] [Indexed: 12/14/2022]
Abstract
Surfactants are essential in the manufacture of polymeric nanoparticles by emulsion formation methods and to preserve the stability of carriers in liquid media. The deposition of non-ionic surfactants at the interface allows a considerable reduction of the globule of the emulsion with high biocompatibility and the possibility of oscillating the final sizes in a wide nanometric range. Therefore, this review presents an analysis of the three principal non-ionic surfactants utilized in the manufacture of polymeric nanoparticles; polysorbates, poly(vinyl alcohol), and poloxamers. We included a section on general properties and uses and a comprehensive compilation of formulations with each principal non-ionic surfactant. Then, we highlight a section on the interaction of non-ionic surfactants with biological barriers to emphasize that the function of surfactants is not limited to stabilizing the dispersion of nanoparticles and has a broad impact on pharmacokinetics. Finally, the last section corresponds to a recommendation in the experimental approach for choosing a surfactant applying the systematic methodology of Quality by Design.

Abstract
Liver volume and function after hepatectomies are directly correlated to postoperative complications and mortality. Consequently contemporary liver surgery has focused on reaching an adequate future liver remnant so as to diminish postoperative morbidity and mortality. Portal vein embolization has evolved and is the standard of care as a liver regenerative strategy in many surgery departments worldwide before major liver resections. Different embolic materials have been used for portal vein embolization including gelfoam, ethanol, polyvinyl-alcohol particles, calibrated microspheres, central vascular plugs, coils, n-butyl-cyanoacrylate glue, fibrin glue, polidocanol-foam, alcoholic prolamin solution, and ethylene vinyl alcohol copolymer, as sole occluders or in varied combinations. While to date there has been no prospective controlled trial comparing the efficacy of different embolic materials in portal vein embolization, retrospective data insinuates that the use of n-butyl-cyanoacrylate and absolute ethanol produces higher contralateral liver hypertrophies. In this review, we evaluated publications up to August 2019 to assess the technical and regenerative results of portal vein embolization accomplished with different embolic materials. Special attention was given to specific aspects, advantages, and drawbacks of each embolic agent used for portal vein embolization, its liver regenerative performance, and its influence on patient outcome.

Abstract
Background Percutaneous transhepatic portal vein embolization (PTPE) can increase the future liver remnant (FLR) volume before extended liver resection; however, there is no current consensus regarding the best embolic material for PTPE. Purpose To evaluate the efficacy of PTPE using gelatin sponge particles and coils. Material and Methods The medical records of 136 patients who underwent PTPE using gelatin sponge particles and metal coils were retrospectively reviewed. We evaluated the procedural details, liver volume on CT, and clinical status before and after PTPE. Results The mean FLR volume increased significantly from 390 ± 147 cm3 to 508 ± 141 cm3 (P < 0.001). A mean of 22.1 ± 9.4 days after PTPE, the mean increase in the ratio of FLR volume to total liver volume was 9.4 ± 6.5%. Complications related to PTPE occurred in five patients, including arterial damage (n = 4) and biloma (n = 1). The white blood cell count and C-reactive protein level increased significantly and then returned to baseline within seven days. Aspartate aminotransferase and alanine aminotransferase showed no significant changes. Fever (defined by the Common Terminology Criteria for Adverse Events v4.0) was reported in 74 patients (54%), but it was generally mild (Grade 1/2; n = 72). None of the patients experienced severe complications that required cancellation of surgery. Conclusion PTPE with gelatin sponge particles and coils may impose low physical stress on patients and is a safe method of inducing a significant increase of FLR.

