Background
Portal vein embolization (PVE) reduces the risks of hepatic insufficiency after major hepatectomy for small predicted liver remnant. The extent of liver hypertrophy after PVE depends on various clinical factors. We sought to develop a nomogram for predicting the increase in the volume of segments 2 and 3 after right PVE (RPVE).Method
In 360 patients who underwent RPVE from 1998 through 2013, clinicopathologic data were analyzed, including body mass index (BMI), diabetes, aspirin use, viral hepatitis status, preoperative albumin level, total bilirubin level, prothrombin time, platelet count, type of liver neoplasm, preoperative chemotherapy, previous laparotomy or hepatectomy, segment 4 embolization, two-stage hepatectomy, and liver volumes before and after PVE. Multivariate linear regression analysis was used to identify variables predicting the degree of hypertrophy of segments 2 and 3.Results
Multivariate regression analysis revealed that BMI (p?=?0.002), previous hepatectomy (p?=?0.03), RPVE in the setting of two-stage hepatectomy (p?<?0.001), and segment 4 embolization (p?=?0.003) independently predicted the degree of hypertrophy of segments 2 and 3. Based on the fitted model, a nomogram was constructed.Conclusion
The constructed nomogram predicts the degree of hypertrophy of segments 2 and 3 after RPVE and can be used in clinical decision making for patients undergoing right hepatectomy.2.

Purpose
Several factors have been reported to affect liver regeneration after portal vein embolization (PVE); however, the effect of sinusoidal obstruction syndrome (SOS) has not been evaluated. Therefore, we assessed the effect of SOS on liver regeneration after PVE in patients with multiple bilobar colorectal liver metastases scheduled to undergo two-stage hepatectomy (TSH) combined with PVE.Methods
The subjects of this study were 78 patients prospectively scheduled to undergo TSH between December 1996 and August 2009. Archived formalin-fixed, paraffin-embedded nontumoral tissue samples were collected from the 1st- and 2nd-stage hepatectomies in 42 and 45 patients, respectively, and SOS and steatohepatitis were diagnosed pathologically. We analyzed the clinicopathological variables affecting liver regeneration after PVE.Results
Sinusoidal obstruction syndrome was diagnosed in 11 (26.2%) and 20 patients (44.4%) at the time of the 1st- and 2nd-stage hepatectomy, respectively. Patients with SOS at the 1st-stage hepatectomy had a significantly lower hypertrophy ratio of the future remnant liver (FRL) after PVE than patients without SOS (16.8 ± 24.0 vs 55.6 ± 32.5; P < 0.001). Multivariate logistic regression analysis revealed that SOS was an independent factor predicting lower FRL hypertrophy after PVE (??% FRL <20: hazard ratio 31.7, 95% confidence interval 2.84?C355.12; P = 0.005). The incidence of postoperative transient liver failure after the 2nd-stage hepatectomy in patients presenting with SOS was higher than that in those without SOS, but the difference did not reach significance (25.0% vs 4.0%; P = 0.052). Steatohepatitis was confirmed at the 1st- and 2nd-stage hepatectomy in 6 (14.3%) and 3 (6.7%) patients, respectively.Conclusion
Sinusoidal obstruction syndrome inhibits FRL hypertrophy after PVE and induces postoperative liver failure. Therefore, an alternative strategy is needed to perform TSH safely in the presence of SOS. 相似文献3.

Background and Aim
The clinical usefulness of portal vein embolization (PVE) for Klatskin tumor is not well established. The authors explored the change in liver volume and function before and after major hepatectomy and evaluated the effect of PVE.Methods
Thirty-three consecutive patients who underwent right hepatectomy with an initial future liver remnant (FLR)?≤?30 % for Klatskin tumors at Seoul National University Hospital were included.Results
Eleven patients underwent PVE, and eight patients received right trisectionectomy. PVE induced a mean FLR increase of 19.3 % after a mean of 15.8 days. At postoperative month 1, liver volume and liver hypertrophy ratio was comparable between PVE and no-PVE group. For patients with an initial FLR?≤?20 %, postoperative liver hypertrophy rate of PVE group was comparable to no-PVE group. Liver function tests were not affected by PVE or the initial FLR. Postoperative liver hypertrophy ratio was negatively correlated with the initial FLR (hypertrophy ratio (%)?=?326.7–0.4×initial FLR (ml), P?=?0.001). There was no severe PVE-related morbidity, and postoperative morbidity rate was comparable in PVE and no-PVE group.Conclusion
The postoperative liver hypertrophy ratio, final liver volume, or liver function tests were not affected by PVE. Postoperative liver hypertrophy was related to the initial FLR. 相似文献4.

