Abstract
Background and aims Colorectal liver metastases (CRLMs) represent the most prevalent form of secondary liver tumors, and insufficient future liver remnant (FLR) often leads to unresectability. To tackle this challenge, various methods for stimulating liver hypertrophy have been developed including portal vein embolization (PVE), associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) and the newest one, liver venous deprivation (LVD). ALPPS was thoroughly studied over the last decade and it has been shown to induce rapid and intensive FLR hypertrophy. The objective of this study was to assess whether the localization of the liver transection line during the initial stage of ALPPS correlates with the degree of FLR hypertrophy. Methods A retrospective, multicentric study was conducted, and we analyzed all consecutive patients with CRLMs who underwent ALPPS over the eight-year period. Patients were categorized into two groups based on the type of resection-right trisectionectomy (ERH) or right hemihepatectomy (RH) respectively. The degree of hypertrophy (DH), its correlation with FLR and postoperative outcomes were assessed. Results The cohort consisted of 136 patients (72 in the ERH group and 64 in the RH group). Baseline characteristics, hypertrophy interval, and total liver volume showed no significant differences between the groups. DH was greater in the ERH group (83.2% vs. 62.5%, p = 0.025). A strong negative correlation was observed between FLR volume and DH in both groups. Postoperative outcomes and one-year survival were comparable between the groups. Conclusions FLR hypertrophy is influenced by the localization of the liver transection line in ALPPS. Furthermore, correlation analysis indicated that a smaller estimated FLR is associated with greater DH. No statistical difference in outcomes was noted between the groups.

Abstract
BACKGROUND Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is a two-stage strategy that may increase hepatic tumour resectability and reduce postoperative liver failure rate by inducing rapid hypertrophy of the future liver remnant (FLR). Pathophysiological mechanisms after the first stage of ALPPS are poorly understood. METHODS An ALPPS model was established in rabbits with liver VX2 tumour. The pathophysiological mechanisms after the first stage of ALPPS in the FLR and tumour were assessed by multiplexed positron emission tomography (PET) tracers, dynamic contrast-enhanced MRI (DCE-MRI) and histopathology. RESULTS Tumour volume in the ALPPS model differed from post-stage 1 ALPPS at day 14 compared to control animals. 18F-FDG uptake of tumour increased from day 7 onwards in the ALPPS model. Valid volumetric function measured by 18F-methylcholine PET showed good values in accurately monitoring dynamics and time window for functional liver regeneration (days 3 to 7). DCE-MRI revealed changes in the vascular hyperpermeability function, with a peak on day 7 for tumour and FLR. CONCLUSION Molecular and functional imaging are promising non-invasive methods to investigate the pathophysiological mechanisms of ALPPS with potential for clinical application.

Abstract
BACKGROUND Primary and secondary liver tumors are not always amenable to resection due to location and size. Inadequate future liver remnant (FLR) may prevent patients from having a curative resection or may result in increased postoperative morbidity and mortality from complications related to small-for-size syndrome (SFSS). DATA SOURCES This comprehensive review analyzed the principles, mechanism and risk factors associated with SFSS and presented current available options in the evaluation of FLR when planning liver surgery. In addition, it provided a detailed description of specific modalities that can be used before, during or after surgery, in order to optimize the conditions for a safe resection and minimize the risk of SFSS. RESULTS Several methods which aim to reduce tumor burden, preserve healthy liver parenchyma, induce hypertrophy of FLR or prevent postoperative complications help minimize the risk of SFSS. CONCLUSIONS With those techniques the indications of radical treatment for patients with liver tumors have significantly expanded. The successful outcome depends on appropriate patient selection, the individualization and modification of interventions and the right timing of surgery.

Abstract
BACKGROUND Hepatocellular carcinoma is an aggressive tumor, and its latency and lack of clinical symptoms mean that most patients are already in the late stage when diagnosed. Large tumor volume and metastasis are the main reasons for not attempting surgery. Portal vein embolization and associated liver partition and portal vein ligation for staged hepatectomy are commonly used in clinical practice to increase the volume of remnant liver to allow surgical resection; however, research in this area is currently lacking.
CASE SUMMARY A 48-year-old male patient with a history of viral hepatitis B for at least 30 years attended our center with a hepatic space-occupying lesion detected 3 d previously. Enhanced computed tomography scanning of the upper abdomen revealed a large mass in the right lobe of the liver, centered on the right posterior lobe, with the larger section measuring about 14 cm × 10 cm × 14 cm. He successfully underwent conversion therapy for a large right liver tumor after combined hepatic artery ligation and transcatheter arterial chemoembolization, and finally had an opportunity to undergo right hemi-hepatectomy and cholecystectomy. He remained asymptomatic with no obvious abnormalities on computed tomography scanning review at 2 mo after surgery.
CONCLUSION This case highlights new ideas and provides a reference for conversion therapy of large liver tumors.

