Esophageal cancer after treatment of X-ray examination, (a) esophageal X-ray examination after surgery
Immediately after surgery and several days of X-ray examination, the main purpose is to understand whether the thoracic and abdominal surgery complications such as pulmonary infection, atelectasis, pleural pneumothorax and other product gas and liquid. Early anastomotic leak is suspected, it would be prudent to break the oil under consideration to confirm the diagnosis of esophageal imaging. At two weeks after the barium meal feasible to observe the situation and the presence of anastomotic fistula formation or other complication. After a few months to several years followed up with the primary purpose of observing the function of the situation anastomosis, with or without scar stenosis, cancer recurrence, and observation of thoracic esophagus stomach or colon, etc. on behalf of postoperative situation. Cancer recurrence at or near the esophageal anastomosis, the irregular filling defect or stricture College of Management, and even ulceration X-ray findings. Second, we must observe whether the mediastinal lymph node metastases, CT scan is the main screening method. In addition B-scan on the upper trachea, aortic arch on the blood vessels and supraclavicular lymph nodes had a higher detection rate of CT scanning as an important supplementary means. Esophageal cancer treatment and your door, especially in patients with hoarseness, the use of CT or B-check for mediastinal lymph nodes on the treatment efficacy, are of great help.
Followed up when they check in the liver, lung, kidney and other bone metastasis Ke. In addition to X-ray examination, the situation can be used for B-or CT scan.
Esophageal X-ray examination after treatment (b) radiation therapy during and after treatment, X-ray examination
X-ray examination of the purpose of observing and after treatment in the course of tumor response to radiation therapy, and objectively determine its efficacy. Well, after the end of treatment effect, the basic shape of the performance of esophageal smooth, barium through the smooth, mucous membrane can be seen, soft tissue disappeared. Above there is a significant improvement in recovery to be worse; if still not light the whole shape of the lumen, stenosis, wall remains rigid, then the disease is not controlled. Filling defect in a few cases such as change or even increased, indicating that the lesions progress to deteriorate. Such as ulcers Kanying deepened, highlighting the obvious, should be wary of perforation.
Comprehensive treatment by radiotherapy and surgical specimens of cases observed, showing the lumen and sometimes X-ray findings have been smooth, no obvious filling defect, but the muscle wall, there are still residual cancer. Also wall edema can sometimes result in radiation at the end of stenosis. Esophageal cancer after radiotherapy 80% local recurrence rate of about 65% recurrence within six months, 93% at 1 year, 1 year more than half relapse rare. Medical Oncology Hospital, one patient relapsed 10 years after radiotherapy. If it is found in the review of the luminal edge of the original lesion becomes uneven by the finishing, there filling defect, filling defect or associated with ulcers, should guard against recurrence. However, a few cases, the radiation resulting from non-cancerous ulcer (also known as benign ulcers radiation ulcer). Benign ulcer in the esophageal cancer fungating prone, and in the end of the X-ray radiation on the lesion completely subsided. Finishing esophagus who restored the chance occurrence of more benign ulcers. Cancer relapse, often marked contrast barium filling defect, ulcer not only the entire esophageal wall opposite, the upper and lower edge of the normal esophagus with no significant between the boundary line. Piercing deep into neighboring organs are more common. Benign ulcers are often no obvious filling defects, ulcers often the opposite esophageal wall to keep finishing. With the normal esophageal ulcers between the upper and lower edge of the clear dividing line, shallow ulcers, and less into neighboring organs. Difficult to identify the X-ray examination of the case, should further be confirmed by cytology or esophageal endoscopy.
Esophageal X-ray examination after treatment, in addition to radiation field according to the size and exposure, and whether factors such as through the lung tissue, there should be to observe whether there is radiation pneumonitis and pulmonary fibrosis change occurs.