Background
Although portal vein embolization (PVE) has been applied for surgical resection of colorectal liver metastases (CLM), the clinical usefulness of liver surgery following PVE for CLM remains unknown.Methods
A total of 115 patients were evaluated retrospectively. Among them, 49 underwent one-stage hepatectomy following PVE (PVE group). The remaining 66 patients underwent at least hemihepatectomy without PVE (non-PVE group). This analysis compared the short- and long-term outcomes between the PVE and non-PVE groups.Results
There were no deaths in either group. Using the Clavien–Dindo classification, the rates of postoperative morbidity ≥ grade 1 were 34.7 % in the PVE group and 25.0 % in the non-PVE group (p = 0.26). The 3-year overall survival rates were 54.6 and 64.5 % in the PVE and non-PVE groups, respectively (p = 0.89). The multivariate analysis the variable performance/nonperformance of PVE was not detected as an independent predictor of poor survival.Conclusions
Our one-stage hepatectomy policy of using PVE provides acceptable morbidity and favorable long-term outcomes. 相似文献5.

Background
When hepatectomy is used as a primary treatment for liver metastasis from colorectal cancer (CRCLM), the balance between surgical curability and functional preservation of the remnant liver is of great importance.Methods
A total of 108 patients who underwent initial hepatectomy for CRCLM were retrospectively analyzed with respect to tumor extent, operative method, and prognosis, including recurrence.Results
The 1-, 2-, 3-, and 5-year overall survival rates (OS) for all patients were 90.5%, 77.8%, 63.2%, and 51.6%, respectively. Multivariate analysis indicated serum carbohydrate antigen 19-9 (CA 19-9) level after hepatectomy (<36 or ??36?mAU/mL) and presence of recurrence as independent prognostic factors of OS (P?=?0.0458 and 0.0249, respectively), and tumor depth of colorectal cancer (Conclusions
In CRCLM, we believe that nonanatomic hepatectomy with narrow margin is indicated, and optimal treatment would include functional preservation of as much of the remnant liver as possible. 相似文献6.

Background
Portal vein occlusion to increase the size of the future liver remnant (FLR) is well established, using portal vein ligation (PVL) or embolization (PVE) followed by resection 4–8 weeks later. Associating liver partition with portal vein ligation for staged hepatectomy (ALPPS) combines PVL and complete parenchymal transection, followed by hepatectomy within 1–2 weeks. ALPPS has been recently introduced but remains controversial. We compare the ability of ALPPS versus PVE or PVL for complete tumor resection.Methods
A retrospective review of all patients undergoing ALPPS or conventional staged hepatectomies using PVL or PVE at four high-volume HPB centres between 2003 and 2012 was performed. Patients with primary liver tumors and liver metastases were included. Primary endpoint was complete tumor resection. Secondary endpoints include 90-day mortality, complications, FLR increase, time to resection, and tumor recurrence.Results
Forty-eight patients with ALPPS were compared with 83 patients with conventional-staged hepatectomies. Eighty-three percent (40/48 patients) of ALPPS patients achieved complete resection compared with 66 % (55/83 patients) in PVE/PVL (odds ratio 3.34, p = 0.027). Ninety-day mortality in ALPPS and PVE/PVL was 15 and 6 %, respectively (p = 0.2). Extrapolated growth rate was 11 times higher in ALPPS (34.8 cc/day; interquartile range (IQR) 26–49) compared with PVE/PVL (3 cc/day; IQR2-6; p = 0.001). Tumor recurrence at 1 year was 54 versus 52 % for ALPPS and PVE/PVL, respectively (p = 0.7).Conclusions
This study provides evidence that ALPPS offers a better chance of complete resection in patients with primarily unresectable liver tumors at the cost of a high mortality. The technique is promising but should currently not be used outside of studies and registries. 相似文献7.

