The Rationale for Combining Normothermic Liver Machine Perfusion with Continuous Renal Replacement Therapy to Maintain Physiological Perfusate during Ex Vivo Organ Perfusion.

The possibility of keeping liver grafts viable and functioning until transplantation has been explored since the 1950s. However, the current modalities of Normothermic Machine Perfusion (NMP) have shown several limitations, such as the inability to correct electrolytes and pH derangements efficiently. Combining NMP with continuous kidney replacement therapy (CKRT) might provide a promising new model to overcome these issues.

Advocating for a "shift-to-left" in transplant oncology: left grafts, RAPID and dual graft.

The extension of liver transplantation to new oncologic indications might exacerbate the shortage of grafts. Living donor liver transplantation (LDLT) may emerge as a viable resource, although its diffusion in the Western world is still very limited. Several groups have advocated for minimizing the impact on donors by reducing the extent of donor hepatectomy, i.

Textbook Outcome of Laparoscopic Microwave Ablation for Hepatocellular Carcinoma.

In the context of spreading interest in textbook outcome (TO) evaluation in different fields, we aimed to investigate an uncharted procedure, that is, laparoscopic microwave ablation (MWA) for hepatocellular carcinoma (HCC). Absence of post-MWA complications, a hospital stay of three days, no mortality nor readmission within 30 days, and complete response of the target lesion at post-MWA CT scan defined TO achievement. Patients treated between January 2014 and March 2021 were retrospectively reviewed, and of the 521 patients eligible for the study, 337 (64.

Colon Rectal Liver Metastases: The Role of the Liver Transplantation in the Era of the Transplant Oncology and Precision Medicine.

The development of liver metastases in colon rectal cancer has a strong impact on the overall survival (OS) of the patient, with a 5-year survival rate of 5% with palliative treatment. Surgical resection combined with pharmacological treatment can achieve a 5-year OS rate of 31-58%. However, in only 20% of patients with colon rectal liver metastases (CRLMs), liver resection is feasible.

Sustained Complete Response after Biological Downstaging in Patients with Hepatocellular Carcinoma: XXL-Like Prioritization for Liver Transplantation or "Wait and See" Strategy?

The XXL trial represents the first prospective validation of "biological downstaging" in liver transplantation (LT) for hepatocellular carcinoma. The aim of this study was to compare the Padua downstaging protocol to the XXL protocol in terms of downstaging failure rates and patient outcome. A total of 191 patients undergoing aggressive surgical downstaging and potentially eligible for LT from 2012 to 2018 at our center were retrospectively selected according to XXL trial criteria.

Thoracoscopic Ablation of Critically Located Liver Tumors: A Safety and Efficacy Cohort Study.

Liver resection represents the first curative treatment to treat primary and secondary hepatic tumors. Thoracoscopic liver ablation is a viable and minimally invasive alternative treatment, especially for patients with previous multiple abdominal surgeries. The aim of the study was to evaluate the safety and efficacy of thoracoscopic ablation for liver tumors.

Bile Microbiota in Liver Transplantation: Proof of Concept Using Gene Amplification in a Heterogeneous Clinical Scenario.

Historically, bile in the biliary tract has been considered sterile. Most of the series are based on patients with biliary tract diseases or the bile has been obtained with procedures susceptible to contamination. We evaluated the bile in a heterogeneous cohort of liver donors and recipient patients, with samples obtained in a sterile way, directly from the gallbladder and the common bile duct.

Human Small Intestine Transplantation: Segmental Susceptibility to Ischemia Using Different Preservation Solutions and Conditions.

Background And Aims: Among all transplanted abdominal organs, the small intestine is one of the most ischemia sensitive. Appropriate graft selection, procurement, and preservation are crucial for optimum graft and patient survival. We evaluated ischemic damage in human small intestine grafts under different hypothermic preservation conditions (cold static and continuous perfusion) and solutions: histidine-tryptophan-ketoglutarate (HTK) and University of Wisconsin (UW).

Sorafenib treatment has the potential to downstage advanced hepatocellular carcinoma before liver resection.

Sorafenib is acknowledged as the standard therapy for advanced hepatocellular carcinoma (HCC) but in the clinical practice the treatment of these patients is extremely complex and needs to be personalized. New evidence suggests that surgical resection-based multimodal treatments may improve outcome in these patients. There is no strong evidence supporting the ability of sorafenib in downstage HCC before surgery.