Abstract
Purpose To evaluate the efficacy of portal vein embolization (PVE) with n-Butyl-cyanoacrylate (NBCA) through an ipsilateral approach before major hepatectomy. Secondary end-points were PVE safety, liver resection and patient outcome. Methods Over a 5-year period 50 non-cirrhotic consecutive patients were included with primary or secondary liver cancer treatable by hepatectomy with a liver remnant (FLR) volume less than 25% or less than 40% in diseased livers. Results There were 37 men and 13 women with a mean age of 57 years. Colorectal liver metastases were the most frequent tumor and patients were previously exposed to chemotherapy. FLR increased from 422 ml to 629 ml (P < 0.001) after PVE, corresponding to anincrease of 52%. The FLR ratio increased from 29.6% to 42.3% (P < 0.001). Kinetic growth rate was 2.98%/week. A negative association was observed between increase in the FLR and FLR ratio and FLR volume before PVE (P = 0.002). In 31 patients hepatectomy was accomplished and only one patient presented with liver insufficiency within 30 days after surgery. Conclusions PVE with NBCA through an ipsilateral puncture is effective before major hepatectomy. Meticulous attention is needed especially near the end of the embolization procedure to avoid complications. Trial registration Clinical Study ISRCTN registration number: ISRCTN39855523.

Abstract
PURPOSE To report outcomes after portal vein embolization (PVE) and right hepatectomy in patients receiving embolization with N-butyl cyanoacrylate (NBCA) glue + central AMPLATZER Vascular Plug (AVP; glue group) or polyvinyl alcohol (PVA) particles ± coils (PVA group). MATERIALS AND METHODS Between March 2008 and August 2013, all patients having PVE with NBCA + AVP or PVA ± coils before right hepatectomy were retrospectively reviewed; 85 patients underwent PVE with NBCA + AVP (n = 45) or PVA ± coils (n = 40). The groups were compared using Mann-Whitney U and χ2 tests. RESULTS Technical success of embolization was 100%. Degree of hypertrophy (16.2% ± 7.8 vs 12.3% ± 7.62, P = .009) and kinetic growth rate (3.5%/wk ± 2.0 vs 2.6%/wk ± 1.9, P = .016) were greater in the glue group versus the PVA group. Contrast volume (66.1 mL ± 44.8 vs 189.87 mL ± 62.6, P < .001) and fluoroscopy time (11.2 min ± 7.8 vs 23.49 min ± 11.7, P < .001) were significantly less during the PVE procedure in the glue group. Surgical outcomes were comparable between groups, including the number of patients unable to go onto surgery (P = 1.0), surgical complications (P = .30), length of hospital stay (P = .68), and intensive care unit admissions (P = .71). There was 1 major complication (hepatic abscess) in each group after PVE. CONCLUSIONS PVE performed with NBCA + AVP compared with PVA ± coils resulted in greater degree of hypertrophy of the future liver remnant, less fluoroscopic time and contrast volume, and similar complication rates.

Abstract
BACKGROUND Previously, we reported on the clinical efficacy and safety of portal vein embolization (PVE) with fibrin glue. Our embolic materials for PVE changed from fibrin glue to absolute ethanol (EOH) after 2001 due to prohibition of using fibrin glue for PVE. With introducing our technique of PVE with EOH, we evaluated its safety and efficacy with attention to the amount of EOH. METHODS The medical records of 154 patients who underwent PVE using EOH were retrospectively reviewed. RESULTS Changes with time in both the serum levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) after PVE returned to the initial condition within 7 days after PVE. In the 96 patients who underwent CT volumerty 14 to 21 days after PVE, the volume of the embolized lobe decreased from 701 ± 165 cm(3) to 549 ± 148 cm(3) (P < 0.0001). Meanwhile, the volume of the non-embolized lobe increased from 388 ± 105 cm(3) to 481 ± 113 cm(3) (P < 0.0001). On simple linear regression, the amount of EOH was positively correlated with both the maximum of AST and that of ALT after PVE; however, it never correlated with changes in liver volume after PVE. CONCLUSIONS Portal vein embolization with EOH has a substantial effect on both hypertrophy of the non-embolized lobe and atrophy of the embolized lobe. Quick recoveries of changes with time in AST and ALT after PVE proved that PVE with EOH is a safe procedure. The amount of EOH affected the extent of liver damage but had no clinical effects on changes in liver volume after PVE.