Background
Tumor downsizing by effective chemotherapy while increasing remnant liver volume by two-stage hepatectomy can expand eligibility for resection of otherwise unresectable liver metastases. However, optimal timing of two-stage hepatectomy with respect to chemotherapy is undetermined.Methods
We retrospectively analyzed the effect of timing of two-stage hepatectomy and chemotherapy using data from 95 patients whose colorectal liver metastases initially were considered unresectable.Results
In 21 of 22 (95?%) patients whose first liver resection preceded chemotherapy (Hx-CTx group) and in 39 of 73 (53?%) patients whose chemotherapy preceded surgery (CTx-Hx group), macroscopic complete resection ultimately was achieved (P?0.01). Overall and disease-free survivals were comparable between groups. However, overall survival of patients not achieving complete resection in the CTx-Hx group was significantly poorer than that for patients achieving complete resection (P?0.01). When the 21 patients with complete resection in the Hx-CTx group were compared to the 39 patients with complete resection in the CTx-Hx group, no difference in overall or disease-free survival was observed (P?=?0.12 and P?=?0.24, respectively), although poor response to chemotherapy was more frequent in the Hx-CTx group.Conclusions
Optimal timing of hepatectomy and chemotherapy is difficult to specify, but performing the initial resection in a two-stage hepatectomy before chemotherapy may increase likelihood of macroscopic complete resection, even in patients with a poor response to chemotherapy or with limited courses of chemotherapy. 相似文献8.

Background
The aim was to analyze hepatic hypertrophy after portal vein embolization (PVE) and Associating Liver Partition with Portal vein ligation for Staged hepatectomy (ALPPS) to determine whether clinical circumstances associated with major hepatic resections correlated with remnant growth.Methods
Data was abstracted from a retrospectively maintained database on 27 patients undergoing hepatic resection followed by PVE and the ALPPS procedure between October 1, 2007 and December 31, 2016. The increasing rate of liver volume and remnant liver LU15 was defined as the percentage-point difference between the liver volume and remnant liver LU15 before and after the intervention or surgery. And correlation between kinetic growth rate (KGR) of liver and future remnant liver volume or remnant liver LU15 was analyzed.Results
The degree of hypertrophy (DH) of volume and LU15 was significantly greater after ALPPS (volume: 40.3% and LU15: 65.0%) than after PVE (volume: 22.7% and LU15: 48.8%) (P <?0.05). KGR of volume and LU15 was significantly greater after ALPPS (volume: 19.0 cm3/day and 2.00%/day) (LU15: 0.61 /day and 1.82%/day) than after PVE (volume: 3.89 cm3/day and 0.42%/day) (LU15: 0.19 /day and 0.63%/day) (P <?0.001). An inverse correlation between KGR and initial remnant liver volume was observed. And a positive correlation between KGR and LU15 was observed.Conclusion
Future remnant liver volume and KGR was greater after the ALPPS procedure than after PVE. Liver hypertrophy is related to the expected remnant liver volume and total liver function. This study suggested that total liver function and initial remnant liver volume might be a new indication of hepatectomy after PVE and ALPPS in the case of insufficient remnant liver volume.9.
Background
Liver regeneration that occurs after portal vein embolization (PVE) may have adverse effects on the microscopic tumor foci in the residual liver mass in patients with hepatocellular carcinoma (HCC).Methods
Fifty-four HCC patients with inadequate functional residual liver volume were offered PVE during a seven-year period. Among them, 34 (63%) patients underwent curative resection. They were compared with a matched control group (n?=?102) who underwent surgery without PVE. Postoperative complications, pattern of recurrence, and survival were compared between groups.Results
In the PVE group, a pre-embolization functional residual liver volume of 23% (12–33.5%) improved to 34% (20–54%) (p?=?0.005) at the time of surgery. When the two groups were compared, minor (PVE, 24%; control, 29%; p?=?0.651) and major (PVE, 18%; control, 15%; p?=?0.784) complications were similar. After a follow-up period of 35?months (standard deviation 25?months), extrahepatic recurrences were detected in 10 PVE patients (29%) and 41 control patients (40%) (p?=?0.310). Intrahepatic recurrences were seen in 10 (29%) and 47 (46%) cases (p?=?0.109) in the PVE and control groups, respectively. In the PVE group, 41% (n?=?14) of the recurrences were detected before one year, compared with 42% (n?=?43) in the control group (p?=?1). Disease-free survival rates at 1, 3, and 5?years were 57, 29, and 26% in the control group and 60, 42, and 42% in the PVE group (log-rank, p?=?0.335). On multivariate analysis, PVE was not a factor affecting survival (p?=?0.821).Conclusions
Portal vein embolization increases the resectability of initially unresectable HCC due to inadequate functional residual liver volume, and it has no deleterious oncological effect after major resection of HCC. 相似文献10.