Videolaparoscopic microwave ablation in patients with HCC at a European high-volume center: Results of 815 procedures.

Background: Videolaparoscopic (VL) microwave ablation (MWA) is not included in most of the international guidelines as a therapeutic option for hepatocellular carcinoma (HCC). Aim of this study was to assess the safety of VL MWA in patients with HCC for whom resection or percutaneous ablation is unsuitable.

Methods: A retrospective analysis was performed on a prospective database of patients with HCC treated with VL MWA at our institution from 2009 to 2016.

Very Early Introduction of Everolimus in De Novo Liver Transplantation: Results of a Multicenter, Prospective, Randomized Trial.

Early everolimus (EVR) introduction and tacrolimus (TAC) minimization after liver transplantation may represent a novel immunosuppressant approach. This phase 2, multicenter, randomized, open-label trial evaluated the safety and efficacy of early EVR initiation. Patients treated with corticosteroids, TAC, and basiliximab were randomized (2:1) to receive EVR (1.

Resection for hepatocellular cancer: overpassing old barriers.

Several recent studies have shown that the selection limits commonly used for patients with hepatocellular cancer (HCC) potentially requiring a liver resection (LR) are too restrictive. The present review aims at investigating the studies showing that LR is no longer a treatment suitable only for highly selected patients, but also for patients selectively presenting one-to-more negative factors. Several specific variables have been investigated, none of them showing to be an absolute contraindication for LR: age; single vs.

Microwave Thermal Ablation in an Unusual Case of Malignant and Locally Advanced Rare Tumor of Pancreas in ASA IV Old Male Patient and Literature Review.

Pancreatic intraductal papillary-mucinous neoplasm is a rare primary neoplasm of unknown pathogenesis. This kind of tumor represents 0.2-2.

Extraordinary disease-free survival in a rare malignant extrarenal rhabdoid tumor: a case report and review of the literature.

Background: Malignant extrarenal rhabdoid tumor of the gastrointestinal tract is rarely reported in the literature. It is characterized by poor prognosis and aggressive metastatic features. A literature review evidenced only 19 cases, with poor outcome.

Modulation of Intestinal Microbiome Prevents Intestinal Ischemic Injury.

Butyrate protects against ischemic injury to the small intestine by reducing inflammation and maintaining the structure of the intestinal barrier, but is expensive, short-lived, and cannot be administered easily due to its odor. Lactate, both economical and more palatable, can be converted into butyrate by the intestinal microbiome. This study aimed to assess in a rat model whether lactate perfusion can also protect against intestinal ischemia.

Liver radiofrequency ablation as emergency treatment for a ruptured hepatocellular carcinoma: a case report.

Background: Hemoperitoneum is a possible complication of hepatocellular carcinoma that may require emergency surgery as an alternative to radiological locoregional therapies.

Case Presentation: We present a case report of a 78-year-old white man with alcoholic-related cirrhosis and a multifocal hepatocellular carcinoma. An abdominal computed tomography scan showed multiple and bilateral foci of bleeding from broken liver cancer.

Model for end-stage liver disease-sodium and survival benefit in liver transplantation.

There are currently no studies calculating the survival benefit of liver transplantation (LT) according to model for end-stage liver disease-sodium (MELD-Na) and based on the competing risk (CR) method. We enrolled consecutive adult patients with chronic end-stage liver disease entering the waiting list (WL) for primary LT (WL group = 337) and undergoing LT (LT group = 220) in the period 2006-2009. Two independent multivariable regressions (WL and LT models) were created to measure the prognostic power of MELD-Na with respect to MELD.

Use of N-acetylcysteine during liver procurement: a prospective randomized controlled study.

Antioxidant agents have the potential to reduce ischemia/reperfusion damage to organs for liver transplantation (LT). In this prospective, randomized study, we tested the impact of an infusion of N-acetylcysteine (NAC) during liver procurement on post-LT outcomes. Between December 2006 and July 2009, 140 grafts were transplanted into adult candidates with chronic liver disease who were listed for first LT, and according to a sequential, closed-envelope, single-blinded procedure, these patients were randomly assigned in a 1/1 ratio to an NAC protocol (69 patients) or to the standard protocol without NAC [71 patients (the control group)].
