Symptoms and quality of life in people with gastric inlet patches

Prevalence and Characterization of Dysphagia and Dyspepsia Symptoms and Assessment of Quality of Life in Heterotopic Gastric Mucosa (HGM)

Observational Knappschaft Kliniken GmbH · NCT07510984

This study will see if adults having a medically indicated gastroscopy who have heterotopic gastric mucosa (gastric inlet patches) are more likely to have swallowing problems, indigestion, or lower quality of life than those without it.

What this trial studies

This is a prospective, observational, single-center study enrolling adults undergoing clinically indicated gastroscopy. Participants complete pseudonymized questionnaires about oropharyngeal and esophageal dysphagia, dyspepsia symptoms, and health-related quality of life before their procedure. Endoscopic findings will classify participants as having endoscopically confirmed heterotopic gastric mucosa (HGM) or not, and the study will compare symptom patterns and quality-of-life measures between these groups. An exploratory analysis will examine symptom differences by histologic subtype when routine histology is available.

Who should consider this trial

Good fit: Adults (≥18 years) scheduled for an upper gastrointestinal endoscopy who can give informed consent and complete the pre-procedure questionnaires are ideal candidates.

Not a fit: People with previously known HGM, prior treated dysphagia, inability to undergo careful proximal esophageal inspection, or inability to complete questionnaires are unlikely to benefit from participation.

Why it matters

Potential benefit: If a clear link between HGM and symptoms is found, clinicians may better recognize a treatable cause of dysphagia or dyspepsia and target follow-up or therapy.

How similar studies have performed: Retrospective reports have suggested associations between HGM and symptoms, but prospective data and formal quality-of-life comparisons are limited, so this question remains only partially explored.