Abstract
PURPOSE To retrospectively analyze efficacy as measured by volume gain of future remnant liver (FRL) after right portal vein embolization (PVE) using particles only versus particles and additional central plug and/or coil (CP/C) embolization. METHODS All patients who underwent PVE between July 2011 and December 2012 were retrospectively analyzed. Right PVE was performed either with particle-only (PO) embolization or additional CP/C embolization. All enrolled patients underwent computed tomography or magnetic resonance imaging before PVE and surgery. The images were used for volumetry of the FRL. RESULTS Of 75 patients, 40 had PO and 35 CP/C embolization. Age, sex, and tumor entities did not differ significantly between the two groups. Tumor entities included cholangiocarcinoma (n = 52), metastasis from colorectal cancer (n = 14), hepatocellular carcinoma (n = 2), and others (n = 7). Time from PVE to preoperative imaging was similar in both groups. FRL volume before PVE was 329 ± 121 ml in the PO group and 333 ± 135 ml in the CP/C group, and 419 ± 135 ml and 492 ± 165 ml before operation. The average percentage volume gain was significantly higher in the CP/C group than in the PO group, with 53.3 ± 34.5 % versus 30.9 ± 28.8 % (p = 0.002). CONCLUSION Right PVE with additional CP/C embolization leads to a significantly higher gain in FRL volume than embolization with particles alone.

Abstract
Metastatic liver disease is the most common cause of death in cancer patients. Complete surgical resection is currently considered the only curative treatment, with only about 25% of patients being amenable to surgery. Therefore, a variety of interventional oncologic techniques have been developed for treating secondary liver malignancies. The aim of these therapies is either to allow patients with unresectable tumors to become surgical candidates, provide curative treatment options in nonsurgical candidates, or improve survival in a palliative or even curative approach. Among these interventional therapies are transcatheter therapies such as portal vein embolization, hepatic artery infusion chemotherapy, transarterial chemoembolization, and radioembolization, as well as interstitial techniques, particularly radiofrequency ablation as the most commonly applied technique. The rationale, application and clinical results of each of these techniques are reviewed on the basis of the current literature. Future prospects such as gene therapy and immunotherapy are introduced.

Abstract
OBJECTIVE The purpose of this article is to evaluate the feasibility and efficacy of preoperative percutaneous transhepatic portal vein embolization with ethanol injection. MATERIALS AND METHODS We retrospectively evaluated 143 patients who underwent percutaneous transhepatic portal vein embolization. Hypertrophy of the future liver remnant was assessed by comparing the volumetric data obtained from CT image data before and after percutaneous transhepatic portal vein embolization. The evaluation of effectiveness was based on changes in the absolute volume of the future liver remnant and the ratio of the future liver remnant to the total estimated liver volume. RESULTS Ten of 143 patients (7.0%) underwent additional embolization because of recanalization and insufficient hypertrophy of the future liver remnant. The mean increase in the ratio of the future liver remnant was 33.6% (p < 0.0001), and the mean ratio of future liver remnant to total estimated liver volume increased from 34.9% to 45.7% (p < 0.0001). Although most of the patients complained of pain after ethanol injection, they were gradually relieved of pain in a few minutes by conservative treatment. Fever (38-39°C) was reported after 47 of 151 (31.1%) percutaneous transhepatic portal vein embolization sessions and was resolved within a few days. Transient elevation of the liver transaminases was observed after the procedures and resolved within about a week. Major complications occurred in nine of 151 (6%) percutaneous transhepatic portal vein embolization sessions, but no patients developed hepatic insufficiency or severe complications precluding successful resection. One hundred twenty patients underwent hepatic resection, and two patients developed hepatic failure after surgery. CONCLUSION Preoperative percutaneous transhepatic portal vein embolization with ethanol is a feasible and effective procedure to obtain hypertrophy of the future liver remnant for preventing hepatic failure after hepatectomy.

Abstract
Polyvinyl alcohol (PVA) is a synthetic polymer derived from polyvinyl acetate through partial or full hydroxylation. PVA is commonly used in medical devices due to its low protein adsorption characteristics, biocompatibility, high water solubility, and chemical resistance. Some of the most common medical uses of PVA are in soft contact lenses, eye drops, embolization particles, tissue adhesion barriers, and as artificial cartilage and meniscus. The purpose of this review is to evaluate the available published information on PVA with respect to its safety as a medical device implant material for cartilage replacement. The review includes historical clinical use of PVA in orthopedics, and in vitro and in vivo biocompatibility studies. Finally, the safety recommendation involving the further development of PVA cryogels for cartilage replacement is addressed.

