Description

Anti-reflux valve for preventing gastroesophageal reflux disease {Anti-reflux valve for preventing Gastro-esophageal reflux disease}

The present invention relates to an anti-reflux valve for preventing gastroesophageal reflux disease, and more specifically, to prevent gastroesophageal reflux disease, which is inserted or mounted on the upper part of a patient with gastroesophageal reflux disease to predict the potential effect of anti-reflux surgery. It relates to an anti-return valve for.

Gastro-esophageal reflux disease (GERD), which was recognized as a common disease in the West, is also increasing in Korea due to the westernization of lifestyle and dietary habits. As a result of a domestic big data survey (Ministry of Health and Welfare Health and Medical Research and Development Project HC17C0050), the prevalence rate from 11.8% in 2012 to 19.1% in 2016 showed a strong prevalence rate of 8% for 5 years.

The primary treatment for gastroesophageal reflux disease is drug treatment, but the number of patients taking 12 consecutive weeks at the standard dose without stopping the drug is estimated to be 110,000 in 2016, and the standard dose due to inadequate symptom control with standard dose medication. It is estimated that the number of patients taking more than twice the amount of drugs was 7,000 in 2016 (as a result of HC17C0050 of the Ministry of Health and Welfare Health and Medical Research and Development Project).

On the other hand, according to the results of a study of'Effect Comparison and Economic Evaluation of Surgical Treatment and Non-surgical Treatment', a health care research and development project of the Ministry of Health and Welfare, surgical treatment is symptom control in a prospective clinical study conducted in patients with refractory gastroesophageal reflux disease. , Treatment satisfaction and quality of life were statistically superior. In addition, it showed a decrease in medical cost and the number of medical use in the surgical group, and conclusively, surgical treatment was confirmed as the treatment alternative with absolute superiority in terms of cost effectiveness.

In addition, according to a survey by the'Korean Gastroesophageal Reflux Disease Surgery Research Group' under the Korean Gastric Cancer Association, about 100 antireflux surgeries are currently being performed per year. Considering the above prevalence and the number of long-term patients, it can be seen that the number of cases is less than 0.5%. Although the advantages of surgery are excellent in terms of effectiveness and cost, only a small portion of the surgical subjects are being operated because of the inconvenience of the tests that must be performed before surgery and the lack of a gold-standard test. This is because of the non-guarantee of the surgical effect.

Accordingly, there is a demand for the development of a medical device capable of replacing inconvenient tests and experiencing the effects of surgery by developing a diagnostic test method capable of predicting the effect of surgery in advance.