Background
Preoperative portal vein embolization (PVE) is used to increase the future remnant liver (FRL) in patients requiring extensive liver resection. Computed tomography (CT) volumetry, performed not earlier than 3–6 weeks after PVE, is commonly employed to assess hypertrophy of the FRL following PVE. Early parameters to predict effective hypertrophy are therefore desirable. The aim of the present study was to assess plasma bile salt levels, triglycerides (TG), and apoA-V in the prediction of the hypertrophy response during liver regeneration.Methods
Serum bile salt, TG, and apoA-V levels were determined in 20 patients with colorectal metastases before PVE, and 5 h, 1, and 21 days after PVE, as well as prior to and after (day 1–7, and day 21) subsequent liver resection. These parameters were correlated with liver volume as measured by CT volumetry (%FRL-V), and liver function was determined by technetium-labeled mebrofenin hepatobiliary scintigraphy using single photon emission computed tomography.Results
Triglyceride levels at baseline correlate with volume increase of the future remnant liver (FRL-V) post-PVE. Also, bile salts and TG 5 h after PVE positively correlated with the increase in FRL volume (r = 0.672, p = 0.024; r = 0.620, p = 0.042, resp.) and liver function after 3 weeks (for bile salts r = 0.640, p = 0.046). Following liver surgery, TG levels at 5 h and 1 day after resection were associated with liver remnant volume after 3 months (r = 0.921, p = 0.026 and r = 0.981, p = 0.019, resp). Plasma apoA-V was increased during liver regeneration.Conclusions
Bile salt and TG levels at 5 h after PVE/resection are significant early predictors of liver volume and functional increase. It is suggested that these parameters can be used for early timing of volume assessment and resection after PVE. 相似文献11.

Introduction
The impact of phosphorus as well as glycemic alterations on liver regeneration has not been directly examined. We sought to determine the impact of phosphorus and glucose on liver regeneration after major hepatectomy.Methods
Early and late liver regeneration index was defined as the relative increase of liver volume (RLV) within 2[(RLV2m-RLVp)/RLVp] and 7 months[(RLV7m-RLVp)/RLVp] following surgery. The association of perioperative metabolic factors, liver regeneration, and outcomes was assessed.Results
On postoperative day 2, 50 (52.6 %) patients had a low phosphorus level (≤2.4 mg/dl), while 45 (47.4 %) had a normal/high phosphorus level (>2.4 mg/dl). Despite comparable clinicopathologic characteristics (all P?>?0.05) and RLV/TLV at surgery (P?=?0.84), regeneration index within 2 months was lower in the normal/high phosphorus group (P?=?0.01) with these patients having increased risk for postoperative liver failure (P?=?0.01). The inhibition of liver regeneration persisted at 7 months (P?=?0.007) and was associated with a worse survival (P?=?0.02). Preoperative hypoglycemia was associated only with a lower early regeneration index (P?=?0.02).Conclusions
Normal/high phosphorus was associated with inhibition of early and late liver regeneration, as well as with an increased risk of liver failure and worse long-term outcomes. Immediate preoperative hypoglycemia was associated with a lower early volumetric gain. Metabolic factors may represent early indicators of liver failure that could identify patients at increased risk for worse outcomes.12.

