Comparative Study of the Initial Experience in Performing Robotic and Laparoscopic Right Hepatectomy with Technical Description of the Robotic Techni…

2017

<b><i>Background:</i></b> Despite potential benefits of robotic liver surgery, it is still considered a “development in progress” technique. <b><i>Methods:</i></b> The outcomes of 14 patients undergoing robotic right hepatectomy were analyzed and compared with the results of 20 laparoscopic right hepatectomies consecutively performed by the same young surgeon. <b><i>Results:</i></b> The overall mean operative time was less in robotic arm (425 ± 139 vs. 565.18 ± 183.73, <i>p</i> = 0.022) and the estimated blood loss was similar (335.15 ± 139.8 vs. 423.95 ± 205.15, <i>p</i> = 0.17); no blood transf…

Combined interleukin 6 and soluble interleukin 6 receptor accelerates murine liver regeneration.

2000

Abstract Background & Aims: Liver regeneration after loss of hepatic tissue leads to hepatocyte and nonparenchymal cell proliferation and rapid restoration of liver parenchyma. Interleukin (IL)-6 is a key inducer of transcription factors involved in liver regeneration. Whenever IL-6 activates target cells, it binds to a specific IL-6 receptor (IL-6R). The IL-6/IL-6R complex then associates with the signal transducer gp130, leading to activation of intracellular signaling. Methods: We have recently constructed the designer cytokine Hyper-IL-6 consisting of soluble IL-6R covalently linked to IL-6, which directly stimulates gp130 even in the absence of membrane-bound IL-6R. We compared the inf…

LAPAROSCOPIC LEFT LIVER SECTIONECTOMY (LLLS) FOR PEDIATRIC LIVING RELATED LIVER TRANSPLANTATION (LRLT)

2011

PURPOSE: LRLT in children is a method to provide organs for transplantation. We report 2 cases of LLLS for pediatric LRLT. METHOD: Donor position: lithotomy with surgeon in French position. Trocars: three 12 mm, placed 2 cm upper the supra-umbilical mid-line and sub-costal bi-lateral on the nipple lines; one 5 mm in epigastrium. Special instrumentation: harmonic scissor, ligasure®, Hem-O-Lock clips, and Endo Catch-II® bag. Main steps: division of round, falciform, left triangular ligaments and of lesser omentum; inspection of anatomy; hepatic hilum dissection with exposure of the left hepatic artery; dissection of the right side of the falciform ligament with exposure of the left branch of …

Intrahepatic cholangiocarcinoma: Limitations for resectability, current surgical concepts and future perspectives.

2020

Intrahepatic cholangiocarcinoma (iCCA) is the second most common hepatic malignancy and its incidence has been shown to increase significantly during the past decades. Complete surgical resection is currently acknowledged as the only curative treatment option able to provide adequate long-term outcomes. We herein review technical, functional and oncologic limitations for resectability, discuss current surgical aspects as well as highlight the fields in which future research and practice should focus on in order to ameliorate long-term outcomes in patients with iCCA.

Nucleosome-specific, Time-dependent Changes in Histone Modifications during Activation of the Early Growth Response 1 (Egr1) Gene

2014

Histone post-translational modifications and nucleosome remodeling are coordinate events involved in eukaryotic transcriptional regulation. There are relatively few data on the time course with which these events occur in individual nucleosomes. As a contribution to fill this gap, we first describe the nature and time course of structural changes in the nucleosomes -2, -1, and +1 of the murine Egr1 gene upon induction. To initiate the transient activation of the gene, we used the stimulation of MLP29 cells with phorbol esters and the in vivo activation after partial hepatectomy. In both models, nucleosomes -1 and +1 are partially evicted, whereas nucleosomes +1 and -2 slide downstream durin…

Persistent episomal transgene expression in liver following delivery of a scaffold/matrix attachment region containing non-viral vector

2008

An ideal gene therapy vector should enable persistent transgene expression without limitations of safety and reproducibility. Here we report the development of a non-viral episomal plasmid DNA (pDNA) vector that appears to fulfil these criteria. This pDNA vector combines a scaffold/matrix attachment region (S/MAR) with a human liver-specific promoter (alpha1-antitrypsin (AAT)) in such a way that long-term expression is enabled in murine liver following hydrodynamic injection. Long-term expression is demonstrated by monitoring the longitudinal luciferase expression profile for up to 6 months by means of in situ bioluminescent imaging. All relevant control pDNA constructs expressing luciferas…

Optimizing Liver Division Technique for Procuring Left Lateral Segment Grafts: New Anatomical Insights.

2021

Left liver lobe (left lateral segment) grafts (LLG) is currently the most commonly used graft to transplant children (2/3 of cases currently in Europe); it is prepared by liver division (DL) in both living (LD) and deceased donors (DD) settings. Technically speaking, classical DL is through the parenchyma of segment IV - dividing the main left glissonean pedicle left to the main biliary confluence (trans-hilar (TH) approach): historically, this technique was introduced by Bismuth and Pichlmayr in 1988 in DD setting, and applied one year later for the first successful living donor transplantations by Strong (Figure 1).

Risk of Virus Contamination Through Surgical Smoke During Minimally Invasive Surgery: A Systematic Review of the Literature on a Neglected Issue Revi…

2020

Abstract Context The coronavirus disease 2019 (COVID-19) pandemic raised concerns about the safety of laparoscopy due to the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diffusion in surgical smoke. Although no case of SARS-CoV-2 contagion related to surgical smoke has been reported, several international surgical societies recommended caution or even discouraged the use of a laparoscopic approach. Objective To evaluate the risk of virus spread due to surgical smoke during surgical procedures. Evidence acquisition We searched PubMed and Scopus for eligible studies, including clinical and preclinical studies assessing the presence of any virus in the surgical smoke fr…

Laparoscopic treatment of a large pedunculated hemangioma of the liver: a case report

2016

Hepatic hemangiomas are the most common benign tumors of the liver, often asymptomatic and discovered incidentally. A 62-year-old woman was referred to our Institution under the suspicion of having an 8 cm-sized GIST. Due to the atypical features of the lesion on TC scan, a biopsy was performed. We report the case of pedunculated hepatic hemangioma with the aim to discuss the diagnostic approach, the possible causes of misdiagnosis and the opportunity of the laparoscopic approach.