Abstract
PURPOSE We compared the clinical outcomes of modified procedures for associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) based on a risk-reduced strategy with those of classic ALPPS procedures in treating large liver carcinoma. MATERIALS AND METHODS Short-term outcomes, increases in future liver remnant (FLR) and functional FLR (FFLR), and overall survival (OS) were compared between 45 consecutive patients treated with modified ALPPS procedures and 34 patients treated with classic ALPPS procedures. RESULTS Clinical outcomes after the 1st-stage operation markedly improved with the modified procedures. Although the proportions of liver cirrhosis and hepatocellular carcinoma were higher in the modified group, the mortality and incidence of severe complications did not increase. FLR and FFLR hypertrophy at 1 week after the 1st-stage operation were similar in both groups; however, kinetic growth rates in the modified group were lower. OS rates were similar. CONCLUSION Modified ALPPS procedures could be safely applied to provide long-term survival for patients with liver cirrhosis without sufficient FLR.

Abstract
Primary liver cancer has an insidious onset and no specific symptoms at early stage. Most patients are in the middle or advanced stage when diagnosed, and only 20%-40% of patients meet the criteria for radical resection. At present, surgical resection is still the main radical treatment for primary liver cancer, but factors such as liver function decompensation, too large tumor volume, too small future liver remnant, intrahepatic multiple metastasis, tumor thrombus invading the large vessels or bile duct, and distant metastasis limit the application of surgical resection or liver transplantation. In recent years, with the advances of basic research of primary liver cancer, the development of surgical techniques and equipment, as well as the development of new molecular targeted drugs and immunotherapy drugs, a part of unresectable patients with primary liver cancer can receive conversion therapy to improve liver function, minimize tumor volume, minimize or inactivate tumor thrombus, and increase the residual liver volume. Following conversion therapy, patients with primary liver cancer can undergo surgical resection or liver transplantation, which greatly improve the therapeutic efficacy and patient survival.

Abstract
PURPOSE Here, we analyse the technical modification of the ALPPS procedure, ligating the middle hepatic vein during the first step of the operation to enhance remnant liver hypertrophy. METHODS In 20 of 37 ALPPS procedures, the middle hepatic vein was ligated during the first step. Hypertrophy of the functional remnant liver volume was assessed in addition to postoperative courses. RESULTS Volumetric analysis showed a significant volume increase, especially for patients with colorectal metastases. Pre-existing liver parenchyma damage (odds ratio = 0.717, p = 0.017) and preoperative chemotherapy were found to be significant predictors (odds ratio = 0.803, p = 0.045) of higher morbidity and mortality. In addition, a survival benefit for maintenance of middle hepatic vein was shown. CONCLUSION This technical modification of the ALPPS procedure can accentuate future liver remnant volume hypertrophy. The higher morbidity and mortality observed are most likely associated with pre-existing parenchymal damage within this group.

Abstract
BACKGROUND Resection with trisectionectomy may necessitate liver molding for adequate future liver remnant (FLR), and subsequent complications can impact return to intended oncologic therapy (RIOT). This study evaluated whether a difference in RIOT exists with the use of molding and between liver molding techniques (associating liver partition and portal vein ligation for staged hepatectomy [ALPPS] and portal vein embolization [PVE]) with trisectionectomy. METHODS A retrospective review evaluated trisectionectomies for malignancy. Outcomes were compared with and without molding, and RIOT was determined. RESULTS Fifty-one patients underwent trisectionectomy: 11 ALPPS, 14 PVE, 26 without molding. 73% of ALPPS, 64% of PVE, and 58% without molding achieved RIOT (P = .971). There were no differences found in baseline characteristics, R0 rate, length of stay, readmission, complications, or mortality. Time to RIOT was significantly different (ALPPS: 3.3 months; PVE: 5.2 months; none: 2.4 months, P = .0203). There were no differences in recurrence or survival. CONCLUSIONS Liver molding should not cause apprehension as there are no differences in achieving RIOT. Although technique alters time to RIOT, this does not translate into improved outcomes, implicating disease biology, and regeneration stimulus.

