Stent Treatments for Trans-cardia Diseases

Saturday 24th March 2018 Back to list

Trans-cardia stents have two main indications. One is for the palliative treatment of cardia-fundus gastric carcinoma. This disease is one of the most common malignant tumor in China.  The patients have lost the operation chance and have poor prognosis. Clinically , stent implantation could alleviate patient’s swallowing function without the risk of causing esophagitis. Umbrella stent, anti-reflux stent with individual design are required by the market.

The process of customization stent:

1. Stent draft drawing or description from clinical side

2. Precise technical drawing from manufacturer --- This is the most important process and time and attention should be paid during this step

3. Production -- 3 working days

4. International delivery


The other indication of trans-cardia stent is for patient with cardia achalasia. This disease is dyskinesia of the esophagus. The incident of the disease is 2%~20% among esophageal diseases. Presently the treatments of this disease includes balloon dilation and stent implantation. Balloon dilation is to exert mechanic force on the cardia muscle. Which leads to the laceration of the cardia mucosa. The pressure  on lower esophageal sphincter is reduced and the obstruction is relieved.  Considering the long-term treatment effect, progressive dilation balloons and stents are preferred clinically. In most cases, stent with anti-reflux valve is chosen. Attention should be paid to the complications of stent implantation.

Tips for stent choosing in cardia achalasia.  

1. Stent is suggested to be retrieved bestly 2-3 weeks, maximum 60 days after implantation. Long time stenting is prone to stimulate granulation growth or cicatricial stenosis.

2. Choose stent with proper diameter that conforms to each individual case. Improper diameter shall lead to failure of operation or perforation.

Normally the LES is suggested to be dilated to 28~35mm.

3.  Treat the complications of vomit, subcutaneous emphysema, thoracic pain and anti-reflux symptoms with proper methods.  

4. Psychological console before and after operation, diet guidance and  careful observation after operation are also very important to raise the effectiveness and patient’s satisfaction.
