    Abstract

    Insights

    This study analyzed esophageal stent adverse events, finding gastrointestinal bleeding and chest pain as common issues. Improving safety requires better regulations and monitoring systems for esophageal stent use.

    Area of Science:

    • Medical Device Safety
    • Gastroenterology
    • Clinical Research

    Background:

    • Esophageal stents are crucial for treating various conditions.
    • Understanding adverse drug reactions (ADR) and medical device reports (MDR) is vital for patient safety.

    Purpose of the Study:

    • To investigate the characteristics and contributing factors of adverse events associated with esophageal stents.
    • To propose strategies for enhancing the safe use of esophageal stents.

    Main Methods:

    • Retrospective analysis of 153 MDR cases from the FDA MAUDE database (2012-2015).
    • Screening and analysis of 96 valid documents from the CNKI database (1994-2015).

    Main Results:

    • Common adverse events include gastrointestinal bleeding, chest pain, and foreign body sensation.
    • Risks are associated with the inherent product characteristics and usage during medical procedures.

    Conclusions:

    • Enhancing public safety necessitates perfecting related laws and regulations.
    • Establishing a robust MDR monitoring system and strengthening responsibilities among authorities, manufacturers, suppliers, and medical institutions are crucial.

    Esophageal Varices-I: Introduction01:24

    Esophageal Varices-I: Introduction

    Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

    Local Anesthetics: Adverse Effects01:12

    Local Anesthetics: Adverse Effects

    While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
    Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

    Inhaled Medications

    Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...

    Esophageal Perforation-I: Introduction01:22

    Esophageal Perforation-I: Introduction

    Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
    The location of esophageal perforation can vary, occurring anywhere along the esophagus....

    Esophageal Strictures-I: Introduction01:30

    Esophageal Strictures-I: Introduction

    Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
    Etiology
    The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

    Integration of Synaptic Events01:28

    Integration of Synaptic Events

    Synaptic integration mainly includes the summation of graded potentials. Graded potentials, regardless of their type, cause subtle alterations in membrane voltage, resulting in either depolarization or hyperpolarization. These incremental changes, when combined or summed, can propel the neuron toward its threshold. Consider, for example, a membrane experiencing a +15 mV shift, causing it to depolarize from -70 mV to -55 mV. In this scenario, graded potentials govern the membrane's ability to...