Abstract
PURPOSE First, to evaluate hepatocyte phospholipid metabolism and energetics during liver regeneration stimulated by portal vein embolization (PVE) using proton-decoupled (31)P MR spectroscopic imaging ((31)P-MRSI). Second, to compare the biophysiologic differences between hepatic regeneration stimulated by PVE and by partial hepatectomy (PH). MATERIALS AND METHODS Subjects included six patients with hepatic metastases from colorectal cancer who were scheduled to undergo right PVE before definitive resection of right-sided tumor. (31)P-MRSI was performed on the left liver lobe before PVE and 48 h following PVE. Normalized quantities of phosphorus-containing hepatic metabolites were analyzed from both visits. In addition, MRSI data at 48 h following partial hepatectomy were compared with the data from the PVE patients. RESULTS At 48 h after PVE, the ratio of phosphomonoesters to phosphodiesters in the nonembolized lobe was significantly elevated. No significant changes were found in nucleoside triphosphates (NTP) and Pi values. The phosphomonoester (PME) to phosphodiester (PDE) ratio in regenerating liver 48 h after partial hepatectomy was significantly greater than PME/PDE 48 h after PVE. CONCLUSION (31)P-MRSI is a valid technique to noninvasively evaluate cell membrane metabolism following PVE. The different degree of biochemical change between partial hepatectomy and PVE indicates that hepatic growth following these two procedures does not follow the same course.

Abstract
BACKGROUND Two-stage liver resection (2-SLR) is used clinically in conjunction with portal vein embolization for bilobar disease to increase the number of patients suitable for liver resection. The long-term outcomes after 2-SLR for multiple bilobar colorectal liver metastases (CLM) was examined. METHODS Patients who sought care between November 2003 and April 2006 with multiple CLM considered suitable for 2-SLR were prospectively followed. Clinicopathological data were collected. Surgical outcomes were defined as complete clearance of tumor (R0/R1/R2), postoperative morbidity (within 3 months), 30 day mortality, disease-free survival (DFS), and overall survival (OS). RESULTS A total of 131 patients with CLM underwent liver resection during the study period, 38 of whom were planned for a 2-SLR for multiple bilobar disease. Only 33 (87%) completed the 2-SLR with a curative intent. Five patients did not undergo stage II resection because of disease progression. The postoperative morbidity was 11 and 33% after stage I and stage II liver resections, respectively. Five patients (13%) encountered postoperative complications specific to liver surgery. The median interval from stage II resection to disease recurrence in the R0 group was 18 months versus 3 months in the R1/R2 group (P < 0.001). R0 resection with curative intent versus R1/R2 noncurative resection has a significantly longer period of DFS (P < 0.001) and OS (P = 0.04). CONCLUSIONS The 2-SLR combined with portal vein embolization is an effective and safe method for resecting previously unresectable multiple bilobar CLM. However, a positive resection margin leads to poor DFS and OS.

Abstract
PURPOSE To evaluate the clinical safety and effectiveness of foam sclerotherapy using polidocanol for preoperative portal vein embolization (PVE) before hemihepatectomy of the liver. MATERIALS AND METHODS From March 2006 to October 2008, foam sclerotherapy using polidocanol was performed in 16 patients (male-to-female ratio of 12:4, age range 48-75 years [mean 62]) for PVE. Patients were diagnosed with Klatskin tumor (n = 13), gallbladder (GB) cancer (n = 2), or hepatocellular carcinoma (HCC) (n = 1). The foam was composed of a 1:2:1 ratio of 3% polidocanol (Aethoxysklerol; Kreussler Pharma, Wiesbaden, Germany), room air, and contrast media (Xenetix 350; Guerbet, Aulnay-Sous-Bois, France). The total amount of polidocanol used (2 to 8 mL [mean 4.6]) varied according to the volume of the target portal vein. We calculated the volume of future liver remnant (FLR) before and after PVE and evaluated complications associated with the use of polidocanol foam sclerotherapy for PVE. RESULTS Technical success was achieved in all patients. All patients were comfortable throughout the procedure and did not experience pain during sclerotherapy. No periprocedural morbidity or mortality occurred. Patients underwent a liver dynamic computed tomography (CT) scan 2-4 weeks after PVE. FLR increased significantly after PVE using polidocanol foam from 19.3% (range 16-35%) before PVE to 27.8% (range 23-42%) after PVE (p = 0.001). All patients were operable for hemihepatectomy of the liver and achieved effective resection. CONCLUSION Foam sclerotherapy using polidocanol is clinically safe and effective for preoperative PVE.