Abstract
BACKGROUND Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) for intrahepatic cholangiocarcinoma (ICC) demonstrated good long-term outcomes1 and can increase the rate of resectability in locally advanced ICC;2 however, the rates of postoperative complications (Clavien-Dindo grade III) and mortality range between 13.6 and 44% and 0 and 29%, respectively.3 Minimally invasive strategies may reduce the risk of postoperative morbidity, with the same oncologic outcomes.4,5 We report the first case of full robotic ALPPS for advanced ICC. METHODS The patient was a 61-year-old male diagnosed with a 6.5 cm ICC involving segments IV, V, and VIII. The total clean liver volume was 1553 cc3, with a future liver remnant (FLR) volume of 21.6% (segments I, II, and III: 337 cc3). The procedure was performed by a senior hepato-pancreato-biliary (HPB) surgeon at the robotic console and a junior HPB surgeon at the table side. RESULTS Computed tomography scan on postoperative day (POD) 9 after stage 1 showed that FLR increased up to 38%. The indocyanine green clearance test showed a plasma disappearance rate of 19.8%/min and a retention rate at 15 min of 5.1%; complete blood tests are available at the end of the video. ALPPS was completed on POD 14, the postoperative course was uneventful, and the patient was discharged in good general condition on POD 5. Final pathology showed a 6 cm ICC, G3, R0 margin (10 mm), T2-N0-M0. The patient started adjuvant capecitabine, and after 6 months was in good general condition without signs of local or systemic recurrence. CONCLUSIONS Robotic ALPPS combines the opportunity to perform a curative resection in patients presenting with insufficient FLR with the advantages of a minimally invasive approach. It is feasible and oncologically accurate for ICC when performed in fully trained HPB centers.

Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy for Unresectable Hepatitis B Virus-related Hepatocellular Carcinoma: A Single Center Study of 45 Patients. Ann Surg 2020; 271:534-541.

Abstract
OBJECTIVE The aim of the study is to assess the efficacy and safety of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) in patients with hepatitis B virus-related hepatocellular carcinoma (HCC). BACKGROUND ALPSS allows curative resection of conventionally-unresectable liver tumors. However, its role in HCC is largely unknown. METHODS Consecutive HCC patients who underwent ALPPS at our center between April 2013 and September 2017 were retrospectively studied. The oncological results were compared with patients receiving transcatheter arterial chemoembolization (TACE), and patients undergoing one-stage resection by using propensity score matching (PSM) analysis. RESULTS The median tumor diameter was 13 cm (range: 6-22 cm) in patients with a single tumor (n = 28), whereas the median total tumor diameter was 12 cm (range: 9-31 cm) in patients with multiple tumors (n = 17). After stage-1 ALPPS, the median future liver remnant (FLR) increased by 56.8%. The stage-2 ALPPS was completed in 41 patients (91.1%) after a median of 12 days. The 90-day mortality rate was 11.1% (5/45). The overall survival (OS) rates at 1- and 3-year were 64.2% and 60.2%, whereas the disease-free survival (DFS) rates at 1 and 3 years were 47.6% and 43.9%, respectively. On PSM analysis, the long-term survival of patients undergoing ALPPS was significantly better than those receiving TACE (OS, P = 0.004; DFS, P < 0.0001) and similar to those subjected to one-stage liver resection (OS, P = 0.514; DFS, P = 0.849). CONCLUSIONS The long-term survival after ALPPS was significantly better than TACE, and similar to those after one-stage liver resection. ALPPS is a viable treatment option for patients with unresectable HCC in selected patients.

Abstract
PURPOSE Surgical resection constitutes the mainstay of curative treatment for intrahepatic cholangiocarcinoma (iCCA). Complete tumor clearance can only be achieved with extended liver resections and as such, associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) may facilitate surgical resectability. The present study aims to evaluate the technical feasibility and oncologic outcome of ALPPS in iCCA. METHODS A set of 14 patients who underwent ALPPS in a single center between 2011 and 2017 were statistically analyzed for perioperative and oncologic outcome. RESULTS Of all patients undergoing stage 1 of ALPPS, 12 (86%) patients were subsequently completed in stage 2 surgery. Patients who completed the ALPPS procedure showed a median overall survival (OS) of 4.2 years and a 3-year survival of 64%. Individuals without lymphatic metastases (n = 7) were all alive 1 year after surgery and if deceased, they died more than 4 years after surgery, while no patient with lymphatic metastases (n = 5) was alive 1 year after surgery. CONCLUSION This is the largest single-center experience of ALPPS in iCCA currently available in the literature showing excellent technical feasibility and encouraging overall survival in these patients.

