Impact of COVID-19 on pre-existing liver disease.

Patients with chronic liver disease of any etiology who become infected with SARS-CoV-2 have been found to have a higher risk of mortality compared to those patients who do not have chronic liver disease. A literature review was conducted in the relationship between COVID 19 and preexistence of liver disease. The proportion of COVID-19 patients with abnormal liver function on admission ranged from 40 % to 75 % and the proportion with liver injury was close to 30%.

Fenotipos de la enfermedad por reflujo gastroesofágico: una visión basada en su fisiopatología.

The advancement of knowledge in pathophysiology and underlying etiologies of gastroesophageal reflux disease (GERD) has allowed the development of the concept of disease beyond the acidity of reflux. The variability in the symptom presentation and the response to treatment cannot be attributed only to reflux composition, since esophageal factors, such as structural, mechanical, biochemical, and physiological aspects, play an important role. The proposed personalized approach to GERD uses a stepwise approach that optimizes performance and phenotypic outcome while minimizing invasiveness, risk, and cost.

El daño colateral de la atención de la pandemia de COVID-19.

Throughout history, pandemics have had a major impact on humanity. The measures used to combat them cause collateral damage. During the COVID-19 pandemic, the actions taken to reduce the exposure, the number of infections, and the case fatality rate focus on reducing mortality, however, the collapse of the health system can cause an even greater number of deaths.

Recomendaciones para procedimientos quirúrgicos durante la pandemia de COVID-19 (SARS-CoV-2). Liderazgo hacia el retorno a lo electivo.

In late December 2019, COVID-19, a new emerging disease, quickly spread in Wuhan, China. The WHO formally declared it a pandemic and a health emergency on March 11, 2020. The objective of this article is to specify and list key points in relation to the recommendations issued by the different colleges, and global surgical societies, for the benefit of the Mexican medical and surgical community.

Evaluation of the satisfaction of the patient undergoing screening colonoscopy and quality of the procedure.

Background: Screening colonoscopy requires quality parameters to determine its efficacy to detect cancerous or precancerous lesions. Limitations of the procedure are the patient's rejection, difficulty for its preparation or lack of preparation.

Objective: To assess whether patient satisfaction correlates with the quality of the procedure.

The Mexican consensus on alcoholic hepatitis.

Alcoholic hepatitis is a frequent condition in the Mexican population. It is characterized by acute-on-chronic liver failure, important systemic inflammatory response, and multiple organ failure. The severe variant of the disease implies elevated mortality.

Acute dysphagia presentation and its association with esophagitis dissecans and concomitant diseases. A diagnostic challenge.

Esophagitis dissecans (ESD) is an uncommon disease that is associated with eosinophilic esophagitis (EoE), candidiasis and/or drugs. We aim to characterize the clinical, endoscopic and histological damage of the mucosal in subjects with dysphagia, its relation to concomitant entities and the treatment response. This is a retrospective observational study in patients with dysphagia and esophageal mucosal damage We included 23 patients (mean age = 55 years) who had GERD symptoms, dysphagia and/or odynophagia.

In search of the grail: A race for acid suppression.

Proton pump inhibitors are the reference standards for the treatment of acid-related diseases. Acid suppression in gastroesophageal reflux disease is associated with a high rate of mucosal cicatrization, but symptom response differs among endoscopic phenotypes. Extraesophageal manifestations have a good clinical response in patients that present with abnormal acid exposure (diagnostic test) in the esophagus.

Primary Prophylaxis to Prevent the Development of Hepatic Encephalopathy in Cirrhotic Patients with Acute Variceal Bleeding.

Background And Aim: Variceal bleeding is the second most important precipitating factor related to the development of episodic hepatic encephalopathy; but to date there are no recommendations to prevent this complication. The aim of this study was to compare if primary prophylaxis with lactulose or L-ornithine L-aspartate or rifaximin, in cirrhotic patients with variceal bleeding, is better than placebo for avoiding the development of hepatic encephalopathy.

Methods: A randomized, double-blind, placebo-controlled clinical trial (ClinicalTrials.

The fourth Mexican consensus on Helicobacter pylori.

Important advances have been made since the last Mexican consensus on the diagnosis and treatment of Helicobacter pylori (H. pylori) infection was published in 2007. Therefore, the Asociación Mexicana de Gastroenterología summoned 20 experts to produce "The Fourth Mexican Consensus on Helicobacter pylori".

Efficacy of narrow-band imaging for detecting intestinal metaplasia in adult patients with symptoms of dyspepsia.

Introduction And Objective: Atrophy and intestinal metaplasia are early phenotypic markers in gastric carcinogenesis. White light endoscopy does not allow direct biopsy of intestinal metaplasia due to a lack of contrast of the mucosa. Narrow-band imaging is known to enhance the visibility of intestinal metaplasia, to reduce sampling error, and to increase the diagnostic yield of endoscopy for intestinal metaplasia in Asian patients.

Metadoxine improves the three- and six-month survival rates in patients with severe alcoholic hepatitis.