Abstract
BACKGROUND To analyze predictive factors of hypertrophy of the nonembolized future remnant liver (FRL) after transhepatic preoperative portal vein embolization (PVE) of the liver to be resected. MATERIALS AND METHODS Age, gender, indocyanin green clearance test, chemotherapy before PVE, type of chemotherapy, operators, extent of PVE, radiofrequency ablation (RFA) associated with PVE, time delay between PVE and surgery, and platelet count were retrospectively evaluated as predictive factors for hypertrophy of FRL in 107 patients with malignant disease in noncirrhotic liver. PVE targeted the right liver lobe [n = 70] or the right liver lobe and segment IV [n = 37] when FRL/total liver volume ratio was below 25% in healthy liver or 40% in altered liver. RESULTS After PVE, FRL volume significantly increased by 69%, from 344 +/- 156 cm(3) to 543 +/- 192 cm(3) (P < .0001). The degree of hypertrophy was negatively correlated with FRL volume (correlation coefficient = -0.55, P < .0001) and FRL/TFL ratio (correlation coefficient = -0.52, P < .0001) before PVE. Patients, who have undergone chemotherapy with platin agents prior to PVE, demonstrated lower hypertrophy (P = .048). CONCLUSION Hypertrophy after PVE is inversely correlated to initial FRL volume. Hypertrophy of the liver might be influenced by the systemic chemotherapeutic received before PVE.

Abstract
BACKGROUND Portal vein embolization (PVE) has been gaining increasing acceptance before major hepatectomy. This review presents the application, outcome, and recent developments of PVE. METHODS After a systematic search of "portal vein embolization" in PubMed, we reviewed and retrieved articles written in English related to PVE. There were no other criteria for exclusion of published information pertaining to this topic. RESULTS Hypertrophy of future liver remnants with PVE in patients with hepatobiliary malignancy results in fewer complications and shorter hospital stays after major hepatectomy, and add to the pool of candidates for surgical treatment. Some new techniques, such as sequential hepatic artery-portal vein embolization and PVE with stem cell administration, have showed a promising clinical future. CONCLUSIONS PVE has achieved significant improvement in the outcome of major hepatectomy, and has enlarged the candidate pool of liver resection as well. Future study is needed to identify the precise mechanism of liver regeneration after PVE.

Abstract
The purpose was to evaluate the safety and efficacy of preoperative portal vein embolization (PVE) using an Amplatzer vascular plug (AVP). Forty-one patients who underwent PVE using gelatin sponge particles and the AVP were enrolled. The right portal branches were embolized using gelatin sponges (1-8 mm(3)) through a 5-F catheter, and the AVP was deployed at the first- or second-order right portal vein. Technical success and complications, recanalization, and changes of total estimated liver volumes (TELV), future liver remnant (FLR), and FLR/TELV were evaluated. Follow-up CT performed 6-43 days (median, 16 days) after PVE was used to evaluate volume parameters. PVE was technically successful in 40 of 41 patients. Major complications occurred in two patients, with one each having extensive portal vein thrombosis and liver abscess. Partial recanalization of the occluded portal vein was seen in one patient. The mean FLR volume (653 +/- 174 ml vs. 532 +/- 154 ml, p < 0.001) and mean FLR/TELV ratio (43 +/- 8% vs 36 +/- 7%, p < 0.001) were significantly higher after than before PVE. PVE using the AVP seems to be a relatively safe and effective technique for inducing hypertrophy of the FLR with minimal risk of recanalization.