Abstract
The complete resection offers the best long-term survival for advanced hepatocellular carcinoma patients. ALPPS as a choice of resection, how is its outcome compared to one-stage resection, liver transplantation and TACE? This retrospective study included 20 ALPPS patients. To minimize the effect of confounding influences of measured covariates, PSM was performed. The overall survival (OS), morbidity, mortality and the increasing rate, KGR were analyzed. The OS in ALPPS group is 27.4 (±3.8 months) moths and the TACE group is 13.5(±1.2 months) (P < .001), LT group is 41.3 (±3.2 months) (P = .048), Resection group is 31.8 (±2.6 months) (P = .368). And the medium increasing volume is 209.5 cm (±61.5 cm) with the increasing ratio 52.4% (+26.9%). The ALPPS is a feasible treatment for HCC patients and it provides a better long-term survival than TACE and it is similar to Resection, less than LT.

Abstract
BACKGROUND Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has becoming ever more recognized in the treatment of hepatocellular carcinoma (HCC). Nevertheless, long-term survival rate and postoperative complications are far from ideal, mainly since the majority of patients treated with ALPPS surgery have large or multiple lesions and microvascular tumor thrombus.
CASE SUMMARY We present the case of a 47-year-old male patient with a huge right hepatic mass and an estimated insufficient residual liver, who was successfully treated with ALPPS surgery and apatinib. Postoperative pathology revealed HCC with several significant microvascular embolisms. Twenty months after operation, no tumor reoccurrence was observed.
CONCLUSION Our case indicated that combined targeted drug therapy with ALPPS can lead to long-term survival for patients with large HCC.

Abstract
The techniques of portal vein embolization (PVE) or ligation (PVL) have the goals of combining an induced atrophy of metastatic segments with the rapid relative compensatory hypertrophy of the postresection future liver remnant (FLR). Our study examines the anatomy of right-left hepatic lobar venous connections in the adult cadaver using corrosion cast analysis in an effort to define some of the inherent anatomical reasons why both PVL and PVE may be technically unsuccessful. Corrosion cast models of 215 cadaveric liver specimens were evaluated for hepatopetal venous blood flow, with a particular emphasis on cholecystic venous drainage patterns, including 57 cases prepared after lobar portal venous ligation. In 88.8 per cent of corrosion casts, there was a segmental venous communication between the gallbladder and all segments of the liver, except segment II. There was cystic vein drainage directly into a main lobar branch or directly into the portal vein itself in 11.2 per cent of cases. In all 57 cases, after portal lobar venous division, in situ cystic veins allowed persistent venous communication between lobes. Our cadaveric corrosion cast study has suggested that there is extensive intrahepatic cholecystic venous drainage to many segments of the liver. Perfusion from the gallbladder may potentially contribute to a limited response to procedures which interrupt the portal venous flow and could affect their capacity to induce an adequate FLR which would permit a wider hepatectomy.

Abstract
When very large hepatocellular carcinomas (HCCs) and intrahepatic cholangiocarcinoma (IHCCs) with insufficient future liver remnants are treated using associating liver partition and portal vein ligation for staged hepatectomy (ALPPS), the outcome is often poor. We therefore tested the efficacy of a modified version of that technique, tourniquet-ALPPS. A review of the literature examining outcomes of HCC and IHCC patients treated with ALPPS revealed the incidences of morbidity ≥ III and postoperative mortality to be respectively 20.7% and 16.1% among HCC patients and 50% and 45.4% among IHCC patients. In the present case series, in which HCC and IHCC patients were treated with tourniquet-ALPPS, median tumor size was 100 mm (range: 70–200 mm). After surgical stage I, there was no morbidity, no mortality and the median future liver remnant had increased at day 7 by 76%. In surgical stage II, 100% of tumors were resectable (8 right trisectionectomies, 5 with inferior vena cava resection). Two patients experienced serious morbidity ≥ IIIB and 1 patient died (11%). One- and 3-year overall survival was 75% and 60%, respectively. Thus tourniquet-ALPPS appears to be an effective alternative to classical ALPPS for the treatment of patients with HCC or IHCC.

Abstract
Monosegment 4±1 Associating Liver Partition and Portal Vein ligation for Staged hepatectomy (ALPPS) for bilateral colorectal liver metastases decreases the risk of drop-out of two stage hepatectomy, triggering a rapid and significant increase in future liver remnant (FLR) with promising oncological outcomes. We report two cases of segment 4+1 monosegment ALPPS for multiple colorectal liver metastases performed at our institution. In the literature, seven similar cases have been reported. Short and long term outcomes of our two patients were reported along with a review of data from the literature. Our patients showed a FLR increase from 13% to 37% and from 14% to 41% of total liver volume, respectively. This was compared to a median growth from 19% at baseline to 34% before stage 2, in the literature. After 20 and 27 months since resection both patients are alive and disease-free. In the literature, median overall survival and disease free survival were 13 months (range, 5-24 months) and 5 months (range, 3-23 months), respectively. Segment 4±1 ALPPS is associated with promising oncological outcomes and a significant FLR growth. It may be safely performed in selected patients as a salvage procedure, reducing the risk of the dropout of two-stage hepatectomy.

