PURPOSE: Ex vivo hepatectomy with autotransplantation (EHAT) provides opportunity for R0 resection. As EHAT outcomes after future liver remnant (FLR) augmentation techniques are not well documented, we examine results of EHAT after augmentation for malignant tumors. METHODS: Retrospective analysis of six cases of EHAT was performed. Of these, four occurred after preoperative FLR augmentation between 2018 and 2022. RESULTS: Six patients were offered EHAT of 26 potential candidates...

In patients with extensive colorectal liver metastases (CRLM) and insufficient future liver remnant (FLR) a faster and more effective FLR augmentation than portal vein embolization is the associating liver partition and portal vein ligation in staged hepatectomy (ALPPS). Before ALPPS, the presence of arterial blood supply to the subsequently resected hemiliver must be ensured. We present a case with neoadjuvant-treated CRLM and insufficient FLR who developed a large intrahepatic hematoma after liver biopsy...

Colorectal cancer is the third most common cancer worldwide, and up to 50% of all patients diagnosed will develop metastatic disease. Management of colorectal liver metastases (CRLM) has been constantly improving, aided by newer and more effective chemotherapy agents and the use of multidisciplinary teams. However, the only curative treatment remains surgical resection of the CRLM. Although survival for surgically resected patients has shown modest improvement, this is mostly because of the fact that what is constantly evolving is the indication for resection...

BACKGROUND: Associated liver partition with portal vein ligation for staged hepatectomy (ALPPS) represents a recent strategy to improve resectability of extensive hepatic malignancies. Recent surgical advances, such as the application of technical variants and use of a mini-invasive approach (MI-ALPPS), have been proposed to improve clinical outcomes in terms of morbidity and mortality. METHODS: A total of 119 MI-ALPPS cases from 6 series were identified and discussed to evaluate the feasibility of the procedure and short-term clinical outcomes...

In-situ splitting of the liver before extended resection has gained broad attention. This two-step procedure requires several measures to make an effective and safe procedure. Although the procedure is performed in many institutions, there is no consensus on a uniform technique. The two steps can be divided into different parts and a standardized technique may render the procedure safer and the results will be easier to evaluate. In this paper, we describe a detailed approach to in-situ splitting that allows making both procedures safe, avoids liver necrosis, and is easily reproducible...

The remarkable capacity of regeneration of the liver is well known, although the involved mechanisms are far from being understood. Furthermore, limits concerning the residual functional mass of the liver remain critical in both fields of hepatic resection and transplantation. The aim of the present study was to review the surgical experiments regarding liver regeneration in pigs to promote experimental methodological standardization. The Pubmed, Medline, Scopus, and Cochrane Library databases were searched...

Background Extended hepatectomy (≥ 5 liver segments resection) may be required to have a complete surgical resection and provide the best chance of cure of hepatobiliary tumors. It is associated with high morbidity and mortality but with good perioperative care, its outcomes can be improved. This study was conducted to evaluate the early outcomes of extended hepatectomy at a university hospital in Nepal. Methods For this study, prospectively collected data from all patients who underwent extended hepatectomy from October 2012 to April 2022 were reviewed and analyzed retrospectively...

BACKGROUND AND AIMS: The aim was to establish a liver venous deprivation (LVD) model in rats, compare hepatic hypertrophy between LVD and associated liver partition and portal vein ligation for staged hepatectomy (ALPPS), and explore the underlying mechanisms. METHODS: The LVD or extended-LVD (e-LVD) group received portal vein ligation (PVL) combined with hepatic vein ligation (HVL). The ALPPS or e-ALPPS group received PVL plus parenchyma ligation. Liver regeneration was assessed by measuring the liver weight and performing pathological analysis...

Surgical treatments of advanced tumors have expanded in the last two decades as a result of ad-vances in surgical techniques, advanced interventional radiology methods, improved intensive care unit settings and increased overall life expectancy. Advanced liver tumors represent a broad category from various malignancies such as liver metastasis or native liver tumors. Not uncom-monly these tumors are not amenable to curative treatment and require down-staging, or local control at the initial diagnosis. Herein we discuss the portal vein embolization (PVE), transarterial radioembolization (TARE) with Yttrium-90 (Y-90), and surgical options namely, two-staged hepatectomy (TSH), and associating liver partition and portal vein ligation for staged hepatecto-my (ALPPS) as bridging strategies for definitive surgical treatment...

BACKGROUND: Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) may rescue remnant liver hypertrophy after failure of portal vein embolization (PVE).1 Venous reconstruction is unusual during the first step of ALPPS.2 We report herein an ALPPS for colorectal liver metastases with reconstruction of the hepato-caval junction during the first step. METHODS: After failure of left PVE, a total ALPPS procedure was performed to achieve left trisectionectomy...

BACKGROUND: Several treatments induce liver hypertrophy for patients with liver malignancies but insufficient future liver remnant (FLR). Herein, the aim of this study is to compare the efficacy and safety of existing surgical techniques using network meta-analysis (NMA). METHODS: We searched PubMed, Web of Science, and Cochrane Library from databases for abstracts and full-text articles published from database inception through Feb 2022. The primary outcome was the efficacy of different procedures, including standardized FLR (sFLR) increase, time to hepatectomy, resection rate, and R0 resection margin...

OBJECTIVE: To evaluate the safety and efficacy of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) in the treatment of initially unresectable hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC) and to preliminarily explore the mechanism of rapid growth of the future liver remnant (FLR). METHODS: Twenty-four patients with HBV-associated HCC who underwent ALPPS in our hospital from August 2014 to January 2021 were retrospectively studied...

INTRODUCTION: Induction of liver regeneration represents an option to expand the resectability in patients with expected small future liver remnant (FLR). The aim of this cohort-study is to compare the liver regeneration between different surgical procedures, including novel procedures such as two-stage living donor liver transplantation using a small for size grafts. METHODS: Forty-three patients with colorectal liver metastases were included between 2004 and 2020...

Hepatic epithelioid hemangioendothelioma (HEHE) is a rare, often misdiagnosed malignancy of vascular origin. We describe a case of a 36-year-old, who presented with a burning sensation in his chest on exercise and was believed to have bilobar intrahepatic cholangiocarcinoma. After receiving chemotherapy with partial response, the patient underwent staged resection with modified associating liver partition with portal vein ligation for staged hepatectomy (ALPPS) procedure-laparoscopic radiofrequency-assisted ALPPS (RALPPS)...

Background: The increasing ratio of functional future liver remnant (functional %FLR) after modified associating liver partition and portal vein ligation/embolization for staged hepatectomy (modified-ALPPS) compared with portal vein embolization (PVE) has not been comprehensively evaluated. Purpose: To compare the increasing ratio of functional %FLR between modified-ALPPS and PVE via technetium-99 m-galactosyl human serum albumin single-photon emission computed tomography (99m Tc-GSA SPECT/CT) fusion imaging...

BACKGROUND: The role of tumor-infiltrating lymphocytes (TILs) in the growth and progression of hepatocellular carcinoma (HCC) has attracted widespread attention. AIM: To evaluate the feasibility of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) for massive HCC by exploring the role of TIL in the tumor microenvironment. METHODS: Fifteen massive HCC patients who underwent ALPPS treatment and 46 who underwent hemi-hepatectomy were selected for this study...