Abstract
BACKGROUND Preoperative portal vein embolization (PVE) is increasingly used as a preparation for major hepatectomy in patients with inadequate liver remnant volume or function. However, whether segment 4 (S4) portal veins should be embolized is controversial. The effect of S4 PVE on the volume gain of segments 2 and 3 (S2+3) was examined. METHODS Among 73 patients with uninjured liver who underwent right portal vein embolization (RPVE, n = 15) or RPVE extended to S4 portal veins (RPVE+4, n = 58), volume changes in S2+3 and S4 after embolization were compared. Clinical outcomes and PVE complications were assessed. RESULTS After a median of 27 days, the S2+3 volume increased significantly after both RPVE and RPVE+4, but the absolute increase was significantly higher for RPVE+4 (median, 106 mL vs 141 mL; P = .044), as was the hypertrophy rate (median, 26% vs 54%; P = .021). There was no significant difference between RPVE and RPVE+4 in the absolute S4 volume increase (52 mL for RPVE vs 55 mL for RPVE+4; P = .61) or the hypertrophy rate of S4 (30% for RPVE vs 26% for RPVE+4; P = .45). Complications of PVE occurred in 1 patient (7%) after RPVE and 6 (10%) after RPVE+4 (P > .99). No PVE complication precluded subsequent resection. Curative hepatectomy was performed in 13 patients (87%) after RPVE and 40 (69%) after RPVE+4 (P = .21). CONCLUSIONS RPVE+4 significantly improves S2+3 hypertrophy compared with RPVE alone. Extending RPVE to S4 does not increase PVE-associated complications.

Abstract
OBJECTIVES The objectives of this study are 1) to determine whether the future liver remnant will grow after portal vein embolization (PVE) in patients with colon cancer on concurrent chemotherapy and 2) to determine whether recovery after extended hepatectomy is improved after PVE. PURPOSE Neoadjuvant chemotherapy followed by hepatic resection is an increasingly used therapeutic strategy for curative treatment for colorectal metastases. However, such chemotherapy may result in steatosis, liver damage, and compromised liver regeneration and recovery. This study aims to determine whether PVE can be used during neoadjuvant therapy to enhance growth of future residual liver and to improve postoperative recovery. METHODS From September 1999 to September 2004, 100 patients with colorectal metastases to the liver were subjected to PVE as preparation for extended hepatic resection, 43 of whom were embolized during neoadjuvant chemotherapy. Liver growth was examined by computed tomography volumetric analysis. Clinical outcomes of the 71 patients subsequently resected were compared with 100 consecutive patients subjected to extended resection without PVE (controls). RESULTS After a median wait of 30 +/- 2 days after PVE, patients on neoadjuvant chemotherapy experienced a median contralateral (nonembolized) liver growth of 22% +/- 3% compared with 26% +/- 3% for those without chemotherapy (P = NS). The number of patients with <5% growth was also similar: 4 of 43 versus 6 of 57 (P = NS). Comparison of patients resected after PVE to a simultaneous cohort of 100 consecutive patients subjected to extended resection without prior PVE demonstrated a lower fresh frozen plasma requirement (P = 0.01), a lower peak bilirubin (P = 0.002), and a shorter length of stay (P = 0.03). Mortality was similar (0% vs. 2%). CONCLUSIONS Liver growth occurs after PVE even when cytotoxic chemotherapy is administered. No major complications occurred with PVE. Patients requiring major hepatic resection should be considered for PVE during neoadjuvant chemotherapy to improve subsequent recovery after resection.