Background
An increasing number of patients undergo major liver resection following preoperative chemotherapy. Liver regeneration may be impaired in these patients, predisposing them to postoperative liver dysfunction. The aim of the present study was to evaluate the effects of preoperative chemotherapy on liver regeneration after partial liver resection.Methods
Patients planned to receive right hepatectomy either with (group B) or without (group A) prior chemotherapy were identified retrospectively from a prospective multi-institutional database created in the conduct of a national randomized controlled trial (RCT). Prior chemotherapy was neither an inclusion nor an exclusion criterion of the trial. Future remnant liver volume (FRLV) was calculated by measuring total functional liver volume and resection specimen on preoperative computed tomography (CT) scans. Remnant liver volume after 7 days (V RLV7days) was measured on scheduled postoperative CT scans. The early regeneration index 7 days after surgery (RI early) was calculated as [(V RLV7days ? FRLV) / FRLV] × 100 %. Data are expressed as median (interquartile range).Results
A total of 72 patients were enrolled: 45 in group A and 27 in group B. For the whole group, the liver remnant showed a 58 % (39 %) increase in volume at day 7 (1) day. The RI early was not significantly different between groups A and B, 60 % (36 %) and 50 % (43 %), respectively (p = 0.47). The RI early was significantly lower in patients who had undergone more than six cycles of chemotherapy.Conclusions
Preoperative chemotherapy does not seem to have a negative impact on early liver regeneration after partial liver resection. 相似文献13.

Background
Early recurrence correlates with poor survival following various cancer surgeries and puts considerable stress on patients both physically and mentally. This retrospective study investigated the predictive factors for early recurrence after surgical resection for initially unresectable colorectal liver metastasis to elucidate indications for conversion strategies.Methods
We retrospectively studied 46 patients who underwent hepatectomy after chemotherapy for initially unresectable colorectal liver metastasis from 1997 to 2010.Results
Recurrences occurred within 6 months after hepatectomy in 13 patients (37 %). The median survival time of 21.2 months and the 5-year survival rate of 0 % after hepatectomy in patients with recurrence within 6 months were significantly worse than those in patients with recurrence more than 6 months after hepatectomy. Recurrence in less than 6 months was significantly correlated with impossibility of anticancer therapy for recurrence after hepatectomy (p?=?0.01). Eight or more hepatic tumors after chemotherapy were the only predictor of recurrence within 6 months (p?=?0.01; odds ratio 9.6; 95 % confidence interval 1.5–60.6).Conclusion
Recurrence within 6 months was significantly correlated with a poorer outcome following surgery for initially unresectable colorectal liver metastasis. Surgical indication for initially unresectable colorectal liver metastasis with eight or more hepatic tumors after chemotherapy should be considered carefully in the light of mental and physical status, co-morbidity, and alternative treatment plans. 相似文献14.

