Abstract
To compare the outcomes of modified-Associating Liver Partition and Portal vein Ligation for Staged hepatectomy (ALPPS) techniques with those of conventional-ALPPS. Background ALPPS is an established technique for treating advanced liver tumors. Methods PubMed, Web of Science, and Cochrane databases were searched. The outcomes were assessed by single-arm and 2-arm analyses. Results Seventeen studies containing 335 modified-ALPPS patients were included in single-arm meta-analysis. The estimated blood loss was 267 ± 29 mL (95% confidence interval [CI], 210-324 mL) during the first and 662 ± 51 mL (95% CI, 562-762 mL) during the second stage. The operation time was 166 ± 18 minutes (95% CI, 131-202 minutes) during the first and 225 ± 19 minutes (95% CI, 188-263 minutes) during the second stage. The major morbidity rate was 14% (95% CI, 9%-22%) after the first stage. The future liver remnant hypertrophy rate was 65.2% ± 5% (95% CI, 55%-75%) and the interstage interval was 16 ± 1 days (95% CI, 14-17 days). The dropout rate was 9% (95% CI, 5%-15%). The overall complication rate was 46% (95% CI, 37%-56%) and the major complication rate was 20% (95% CI, 14%-26%). The postoperative mortality rate was 7% (95% CI, 4%-11%). Seven studies containing 215 patients were included in comparative analysis. The hypertrophy rate was not different between 2 methods (mean difference [MD], -5.01; 95% CI, -19.16 to 9.14; P = 0.49). The interstage interval was shorter for partial-ALPPS (MD, 9.43; 95% CI, 3.29-15.58; P = 0.003). The overall complication rate (odds ratio [OR], 10.10; 95% CI, 2.11-48.35; P = 0.004) and mortality rate (OR, 3.74; 95% CI, 1.36-10.26; P = 0.01) were higher in the conventional-ALPPS. Conclusions The hypertrophy rate in partial-ALPPS was similar to conventional-ALPPS. This shows that minimizing the first stage of the operation does not affect hypertrophy. Moreover, the postoperative overall morbidity and mortality rates were lower following partial-ALPPS.

Evolution of associating liver partition and portal vein ligation for staged hepatectomy from 2012 to 2021: A bibliometric analysis. Review. Int J Surg 2022; 103:106648. [PMID: 35513249 DOI: 10.1016/j.ijsu.2022.106648] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Revised: 04/15/2022] [Accepted: 04/19/2022] [Indexed: 02/08/2023]
Abstract
BACKGROUND Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has become increasingly popular during the past few decades, and its indications have extended from patients with normal liver to post-chemotherapy patients and even patients with cirrhosis. However, few studies have assessed the publications in relation to ALPPS. METHODS Web of Science was searched to identify studies related to ALPPS published from 2012 to 2021. The analysis was performed using the bibliometric package (Version 3.1.0) in R software. RESULTS In total, 486 publications were found. These articles were published in 159 journals and authored by 2157 researchers from 694 organizations. The most prolific journal was Annals of Surgery (24 articles and 1170 citations). The most frequently cited article was published in Annals of Surgery (average citations, 72.7; total citations, 727). China was the most productive country for ALPPS publications but had comparatively less interaction with other countries. Both thematic evolution and co-occurrence network analysis showed low numbers of topics such as failure, resection, and safety among the publications but large numbers of highly cited papers on outcomes, prediction, mechanisms, multicenter analysis, and novel procedures such as liver venous deprivation. A total of 196 studies focused the clinical application of ALPPS, and most studies were IDEAL Stages I and II. The specific mechanism of ALPPS liver regeneration remains unclear. CONCLUSIONS This is the first bibliometric analysis offering an overview of the development of ALPPS research publications. Our findings identified prominent studies, countries, institutions, journals, and authors to indicate the future direction of ALPPS research. The role of ALPPS in liver regeneration and the long-term results of ALPPS need further study. Future research directions include comparison of ALPPS with portal vein embolization, liver venous deprivation, and other two-stage hepatectomies as well as patients' quality of life after ALPPS.

