Closure of the esophagus

Closing the appetite vein or **Left Gastric Artery Embolization** is one of the newest methods of appetite control, which helps to lose weight by reducing the release of the hunger hormone (ghrelin). This method is less invasive than other bariatric surgery methods, but like any other method, it has its own advantages and disadvantages. In this article, we will comprehensively examine **closing the appetite vein** and analyze all its aspects. **What is the closure of the appetite vessel?** Occluding the oesophageal vein means blocking the left gastric artery, which supplies blood to a part of the stomach called the fundus. The fundus of the stomach is the main part of ghrelin hormone production. Decreased blood supply to this area decreases the production of ghrelin hormone and thus decreases appetite. This method was first used to control gastrointestinal bleeding, but due to its effect on reducing appetite, special attention has been paid to it. ### **How to close the appetite vein** This procedure is performed on an outpatient basis under local anesthesia. The steps to do it are: 1. **Patient preparation:** The patient does not need anesthesia and the initial preparation includes disinfection of the injection site and the use of local anesthesia. 2. Access to the left gastric artery: Through angiography, the doctor reaches the left gastric artery by inserting a catheter from the femoral artery (in the thigh area). 3. **Injection of blocking substance:** A special substance is injected into the artery to create a clot that reduces blood flow to the fundus of the stomach. 4. **End of the process:** After ensuring that the artery is blocked, the catheter is removed and the patient is monitored.
