Esophageal tumor is a disease with high incidence rate in China, the death rate is located in the top 5 malignant tumors, and the high incidence areas are North China, North Jiangsu Province, East Zhejiang Province, Fujian and Gan Province, and Chaoshan and Meizhou areas in Guangdong Province. According to the introduction of Shanghai Yuanda Cardiothoracic Hospital, patients basically do not have any discomfort in the early stage of esophageal tumor. As the condition develops and the scope of the tumor expands, the patient may gradually have abnormal sensation. At the beginning, it is not easy for patients to pay attention to this feeling because it doesn’t affect their life and living, but once the patients realize that they have difficulty in swallowing, most of them have already been in the middle or late stage of the tumor. Etiology Wang Qiang, Director of Shanghai Yuanda Cardiothoracic Hospital, introduced that the etiology of esophageal tumors is still unclear, mainly some factors that increase the damage to the esophagus can cause esophageal tumors. In Guangdong Chaoshan area, many people love to drink Kung Fu tea, which is very hot, but they have to drink it in one gulp, and the mucous membrane of the esophagus will be easily scalded. If they keep drinking it, the mucous membrane of esophagus will be easily burned. If they keep drinking it, the mucous membrane will be burned again without recovering, which will cause ulcers and may lead to neoplasm. Some regions love to eat pickled food or kimchi sauerkraut, these foods contain a large number of nitrosamine compounds, is also the main cause of tumors. Symptoms: Modern people live a stressful life, often swallow their food, and often think that they eat too fast and do not care about the discomfort of swallowing. At the same time, due to air pollution and work tension, there are many people suffering from chronic pharyngitis, which is easier to ignore the discomfort of the pharynx. According to the census data, the following points may be the early symptoms of esophageal tumor: 1. Distension or slight pain behind the sternum. This symptom does not occur continuously, but is intermittent or aggravated after exertion and when eating quickly. This is because the esophagus itself is peristaltic at any time, and the symptom will appear only when it peristalsis to the lesion site. 2.Foreign body sensation when swallowing food. During swallowing, food (especially dry and hard food) passing through the lesion area may produce a foreign body sensation, which is often fixed in one part, and some patients describe the sensation like having never finished swallowing something. Because the symptoms are mild and intermittent, it is easy for patients to neglect. 3, swallowing stagnation. That is, the patient swallowing food seems to have a feeling of stagnation in a certain part of the moment, this situation is not persistent, only in the development of the lesion is gradually obvious. 4, chest distension or tightness, and often accompanied by pharyngeal dryness. The patient complains that there is always a stuffy phenomenon in the front of the chest, which seems to be blocked by an object and makes the chest feel tight, which is especially obvious when swallowing food. Thoracoscopic minimally invasive technology The above early symptoms usually last for more than 3 months, and when they occur frequently, persistently and worsen, they are no longer early. If these symptoms appear, you should go to the hospital as soon as possible. The most advanced, safe and reliable minimally invasive thoracoscopic technique is used to treat esophageal tumor. The surgical method is: make a small incision in the chest, zoom in with the assistance of thoracoscopy, separate the tissues around the esophagus can get a better view than conventional open chest, hand-assisted ultrasonic knife cuts off the esophageal fibrous strips and nutritive blood vessels, without ligation, so the surgery is safer and faster. The surgery is characterized by: thoracoscopic minimally invasive small incision means the length of surgical access incision is 6~10cm, compared with the traditional open heart surgery, it is characterized by the incision is located in a relatively hidden part of the chest, and it is aesthetically pleasing, less traumatic, less bleeding, faster recovery, better healing, less deformity, less cost and so on.
