[Portal vein embolization prior to major hepatectomy: A multidisciplinary approach for advanced liver tumors in Chile].

Background: One of the main limitations to achieving a complete tumor resection in patients with technically resectable liver tumors is the presence of a small future liver remnant (FLR). Portal vein embolization (PVE) allows hypertrophy of the non-embolized lobe, reducing the risk of postoperative liver failure.

Aim: To describe the experience of portal embolization prior to hepatectomy and its effectiveness in converting advanced unresectable liver tumors into resectable tumors.

Risk factors for readmission after a cholecystectomy: a case-control study.

Objective: The aim of this study was to assess the risk factors associated with 30-day hospital readmissions after a cholecystectomy.

Methods: We conducted a case-control study, with data obtained from UC-Christus from Santiago, Chile. All patients who underwent a cholecystectomy between January 2015 and December 2019 were included in the study.

[Outcomes of Laparoscopic Liver Resection for Hepatocellular Carcinoma: A Single-Center Experience].

Background: Hepatocellular carcinoma (HCC) is the sixth most common cancer in the world. Surgery is the treatment of choice in stages 0 and A in the Barcelona Clinic Liver Cancer classification. A minimally invasive technique in this scenario has the advantage of reducing postoperative pain, blood loss, and hospital stay.

Liver resection for hepatolithiasis: A multicenter experience in Latin America.

Background: Hepatolithiasis is a prevalent disease in Asia but rare in Western countries. An increasing number of cases have been reported in Latin America. Liver resection has been proposed as a definitive treatment for complete stone clearance.

Right Lobe Liver Donation After Bariatric Surgery. A Case Series of 4 Living Donors.

Background: The increasing prevalence of obesity and need for bariatric surgery as well as the expanding use of living donors for liver transplantation means that potential donors could present with this surgical history. We present 4 cases of liver donors with previous bariatric surgery in our living donor liver transplant program.

Methods: A retrospective descriptive analysis of patients with a bariatric surgery history who underwent right hepatectomy in our living donor liver transplant program is presented.

[Liver transplantation for non-resectable colorectal liver metastases: A review].

In Chile, colorectal cancer ranks third in incidence and fifth in mortality. Half of these patients have liver metastases at the diagnosis, and only 30% of them are resectable. Despite the development of many complex hepatobiliary procedures to achieve the total resection of metastases, the long-term survival with these techniques is not good.

Immediate antiinflammatory effects of inhaled budesonide in patients with asthma.

Background: In patients with asthma, single doses of inhaled glucocorticosteroids (ICS) have been reported to have antiinflammatory actions that can be detected several hours after drug administration. However, the onset and duration of the effect have not been investigated. We therefore measured airway blood flow ([Formula: see text]aw) as an index of airway inflammation to determine the time course and dose dependence of the antiinflammatory action of an ICS in 20 patients with moderate asthma receiving regular ICS treatment.

Airway vascular endothelial function in healthy smokers without systemic endothelial dysfunction.

Background: Cigarette smoking can lead to systemic endothelial dysfunction. Since the airway circulation is exposed to a high concentration of cigarette smoke constituents, we reasoned that airway vascular endothelial dysfunction could be present in healthy smokers without systemic endothelial dysfunction.

Objectives: The purpose of this study was to compare airway and systemic endothelial function and measure markers of systemic inflammation in lung-healthy current smokers.

Acute effects of salmeterol and fluticasone propionate alone and in combination on airway blood flow in patients with asthma.

Background: The airway contains airway smooth muscle and airway vascular smooth muscle. The acute effects of inhaled long-acting β(2)-adrenergic agonists (LABAs) alone, or in combination with an inhaled glucocorticoid (ICS), on airway smooth muscle tone in asthma are known; however, to the best of our knowledge, their effect on airway vascular smooth muscle tone has not been investigated previously. The objective of this study was to investigate the immediate effects of a LABA and an ICS alone and in combination on airway blood flow (Qaw) as an index of airway vascular smooth muscle tone in patients with stable asthma.

Effect of an inhaled glucocorticoid on endothelial function in healthy smokers.

Cigarette smoking is associated with attenuated endothelium-dependent vasodilation (endothelial dysfunction) in the systemic circulation, including the airway circulation. We wished to determine whether an inhaled corticosteroid could restore endothelial function in the airway of lung-healthy current smokers, ex-smokers, and nonsmokers. We measured baseline airway blood flow (Qaw) and Qaw reactivity to inhaled albuterol as an index of endothelium-dependent vasodilation and to sublingual nitroglycerin as an index of endothelium-independent vasodilation in lung-healthy current smokers, ex-smokers, and nonsmokers.