Abstract
BACKGROUND To identify the role of physical prehabilitation (PP) in liver regeneration, mitochondrial function, biogenesis, and inflammatory response was investigated after associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) in a rodent model. METHODS Male Wistar rats (n = 60) underwent ALPPS. Animals were divided (n = 30) to the physical prehabilitation group (PP) and sedentary group (S). The animals were exsanguinated before (0 hour) and 24, 48, 72, or 168 hours after the operation. Regeneration rate and proliferation index were assessed. Mitochondrial function, biogenesis, and inflammatory response were evaluated. RESULTS Regeneration rate and Ki67 index were significantly increased in the PP group compared to the S group (P < .001). Due to the changes in oxidative capacity and ATP production rate, the P/O ratio of PP group compared to the S group was significantly increased (P < .05). PP group was characterized by accelerated mitochondrial biogenesis and less intense inflammatory response compared to the S group. CONCLUSIONS To our knowledge, this is the first demonstration of the beneficial effects of PP on liver regeneration, mitochondrial function, biogenesis, and the inflammatory response after ALPPS.

Abstract
Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) represents an innovative surgical technique used for the treatment of large hepatic lesions at high risk for post-resection liver failure due to a small future liver remnant. The most significant amount of literature concerns the use of ALPPS for the treatment of hepatocellular carcinoma (HCC), cholangiocarcinoma (CCC), and colorectal liver metastases (CRLM). On the opposite, few is known about the role of ALPPS for the treatment of uncommon liver pathologies. The objective of the present study was to evaluate the current literature on this topic. A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Eligible articles published up to February 2020 were included using the MEDLINE, Scopus, and Cochrane databases. Among the 486 articles screened, 45 papers met the inclusion criteria, with 136 described cases of ALPPS for rare indications. These 136 cases were reported in 18 different countries. Only in two countries, namely Germany and Brazil, more than ten cases were observed. As for the ALPPS indications, we reported 41 (30.1%) cases of neuroendocrine tumor (NET) metastases, followed by 27 (19.9%) cases of gallbladder cancer (GBC), nine (6.6%) pediatric cases, six (4.4%) gastrointestinal stromal tumors, six (4.4%) adult cases of benign primary liver disease, four (2.9%) adult cases of malignant primary liver disease, and 43 (31.6%) adult cases of malignant secondary liver disease. According to the International ALPPS Registry data, less than 10% of the ALPPS procedures have been performed for the treatment of uncommon liver pathologies. NET and GBC are the unique pathologies with acceptable numerosity. ALPPS for NET appears to be a safe procedure, with satisfactory long-term results. On the opposite, the results observed for the treatment of GBC are poor. However, these data should be considered with caution. The rationale for treating benign pathologies with ALPPS appears to be weak. No definitive response should be given for all the other pathologies. Multicenter studies are needed with the intent to clarify the potentially beneficial effect of ALPPS for their treatment.

Abstract
BACKGROUND Tumors invading the inferior vena cava (IVC) and hepatic veins pose a challenge for surgeons. Hannoun et al.1 were able to show that the resection of these tumors can be done under hypothermia in the Ante-Situm position. Additionally, not only the localization of the tumor but the remaining volume of the remnant liver (FLR) needs to be considered. Schnitzbauer et al.2 were able to induce massive liver hypertrophy in a short period, combining an in-situ split with a portal vein ligation (ALPPS). As this controversial technique has evolved, a safe ALPPS can be performed nowadays.3 To our knowledge, this is the first case that combines a laparoscopic partial ALPPS with an extended resection requiring cardiopulmonary bypass (CPB). METHODS A 58-year-old female presented with a known chronic hepatitis C suffered from a pulmonary embolism, caused by a large, central hepatocellular carcinoma (HCC) with invasion of the suprahepatic IVC and continuous growth into the right atrium (RA). Due to the small FLR, we performed a laparoscopic hybrid-partial-ALPPS with an embolization of the right portal vein. We were able to remove the mass with an Ante-Situm position and resection of the RA under CPB. RESULTS The postoperative course was complicated by posthepatic liver failure and bleeding. However, after 28 days the patient was discharged in a good medical condition. CONCLUSIONS Although tumors invading the suprahepatic IVC and RA pose a surgical challenge, patients can be treated adequately with multidisciplinary management. Advanced HCCs have high recurrence rates; however, a R0 resection might improve overall survival. Wakayma et al. showed in their retrospective study with 13 patients a median survival of 30.8 months when a complete resection was performed.4 Our patient had a disease-free survival of 11 months and is still alive after 24 months. Taking the complexity of the operation and the oncological prospect with a probable recurrence into account, indication for surgery needs to be considered on an individual basis.

