Question 1: How to perform esophageal cancer examination Esophageal cancer examination method Esophageal cancer examination method (1) X-ray barium meal examination Esophageal X-ray barium meal examination can show that the barium stagnates at the cancer site and the barium flow is fine in the diseased section Narrow; the esophageal wall is stiff, peristalsis is weakened, the mucosal lines are thickened and disordered, and the edges are rough; the esophageal cavity is narrow and irregular, the upper segment of the obstruction is slightly expanded, and there may be changes such as ulcer niches and excess defects. Superficial and small cancers are often difficult to detect with routine X-ray barium meal examinations. Using sodium methyl cellulose and barium for double contrast imaging can more clearly display the esophageal mucosa and improve the detection rate of esophageal cancer. (2) Fiber esophageal endoscopy can directly observe the shape of the cancer, and biopsy pathology can be performed under direct vision to confirm the diagnosis. (3) Cytological examination of exfoliated esophageal mucosa: Use a double-lumen tube cell collector with a wire mesh balloon to swallow into the esophagus, inflate the balloon after passing through the diseased section, and then slowly pull out the balloon. Take a smear with a mesh cover for cytological examination. The positive rate can reach more than 90%. It is often used to detect early illness and is an important method for large-scale esophageal cancer screening. (4) Esophageal CT scan CT scan can clearly show the relationship between the esophagus and adjacent mediastinal organs. The normal boundary between the esophagus and adjacent organs is clear, and the thickness of the esophageal wall does not exceed 5 mm. If the thickness of the esophageal wall increases and the boundaries with surrounding organs are blurred, it indicates the existence of esophageal disease. (5) Other examination methods: The application of toluidine blue or iodine in vivo chromoendoscopy has certain value in the early diagnosis of esophageal cancer. This method has the advantages of simplicity, accuracy in locating and determining the extent of cancer. A common examination method for esophageal cancer is cell detachment examination. This method is less painful, convenient to examine, and highly accurate. It mainly collects cells from the patient's esophageal lesions to help diagnose the severity and size of the disease. However, the patient's heart Patients with esophageal cancer, high blood pressure, or lung disease are not suitable for this examination. In addition, CT examination can be used to see whether the progression of the disease affects other organs. However, lymphatic metastasis cannot be detected, and X-rays are also available. Barium meal examination is more accurate and more effective. In short, these examination methods are commonly used by patients with esophageal cancer. I hope they can help patients and not be deceived by some small clinics.

Question 2: There are several examination methods for the esophagus and stomach. The current methods for examining the stomach include: barium meal B-ultrasound, three-dimensional in vitro gastrointestinal ultrasound, gastroscopy, and capsule endoscopy.

The differences between the two:

1. Barium meal B-ultrasound can only see the appearance, shape, location and space-occupying lesions, but cannot see the details of the inner wall of the stomach.

2. Three-dimensional in vitro gastrointestinal ultrasound examination uses a contrast agent to magnify the gastrointestinal lining to 300-400 times in detail to see the details of the inner wall of the stomach. It is suitable for children, the elderly and people with cardiovascular and cerebrovascular diseases who are not suitable for gastroscopy. However, it can only be used for examination and cannot be used to stop bleeding or stop bleeding. Resection and biopsy, the esophagus cannot be examined.

3. Gastroscopy is a comprehensive gastric examination, but the position, appearance, and shape of the stomach cannot be seen, and gastroptosis and hypertrophic gastritis cannot be clearly shown. The examination requires smooth intubation from the mouth, which is quite painful. Discomfort may be relieved in the next three to four days. Currently used for microscopic hemostasis, expansion, resection, and sampling biopsy.

4. Capsule endoscopy requires sufficient preparation before the examination to empty the digestive tract to prevent the capsule from being discharged smoothly. The esophagus, stomach, duodenum, small intestine, colon, etc. can be examined through a tiny camera. It is used to find unexplained bleeding, eliminate difficult problems, and people who are unwilling to undergo gastroscopy. Currently the only method in the world to examine the small intestine. However, hemostasis, resection and biopsy cannot be performed.

Question 3: What is the process of esophagoscopy? When the esophagoscope enters the middle esophagus, the head should be gradually lowered and slightly tilted to the right to suit the right direction of the esophagus. The thoracic esophagus is wider than the cervical esophagus, and can be seen on the left front of the esophagus at the intersection of the esophagus and the aorta. Pulsation, attention should be paid during inspection.

Question 4: How is esophageal cancer detected? Esophageal cancer examination methods: Esophagoscopy is one of the methods for examining and diagnosing esophageal cancer. Esophagoscopy can directly observe the size and shape of tumors. and location, providing clinicians with a basis for treatment, and at the same time, biopsy or microscopic brushing can be performed on the lesion. X-ray barium meal examination is a common method for detecting esophageal cancer. It provides reliable data for the study of early esophageal cancer. Combined with cytology and esophageal endoscopy, it can improve the accuracy of esophageal cancer diagnosis. X-ray barium meal examination of esophageal cancer not only determines the location, length and degree of obstruction of the lesion, but also determines whether and the extent of external invasion of the esophageal lesion, which is one of the diagnostic methods for esophageal cancer. Imaging diagnosis accounts for a high proportion in esophageal cancer examinations. Imaging diagnosis includes (CT examination, X-ray barium meal examination). CT scan can clearly show the relationship between the esophagus and adjacent mediastinal organs, but it is difficult to detect early esophageal cancer. Combining CT and X-ray examinations can help improve the diagnosis and staging of esophageal cancer. My reminder: Through the above introduction, I believe you have a certain understanding of it. Since esophageal cancer is difficult to detect in its early stages, it is recommended that you learn more about esophageal cancer so that you can detect, check, and treat it in time.
