What are the examination methods for esophageal cancer

Esophageal cancer is also known as esophageal cancer. The incidence of esophageal cancer in my country ranks among the top in the world. Many people who have esophageal cancer feel depressed because the esophagus is a tube connecting the pharynx and the stomach. The malignant tumor that grows here is one of the common malignant tumors. Do you know something about esophageal cancer? Do you know how to check for esophageal cancer? Let us talk about the examination knowledge of esophageal cancer.

1. Examination of esophageal function

1. Gastroesophageal reflux test

① Esophageal acid perfusion test

②24-hour esophageal pH monitoring

③Lower esophageal sphincter manometry test

2. Esophageal motility test

① Esophageal manometry is suitable for patients suspected of having esophageal dysmotility.

② Acid clearance test, used to measure the peristaltic efficiency of the esophageal body in eliminating acid.

2. Esophagoscopy

Fiberoptic esophagoscopy has been widely used in the diagnosis of esophageal cancer. Esophagoscopy can directly observe the size, shape and location of the tumor, providing a basis for treatment for clinicians. It can also perform biopsy or endoscopic examination at the lesion site. Esophagoscopy combined with exfoliative cytology is an ideal diagnostic method for esophageal cancer.

3. Imaging Diagnosis

1. CT examination: CT scan can clearly show the relationship between the esophagus and the adjacent mediastinal organs, but it is difficult to detect early esophageal cancer. Combining CT with X-ray examinations can help improve the diagnosis and staging of esophageal cancer.

2. X-ray barium meal examination: It is one of the important means to diagnose esophageal and cardia tumors. It can provide 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 the esophageal lesion has invaded and the scope of invasion.

4. Esophageal exfoliative cytology examination

The esophageal exfoliated cytology examination method is simple, easy to operate, safe, less painful for patients, and has an accuracy rate of more than 90%. It is an important method for large-scale esophageal cancer screening. However, esophageal cytology examination should be contraindicated for patients with bleeding and bleeding tendency of esophageal cancer, or those with esophageal varices; esophageal exfoliated cytology examination should be performed with caution for patients with deep esophageal ulcers on esophageal cancer X-rays or combined with hypertension, heart disease and late pregnancy; patients with poor systemic conditions and excessive weakness should improve their general conditions before examination; patients with acute inflammation of the upper respiratory tract and upper digestive tract should control the infection before examination. Combined with X-ray barium meal examination, it can be used as a basis for the diagnosis of esophageal cancer, saving most patients from the pain of esophagoscopy. However, this method cannot be used when there is esophageal stenosis and obstruction, and esophagoscopy should be performed.

The above is some knowledge about esophageal cancer examination that we have prepared for you today. I hope it will be helpful to you.