Abstract
OBJECTIVE The aim of this study was to use the concept of benchmarking to establish robust and standardized outcome references after the procedure ALPPS (Associating Liver Partition and Portal Vein Ligation for Staged hepatectomy). BACKGROUND AND AIMS The recently developed ALPPS procedure, aiming at removing primarily unresectable liver tumors, has been criticized for safety issues with high variations in the reported morbidity/mortality rates depending on patient, disease, technical characteristics, and center experience. No reference values for relevant outcome parameters are available. METHODS Among 1036 patients registered in the international ALPPS registry, 120 (12%) were benchmark cases fulfilling 4 criteria: patients ≤67 years of age, with colorectal metastases, without simultaneous abdominal procedures, and centers having performed ≥30 cases. Benchmark values, defined as the 75th percentile of the median outcome parameters of the centers, were established for 10 clinically relevant domains. RESULTS The benchmark values were completion of stage 2: ≥96%, postoperative liver failure (ISGLS-criteria) after stage 2: ≤5%, ICU stay after ALPPS stages 1 and 2: ≤1 and ≤2 days, respectively, interstage interval: ≤16 days, hospital stay after ALPPS stage 2: ≤10 days, rates of overall morbidity in combining both stage 1 and 2: ≤65% and for major complications (grade ≥3a): ≤38%, 90-day comprehensive complication index was ≤22, the 30-, 90-day, and 6-month mortality was ≤4%, ≤5%, and 6%, respectively, the overall 1-year, recurrence-free, liver-tumor-free, and extrahepatic disease-free survival was ≥86%, ≥50%, ≥57%, and ≥65%, respectively. CONCLUSIONS This benchmark analysis sets key reference values for ALPPS, indicating similar outcome as other types of major hepatectomies. Benchmark cutoffs offer valid tools not only for comparisons with other procedures, but also to assess higher risk groups of patients or different indications than colorectal metastases.

Undifferentiated embryonal sarcoma of the liver treated with associating liver partition and portal vein ligation for staged hepatectomy in a young adult: A case report. Int J Surg Case Rep 2019; 66:221-227.

Abstract
First Case Report about ALPPS for the treatment of an undifferentiated embryonal sarcoma of the Liver. The feasibility of the ALPPS procedure in a newly faced tumor-entity. Importance of an intraoperative histological evaluation of the parenchyma to estimate the individual risk for liver failure.
Introduction Embryonal sarcomas of the liver (ESL) are extremely rare solid tumors appearing mainly in children. The therapeutic standard for an ESL is a margin free resection combined with chemotherapy. The Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy (ALPPS) procedure as a surgical therapy offers a curative approach for liver tumors of various origins where the future liver remnant (FLR) would be insufficient after a one-staged (extended) hemihepatectomy. Presentation of Case A 19-year-old patient was diagnosed with an undifferentiated embryonal sarcoma of the liver (UESL) in the right liver lobe with oligometastatic spread to the lungs. After neoadjuvant chemotherapy remission was enough to plan a resection of the liver tumor. During the operation we changed our strategy from one-stage hepatectomy to ALPPS because of borderline FLR and macroscopic and histologic liver damage to avoid posthepatectomy liver failure. The interstage and postoperative course of the patient was uneventful beside postoperative bile leakage, which was treated by interventional drainage and stenting. Discussion The ALPPS-procedure as a comparatively new surgery was considered over a portal vein ligation or embolization. ALPPS shows a faster hypertrophy compared to standard one-staged hemihepatectomy with decreased or similar proliferation, apoptosis or angiogenesis (at least for CRLM) Conclusion In experienced centers the ALPPS-procedure is evolving as the safer approach in hemihepatectomys where the FLR is critical. Additionally, ALPPS can serve as an intraoperative option when liver volume and quality seem not to be sufficient and is to be considered when facing new tumor-entities.

Rapid Induction of Liver Regeneration for Major Hepatectomy (REBIRTH): A Randomized Controlled Trial of Portal Vein Embolisation versus ALPPS Assisted with Radiofrequency. Cancers (Basel) 2019; 11:cancers11030302.

