Rome IV Diagnostic Criteria for Functional Dysphagia

Description

Evaluates the Rome IV criteria for diagnosing Functional Dysphagia. Diagnosis requires persistent difficulty swallowing (dysphagia), typically for solids only, that is non-odynophagic (not painful) and not explained by organic disease (structural, Eosinophilic Esophagitis, GERD, or major motility disorders). Symptoms must be chronic (onset >= 6 months, active >= 3 months).

Usage

rome_iv_functional_dysphagia(non_odynophagia_dysphagia, swallowing_solids_only,
                             no_structural_obstruction, no_eosinophilic_esophagitis,
                             no_gerd, no_major_motility_disorder,
                             symptom_onset_ge_6_months, symptoms_active_last_3_months)

Arguments

non_odynophagia_dysphagia	Numeric (0 or 1). Presence of dysphagia that is non-odynophagic (not painful). (1 = Yes).
swallowing_solids_only	Numeric (0 or 1). Does the dysphagia occur primarily for solid foods, not liquids? (1 = Yes).
no_structural_obstruction	Numeric (0 or 1). Has structural obstruction (e.g., stricture, mass) been excluded by upper endoscopy? (1 = Yes).
no_eosinophilic_esophagitis	Numeric (0 or 1). Has Eosinophilic Esophagitis (EoE) been excluded? (1 = Yes).
no_gerd	Numeric (0 or 1). Has Gastroesophageal Reflux Disease (GERD) been excluded (e.g., negative pH monitoring, no response to PPI)? (1 = Yes).
no_major_motility_disorder	Numeric (0 or 1). Have major esophageal motility disorders (e.g., achalasia, spasm) been excluded by manometry? (1 = Yes).
symptom_onset_ge_6_months	Numeric (0 or 1). Did symptom onset occur at least 6 months prior to diagnosis? (1 = Yes).
symptoms_active_last_3_months	Numeric (0 or 1). Have symptoms been active for the last 3 months? (1 = Yes).
