A Retrospective Analysis of Patients With Gastroesophageal Reflux Disease Based on a Prospective Clinical Dataset

2026. augusztus 5. frissítette: JunZhang, Beijing Friendship Hospital

Establishing an Innovative Cohort of Chinese Patients With Gastroesophageal Reflux Disease Based on the Prospective Database of the National Clinical Research Center for Digestive Diseases: A Retrospective Study

This retrospective, observational cohort study aimed to establish a comprehensive research cohort utilizing a large-scale prospective clinical registry. The primary objectives were to characterize the real-world demographic profiles, clinical features, psychological characteristics, and treatment patterns of Chinese patients with gastroesophageal reflux disease (GERD), as well as to evaluate post-treatment improvements in both GERD symptoms and psychological well-being. The study retrospectively enrolled approximately 5,000 patients with a confirmed diagnosis of GERD, with data derived from the prospective registry of the National Clinical Research Center for Digestive Diseases. Investigators systematically extracted data on baseline demographics, clinical presentations, objective diagnostic findings, preoperative psychological status, surgical complications, and longitudinal follow-up outcomes for all eligible patients. Ultimately, this study sought to provide high-quality, China-specific evidence to inform the precise phenotyping of GERD and to guide standardized, individualized clinical decision-making.

Tanulmányi populáció

The study population will be drawn from the clinical registry of the National Clinical Research Center for Digestive Diseases at Beijing Friendship Hospital, Capital Medical University. This retrospective cohort study will enroll approximately 5,000 patients with a confirmed diagnosis of gastroesophageal reflux disease (GERD). During the study period, all eligible patients documented in the registry who meet the inclusion criteria will be consecutively enrolled. The source population comprises patients presenting to Beijing Friendship Hospital for the diagnosis and management of GERD. This registry encompasses comprehensive data on clinical symptoms, objective diagnostic findings, treatment details, and longitudinal follow-up outcomes for all enrolled individuals. As Beijing Friendship Hospital is a major tertiary referral center in China serving a broad geographical catchment area, the study cohort is anticipated to be highly representative of diverse patient demographics and clinical

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.