Introduction
Portal vein embolization (PVE) stimulates hypertrophy of the future liver remnant (FLR) and may improve the safety of extended hepatectomy. The efficacy of PVE was evaluated.Methods
Records of 358 consecutive patients who underwent PVE before intended major hepatectomy at our institution from 1995 through 2012 were retrospectively reviewed.Results
One hundred twelve patients (31.3 %) had right PVE alone; 235 (65.6 %) had right PVE plus segment IV embolization. The first-session PVE completion rate was 97.8 %. The PVE complication rate was 3.9 %. The median pre-PVE and post-PVE standardized FLRs were 19.5 % (interquartile range, 15.0–25.9) and 29.7 % (interquartile range, 22.5–38.2), respectively. Two hundred forty patients (67.0 %) underwent potentially curative resection. Sixty-two patients (25.8 %) had major post-hepatectomy complications; rates of postoperative hepatic insufficiency and 90-day liver-related mortality were 8.3 and 3.8 %, respectively. The proportion of patients with colorectal liver metastasis increased from 38.6 % before 2005 to 78.2 % in 2010–2012. Despite increased use of preoperative chemotherapy, postoperative hepatic insufficiency and 90-day liver-related mortality rates dropped from 10.6 and 4.1 %, respectively, before 2010 to 2.9 and 2.9 %, respectively, in 2010–2012.Conclusions
PVE can be safely performed with minimal morbidity. Most patients can proceed to extended hepatectomy, which is associated with a minimal mortality rate. 相似文献15.
Purpose
To evaluate the safety and efficacy of sequential transcatheter arterial chemoembolization (TACE) and portal vein embolization (PVE) prior to surgery in hepatocellular carcinoma (HCC) patients and to compare the clinical outcome of the combined procedure with that of a matched group of patients undergoing PVE alone.Patients and Methods
From 1997 to 2008, 135 patients with HCC underwent sequential TACE and PVE (n = 71) or PVE alone (n = 64) before right hepatectomy. PVE was performed mean 1.2 months after TACE. In both groups, computed tomography (CT) and liver volumetry were performed before and 2 weeks after PVE to assess degree of left lobe hypertrophy.Results
Baseline patient and tumor characteristics were similar in the two groups. After PVE, the chronological changes of liver enzymes were similar in the two groups. The mean increase in percentage future liver remnant (FLR) volume was higher in the TACE + PVE group (7.3%) than in the PVE-only group (5.8%) (P = 0.035). After surgery, incidence of hepatic failure was higher in the PVE-only group (12%) than in the TACE + PVE (4%) group (P = 0.185). Overall (P = 0.028) and recurrence-free (P = 0.001) survival rates were significantly higher in the TACE + PVE group than in the PVE-only group.Conclusion
Sequential TACE and PVE before surgery is a safe and effective method to increase the rate of hypertrophy of the FLR and leads to longer overall and recurrence-free survival in patients with HCC. 相似文献16.

Purpose
To compare tumor progression in both embolized and non-embolized liver lobes after portal vein embolization (PVE) in patients with bilobar colorectal liver metastases (CLM), according to the initial response to induction chemotherapy.Methods
From 2002 to 2012, a total of 42 consecutive patients with bilobar CLM initially treated using induction chemotherapy underwent right PVE to achieve adequate future liver remnant volume. Tumoral and liver parenchyma volumes, as well as their volume variations, were measured on computed tomography before and after PVE in both embolized and non-embolized. Patients were classified as fast (≤6 cycles of induction chemotherapy) and slow (>6 cycles) responders.Results
Overall, 432 metastases were analyzed in 42 patients. Patients were slow responders in 29 (69 %) cases. Tumoral volume increased in 29 (69 %) cases in the embolized liver (+48 %; p < 0.0001), and in 28 (66 %) cases in the non-embolized liver (+31 %; p < 0.0001). Fast responders had a tumoral volume decrease in both embolized (?4 %) and non-embolized (?9 %) lobes. On the opposite side, slow responders had tumoral volume increase in both embolized (+79 %) and non-embolized (+32 %) lobes. On multivariate analysis, a ‘slow’ response to induction chemotherapy was the only factor associated with tumoral progression in both embolized (p = 0.0012) and non-embolized (p = 0.001) lobes.Conclusion
Tumor growth after PVE is observed in both embolized and non-embolized liver lobes in most patients but is significantly associated with slow response to induction chemotherapy. 相似文献17.

