How is esophageal tumor stent surgery performed?

Generally, esophageal tumor stent placement is performed with endoscopic assistance by positioning the stent at the site of the narrowed lesion to improve the patient's ability to eat. The specific procedure is as follows:

1. The patient is placed in a lateral position, anesthesia is administered, drapes are applied, and fluoroscopic equipment is prepared.

2. A guidewire is inserted into the esophagus, followed by advancing a catheter over the guidewire.

3. The guidewire is withdrawn, contrast agent is injected, and the condition of the patient's esophagus and the required length of the esophageal stent are evaluated under imaging.

4. The guidewire is reinserted, and an endoscope is passed through the nose into the esophagus.

5. Under direct endoscopic view, the distal edge of the narrowed lesion is identified, while the position of the endoscope is simultaneously confirmed using fluoroscopy.

6. The endoscope is withdrawn to a position above the narrowed segment, with its location continuously monitored via fluoroscopy.

7. Under fluoroscopic guidance, the stent is advanced along the pre-placed guidewire and accurately deployed at the appropriate location within the narrowed esophageal segment.

8. The guidewire and endoscope are removed, the patient's face is dried, and the procedure is completed.

The procedure should be performed at a qualified hospital under the supervision of a skilled physician. After undergoing esophageal tumor stent placement, patients should rest adequately and consume liquid foods such as millet soup or egg drop soup to minimize irritation to the esophagus. If significant discomfort occurs after surgery, prompt consultation with a healthcare professional is recommended.
