GERD Retrospective Cohort
A retrospective cohort of approximately 5,000 patients with a confirmed diagnosis of gastroesophageal reflux disease (GERD) treated at Beijing Friendship Hospital was established using data extracted from the prospective clinical registry of the National Clinical Research Center for Digestive Diseases.
|
Data on clinical symptoms, treatment details, and long-term follow-up outcomes were retrospectively extracted from electronic medical records (EMRs) and institutional databases.

Pre- and Post-Treatment Improvement in GERD-HRQL Scores
Lasso di tempo: From pre-treatment to up to 10 years post-treatment
|
The Gastroesophageal Reflux Disease Health-Related Quality of Life (GERD-HRQL) questionnaire is utilized to assess patient outcomes as a quantitative variable.
The scale comprises 11 items, each scored from 0 to 5, with higher scores indicating a better quality of life (QoL).
Clinical success is defined as a >50% reduction in the total symptom score.

DeMeester Score
Lasso di tempo: From pre-treatment to up to 10 years post-treatment
|
The DeMeester Composite Score quantifies the severity of Gastroesophageal Reflux Disease (GERD).
It is calculated from 24-hour ambulatory esophageal pH monitoring using six acid exposure parameters: percentage of total, upright, and supine time with pH < 4; total reflux episodes; episodes lasting > 5 minutes; and the duration of the longest episode.
Each parameter is scored using the formula SV = (X - A) / SD + 1, where X is the measured value, A is the healthy baseline mean, and SD is the baseline standard deviation.
The total score is the sum of these six values.
Minimum value: 0. Maximum value: No fixed upper limit (unbounded).
In clinical applications, higher scores indicate more severe pathological acid exposure.

An SRI of ≥ 95% (often utilized interchangeably with Symptom Association Probability, SAP) is considered positive, providing strong statistical evidence that symptoms are not occurring by chance.
