Surgery improves defective oesophageal peristalsis in patients with gastro-oesophageal reflux.

Postoperative manometry was carried out in 12 patients with gastro-oesophageal reflux associated with hypomotility of the oesophageal body. A Nissen fundoplication was carried out in all patients. After a median follow-up of 3.5 years, patients underwent clinical, endoscopic, radiological, manometric and pH-metric evaluation. Manometric results revealed an overall improvement in oesophageal motor function with an increase in the amplitude of deglutition waves and a decrease in the percentage of deglutitions without response. Six of the patients (one with complete motor failure) recovered normal peristaltic function. Non-specific oesophageal motor disorders may be secondary to gastro-oesophageal reflux and are reversible in nature.
