Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) allows extended hepatectomy in patients with an extremely small future liver remnant (FLR). Current rodent models of ALPPS do not include resection resulting in insufficient-for-survival FLR, or they do incorporate liver mass reduction prior to ALPPS. Differences in FLR volume and surgical procedures could bias our understanding of physiological and hemodynamic mechanisms. We aimed to establish a rat ALPPS model with minimal FLR without prior parenchymal resection...

BACKGROUND: Liver hypertrophy induced by partial portal vein occlusion (PVL) is accelerated by adding simultaneous parenchymal transection ("ALPPS procedure"). This preclinical experimental study in pigs tests the hypothesis that simultaneous ligation of portal and hepatic veins of the liver also accelerates regeneration by abrogation of porto-portal collaterals without need for operative transection. METHODS: A pig model of portal vein occlusion was compared with the novel model of simultaneous portal and hepatic vein occlusion, where major hepatic veins draining the portal vein-deprived lobe were identified with intraoperative ultrasonography and ligated using pledgeted transparenchymal sutures...

BACKGROUND: Based on the International ALPPS registry, we have recently proposed two easily applicable risk models (pre-stage1 and 2) for predicting 90-day mortality in ALPPS but a validation of both models has not been performed yet. METHODS: The validation cohort (VC) was composed of subsequent cases of the ALPPS registry and cases of centers outside the ALPPS registry. RESULTS: The VC was composed of a total of 258 patients including 70 patients outside the ALPPS registry with 32 cases of early mortalities (12%)...

BACKGROUND: Associating liver partition and portal vein ligation (ALPPS) is a promising two-step hepatectomy that is beneficial for accumulative regeneration of the future liver remnant (FLR) and avoids postoperative liver failure. AIMS: Our study aimed to evaluate whether nonalcoholic fatty liver disease affected the liver regeneration induced by ALPPS. METHODS: Sprague-Dawley rats fed a high-fat diet were used to construct the NAFLD model...

BACKGROUND The associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is an important tool to induce fast liver hypertrophy. The degree of hepatic fibrosis/cirrhosis in patients with HCC negatively impacts their health, and the risk of liver failure is always present. In these cases, liver transplantation may be necessary as a rescue procedure. We present the case of a patient with HCC who underwent ALPPS and developed liver failure. A living donor liver transplant was performed as a rescue procedure...

Colorectal carcinoma (CRC) is the third leading cause of cancer-related death in the United States. The liver is the most frequent site of metastasis and a key determinant of survival in patients with isolated colorectal liver metastasis (CRLM). Surgical resection remains the only hope for prolonged survival in patients with CRLM. However, most patients are deemed to be unresectable at presentation due to a small future liver remnant (FLR) and fear of post-hepatectomy liver failure. Procedures such as portal vein ligation or embolization (PVL/PVE) followed by hepatectomy have been established as standard methods to increase FLR volume, but have limitations dependent upon extent of disease and patient's ability to grow the liver remnant...

OBJECTIVE: After recent evaluations of the ALPPS registry, with perioperative results sobering in particular for central bile duct carcinomas, the initial euphoria for this procedure disappeared. It is thus desirable to modify the concept of reducing the invasiveness and high complication rate of the procedure. INDICATIONS: Below we report a 72-year-old female patient with a gallbladder carcinoma locally infiltrating and metastatic to segments 4 b and 5. Due to a too small future liver remnant volume of segments 1 - 3 before planned extended right hemihepatectomy, we planned a laparoscopic partial PVE-ALPPS for hypertrophy induction...

BACKGROUND: Excessive increase of portal flow and pressure following extended hepatectomy have been associated to insufficient growth or function of the future liver remnant (FLR), with the risk of post-hepatectomy liver failure (PHLF). We prospectively assess the influence of liver hemodynamics on FLR regeneration and function in Associating Liver Partition and Portal vein ligation for Staged hepatectomy (ALPPS). METHODS: Twenty-three patients underwent ALPPS; liver hemodynamics were assessed throughout the procedures...

The ALPPS is a technique that allows achieving hepatic resection by a rapid future liver remnant hypertrophy. The aim of this study was to report the experience of an Italian center with ALPPS in patients with liver tumors. A retrospective analysis of patients undergoing ALPPS between 2012 and 2017 was performed. Patients' characteristics and disease presentation, increase in future liver remnant (FLR) as well as intraoperative and postoperative short- and long-term outcomes were evaluated. A total of 24 patients underwent the ALPPS procedure: 17 procedures for hepatocarcinoma (HCC), 5 for colorectal liver metastases (CRLM), 1 for cholangiocarcinoma (CC) and 1 for Merkel Cell Carcinoma liver metastasis (MCCLM)...

BACKGROUND: The associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) procedure promotes the proliferation of the future liver remnant, but evidence to support the feasibility of ALPPS in livers with fibrosis is needed. Therefore the aim of this study was to establish a fibrotic ALPPS model in the rat to compare the capacity of regeneration in the remnant liver with or without fibrosis. METHODS: In our study we first established a thioacetamide-induced fibrotic ALPPS model in rats...

Twenty five percent of total liver volume (TLV) is considered as the ideal functional liver remnant (FLR) in major liver resections. In patients with macro-vesicular steatosis, early cirrhosis, and post-neoadjuvant chemotherapy (NACT), hepatocellular injury is common. In such instances, up to 40% of FLR may be required. So in cases of marginal FLR, pre-operative portal vein (PV) embolization or two-stage hepatectomy with PV occlusion is used. Both of which take up to 14 weeks between stages and 30% of patients fail to reach the second resection either due to inadequate FLR growth or disease progression...