Abstract
INTRODUCTION Preoperative portal vein embolization (PVE) is used clinically to prevent postoperative liver insufficiency. The current study examined the impact of portal vein embolization on liver resection. METHOD A comprehensive Medline search to identify all registered literature in the English language on portal vein embolization. Meta-analysis was performed to assess the result of PVE and its impact on major liver resection. RESULT A total of 75 publications met the search criteria but only 37 provided data sufficiently enough for analysis involving 1088 patients. The overall morbidity rate for PVE was 2.2% without mortality. Four weeks following PVE, 85% patients underwent the planned hepatectomy (n = 930). Twenty-three patients had transient liver failure following resection after PVE (2.5%) but 7 patients developed acute liver failure and died (0.8%). The reason for nonresection following PVE (n = 158, 15%) included inadequate hypertrophy of remnant liver (n = 18), severe progression of liver metastasis (n = 43), extrahepatic spread (n = 35), refusal to surgery (n = 1), poor general condition (n = 1), altered treatment to transcatheter artery embolization or chemotherapy (n = 24), complete remission after treatment with 3 cycles of fluoracil and interferon alpha in a patient with hepatocellular carcinoma (n = 1), incomplete pre- or postembolization scanning (n = 8). Of those who underwent laparotomy without resection, (n = 27) reasons included intraoperative finding of peritoneal dissemination (n = 15), portal node metastasis (n = 2), severe invasion of the tumor to the hepatic artery and portal vein (n = 1), and gross tumoral extension precluding curative resection (n = 9). Two techniques were used for portal vein embolization: percutaneous transhepatic portal embolization, (PTPE) and transileocolic portal embolization, (TIPE). The increase in remnant liver volume was much greater in PTPE than TIPE group (11.9% vs. 9.7%; P = 0.00001). However, the proportion of patients who underwent resection following PVE was 97% in TIPE and 88% PTPE, respectively (P = <0.00001). Although there was no significant difference in patients who had major complications post-PVE, the rate for minor complications was significantly higher among patients who had PTPE (53.6% vs. 0%, P = <0.0001). CONCLUSION PVE is a safe and effective procedure in inducing liver hypertrophy to prevent postresection liver failure due to insufficient liver remnant.

Abstract
The liver is the most common site of metastatic disease from both gastrointestinal and extra-intestinal malignancies. Historically, only a minority of patients with colorectal liver metastases were candidates for resection. However, over the past several decades, liver resection has evolved as a safe and potentially curative treatment for hepatic colorectal metastases. The development of active chemotherapy and molecular targeted therapies, together with newer modalities like radiofrequency ablation, have expanded the indications for hepatic resection and improved survival. Selected patients with isolated liver metastases from neuroendocrine tumors, germ cell cancers, ocular melanoma, gastrointestinal stromal tumors (GIST), and breast cancer also may be considered for hepatic surgery.

Abstract
INTRODUCTION Few potentially curative treatment options exist besides resection for patients with very large (>or=10 cm) hepatocellular carcinoma (HCC). We sought to examine the outcomes and risk factors for recurrence after resection of >or=10 cm HCC. METHODS Perioperative and long-term outcomes were examined for 189 consecutive patients from 1993 to 2004 who underwent potentially curative resection of HCC >or=10 cm (n = 24; 13%) vs. those with HCC <10 cm (n = 165; 87%). Disease-free survival (DFS) and overall survival (OS) were determined by Kaplan-Meier analysis and patient, tumor, and treatment characteristics were compared using univariate and multivariate analysis. RESULTS Median follow-up was 34 months. Tumors >or=10 cm were more likely to be symptomatic, of poorer grade, and have vascular invasion (p < 0.05). Twelve patients (50%) underwent an extended resection of more than four hepatic segments or resection of adjacent organs for oncologic clearance (diaphragm-2, inferior vena cava (IVC)-2, median sternotomy-1). Postoperative complications were more common after resection of >10 cm HCC (12/24, 50% vs. 35/165, 21%; p = 0.04). Median DFS was significantly shorter in patients with large HCC (>or=10 cm) group compared to patients with smaller HCC (8.4 vs. 38 months; p = 0.001), but overall survival was not different between the two groups (5-year survival 54% vs. 53%; p = 0.43). Seventeen patients (71%) with very large HCC developed recurrences (12 intrahepatic, five systemic); eight of these patients (47%) underwent additional therapy (resection-4, TACE-3, RFA-1). Pathological positive margins and vascular invasion were significant determinants of DFS in tumors >or=10 cm (p < 0.05), but only vascular invasion was an independent risk factor for recurrence after multivariate analysis (HR 0.17; 95% CI: 0.04-0.8). Median OS after recurrence was 24 months. CONCLUSION Surgical resection is the optimal therapy for very large (>or=10 cm) HCC. Although recurrences are common after resection of these tumors, overall survival was not significantly different from patients after resection of smaller HCC in this series.