Abstract
Associating Liver Partition and Portal vein ligation for Staged hepatectomy (ALPPS) is a novel method to prevent post-hepatectomy hepatic failure. We present a case of periductal infiltrating intrahepatic cholangiocarcinoma undergone ALPPS, that was conducted as intraoperative choice instead of conducting preoperative portal vein embolization (PVE). A 65-year-old male patient was to undergo extended right posterior sectionectomy, but the operation plan was changed to conduct right hepatectomy with/without bile duct resection due to invasion of the right hepatic duct. After deciding to conduct ALPPS, we stopped further perihilar dissection and liver was transected. The right portal vein was ligated and Surgicel was densely packed between the transected hemilivers. There was rapid regeneration of the left liver on computed tomography follow-up, thus the second-stage right hepatectomy was conducted 10 days after the first-stage operation. Bile duct resection (BDR) was not performed due to heavy perihilar adhesion and inflammation, but fortunately tumor-negative bile duct resection margin was achieved after meticulous dissection. This patient recovered uneventfully and discharged nine days after the second-stage right hepatectomy. Thereafter he underwent concurrent chemoradiation therapy. He is doing well so far without evidence of tumor recurrence for 20 months after operation. In conclusion, this case suggests that ALPPS may be applied to an unexpected situation requiring PVE, but ALPPS is not recommend for treatment of perihilar malignancy requiring BDR.

Abstract
Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has recently been introduced as a new surgical technique to increase future liver remnant in patients with marginal liver volume contemplating major liver resection. We herein present two cases. Case 1: a 68-year-old male patient with colorectal liver metastasis was referred to our department. The future liver remnant (FLR) was 22%. We performed first-stage ALPPS and colorectal surgery concurrently and second stage operation was performed 8 days later. The patient discharged 28 days after the first-stage ALPPS procedure. Case 2: a 69-year-old male patient with a huge hepatic mass was referred for hepatic surgery. The FLR was 19%. After the first stage of the ALPPS procedure, acute renal failure and posthepatectomy liver failure occurred. The patient began to recover on the 5th postoperative day. At 10 days after the first stage, the patient completed the second-stage procedure. The patient discharged 23 days after the first-stage ALPPS procedure. So far many studies are currently underway to identify factors associated with the morbidity and mortality of the ALPPS procedure, it is necessary to continue follow-up studies and observe the results.

Abstract
AIM To evaluate safety and outcomes of a new technique for extreme hepatic resections with preservation of segment 4 only.
METHODS The new method of extreme liver resection consists of a two-stage hepatectomy. The first stage involves a right hepatectomy with middle hepatic vein preservation and induction of left lobe congestion; the second stage involves a left lobectomy. Thus, the remnant liver is represented by the segment 4 only (with or without segment 1, ± S1). Five patients underwent the new two-stage hepatectomy (congestion group). Data from volumetric assessment made before the second stage was compared with that of 10 matched patients (comparison group) that underwent a single-stage right hepatectomy with middle hepatic vein preservation.
RESULTS The two stages of the procedure were successfully carried out on all 5 patients. For the congestion group, the overall volume of the left hemiliver had increased 103% (mean increase from 438 mL to 890 mL) at 4 wk after the first stage of the procedure. Hypertrophy of the future liver remnant (i.e., segment 4 ± S1) was higher than that of segments 2 and 3 (144% vs 54%, respectively, P < 0.05). The median remnant liver volume-to-body weight ratio was 0.3 (range, 0.28-0.40) before the first stage and 0.8 (range, 0.45-0.97) before the second stage. For the comparison group, the rate of hypertrophy of the left liver after right hepatectomy with middle hepatic vein preservation was 116% ± 34%. Hypertrophy rates of segments 2 and 3 (123% ± 47%) and of segment 4 (108% ± 60%, P > 0.05) were proportional. The mean preoperative volume of segments 2 and 3 was 256 ± 64 cc and increased to 572 ± 257 cc after right hepatectomy. Mean preoperative volume of segment 4 increased from 211 ± 75 cc to 439 ± 180 cc after surgery.
CONCLUSION The proposed method for extreme hepatectomy with preservation of segment 4 only represents a technique that could allow complete resection of multiple bilateral liver metastases.
