Are manometric findings different between the patients with erosive and nonerosive disease?

Gastrooesophageal reflux disease (GERD) is defined as the pathological retrograde movement of gastric contents into the oesophagus. Various oesophageal motility disturbances which may be important in reflux are observed in patients with GERD. The main oesophageal motility disorder in these patients is ineffective oesophageal motility (IEM).

However, there are no data that conclusively link motility disorders with isolated distal reflux (IDR)...
