Involvement of β-catenin expression in hepatocellular carcinoma prognosis in a cohort of patients undergoing curative treatment.

Background: Hepatocellular carcinoma is a tumor of epithelial origin that arises from the action of different carcinogens on the hepatocytes and has a high worldwide incidence. The prognostic markers of this disease have not been completely established. Mutations in the gene encoding β-catenin are overexpressed in hepatocellular carcinoma.

Textbook outcome in the surgical treatment of liver hydatid cyst.

Background: Textbook outcome is a composite measure used in surgery to define the ideal postoperative period and to assess the quality of care. The aim of this study was to analyze the incidence of textbook outcome and the factors independently associated with its achievement following surgical treatment of liver hydatid cysts.

Methods: Retrospective cohort study of patients operated on for liver hydatid cysts between January 2006 and December 2021.

Resection of isolated pancreatic metastases from pulmonary neoplasia: a systematic review.

Several types of cancers have been reported to metastasize to the pancreas. Lung cancer with isolated pancreatic metastasis is extremely rare. In selected patients, surgery is advocated.

Influence of the tumor site and histopathology after resection for non-colorectal non-neuroendocrine liver metastases. A single center experience.

Introduction: It remains unclear whether liver resection is justified in patients with non-colorectal non-neuroendocrine liver metastases (NCNNLM). A single-center study was conducted to analyse overall survival (OS), disease-free survival (DFS), and potential prognostic factors in patients with different types of NCNNLM.

Method: A retrospective analysis of all patients who underwent liver resection of NCNNLM from January 2006 to July 2019 was performed.

Surgical treatment of liver hydatid cyst in elderly patients: A propensity score-matching retrospective cohort study.

Background: Cystic echinococcosis is a clinically complex chronic parasitic disease and a major socioeconomic problem in endemic areas. The safety of liver resection in elderly patients is often debated among medical professionals. We analyzed the postoperative morbidity and mortality rates of elderly patients who underwent surgery at our unit.

Adenosquamous cancer of the pancreas: A multicenter retrospective study.

Introduction: Adenosquamous cancer of the pancreas (ASCP) is an aggressive, infrequent subtype of pancreatic cancer that combines a glandular and squamous component and is associated with poor survival.

Methods: Multicenter retrospective observational study carried out at three Spanish hospitals. The study period was: January 2010-August 2020.

Implementation of a regional reference center in pancreatic surgery. Experience after 631 procedures.

Introduction: The main objective of this study is to determine whether our unit meets the quality standards required by the scientific community from the reference centers for pancreatic surgery in terms of peri-operative results. The secondary objectives are to compare the different pancreatic surgery techniques performed in terms of early post-operative morbidity and mortality and to analyze the impact of the resections added in these terms.

Method: Descriptive, retrospective and single-center study, corresponding to the period 2006-2019.

Pancreatic metastases from renal cell carcinoma. Postoperative outcome after surgical treatment in a Spanish multicenter study (PANMEKID).

Background: Renal Cell Carcinoma (RCC) occasionally spreads to the pancreas. The purpose of our study is to evaluate the short and long-term results of a multicenter series in order to determine the effect of surgical treatment on the prognosis of these patients.

Methods: Multicenter retrospective study of patients undergoing surgery for RCC pancreatic metastases, from January 2010 to May 2020.

Melatonin Induces Apoptosis and Modulates Cyclin Expression and MAPK Phosphorylation in Pancreatic Stellate Cells Subjected to Hypoxia.

In certain diseases of the pancreas, pancreatic stellate cells form an important part of fibrosis and are critical for the development of cancer cells. A hypoxic condition develops within the tumor, to which pancreatic stellate cells adapt and are able to proliferate. The consequence is the growth of the tumor.

Melatonin Modulates the Antioxidant Defenses and the Expression of Proinflammatory Mediators in Pancreatic Stellate Cells Subjected to Hypoxia.

Pancreatic stellate cells (PSC) play a major role in the formation of fibrotic tissue in pancreatic tumors. On its side, melatonin is a putative therapeutic agent for pancreatic cancer and inflammation. In this work, the actions of melatonin on PSC subjected to hypoxia were evaluated.

Prospective Study Correlating External Biliary Stenting and Pancreatic Fistula Following Pancreaticoduodenectomy.

Background: Postoperative pancreatic fistula (POPF) is the most common complication of pancreaticoduodenectomy (PD). Sometimes POPF is associated with biliary fistula (BF) or "mixed" fistula. The purpose of this study is to assess whether the severity of the fistulae, when present, is decreased with an external biliary stent in place.

Jaundice as a clinical presentation in liver hydatidosis increases the risk of postoperative biliary fistula.

Purpose: Echinococcosis, also known as hydatidosis, is a zoonosis that is endemic in many countries worldwide. Liver hydatid cysts have a wide variety of clinical manifestations, among which obstructive jaundice is one of the rarer forms. The aims of the study were to analyze the preoperative management of these patients and to record the kind of surgical treatment performed and the short- and long-term postoperative results.

Implementation of a regional reference center in pancreatic surgery. Experience after 631 procedures.

Introduction: The main objective of this study is to determine if our unit meets the quality standards required by the scientific community from the reference centers for pancreatic surgery in terms of peri-operative results. The secondary objectives are to compare the different pancreatic surgery techniques performed in terms of early post-operative morbidity and mortality and to analyze the impact of the resections added in these terms.

Method: Descriptive, retrospective and single-center study, corresponding to the period 2006-2019.

Side-to-side duodenojejunostomy after resection of third and fourth duodenal portions with pancreatic preservation.

Infra-ampullary duodenal lesions are rare and surgical management is controversial. Reconstruction after resection is usually performed by end-to-end or end-to-side duodenojejunostomy. The goal was to analyze our experience, perioperative management, and results after side-to-side duodenojejunostomy.

Melatonin modulates red-ox state and decreases viability of rat pancreatic stellate cells.

In this work we have studied the effects of pharmacological concentrations of melatonin (1 µM-1 mM) on pancreatic stellate cells (PSC). Cell viability was analyzed by AlamarBlue test. Production of reactive oxygen species (ROS) was monitored following CM-HDCFDA and MitoSOX Red-derived fluorescence.

Pancreatic resection for metastatic renal cell carcinoma. A systematic review.

Background: Renal cell carcinoma (RCC) can lead to secondary pancreatic tumors even years after nephrectomy was performed. Surgical resection in selected patients shows appropriate survival rates.

Methods: A systematic review was performed following PRISMA guidelines.

Postoperative bleeding and biliary leak after liver resection: A cohort study between two different fibrin sealant patches.

Different topical products have been tested in liver resection to get a control of bleeding. This study compares the effectiveness and complications between two haemostatic agents Tachosil versus Hemopatch. A cohort study including patients who underwent liver resection since November 2014 to April 2016 was conducted.

Pattern of Relapse in Hepatic Hydatidosis: Analysis of 238 Cases in a Single Hospital.

Introduction: Hydatidosis is a chronic disease that is endemic and prevalent in certain regions of the world. Surgical treatment is the best option, although its main problem is that there is a high rate of recurrence. The objective of the present study was to assess its therapeutic management and the factors related to its postoperative morbidity and relapse.