Abstract
To avoid liver insufficiency following major hepatic resection, portal vein embolisation (PVE) is used to induce liver hypertrophy pre-operatively. Associating liver partition with portal vein ligation for staged hepatectomy assisted with radiofrequency (RALPPS) was introduced as an alternative method. A randomized controlled trial comparing PVE with RALPPS for the pre-operative manipulation of liver volume in patients with a future liver remnant volume (FLRV) ≤25% (or ≤35% if receiving preoperative chemotherapy) was conducted. The primary endpoint was increase in size of the FLRV. The secondary endpoints were length of time taken for the volume gain, morbidity, operation length and post-operative liver function. Between July 2015 and October 2017, 57 patients were randomised to RALPPS (n = 29) and PVE (n = 28). The mean percentage of increase in the FLRV was 80.7 ± 13.7% after a median 20 days following RALPPS compared to 18.4 ± 9.8% after 35 days (p < 0.001) following PVE. Twenty-four patients after RALPPS and 21 after PVE underwent stage-2 operation. Final resection was achieved in 92.3% and 66.6% patients in RALPPS and PVE, respectively (p = 0.007). There was no difference in morbidity, and one 30-day mortality after RALPPS (p = 0.991) was reported. RALPPS is more effective than PVE in increasing FLRV and the number of patients for surgical resection.

Abstract
BACKGROUND Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is a two-stage strategy to induce rapid regeneration of the remnant liver. The technique has been associated with high mortality and morbidity rates. This study aimed to evaluate mitochondrial function, biogenesis and morphology during ALPPS-induced liver regeneration. METHODS Male Wistar rats (n = 100) underwent portal vein ligation (PVL) or ALPPS. The animals were killed at 0 h (without operation), and 24, 48, 72 or 168 h after intervention. Regeneration rate and proliferation index were assessed. Mitochondrial oxygen consumption and adenosine 5'-triphosphate (ATP) production were measured. Mitochondrial biogenesis was evaluated by protein level measurements of peroxisome proliferator-activated receptor γ co-activator (PGC) 1-α, nuclear respiratory factor (NRF) 1 and 2, and mitochondrial transcription factor α. Mitochondrial morphology was evaluated by electron microscopy. RESULTS Regeneration rate and Ki-67 index were significantly raised in the ALPPS group compared with the PVL group (regeneration rate at 168 h: mean(s.d.) 291·2(21·4) versus 245·1(13·8) per cent, P < 0·001; Ki-67 index at 24 h: 86·9(4·6) versus 66·2(4·9) per cent, P < 0·001). In the ALPPS group, mitochondrial function was impaired 48 h after the intervention compared with that in the PVL group (induced ATP production); (complex I: 361·9(72·3) versus 629·7(165·8) nmol per min per mg, P = 0·038; complex II: 517·5(48·8) versus 794·8(170·4) nmol per min per mg, P = 0·044). Markers of mitochondrial biogenesis were significantly lower 48 and 72 h after ALPPS compared with PVL (PGC1-α at 48 h: 0·61-fold decrease, P = 0·045; NRF1 at 48 h: 0·48-fold decrease, P = 0·028). Mitochondrial size decreased significantly after ALPPS (0·26(0·05) versus 0·40(0·07) μm2 ; P = 0·034). CONCLUSION Impaired mitochondrial function and biogenesis, along with the rapid energy-demanding cell proliferation, may cause hepatocyte dysfunction after ALPPS. Surgical relevance Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is a well known surgical strategy that combines liver partition and portal vein ligation. This method induces immense regeneration in the future liver remnant. The rapid volume increase is of benefit for resectability, but the mortality and morbidity rates of ALPPS are strikingly high. Moreover, lagging functional recovery of the remnant liver has been reported recently. In this translational study, ALPPS caused an overwhelming inflammatory response that interfered with the peroxisome proliferator-activated receptor γ co-activator 1-α-coordinated, stress-induced, mitochondrial biogenesis pathway. This resulted in the accumulation of immature and malfunctioning mitochondria in hepatocytes during the early phase of liver regeneration (bioenergetic destabilization). These findings might explain some of the high morbidity if confirmed in patients.
