Graft Survival in Liver Transplantation: An Artificial Neuronal Network Assisted Analysis of the Importance of Comorbidities.

Objectives: Liver transplant represents a widespread therapeutic option for patients with end-stage liver failure. Up to now, most of the scores describing the probability of liver graft survival have shown poor predictive performance. With this in mind, the present study seeks to analyze the predictive value of recipient comorbidities on liver graft survival within the first year.

Analysis of survival and clinicopathological characteristics in patients after liver resection for colorectal liver metastases according to resection margin.

Background: Criteria for resectability of colorectal liver metastases (CRLM) have been expanded over the last decade along with the improvement in chemotherapy.

Objective: Analyze the differences in several clinicopathological characteristics and overall survival (OS) between patients who underwent an R0 (tumour margin > 1 mm) or R1 (margin < 1 mm) resection.

Method: Retrospective study including 144 patients with CRLM who underwent a potentially curative liver surgery between 2010 and 2018.

Biliary growth of colorectal liver metastasis: case report and review of the literature.

Introduction: Intrabiliary growth of colorectal liver metastasis determines their capability of dissemination and relapse.

Case Report: 65-year-old woman underwent sigmoidectomy (2011) and left hepatectomy due to liver metastases affecting the bile tract (2014). In 2020 she developed a 2cm tumour in the union of both hepatic ducts.

Effect of Melatonin as an Antioxidant Drug to Reverse Hepatic Steatosis: Experimental Model.

Introduction: The hepatic steatosis of the nonalcoholic origin or NAFLD is increasing at present, particularly in Western countries, parallel to the increase in obesity, constituting one of the most prevalent hepatic processes in the Western society. Melatonin has been successfully tested in experimental models in mice as a drug capable of reversing steatosis. The effect of melatonin on fat metabolism can be summarized as a decrease in lipid peroxidation and a decrease in oxidative stress, biochemical phenomena intimately related to fat deposition in the hepatocyte.

[Postoperative intra-abdominal foreign body resemblance to neoplasm. Report of a case and review of the bibliography].

Introduction: Gossypibomas or textilomas are materials remain in the abdomen after surgery. It is very difficult to assess its impact due to medico-legal implications, hence the interest in the publication of this type of pathology.

Clinical Case: Women of 76 years who had undergone a hysterectomy and double anexectomy 6 months before admission to our hospital, apparently without perioperative complications.