Background
Posthepatectomy liver failure (PHLF) is a major complication after hepatectomy. As there was no standardized definition, the International Study Group of Liver Surgery (ISGLS) defined PHLF as increased international normalized ratio and hyperbilirubinemia on or after postoperative day 5 in 2010. We evaluated the impact of the ISGLS definition of PHLF on hepatocellular carcinoma (HCC) patients.Methods
We retrospectively analyzed 210 consecutive HCC patients who underwent curative hepatectomy at our facility from 2005 to 2010. The median follow-up period after hepatectomy was 35.2 months.Results
Thirty-nine (18.6 %) patients fulfilled the ISGLS definition of PHLF. Overall survival (OS) rates at 1, 3, and 5 years in patients with/without PHLF were 69.1/93.5, 45.1/72.5, and 45.1/57.8 %, respectively (P?=?0.002). Recurrence-free survival (RFS) rates at 1, 3, and 5 years in patients with/without PHLF were 40.9/65.9, 15.7/38.3, and 15.7/20.3 %, respectively (P?=?0.003). Multivariate analysis revealed that PHLF was significantly associated with both OS (P?=?0.047) and RFS (P?=?0.019). Extent of resection (P?<?0.001), intraoperative blood loss (P?=?0.002), and fibrosis stage (P?=?0.040) were identified as independent risk factors for developing PHLF.Conclusion
The ISGLS definition of PHLF was associated with OS and RFS in HCC patients, and long-term survival will be improved by reducing the incidence of PHLF. 相似文献18.

Background
Liver stiffness is associated with the degree of fibrosis along with other factors. Abrupt change of liver perfusion after hepatectomy is one such factor. In this study, we performed ultrasound elastography to explore the stiffness of the right lobe liver before and after hepatectomy in donors who underwent resection of left lobe or lateral segment of liver.Methods
A total of 32 left lobe liver donors (18 male and 14 female; age range, 21–55 years; mean age, 35.1 years; 19 left lobectomy with middle hepatic reserved for graft and 13 lateral segmentectomy with middle hepatic vein reserved in the remnant liver) were included in this study. Liver stiffness was measured by means of ultrasound elastography with the use of acoustic radiation force impulse imaging. Stiffness of the right lobe liver was obtained by means of right intercostal approach.Results
The stiffness of remnant right lobe liver significantly increased after hepatectomy (1.24 ± 0.18 vs 1.10 ± 0.13 m/s; P = .001). Donors of left lobe liver showed higher stiffness in the remnant right lobe liver compared with donors of lateral segment (1.30 ± 0.18 vs 1.15 ± 0.14 m/s; P = .027). There was no significant correlation between the remnant right lobe liver stiffness, postoperative liver function, and flow parameters of hepatic artery and portal vein.Conclusions
The stiffness of remnant liver significantly increased after hepatectomy. Furthermore, the stiffness was higher in donors undergoing left lobectomy compared with those undergoing lateral segmentectomy. 相似文献19.

Aims
The aim of this study was to evaluate the ability of contrast-enhanced intraoperative ultrasonography to detect colorectal liver metastases after preoperative chemotherapy compared with intraoperative ultrasound and preoperative imaging techniques.Methods
From January 2010 to December 2011, 28 patients with colorectal liver metastases underwent intraoperative ultrasonography and contrast-enhanced intraoperative ultrasonography during hepatectomy following preoperative chemotherapy. The findings were compared to preoperative imaging using contrast-enhanced ultrasonography, computed tomography, magnetic resonance imaging, and/or fluorodeoxyglucose positron emission tomography.Results
Preoperative imaging techniques detected 58 metastatic lesions in 28 patients. In 32 % of patients (n?=?9), intraoperative ultrasound detected 24 missed hepatic nodules. In 14 % of patients (n?=?4), contrast-enhanced intraoperative ultrasonography detected an additional six nodules and change in operative management occurred in 18 % of patients. Using univariate analysis, we found three factors significantly related to detection of additional metastases with contrast-enhanced intraoperative ultrasonography: three or more metastases before chemotherapy (p?=?0.047), resolution of at least one metastasis (p?=?0.011), and small liver metastases (largest lesion size ≤20 mm) after chemotherapy (p?=?0.007).Conclusion
In patients undergoing surgery for colorectal liver metastases after chemotherapy, contrast-enhanced intraoperative ultrasonography improved both the sensitivity of intraoperative ultrasonography to detect liver metastases and the R0 hepatic resection rate. 相似文献20.
