Background and objective:  To study the incidence and pattern of gastro‐oesophageal reflux disease (GORD) in patients with mild‐to‐moderate chronic obstructive pulmonary disease (COPD) using dual‐probe 24‐h oesophageal pH recording.

Methods:  This was a prospective study of 50 patients with mild‐to‐moderate stage COPD based on the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines. A detailed history of illness along with spirometry was done in all patients. In the study group, reflux symptoms were measured using a validated scoring system. All the patients underwent oesophageal manometry and dual‐probe 24‐h oesophageal pH recording.

Results:  Symptoms of gastro‐oesophageal reflux were present in 38 patients. Twenty‐four‐hour oesophageal pH monitoring revealed pathological reflux in 31 out of 38 symptomatic and 8 out of 12 asymptomatic patients. The overall …
