Analysis of the causes of esophageal obstruction

There are various human diseases, especially those related to the digestive system, which make people feel uncomfortable or have a great impact on daily life. For example, stomach problems have many dietary taboos. If they are very serious, even every meal of the day will be a problem. For a foodie, it is a life worse than death. Here are the reasons why the esophagus is blocked. I hope it will be helpful to people with these symptoms.

There are many types of benign tumors of the esophagus. Leiomyoma is the most common benign esophageal tumor and may be multiple, but most patients have a good prognosis. The most common esophageal malignancy is squamous cell carcinoma, followed by adenocarcinoma. Other esophageal malignancies include lymphoma, leiomyosarcoma, and metastatic carcinoma. The following takes esophageal cancer as an example.

Early esophageal cancer may have no symptoms. When the esophageal lumen is narrowed to < 14 mm, the most common symptom is dysphagia (difficulty swallowing or a sensation of obstruction as food moves down the esophagus); patients first have difficulty swallowing solid foods, then semisolid foods, and finally liquid foods and saliva; the progression of these stages suggests a progressive malignant process rather than spasmodic, benign, or peptic strictures. Chest pain often radiates to the back.

Even if the patient has a normal appetite, weight loss is almost always present. Compression of the recurrent laryngeal nerve can cause vocal cord paralysis and hoarseness. Compression of the sympathetic nerves can cause Horner's syndrome, and compression of nerves in other parts of the body can also cause spinal pain, hiccups, and diaphragmatic paralysis. Malignant pleural effusions and pulmonary metastases can cause dyspnea. Intraluminal tumors may cause odynophagia, vomiting, hematemesis, melena, iron deficiency anemia, pulmonary aspiration, cough, lung abscess, and pneumonia. Other symptoms include superior vena cava syndrome, malignant ascites, and bone pain.

Because the lymph of the entire esophagus is drained by the lymphatic plexus, lesions of the internal venous lymphatics, cervical lymphatics, supraclavicular lymphatics, diaphragmatic lymphatics and abdominal lymphatics may occur. The tumor often metastasizes to the lungs and liver and may even metastasize to distant sites (eg, bones, heart, brain, adrenal glands, kidneys, peritoneum).

The above is an analysis of the causes of esophageal blockage. It can be seen that it may be diseases such as esophageal cancer, which should be given enough attention and timely treatment to avoid other complications and regret. People are sometimes strong, but sometimes fragile, especially when they are sick. Therefore, if there is any discomfort in the body, we should pay enough attention to it and not be careless, otherwise, we will regret it.
