Do you know what tests are needed to confirm esophageal cancer?

The esophagus is a tube connecting the pharynx and the stomach. Tumors growing here are one of the malignant tumors, so many patients are quite depressed. So do you know some knowledge about the diagnosis of esophageal cancer? Do you know what tests are needed to confirm esophageal cancer? Let's learn about it together!

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.

Differential Diagnosis of Esophageal Cancer

The differential diagnosis of esophageal cancer depends largely on X-ray and endoscopic examinations in addition to medical history, symptoms and signs, and the final diagnosis needs to be confirmed by histopathology. Esophageal cancer needs to be differentiated from benign and other malignant tumors of the esophagus.

The above article tells you about the diagnosis and treatment of esophageal cancer. The above content is for reference only and cannot be used as a basis for diagnosis and treatment. Because each person has different physical conditions and the degree and symptoms of the disease are different, it is recommended that all diagnosis and treatment should follow the guidance of the doctor.
