AIM: To determine if the severity of gastroesophageal reflux disease is dependent on the size of a hiatus hernia. METHODS: Seventy-five patients with either a small(n = 25), medium(n = 25) or large(n = 25) hiatus hernia(assessed by high resolution esophageal manometry) were investigated using 24-h esophageal monitoring and a self-assessed symptom questionnaire. The questionnaire comprised the following items, each graded from 0 to 3 according to severity: heartburn; pharyngeal burning sensation; acid regurgitation; and chest pain. RESULTS: The percentage total reflux time was significantly longer in the group with hernia of 5 cm or more compared with the group with a hernia of < 3 cm(P < 0.002), and the group with a hernia of 3 to < 5 cm(P < 0.04). Pharyngeal burning sensation, heartburn and acid regurgitation were more common with large hernias than small hernias, but the frequency of chest pain was similar in all three hernia groups. CONCLUSION: Patients with a large hiatus hernia are more prone to have pathological gastroesophageal reflux and to have more acid symptoms than patients with a small hiatus hernia. However, it is unlikely that patients with an absence of acid symptoms will have pathological reflux regardless of hernia size.
