What complications can be induced by advanced esophageal cancer?
1, transferred to other organs
When esophageal cancer develops to the advanced stage, cancer cells can metastasize to important organs, such as lung, liver and brain, causing liver ascites, dyspnea, jaundice and coma. If it occurs in esophageal-tracheal fistula, cancer cells metastasize to supraclavicular lymph nodes or other organs, cachexia, etc. Are symptoms of advanced esophageal cancer. If cancer cells invade the recurrent laryngeal nerve, it will lead to hoarseness and vocal cord paralysis. If cancer cells oppress or invade tracheobronchitis, it will cause irritating dry cough. If it invades the phrenic nerve, it will cause phrenic paralysis. If the vagus nerve is invaded, the heart rate will increase. If the brachial plexus nerve is invaded, it will lead to numbness, pain and abnormal sensation in the arm. If it is compressed to the superior vena cava, it may lead to superior vena cava compression syndrome.
2. Cachexia
When esophageal cancer develops to the advanced stage, the symptoms of dysphagia will become more and more obvious, and weight loss and negative nitrogen balance will occur due to long-term hunger, which will increase the incidence and mortality of postoperative complications. When esophageal cancer appears cachexia or obvious dehydration, the main symptoms are emaciation, fatigue, loose and dry skin, mainly manifested as fatigue.
3, bleeding or hematemesis
Most esophageal cancers are accompanied by vomiting, especially when cancer cells invade large blood vessels, vomiting blood and occasional massive bleeding will occur.
4, esophageal cancer perforation
Perforation of esophageal cancer is the main complication of esophageal cancer. When esophageal cancer develops to the advanced stage, especially ulcerative esophageal cancer, it can be caused by local erosion and severe ulceration of cancer cells. The symptoms of different puncture locations and adjacent organs are also very different. If it penetrates the trachea, it will lead to esophagotracheal fistula, induce esophageal active veins, and even die of massive bleeding. Pay attention to diet and recuperation in the late stage of esophageal cancer. If cachexia occurs, protein should be supplemented reasonably, which can be obtained from milk, eggs, lean meat and various vegetables. If there is complete obstruction, intravenous rehydration or gastrostomy should be taken to provide nutritious food to maintain life. Avoid eating cold food and food that has been left for too long, and supplement nutrients reasonably. Avoid smoking, drinking and drinking coffee. Face the disease correctly and eliminate bad emotions in time.
